SUMMARY OF THE INVENTION The present invention relates to articles, such as door leaf and door leaf panels, that are surfaced by laser marking and ink jet printing to provide a high quality enamel product. The invention is further directed to methods and systems for making such articles. BACKGROUND OF THE INVENTION For example, residential and commercial building products are often made of engineered composite materials, including fiber-reinforced eight materials such as medium and high density fiberboard and slabs, and such as stencils, sheets, and cured polystyrene sheet molding compounds. Made by other "synthetic" materials such as (SMC). This money has a variety of applications, such as indoor door leaf and fan panels, drywall, countertops, _, wall panels, floors, wall panels, wall panels, ceilings, interior components, indoor use, and such as gates. , planking, siding, decoration: fence and outdoor use by frame. (4) = The material can be provided in the form of natural materials such as wood, stone and (4), etc., imI & into p province, but the lack of natural materials for synthetic materials @ == two for this reason, has been a lot of work Modify the surface appearance of the synthetic materials of the composite materials to simulate the beauty of natural materials 201029856 Li and complex. Conventional printing techniques, such as inkjet printing, apply an ink pattern to the surface of a composite material to mimic the general pattern of a naturally occurring material. However, synthetic materials with a single inkjet pattern may be aesthetically pleasing to attract more appealing consumers. Inkjet printed surfaces lack the presence of many natural materials and have a significant impact on their appearance. In addition, when used on uneven surfaces, roller printing and patching techniques suffer from a variety of problems. Uneven object surfaces will have specific characteristics, such as channels or grooves, which are located below the main surface of the article. Roller printing technology may not be able to touch such surface features below the main table + _ face. On the other hand, pigs may completely cover or bury these features. Other surface finish treatments such as sand blasting and veneering also have disadvantages such as high cost and the like. Laser marking technology on the surface provides another compelling alternative to the traditional processing of the above-mentioned building products. In general, the laser mark: 'or laser lining' is a non-contact power that changes the surface of the guard by relying on the laser light incident on the surface of the workpiece. The laser output energy, laser beam focus, and laser light Θ 即 (ie, traverse speed) can be adjusted to manipulate the degree of change. However, only lasers are still sufficient to produce natural surface simulations such as wood, stone or other natural materials. Even with the applied underlayer, the laser-treated surface is still too lax with certain pattern elements of real natural materials, such as the text of the wood when copying wood or the interlocking of the natural stone. Even from =, distinguish between real natural materials and synthetic materials, such as medium density fiberboard (FG) or granules treated with conventional lasers, etc., is still very easy. 4 201029856 In addition, there are a number of restrictions that can make money from traditional lasers to the difficulty of complex graphics. Due to the power capacity of conventional lasers and the economics of operating lasers in high-energy output states, articles such as buildings: ^ are manufactured, typically (4) operating at relatively low power rails. These power considerations, combined with the high density of certain workpieces such as the Guardian Wood Composite, give the laser beam a secret limit on the speed at which the pattern is created. Create expensive or special

