  FIG. 1 shows a fine pattern forming apparatus. As shown in FIG. 1, the fine pattern forming apparatus 1 is configured so that an ink receiving surface of a metal flat plate 2 having flexibility is outward. A plurality of fixed plates arranged at regular intervals around the outer peripheral surface of the endless belt 3, which is a continuous body of screen-printed screens (印刷), so that each metal plate 2 is conveyed. The plate support section 4 and four bodies for transferring the pigment ink to the metallic flat plate for each of the constituent colors (K (black), Y (yellow), M (magenta), C (cyan)) of the fine pattern Printing units 5K, 5Y, 5M, and 5C, and a transfer means 7 that supports the printing body 6 made of a transparent plate or the like and transfers a fine pattern from the metallic flat plate 2 to the printing body 6. The printing unit 5K, 5Y, 5M, 5C is mounted It is arranged on a 8.

As shown in FIG. 1, in each of the printing units 5K, 5Y, 5M, and 5C corresponding to the four colors that are the constituent colors of the fine pattern, the slot-type coating head 9 that can apply the pigment ink of the constituent colors at a constant thickness, A first metal roller 10 serving as a first support member which receives a pigment ink applied from the slot type coating head 9 and supports a pigment ink layer described later, and the first metal roller 10 in contact with the first metal roller 10. A removal metal roller 11 that is a peeling member for removing unnecessary pigment ink as described later from above, and a second support member that supports the pigment ink by transferring the pigment ink in a printing pattern from above the first metal roller 10. The second metal roller 12 is used.
Each of the printing units 5K, 5Y, 5M, and 5C forms a printing pattern of a corresponding component color, and the printing pattern is transferred to the flat plate every time the flat plate 2 is moved by the plate movement of the printing plate support 4. The image is transferred onto the plate 2.
The printing units 5K, 5Y, 5M, and 5C that transfer the pigment ink to the flat plate 2 of the printing plate support 4 have the same configuration except that the pigment ink of the component color and the print pattern corresponding to the component color are different. For example, the operation of the printing unit 5K will be described. First, the pigment ink (K) of the constituent color is applied from the slot-type coating head 9 with the coating thickness constant, and the first metal roller 10 is not uneven. By supplying the solid portion, a pigment ink layer having a uniform film thickness is formed.
Further, the second metal roller 12 has a plate made of convex portions corresponding to the print pattern as shown in FIG. 3 so that a print pattern of a constituent color can be obtained on the peripheral surface. As shown in FIG. 4, the printing plate has a plate made of convex portions corresponding to the negative pattern of the printing pattern. Each of (a) in FIG. 3 and FIG. 4 shows a partial development of the plate, and the halftone dot display portion in the figure expresses the constituent color pigment ink, and the print pattern and its negative pattern are schematically shown. Although shown, the print pattern is not limited to the illustrated pattern.
The removal metal roller 11 and the second metal roller 12 rotate so that the removal metal roller 11 is in contact with the solid portion at the front position in the rotation direction of the first metal roller 10, and at the rear position. The two metal rollers 12 are rotating so as to be in contact with the solid portion, and the pigment ink is transferred from the solid portion of the first metal roller 10 to the removal metal roller 11 and the second metal roller 12.

First, in the portion where the first metal roller 10 and the removal metal roller 11 are in contact with each other, the convex part of the negative pattern (negative pattern plate) of the removal metal roller 11 is in contact with the thin film of the pigment ink layer, and the convex part is Half of the pigment ink in the thickness direction of the thin film is transferred to the convex portion of the removal metal roller 11 at the contacted portion. By this transfer, the pigment ink is peeled and removed from the surface of the thin film on the solid portion of the first metal roller 10 by the negative pattern of the printing pattern, and the pigment ink layer on the solid portion has a surface shape. Is formed as a concavo-convex thin film in which the portion corresponding to the printing pattern of the constituent color is raised.
And in the part which the said 1st metal roller 10 and the 2nd metal roller 12 contact, the convex part (plate of a printing pattern) of the 2nd metal roller 12 is a convex part of the position corresponding to the printing pattern in the said uneven | corrugated thin film. (Pigment portion of the pigment ink) is in contact with each other, and half of the contacted bulge portion in the thin film thickness direction is caused by the rotation of the first metal roller 10 and the second metal roller 12 so that the second metal roller 12 Transfer to the convex part. Thereafter, the thin film made of the pigment ink transferred to the convex portion of the second metal roller 12 is dried, and a printed pattern made of the thin film is obtained on the peripheral surface of the second metal roller 12. When the solvent from the pigment ink evaporates due to drying on the second metal roller 12, the thin film becomes semi-cured and has adhesiveness, and the peripheral surface of the second metal roller 12 is adhesive semi-cured. A thin film is formed in a printed pattern.

