Abstract

PROBLEM TO BE SOLVED: To print directly without the use of a blanket roller by forming a metal film on a cushion layer formed of rubber, forming ink receiving cells on the surface layer part of the metal film, and forming chromium plating to give plate wear resistance force on the surface of the metal film having the cells. SOLUTION: An intaglio plate having a cushion property is formed by winding and adhering a cushion layer 2 of urethane rubber or silicone rubber, forming copper plating by electroless plating, and forming copper plating 3 by electroplating on the surface of an aluminum plate base material 1 ground precisely into a circular or cylindrical shape in its outer surface. Subsequently, it is ground smoothly, and further subjected to specular grinding, and next the surface is activation-treated to coat and dry the photosensitive film uniformly and print images directly by a laser exposure device, or superimpose and expose the film to print images to then be subjected to developing and etching operation before defining cells 4 on the surface layer and, in the next place, a chromium plating 5 is applied on the surface of the copper plating 3 having cells 4 after resist-peeling to give plate wear resistance force.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an intaglio plate having a cushioning property suitable for color printing of a matrix image for forming a color filter on a glass for a liquid crystal panel or color printing of an image on a compact disk or the like. About.

[0002]

2. Description of the Related Art Conventionally, gravure offset printing or waterless offset printing has been employed for color printing of a matrix image for forming a color filter on a glass for a liquid crystal panel or color printing of an image on a compact disk or the like. And gravure printing has not been adopted. The reason is that if the printing pressure increases, the glass will be broken, so by printing via a blanket roll made of rubber, when the printing pressure increases, the gravure offset printing can suppress the printing pressure increase due to the deformation of the rubber when the printing pressure increases Is appropriate.

[0003]

However, in gravure offset printing, when transferring ink from a blanket roll to a printing material such as glass, it is impossible to perform printing with zero printing pressure. Is applied to the substrate under pressure, and the outline of the ink spreads out or is disturbed, which is one of the reasons why the value of line and space cannot be reduced, and high-definition printing is required. The color printing of a matrix image for forming a color filter on the glass for a liquid crystal panel to be performed is considerably inferior in quality to the production of a color filter by a film method. In the production of color filters by printing, the waterless planographic intaglio offset method is adopted, but the sharpness of the image is low, the edge of the line image is disordered,
The line image had irregularities.

The present invention has been made in view of the above points, and can directly print on a hard printing material without using a blanket roll. In particular, a color filter is formed on glass for a liquid crystal panel. It is an object of the present invention to provide an intaglio having a cushioning property suitable for color printing of a matrix image or color printing of an image on a compact disc or the like.

[0005]

According to a first aspect of the present invention, a metal film is formed on a cushion layer made of rubber, and a cell for containing ink is formed on a surface layer of the metal film. An object of the present invention is to provide an intaglio having a cushioning property, which is formed by forming chromium plating for imparting printing durability on the surface of a metal film. The second invention of the present application is, on the surface of the roll-shaped plate substrate, a cushion layer made of rubber having a uniform thickness and a high degree of smoothness is wound and adhered so that no gap is opened at the seam, and by electroless plating, After forming a plating film from the end surface of the plate base material to the surface of the cushion layer, an electroplating film is formed, the surface of the electroplating film is cylindrically polished, mirror-polished, coated with a photosensitive film, and an image is printed,
It is intended to provide an intaglio having a cushioning property, characterized in that cells are formed by developing and etching and coated with chromium plating.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An intaglio having cushioning properties according to an embodiment of the present invention will be described with reference to the drawings. In FIG. 1, (a) is a cross-sectional view showing a roll-shaped intaglio at a stage where a metal film is formed, (b) is an enlarged cross-sectional view showing a state in which cells are formed on a metal film, and (c) is a cell formed. FIG. 7 is a partially enlarged cross-sectional view showing a state in which a chrome-plated metal film is completed as an intaglio. Reference numeral 1 is a plate base, reference numeral 2
Denotes a cushion layer 2, reference numeral 3 denotes a metal film, reference numeral 4 denotes a cell, and reference numeral 5 denotes a chromium plating film. This intaglio having cushioning properties is a hollow shape having holes to be chucked at both ends, and a smooth surface of a plate substrate 1 made of aluminum (or may be made of iron) whose outer surface is precisely polished to a perfect circle and a cylinder is provided with 5 to 5 10cm
A cushion layer 2 made of urethane rubber or silicon rubber having a uniform thickness and a high degree of surface smoothness is wound and bonded so that no gap is opened at the seam, and chuck holes at both ends of the plate substrate 1 are chucked. And immersed in an electroless plating solution and rotated, so that copper plating can be performed by electroless plating from the end surface of the plate substrate 1 to the surface of the cushion layer 2.
Then, the plate substrate 1 is immersed in an electrolytic copper plating solution, rotated, and a plating current is applied to the plate substrate 1 to form a copper plating 3 by electroplating.
A film having a thickness of 0 μm is formed, then the surface of the copper plating 3 is polished smoothly by a grindstone polishing device and further mirror-polished, and then the surface of the copper plating 3 is subjected to a surface activation treatment and then exposed to light. The film is uniformly coated and dried, and the image is directly printed by a laser exposure device or the image is printed by overlapping and exposing the film, and then developed and etched, so that the surface layer of the copper plating 3 is formed. , 5-2
A cell 4 (a gravure cell or a pattern cell for a color filter) for accommodating the ink is formed so as to have a depth of 0 μm, the resist is peeled off, and then the printing resistance is applied to the surface of the copper plating 3 having the cell 4. It is coated with chrome plating 5 to be applied. The intaglio having cushioning properties of the first invention of the present application includes not only a roll plate but also a planographic plate.

[0007]

As described above, according to the intaglio having cushioning properties of the present invention, it is possible to print directly on a hard printing material without using a blanket roll. Therefore, unlike gravure offset printing, ink transfer can be guaranteed without ink being crushed by printing pressure, so that the sharpness of the image is high, and the disturbance of the edge of the line image and the unevenness of the line image are reduced. . By using UV ink as the ink and applying a technique of irradiating a UV light source to the ink placed on the plate cells to make it semi-dry and then transferring it, a matrix image for forming a color filter on the glass for liquid crystal panels can be obtained. It is suitable for color printing or color printing of an image on a compact disc or the like. If a color filter of the same quality as a color filter manufactured by the film method can be manufactured by the printing method, the manufacturing cost of the color filter can be drastically reduced as compared with the film method. is there.