The pattern may require more effort, which makes high-capacity manufacturing economically unfeasible.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 3 EMBODIMENT AND EMBODIMENT OF THE PREFERRED EMBODIMENT Reference will now be made to the exemplary embodiments of the invention Corresponding part. It should be noted, however, that the invention is not limited by the specific details, the representative device and method, and the illustrative examples shown and described in connection with the exemplary embodiments and methods. In an exemplary embodiment of a surface-marked article and related method, a method is provided wherein a first pattern design element is laser marked on one surface of an article and a second pattern design element is inkjet Printed on the surface of the item. The first design element is registered with the second pattern design element such that the overall pattern design can be a synergistic interaction between the laser mark pattern design element and the ink jet print pattern design element. The method of the present invention can produce a synergistic appearance of the final pattern design by orienting the first pattern design element and the second pattern design element in a predetermined orientation or associated with each other. On space 201029856, the predetermined orientation or association associated with the first and second patterning elements may involve its use, such as predetermined coordinates, on the surface of the item, logged, stacked, or juxtaposed. Aesthetically, these laser markings and inkjet printing pattern design elements produce an aesthetically pleasing effect that is revealed as a high quality simulation of a natural material that cannot be obtained by laser marking or inkjet printing alone. In some exemplary embodiments, the first patterning element and the second patterning element may also produce a texture contrast, as discussed below. Reference is now made to the drawings, in which like reference numerals illustrate the like elements throughout the figures, and FIG. 1 is a flow diagram of a method for marking the surface of an article in accordance with an embodiment of the present invention. According to the present invention, articles which can be used for printing include synthetic building members intended to imitate natural wood. Special consideration is given to outdoor gates and interior access doors, rest platforms and rest platform components, siding, panels, furniture components, etc., whether solid or composed of so-called hollow frames with opposing door panels door. The perimeter door frame includes the sills and tracks that define the sides and upper and lower sides of the door. A pair of door panels have internal surfaces that are secured to opposite sides of the perimeter door frame via welding, mechanical fasteners, and the like, as well as opposing exterior surfaces. As is known in the art, the hollow door can include additional support members and/or core materials (e.g., foam) disposed between the panels. Other building components that may be objects of the exemplary methods and systems described herein include furniture and cabinet doors, wardrobes and bi-fold doors, door trims, window frames, furniture components, furniture, picture frames, tables, and mold walls. Panels, siding, decking, wall panels, wall panels, drapes, window trims, architectural trims, flooring, etc. For purposes of explanation, the exemplary embodiments below are described in connection with building construction 201029856, particularly door leaf construction. It should be understood that the methods and systems described herein can also be used to mark items other than building elements and building elements. The exemplary embodiments and methods described herein are particularly useful for the use of engineered composite materials such as medium density fiberboard (MDF) and high density hardboard. Engineered composites generally contain cellulosic fibers or other materials that are often broken up in fiber mills, as well as resins and waxes that are optionally compressed at elevated temperatures and pressures. Fibrous fibers/substances can often constitute up to 90% by weight of this material. Such fibrous components are typically not necessarily wood fibers. Building resins are typically a thermoset. An example of an engineered composite material is disclosed in U.S. Patent No. 5,344,484. Examples of other materials can be handled using the systems and methods embodied herein, including glass fiber reinforced sheet molding compound (SMC) polyester fibers, paint and primer on substrates, sheet polymers, sheets, paper With natural materials such as wood. As shown in Fig. 1, in a first step, a first pattern design element 102 is registered with a second pattern design element. In one embodiment, the first pattern design element can be associated with a first pattern design element file and the second pattern design element can be associated with a second pattern design element file. In order to achieve a desired orientation or association between the first pattern design element and the second pattern design element, the first pattern design element file and the second pattern design element are for visual impression (ie, aesthetic) and tactile impression (ie, touch In terms of sensation, it can be matched on the system to produce one or more uniform pattern design files. 9 201029856 The designation referred to here covers both decorative and artistic designs. The pattern design can include simple geometric shapes and/or high complexity art representations. The pattern design may include a repeating pattern such as a diamond, a houndstooth 0, or the like, or a non-repeating pattern such as a flower pattern. A pattern design that mimics the appearance of a wood grain pattern and features made by a planer or woodworker is particularly suitable. As discussed in more detail below, exemplary embodiments of the present invention allow for advanced, highly artistic graphic design printing and marking to enable the inclusion of quality products currently available on the market in an economical high output industry. Production methods to manufacture. After the first pattern design element is registered with the second pattern design element Lu 102, i.e., a predetermined orientation or joint is achieved, the first pattern design element is laser marked 1〇4 on the surface of an article. A laser marking printer (ie, a laser scriber) containing a laser and a laser controller can mark - or multiple of the pattern design elements to the surface of the item - or more On the part. Each pattern design component can be associated with a pattern design component file. During the laser marking process, the laser beam causes a visually perceptible change to the surface of the article, typically by fading, ablation or etching of the surface of the article that causes the coating or the coating to be unfinished. This visually perceptible change is typically in the form of a groove having a depth that extends partially through the article or article, but not through the depth of the article. (This is not intended to exclude the use of lasers for separate cutting operations.) This groove can be combined into a channel, trough or ditches, holes or other depressions. Grooves formed into channels/ditches having an extended length may be disposed on the surface of the article to create an item (eg, a door leaf structure) that has been satisfactorily filled, made of woodwork, or combined by a plurality of elements 10 201029856 That is, the appearance of 'relative to the single crystal structure'.