The film thickness of the adhesive semi-cured thin film by the pigment ink is measured by the film thickness meter 13, and the quality is judged, and only the non-defective product is transferred to the metal printing flat plate described later. The printing units 5Y, 5M, and 5C have the same configuration as the printing unit 5K, and are similarly provided so as to obtain an adhesive semi-cured thin film by pigment ink at the convex portions of the respective second metal rollers 12.
Each printing unit includes a collection roller 14 and a squeegee 15 for collecting the pigment ink from the removal metal roller 11. The second metal roller 12 is adjusted to 60 ± 0.5 ° C. in order to promote the drying of the pigment ink.

(Transfer to metal printing flat plate)
When the adhesive semi-cured thin film of the printing pattern is formed on the second metal roller 12 of the printing units 5K, 5Y, 5M, and 5C, and the film thickness reaches a set value, the end of the printing plate support unit 4 is endless. The belt 3 rotates to move the metal flat plate 2 onto the second metal roller 12 of the printing unit (for example, the printing unit 5K in the example shown in the figure) arranged at the head, and temporarily stops at the corresponding time. Then, the position of the printing pattern of the second metal roller 12 is aligned with the set position on the flat plate 2 where the printing pattern is to be positioned, and superposition is performed.
The superposition is performed by lowering the press cylinder 16 waiting above each printing unit with the flat plate 2 in between. For example, in the printing unit 5K, the press cylinder 16 and The plate 2 is sandwiched between the second metal roller 12 and the endless belt 3, and the press cylinder 16 and the second metal roller 12 are respectively sandwiched and rotated to move the second metal roller 12. The adhesive semi-cured thin film of the pattern is transferred to the flat plate 2. When the transfer of the first color is finished, the plate-like plate 2 is moved to the next printing unit side by the operation of the printing plate support section 4, and the above-mentioned transfer is performed in each printing unit, and the adhesive half of each printing pattern is transferred. A fine pattern formed by combining the cured thin films is formed on the flat plate 2.

The flat plate 2 on which the fine pattern is formed is conveyed and stopped above the X, Y, θ control surface plate 17 by the operation of the printing plate support 4. The X / Y / θ control surface plate 17 and a press peeling cylinder, which will be described later, constitute transfer means, and the position on the printing medium 6 arranged and fixed on the X / Y / θ control surface plate 17. Based on the alignment mark and the alignment mark of the flat plate 2, the position is adjusted on the X, Y, θ control surface plate 17 side so as to align the X, Y, θ control with the flat plate 2 in between. The X / Y / θ control surface plate 17 is lifted so as to be sandwiched between the press peeling cylinder 18 waiting on the surface of the surface plate 17.
Then, the press peeling cylinder 18 moves along one side direction of the flat plate 2 and presses the flat plate 2 against the printing body 6 on the X, Y, θ control surface plate 17 to bring it into close contact therewith. In addition, when the to-be-printed body 6 is a transparent board, you may make it perform exposure by ultraviolet irradiation from the downward direction of this to-be-printed body after this contact | adherence.

  After the adhesion (after exposure when there is exposure by ultraviolet irradiation), the press peeling that lifts the end of the printing plate support 4 on the transfer means side by about 5 cm and leaves the raised end By the rotational movement of the cylinder 18, the flat plate 2 is peeled off from the printing medium 6 from the rear side in the moving direction of the press peeling cylinder 18, and the fine pattern is transferred to the transparent substrate 6 to be completed. Every time the fine pattern is transferred to the printing medium 6 and completed, the above process is performed by replacing the printing medium 6.

