Definitions

  • the invention relates to a method for controlling the gloss of an image carrier substrate transferred and fixed toner image according to claim 1, and a digital image recording device according to the preamble of claim 15.
  • a well-known digital image recording method is electrostatic printing which a latent electrostatic image is developed by charged toner particles. These are transferred to an image receiver substrate, hereinafter substrate for short. Subsequently, the developed and transferred image on the substrate is fixed by the Toner particles are melted by applying heat.
  • Dry toners are often used, the particles of which have an average diameter of 10 ⁇ m.
  • hot rolls are often used, which are brought into contact with the toner image.
  • a release agent for example silicone oil
  • a release agent for example silicone oil
  • each of the toner layers made of a polymer material has a thickness of 30 ⁇ m can have.
  • the gloss of these toner layers which is very important for the image quality, is determined by many factors, for example by the surface structure of the hot rollers, the fixing temperature and the toner properties.
  • a heated one is used instead of the hot one Ribbon used to melt the toner image.
  • the toner image is - after it has passed the heating area - cool down and harden before moving on from the previous one hot surface of the tape is separated.
  • This enables simple and reliable Detach the toner image from the belt.
  • the structure of the toner image surface is by melting identical to the surface of the tape. To be a very smooth To be able to realize a toner surface that is accompanied by a high gloss is therefore a must very smooth tape can be used.
  • a high gloss of the toner image is not necessary for all applications. For example is only a little gloss on an image carrier substrate formed from a matte paper of the toner image required.
  • One way to change the shine is to use only a few heated rollers with a defined surface roughness.
  • the Rollers touch the surface of the toner image and shape their surface structure in it Toner image.
  • To change gloss rolls with different roughness must be used.
  • Another disadvantage of the hot rollers is that they are subject to wear and after a period of time need to be replaced, which involves costs is.
  • the mechanical contact between the toner image or the Image carrier substrate and the rollers also leads to the fact that the toner image often on the outer surface the rolls stick. In most cases, therefore, is a cleaning system required for the roles.
  • Another object of the invention is to provide a digital image recording device specify at which a precise setting of a desired toner image gloss is possible.
  • the cost of the image recorder is said to preferably only be small.
  • a method is proposed that has the features of the claim 1 has.
  • This is characterized by the fact that the toner image is initially known Is transferred to the image carrier substrate and fixed thereon and only subsequently in a second step on its surface or near its surface Area either completely or at least partially melted.
  • This takes place according to the invention in that at least the already fixed toner image a further time heat is supplied, which is preferably contactless by means of a Radiation device takes place.
  • the melting of that fixed on the image carrier substrate Toner image on its surface causes the liquid toner to start flowing, so that - when it has completely melted - it is a very smooth surface and therefore a high one Has shine.
  • the degree of melting that is, to what extent the toner image its surface is melted, and by the duration of the melting, so how as long as the toner layer is kept in a liquid state so that it can flow away, enables precise influencing of the toner image gloss.
  • the already fixed toner image does not have to be completely melted again to influence its gloss, but only the top layer, so that the energy required for this is only low is.
  • What is particularly advantageous about the method according to the invention is that it is practical every gloss level is adjustable, i.e. from matt to high gloss, without having to add one Replacement of parts of the fuser is required.
  • the fixing device for fixing the toner image on the image carrier substrate for the first time has a heating device with at least one hot roller, this can be hot Roll to be used for the first fixing of practically all toner images, independently of what gloss the respective toner image should have when it is finished is.
  • the gloss of the hot rollers on the image carrier substrate If the toner image is to be changed, the surface of the Aftertreated toner image in the desired manner, ie melted and then cooled down again, so that depending on how high the degree of melting is and the Time period for how long the toner layer is kept in the liquid phase, then the toner image has a higher or reduced gloss compared to the initial state.
  • the already fixed toner image is preferably reheated with With the help of a contactless heating / melting process.
  • the advantages of the invention Procedures are of course also established when the actual Fix the toner image on the image carrier substrate instead of using hot Rolling or the like takes place by means of a radiation device, that is to say without contact, because the radiation device only applies electromagnetic radiation to the toner image and is not brought into mechanical contact with the toner image.
  • the gloss of the is already set on the image carrier substrate fixed toner image by means of a preferably non-contact Heating process.
  • the "degree” of remelting of the surface of the one already out of the image carrier substrate fixed toner image can be up to 100%. In this case, the toner image surface is completely melted and can flow away, leaving a very smooth Surface and thus a very high gloss results.
  • the degree of melting can also be less than 100%, that is, the surface of a toner layer is only partially melted, so that there are still solid parts of this toner layer in the "Melt" are located. If this state of the toner image is frozen by the For example, if the toner image is cooled rapidly, a toner surface with a certain roughness and thus a correspondingly lower gloss than a smoother one Toner image surface.
  • the Two successive electromagnetic radiation pulses are applied to the toner image is, the duration of the first radiation pulse greater than the duration of the second radiation pulse.
  • a "radiation pulse” a flash of light that only briefly the toner image acts.
  • the radiation of the flash of light lies in a certain, preferably adjustable wavelength range, especially in the UV range.
  • the first The radiation pulse can be very short, for example, and a very high energy intensity have, so that the surface of the toner image is melted while by the second, preferably very short-lasting radiation pulse, a reduction in Gloss of the toner image surface is reached.