Laser beams can be combined to create simulations that mimic the feel or feel of natural materials and/or traditional processing techniques. For example, the Ray=Bundle can be controlled to give the recessed area a careful imitation of the texture of the non-synthetic material or the relatively rough texture of the material, such as wood that has not been polished (4) or wood: wood. The surface plane of the right article is relatively smooth before the laser marking, so the surface area of the object surface is not maintained by the laser marking, and the surface area exposed by the laser is strongly formed by the laser marking. Pure sense. In many cases, the surface topography of the rough regions can be visually characterized (from the naked eye) as irregular or non-uniform. Laser markings, especially when applied to the petals, form a plane that appears to reveal the ends of individual wood fibers. The texture contrast between adjacent surface areas contributes to a highly desirable visual impression of the graphic design and adds to the overall artistic quality of the product. The laser marking can be applied to the substrate of the article or any layer of the final processing applied. The laser marking can partially or completely penetrate any layer or substrate. The depth of the laser marking can vary from shallow print on the surface to full penetration of the substrate. In one embodiment, the laser marking can penetrate into the bottommost coating, but not into the substrate. In another implementation, the laser mark penetrates the top coating' but does not enter the base coat. In other implementations, laser markings can penetrate into combinations with these other depths. Finally, in step 106, the pattern design element is inkjet printed onto the surface of the article. An inkjet printer comprising one or more jet printheads and an inkjet printer controller can inkjet print the second patterning element onto one or more portions of the surface of the article 11 201029856. In an exemplary embodiment, the resin and wood fibers of the MDF are _ in the course of laser marking - an mdf article. Eliminate the depth and change the color of the painting to the standard color. When the ablation zone is inkjet printed, the combination of laser marking and inkjet printing achieves a synergistic effect that is more advanced than using one of the techniques alone. In addition,

Light is reflected in a manner that is marked by a laser and is coated with ink to indicate that the ink is not subjected to the marked area of the laser. This contrast is useful for detecting the depth of the laser zone. The ink can be applied to the exposed fibers of the mill' which provides enhanced visual and tactile effects that were previously unavailable. Laser marking and inkjet printing procedures are not limited by the substrate and may include MDF/hardboard, SMC fiberglass polyester, coatings, basecoats on substrates, paper, flaky compounds, sheets Items such as natural wood. In various embodiments, laser marking and ink jet printing can be performed in any order or substantially simultaneously. In the embodiment depicted in Figure 1

A portion of the surface of the object is first scanned with a laser and then printed with the ink as a flow diagram of a method for marking a list of items in accordance with another embodiment of the present invention. As shown in Fig. 2, the second image is inkjet printed onto the surface of the article 206 before the leaf pattern element is laser marked onto the surface 208 of the article. As indicated by the dashed lines in Fig. 2, the laser marking and inkjet printing of the pattern design elements can be performed in a plurality of stages. (The thesaurus "I-I" is second, the design is not intended to indicate the order in which the design is created or applied to the surface 12 201029856.) The entire surface of the item can be marked by laser, or some surface. Similarly, the entire surface of the article, or the surface of certain parts of the article, can also be inkjet printed. In some embodiments, the laser marking process may be preceded by inkjet printing (10), for example, in all or part of the second patterning component to be inkjet printed to some or all of the laser markings first When the pattern is designed on the component.

