Description

  Silver coated paper for printing {coated watermark paper for printing}

The present invention uses organic and inorganic materials such as clay, heavy calcium carbonate, hard calcium carbonate, titanium dioxide, talc, adhesives such as starch, casein, latex, and other additives on the silver paper produced in the papermaking process. The present invention relates to the production of silver coated paper coated with a coating solution (coating solution) made by using an air knife, a rod and a blade coating machine.

The silver coated paper is not only printable when the silver paper made by the existing paper machine is printed on various printing presses, but also when the multicolor printing of various colors is made, the print quality is poor and the desired printed image can be obtained. none. In the present invention, by coating on a silver paper with various raw materials and methods (coating) to produce a silver coated paper for printing, it is not only easy to determine whether the paper made after printing is the original, but also to increase the value by giving aesthetics There is this.

As a coating solution of silver paper, organic and inorganic pigments, various adhesives and additives are prepared at a solid content of 10 to 80%. The coating solution prepared in this way is coated with a small amount of coating through a size press process present in various types of coating machines, air knifes, rolls, rods, blade coating machines, and paper machines for producing silver paper. It is made by doing.

The silver coated paper is printed through the printing process such as flat plate, convex plate, and intaglio, and silver is appeared when light or electric light source is reflected on the other side of paper after printing. Not only can it be easily identified, it also gives an aesthetic effect.

In order to manufacture the silver paper, silver is given to the web surrounding the dandy roll of a cylinder mold or a long paper machine to make a silver paper. Phosphor bronze mesh or stainless steel mesh is used to wrap the dandy roll of cylinder mold or long paper machine, and in order to give silver to this mesh, phosphor bronze such as intaglio, emboss, sculpture and streaks A silver net is manufactured that can be attached to a cylinder mold or a dandy roll to be mounted on a long paper machine by being pressed into a net or stainless steel net. Silver paper is made when paper is produced in paper machine using the attached silver net.

Coated paper is coated with clay, talc, heavy calcium carbonate, hard calcium carbonate, titanium dioxide and various organic and inorganic materials through various methods on plain paper for more accurate printed images and mass printing. Starch, casein and A coating liquid with a concentration of 10% to 80% is mixed by mixing an adhesive and an additive. When coating the coating liquid using a coating machine such as a roll, a rod, a blade, or an air knife, etc. Coated paper will be made. At this time, coating (Coating) is made of one side coating (Coating) only one side, both sides coating (Coating) coating on both sides (Coating) is made, each coating (Coating) is a coating of single and multiple layers on each side Can be made of layers.

There are two methods for producing silver paper, one using a cylinder mold and one using a dandy roll of a long paper. The type of silver coin has a desired thimble or letters. However, the silver paper thus produced is not suitable as a large quantity of printing paper, and thus has problems in obtaining various print qualities. Therefore, in the present invention, not only the printing property is improved by coating by using various types of coating machines and methods on the silver sheet. The printing and security of silver coated paper gave security and aesthetics.

Manufacture of silver coated paper by coating silver on paper sheet system using cylinder molder and long sheet paper system using dandy roll.