  • the intensity of the two radiation pulses can therefore be varied to influence the gloss. At least a high intensity of the first radiation pulse can initially lead to a high gloss, whereby this gloss can be specifically changed by the second radiation pulse.
  • the toner image by means of a the toner image is fixed mechanically contacting heating device and that in one subsequent processing step, the fixed toner image with electromagnetic radiation or more radiation pulses is applied.
  • the toner image has different areas Shine on.
  • a pulsed or Continuous electromagnetic radiation is emitted in the areas of the toner image have a higher toner density, the gloss reduces more than in the areas with lower toner density. The reason for this is that a toner layer with higher density better absorbs electromagnetic radiation. Because of the different, toner densities dependent gloss reduction is more even over the entire toner image Adjustable gloss.
  • the gloss is influenced of the toner image fixed on the image carrier substrate with pulsed or continuous electromagnetic radiation in the UV range.
  • the radiation from color toners is absorbed essentially uniformly, while, for example, the image carrier substrate made of paper radiation in UV range absorbed very little. Due to the restricted wavelength range The radiation can thus be ensured that the paper by this radiation, the can have a high intensity, is not damaged.
  • paper absorbs the radiation very well, so that with high radiation intensity damage to the paper cannot be ruled out can be.
  • the electromagnetic Radiation is filtered such that the toner image is only exposed to radiation in the UV range becomes.
  • An embodiment of the method which is characterized by that the toner image with several successive electromagnetic radiation pulses is applied, the time duration and / or intensity of the radiation pulses is different in length or height.
  • each of the radiation pulses has sufficient energy, around the toner image or the region of the toner image close to the surface to heat so that it melts and the toner can flow away.
  • Another one An embodiment variant provides that the energy of each individual one of the radiation pulses is not sufficient to melt the toner and that the toner image only then melted becomes when it has been exposed to several radiation pulses. Every single one the radiation impulses can therefore only a part of the total amount of energy in the Enter the toner required to melt the toner. It is more advantageous Embodiment the energy of each radiation pulse equal.
  • the first radiation pulse is the largest Has energy and that the energy of each further radiation pulse is less than that of the previous radiation pulse.
  • At least two successive ones Radiation pulses are applied successively to the toner image become. So there is a pause between the radiation pulses, so that the Scatter heat introduced into the toner image by the first radiation pulse can before the second radiation pulse is applied to the toner image.
  • three radiation pulses with an energy of 0.5 J / cm 2 are applied to the toner image with a duration of 0.5 ms and a pause between two successive radiation pulses of 5 ms.
  • the first radiation pulse heats a toner layer with a thickness of approximately 3 ⁇ m in the region of the toner image near the surface, which leads to a limited smoothing of the toner image surface.
  • the at least partially liquefied toner layer changes to the solid state and in approximately 5 ms after the first radiation pulse, most of the heat has dissipated in the toner image.
  • the second radiation pulse is applied to the toner image, which has sufficient energy to melt the uppermost toner layer again, and then the third radiation pulse, which melts the toner layer again if necessary. Additional radiation pulses can be applied to the toner image if necessary. It is important that the top toner layer is heated to a sufficiently high temperature for a sufficiently long time to achieve a high gloss, so that this toner layer smoothes to the desired extent and thus a high gloss is obtained.
  • the energy is each individual of the radiation pulses only so large that damage to the toner image as a result overheating of the toner, causing thickening or oxidation of the toner material leads, is avoided.
  • At least one, preferably several short and low-energy radiation pulses are applied to the toner image.
  • Short means a time period of less than 0.5 ms and “low-energy” means an energy of less than 0.5 J / cm 2 , with a pause preferably between two successive radiation pulses.
  • An exemplary embodiment of the method is furthermore preferred which is characterized by that the toner image melted so far in a first processing step is that there is a relatively high gloss, and that in a subsequent, second Processing step, the toner image with so much heat energy that at least Parts of the toner material, in particular the surface layer of the toner image, overheated and thereby deliberately damaged.
  • the toner material evaporated or there is an oxidation, which in both cases leads to a rougher Surface and thus leads to a reduced gloss.
  • the degree of damage to the The toner image surface can be influenced by various measures.
  • a The first possibility is a very thin, near-surface toner layer of the toner image to heat, which creates tensions in this toner layer that cause wrinkles or cause the toner image surface to ripple. This will make the surface uneven or rough, which leads to a reduction in the gloss.
  • a another option is to heat the entire toner image while the Image carrier substrate, which consists for example of paper, remains cold and possibly too is cooled for this purpose. Due to excessive heating of the toner material bubbles form in the toner image, which in turn is the surface roughness of the toner image let rise. With this variant for controlling the toner image gloss, it can be too a reduction in the color saturation level, with a targeted process control the influence on the color saturation level can be minimized.

  • the radiation device emits electromagnetic radiation and / or radiation pulses whose wavelength range is chosen so that they penetrate the shell of the roll, at least for the most part.
  • the clocked or continuous radiation is therefore not from the roll shell material absorbed, so that the roll is at least largely not heated.
  • the radiation warms up thus only the toner image lying on the outer surface of the roller.
  • the toner image is subjected to at least one radiation pulse which is shorter than the contact time between the roller and the toner image.
  • the energy of the radiation pulse preferably heats only the uppermost toner layer of the toner image, which thereby melts at least partially, so that the structure of the roll outer jacket is impressed.