As shown in Fig. 2, after the first pattern design element 202 is registered with the second pattern design element, it is convenient to prepare the surface of the article. In one embodiment, a base coat is applied to all or part of the surface of the article. This base coat, for example, is ready for inkjet printing on the surface of the article. Figure 3 is an elevational view of an article of a door leaf structure in accordance with an embodiment of the present invention. Figure 3 contains a door leaf structure 3〇〇. As shown in Fig. 3, the plurality of channels 308 provide the appearance of the door leaf structure 3 by a plurality of vertical slats 3〇4a, 304b and a plurality of horizontal slats a, 鸠赖朗. The vertical slats 304 and the horizontal slats 306 collectively define a major plane 3〇2. As illustrated in Fig. 3, the channel 3〇8 is formed in a rectangular or square shape (as viewed in plan) to define the contours of the plurality of inner panels 31〇. For the purposes of the text herein, the main panel is surrounded or otherwise surrounded by the main panel 3_complete external article surface area. The major plane 302 and the outer surface of the inner panel 310 may be coplanar with each other. The primary plane 302 and the interior panel 310 can have a smooth outer surface and the area corresponding to the channel 310 can have a rough outer surface to mimic the texture of the wood made from wood or wood. The door leaf structure of Fig. 3 includes ten (ι〇) inner panels 31G. The ten interior panels 31 of the illustrated embodiment are square 13 201029856 and are identical to each other. In other embodiments, a surface item can include one or more interior panels 310. In addition, the interior panels 310 can have other shapes and can be identical or different in shape.

Fig. 4 is an enlarged view of a fragment of the door leaf structure article of Fig. 3. As shown in Fig. 4, the trenches 308 can be laser etched very finely and substantially concentrically with one another to provide the appearance of the perimeter of the interior panel 310 that has been expertly planed or tied to a woodwork. In addition to laser marking the trenches as described above, a variety of patterns, including intricate and flamboyant design patterns, can be indexed in a variety of articles such as architectural products. By way of example, the inner panel 308 of the door leaf structure 300 includes a highly complex or high-quality design that is laser etched between substantially concentric channels 308, such as the strand design 312. It should be understood that other complex design lasers may also be marked on the surface of the article. For example, for wood simulation, a small depression on the surface of the item can be created by laser marking. These small depressions mimic the look or feel of hibiscus found in natural wood, such as oak or mahogany aphids.

Laser prints can be created in addition to wood or wood predise patterns. For example, 'the groove that marks the laser in the surface of the object is configured in a grid pattern, called the grid pattern of the channel of the rough laser marking surface with the appearance of the imitation joint agent, to simulate the wall. Or the edge of the floor structure (4) the edge of the block. Shoot the texture created by these gullies to provide a feeling of touch and touch compared to the thick ribs of the grout or plaster. The laser marking area is smoothed to realistically simulate the appearance of the material (4). Also for example, in the exemplary embodiment of the invention, the grooves may be marked along a non-linear path to simulate the edges of the natural uncut stone. A supplemental second pattern element is inkjet printed in a registered relationship with the laser-marked pattern design element to create an enhanced or synergistic overall patterning effect. Different patterns can be applied to the laser marked area and the non-laser marked area ' to enhance contrast. For example, in the case of wood simulation, brighter tones and inkjet prints can be printed with more visible texture patterns.

On the smooth (ie non-laser mark) area of the surface of the item, not on the rough (ie, laser mark) area. The erroneous vertical detail of a complex design that is costly or difficult to achieve laser marking can be used as a second pattern design component registered with the __pattern design component, and inkjet printed on the surface of the article. The wood grain pattern of oak walnut, cedar, mahogany and other wood species can be inkjet printed on the surface of the item to simulate the real wood = surface appearance. It is even possible to ink-jet print exotic wood patterns such as leopard wood patterns and other patterns. Inkjet printing can be laser marked - such as a twisted rope design 312 to speed up manufacturing. The enhanced overall pattern design achieves a three-dimensional effect. Fig. 5 is a cross-sectional view taken along line V_V of Fig. 3; In some cases, due to manufacturing and/or economic constraints, sometimes the grooves formed in the surface of an article via laser markings are relatively shallow and lack substantial depth. The shallow groove j alone does not necessarily result in a true impression of the 维 \ 生 生 生 生 生 或. In many cases, this item is a surface-marked μ-adjustable man-made body, which is quite obvious. In order to grant the laser marker the strong dimension and authenticity of the design elements of Figure 15 201029856, a second pattern design element is inkjet printed on the surface of the article in the manner of laser marking the first pattern design component. . In some embodiments, some inkjet printers can be assembled to apply patterning elements to the laser marking recesses. In a particular embodiment of the invention, one or more inkjet printed graphic design elements are designed to create an enhanced three dimensional impression, such as a laser marking first pattern design having a greater depth of depth than its actual depth Such an illusion (or user perception). Inkjet printing pattern design component can

Simulate shadows or illumination for this purpose. To create this three-dimensional effect, the inkjet print pattern design elements can be applied within the boundary of the channel, or directly adjacent to the channel outline, i.e., on the edges of the outer surfaces of the main flat (4) 2 and (four) grids 31. The method of being used alone on the surface with the logo design element can produce a highly decorative 'realistic imitation more expensive j material \ wood stone and ceramics, etc., the appearance of the item. By using these methods, such as _ with a pressure type and a planer, etc.