  As described above, when forming the fine pattern, the adhesive semi-cured thin film formed as a printing pattern for each constituent color from the printing units SK, 5Y, 5M, and 5C is transferred to the flat plate 2 and the respective adhesive properties are transferred. After forming a fine pattern composed of semi-cured thin films on the flat plate 2, multi-color printing is performed in which the fine pattern is transferred from the flat plate 2 to the substrate 6 at one time. Thus, the printed material 6 on which a fine fine pattern is printed is obtained.

When the substrate 6 is transparent, the surface plate on which the substrate 6 of the X / Y / θ control surface plate 17 is placed is made of quartz glass, so that it can transmit ultraviolet rays well. The fixability of the ink to the printing medium 6 can be further improved.
When transferring the pigment ink (adhesive semi-cured thin film) from the second metal roller 12 to the flat plate 2, the transfer time between the press cylinder 16 and the second metal roller 12 is about 30 seconds. If the transfer time can be ensured, the printing medium 6 can be sufficiently replaced on the X / Y / θ control surface plate.
The transition time in which the alignment and sandwiching of the pattern by the flat plate 2 and the printing medium 6 is good is about 30 seconds. During this time, the endless belt 3 is stopped and formed on the second metal roller 12. The printed pattern can be sufficiently dried.
The printed material is a hard plate such as a glass plate, a plastic plate, or a metal plate, or paper, a plastic film, a metal film, or the like, and can form a fine pattern.

  The surfaces of the second metal rollers 12 of the printing units 5K, 5Y, 5M, and 5C are covered with a resin film of polyvinyl alcohol. The fixability in the wet state of the pigment inks (both four colors of KYMC) used for this fine pattern decreases as the solvent evaporates and becomes a semi-cured state. Is generated and transfer is facilitated. In particular, when the resin thin film covers the second metal roller, the pigment ink is easily fixed due to the relationship between the solvent component of the pigment ink in the wet state and the constituent material of the resin thin film, and the solvent component is reduced by drying. The relationship with the constituent material of the resin thin film for fixing is cut off, so that the pigment ink is easily peeled off. As described above, the second metal roller 12 is provided so as to improve the fixability of the wet pigment ink layer and to transfer the adhesive semi-cured thin film to the flat plate.

The above embodiment is a combination of print patterns in which a fine pattern is a desired pattern, but the following changes combine the print patterns in which the pixel pitch and the like are defined in advance to obtain a color filter. A color filter for liquid crystal display can be formed.
First, the color of the color filter for the liquid crystal display is different from K, Y, M, and C in the above embodiment, and R, G, and B pigment inks are used. In the liquid crystal display color filter manufacturing apparatus, A printing unit is provided for each of the R, G, and B constituent colors. Then, as in the above embodiment, the plate-like plate is conveyed by the printing plate support portion in which a plurality of plate-like plates are arranged with the ink receiving surface outward on the continuum, and the plate-like plate is fed out. The adhesive semi-cured film formed as a printing pattern of the constituent color is transferred from the printing unit for each constituent color of R, G, and B, and the color filter pattern is formed on the flat plate by combining the adhesive semi-cured thin films. Then, the color filter pattern is transferred from the flat plate to a substrate to be printed (a transparent plate such as a glass plate for a filter). The black matrix itself can be provided in advance on the substrate or after the pattern is transferred, and a printing unit for transferring the black matrix pattern to the flat plate can be used as the R, G, B printing unit. It is also possible to arrange them side by side.
Of course, the first metal roller in the printing unit for each component color is a solid plate, the removal metal roller is provided with a convex plate that forms a negative pattern of the print pattern corresponding to the component color, and the second metal roller is a component color. A printing plate corresponding to the printing pattern is provided, and each printing pattern is a pattern set in advance for constituting a color filter. The point that the surface of the second metal roller can be covered with a resin thin film, and the point that the flat plate can be made of a flexible metal are the same as in the above embodiment.
By the above-described color filter manufacturing apparatus for liquid crystal display, the printing pattern of each constituent color in the color filter pattern is reliably transferred to the flat plate, and the respective printing patterns having a uniform film thickness on the flat plate are combined. A color filter pattern can be formed. Since the color filter pattern is transferred from the flat plate that is sequentially sent out in the possession of the color filter pattern to the transparent plate that is the printing medium, high-quality printing is achieved by multicolor printing with no misalignment between the printing patterns. A color filter can be formed continuously.