The high cost of the alternative to the feature is not necessary. Figure 6 is a diagram showing the flow of a method for marking the surface of a surface according to another embodiment of the present invention. The method of creating a pattern design is shown in Fig. 6. Using the model, „„ and designing the pattern A method of converting to a computer readable medium for use in a laser image.

In the μμ pull ink printing, here, the laser will be selected for the laser marking, and the pattern of the feature and/or the area of the pattern will be referred to, and the pattern selected by the inkjet printing will be selected. Design features and/or blocks are referred to as the tenth design 7L piece. The first pattern 5 and the first pattern 5 can be tied up in a unified image (4), or stored in separate image files and stored in the implementation shown in Figure 6, the pattern design is divided into mine. The template and an inkjet pattern template. The laser pattern template includes the pattern design features that are processed using a vector-based program. In other words, the laser-patterned design elements include lines and curves that define the wheel I of the pattern and its main linear and curved features. Vector-based ^ and or more deductive programs can create several vector files for these features. The pattern design elements that are marked by laser include three-dimensional "fill" features ^^* such as gradient contours and surface textures. A raster-based interpreter can create one or more raster files for these features. As shown in Figure 6, a vector file 604 is created by AutoCAD®, a vector-based algorithm developed by AutoDesk®. Arb〇r Image's ® 17 201029856-based program, the Cutting Shop, also creates a vector file 606 for features such as special unique shape design fills. It may be difficult or impossible to prepare these unique shape design fills with AutoCAD®. The Cutting Shop is a commercially available product from Arbor Image that promotes cutting and engraving applications. In other embodiments, other vector-based programs can be utilized to create laser-markable pattern design elements. Still referring to Figure 6, Adobe Photoshop® is utilized to create a raster image of a grayscale image containing three-dimensional "filled" features, such as gradient contours and surface textures. Adobe Photoshop® creates a grayscale image file with features such as this spring. From this grayscale image, Techn〇lines' raster-based program Technoblast® creates computer-readable instructions 608 for controlling the laser path and power of laser-marked "filled" features. After multiple vector files have been created, they can be “teared” or converted to a form that is understandable by laser markers or inkjet printers. The raster- and vector-based program Exodus was used to tear up the files 612 received from the AutoCAD®, Cutting Shop and Technoblast® programs. The Exodus program tears these files into a _dxf pattern (vector) file 616 and a tbf pattern (raster) file 618 that can be utilized by the laser marker. Laser markers and inkjet printers are typically equipped with appropriate software to convert computer files into the language of the laser and printer manufacturer. The ink jet pattern stencil can also represent the color of the pattern design and the fill pattern of any unsuitable processing. As shown in Figure 6, Adobe Photoshop®, a deductive program based on the light 18 201029856, was used to create a raster file 610 containing colored (eg, hue, shading, background color) and printed information. Next, the raster file is torn to the inkjet printer 614. As shown in Figure 6, Wasatch Computer Technologies' software program, Wasatch SoftRIP version 5.1.2, tears the raster file into a compatible format for the inkjet printer controller. ❿

After the laser pattern stencil and the inkjet pattern stencil have been torn into the appropriate format, the pattern design elements are printed onto the surface of the article by laser markings 104 and ink jets to produce a finished sample 62. The - (10) used to pattern design laser markings and inkjet printing on articles such as building components are shown in the P~u diagram, which uses a high speed, high power laser and inkjet printer.

When laser beam 708 is incident on mirror 804, rotation of X-axis mirror 804 causes laser beam 708 to be incident on mirror 808 for movement along the x-axis. The laser controller 704 can be configured to control the rotation of the x-axis mirror 804 caused by the x-axis current detector 802 by the energy supplied to the x-axis current detector 802. The laser beam 708 is deflected by the x-axis mirror 804 and directed to a y-axis mirror 808 that is rotatably mounted on the y-axis galvanometer 806. The y-axis galvanometer 806 is adapted to rotate and cause rotation of the y-axis mirror 808. Rotation of the y-axis mirror 808 causes the laser beam 708 to be incident on the mirror 808 along the y-axis. The laser controller 704 can be configured to control the rotation of the y-axis mirror caused by the y-axis galvanometer by adjusting the energy supplied to the y-axis galvanometer 806. The speed and power of the laser 708a are adjusted, and a high resolution pattern element is produced by the laser marker. For example, the laser controller 704 can rotate the x-axis galvanometer 802 and the y-axis galvanometer 806 at high speed to increase the speed at which the guided laser beam 708a traverses the surface of the door leaf structure 300. The speed of the guided laser beam 708a determines the appropriate power level of the laser when the pattern is printed by the laser. Certain features of the pattern design, such as complexity, intricate detail, and design depth, can affect how the pattern design laser is marked onto the door leaf structure 3〇〇. 22 201029856 Laser beam 708 is deflected by y-axis mirror 808 and directed through a focusing device 810 adapted to focus laser beam 708 into a guided laser beam 708a. The focusing device 810 can include a multi-element planar focusing lens integration that optically traverses when the guided laser beam 708a moves across the door leaf structure 300 to laser mark a pattern design component such as the channel 3〇8 The point of focus (ie, focus) is maintained on one plane. Although not shown, the lens focusing device 81, the mirrors 8〇4, 8〇8, and the current detectors 802, 806 can be housed in a galvanometer block. Work platform 716 can be a solid substrate or even a fluidized bed. The door leaf structure 300 is placed on the work platform 716. The door leaf structure 3 includes a visible, laser-markable and ink-jet printable surface that corresponds to the outer surface of a door leaf skin in an exemplary embodiment. The work platform 716' can be vertically adjusted to adjust the distance from the lens 81 to the printable surface 718. The laser beam 708 is directed by the mirrors 8A, 808 such that the guided laser beam 708a is incident on the surface of the door leaf structure 3A. The guided laser beam 7〇8a is typically guided along a path that is generally perpendicular to the laser-markable surface 718, but can be adjusted between the guided laser beam 708a and the laser-markable surface. The angle of 718 is, for example, from about 45° to about 135. And complete different patterns. The relative movement between the guided laser beams 7〇8& incident on the laser-markable surface 718 of the door leaf structure 300 causes a pattern such as the channel 12 to be laser marked on the laser-markable surface. On 718. As used herein, relative movement may include the movement of a laser beam that is guided while the door leaf structure 300 remains stationary (eg, using a mirror system, absolute), a laser beam that is guided by a laser bow. 7嶋Maintains 23 201029856 A combination of movement of the door leaf structure 300 at rest, or simultaneous movement of the guided laser beam 7〇8a and the door leaf structure 300 in different directions and/or different speeds. According to an exemplary embodiment, a pattern design is scanned or otherwise entered into the workstation computer 702 and converted to a suitable format, such as digitization. Information relating to the laser marking features of the pattern image is communicated to the laser controller 704 along with instructions to the laser marking pattern design elements on its corresponding section. The laser controller 704 then controls the movement of the galvanometers 802, 806 and the energy output of the laser 706 to direct the first pattern design component to the appropriate power and speed for high flow rates. On the working surface 718 of the door leaf structure 3〇〇. The laser beam power, laser beam size, and laser beam speed can be controlled to avoid any unwanted over-processing results, such as full carbonization, burn-through, and/or melting of the door leaf structure 300. The system can include a reservoir 718 for injecting a gas, such as an inert gas 4, into the work area. The amount of gas can be controlled by workstation computer 702, laser controller 704, or some other device. In an exemplary embodiment, a 2,000 watt laser is coupled to an ultra high speed laser scanner capable of moving the laser beam 7 〇 8a over the printable surface 718 by more than 3 megameters per second. 71〇. In other embodiments, lasers having other power metrics up to more than 2,5 watts are used, and laser scanners having different scanning speeds of up to 65 meters per second. The scanning speed of 30 to 50 meters per second can be used to mark the unit cost of the unit cost per square inch of readings per square inch. As referred to herein, "speed" is the speed of the guided laser beam 7 relative to the surface 718 of the shield. The working surface 718 can be moved by moving the guided laser beam while maintaining the working surface 24 201029856 718 in a static position, by maintaining the guided laser beam 7 〇 8a in a static position, The relative speed is controlled by simultaneously moving the guided laser beam 7〇8a and the working surface 718 in different directions and/or at different rates. According to an exemplary embodiment, a high speed, high power laser is used to form a first patterning element on the surface of the door leaf structure 300. Laser

The 706 can be a high power c〇2 laser having an output power of 500 W, 10 W (lkW), 2000 W (2 kW), 2500 W (2.5 kW) or greater. The laser power output referred to herein is continuous to distinguish it from when the laser device has a temporary energy surge or when the laser is paused. This continuous power can be changed by adjusting the power setting on the laser 706. The frequency of the laser beam 708 is typically in the range of, for example, 1 〇 to 6 〇 kHz. An exemplary commercial laser, such as a 2.5 kW C02 laser, model number DC025, is available from Rofin-Sinar Technologies. In order to provide high scanning speeds, for example from 30 to 50 meters per second, a galvanometer driven laser system with 1,000 to 2,500 watts is commercially available with high temperature coating. The lightweight mirror system is especially useful. One such commercially available lightweight mirror system is the ScanLab AG, the PowerSCAN33 Be model, and a 3-axis galvanometer scanner with a 33 mm Be mirror. It is believed that the high temperature coating is a physical vapor deposition alloy. The lightweight 铍 substrate is coated so that the mirror can reflect more than 98% of the C〇2 wavelength, 10.6 microns. The lightweight mirror system enables the galvanometer to move the guided laser beam 25 on the printable surface 718 in a repeatable but efficient manner. Thus, the scanning speed of a laser system can be higher than the level of laser scanning speed achieved by a linear driver or a conventional galvanometer mirror. Compared to the maximum scanning speed of 4 to 5 meters per second achieved using conventional laser engraving techniques, the laser scanning speed of over 65 meters per second can be achieved with such a lightweight mirror system. In one example, a system for laser-engraved plastic sheets in a continuous process for mass production can be included in a 2,5 watt watt laser that is operated at high speed and Attached to a working surface of 50.8 cm (2 〇 pairs) to meet the line speed of this procedure. However, A _ for the mass production, the appropriate laser markings of 3 envelopes by 8 inches of internal sector fans' use of multiple laser Iss or a linear motor to cover the entire work surface can be more efficient. Regardless of the configuration, the laser power of greater than or equal to Erwat (eg, from 500 to 2, 5 GG) and the laser scanning speed of greater than or equal to the fiscal scale per second (eg, 10 to 50 meters per second) The unit cost of the rotten pattern on the building product produces a satisfactory economical pattern. The laser speed can be increased by from 3.8 meters per second to, for example, 5 feet per second, and the actual unit is reduced from one level per square inch to one cent per square inch of centimeters. The cost is reduced. Systems and methods for marking objects on a surface can be implemented using a variety of other laser systems and scanning devices having modifications and alternatives to the layout and components of the layout and components shown in FIG. An example of a laser system is disclosed in U.S. Patent Application Serial No. 2/7/1,817, issued to Costin et al., and issued to Costin et al.

The effect of controller speed on the width of the laser power change for the two separate pattern images is demonstrated by the Lang and Shame below. The nth table contains the thunder for each of the 32 thunder rays, and the tread (4) table contains the information of 6 rays per mile. For example, a laser capability is required to change 30 201029856's pattern image with 32 rays per mile per 2 pixels, which is the maximum λ laser of 15m/s at a controller speed of 10,000 pixels per second. Scan speed (see Table II). In this example, to double the laser speed to 3 〇 m/s, the controller should have a processing power of 20,000 pixels per second. When the Rays per mile is increased (4) (comparing the nth table with the mth table), the controller speed becomes more important' to maintain high lightning ray catch.
