Abstract

PURPOSE:To facilitate printing having no bubblelike defect by a method wherein printing image grooves are formed on the surface part having good ink transferring properties of an intaglio blanket and the inked intaglio blanket into contact by the predetermined printing pressure with matter to be printed so as to press out ink. CONSTITUTION:An intaglio blanketl is constituted by arranging supporting member made of aluminum or the like as the lowermost layer and elastic stock made of silicone rubber or the like having good ink transferring properties as the main body part, on which printing image grooves 11 are formed so as to have the desired pattern. After ink 2 is supplied with a dispenser or the like to the intaglio blanket 1, which is wound round an impression on cylinder, the intaglio blanket 1 under rotation is brought into contact by the predetermined printing pressure with matter to be printed 3 such as glass substrate or the like. Thus, ink 21 is pressed out in the environs and removed. After that, by separating the intaglio blanket 1 from the matter to be printed 3, the ink in the printing image grooves 11 is transferred to the surface of the matter to be printed 3 so as to complete printing.

2. Description of the Related Art Conventionally, intaglio printing has been widely used for forming patterns on various components as described above. The main reason intaglio printing is adopted for such applications is that the transfer shape of the pattern, that is, the peripheral shape, anti-rattleness, film thickness uniformity, and other printing methods, such as letterpress printing and lithographic printing, It is superior to stencil printing method, screen printing method and gravure printing method.

For this reason, printing that requires precise pattern formation, for example, those requiring a high degree of matching with the original dimensions,
There is a high degree of matching requirement at the total pitch, a part and the whole surface must match the original plate uniformly, a line width must match the original plate, and the line width variation must be small. It is widely used in the production of products such as those that do not cause chattering in the image lines and those that require a uniform thickness of ink or resist film.

However, even in the intaglio printing method having the above-mentioned various features, it is necessary to finish the film thickness of the ink or the resist to be formed more uniformly in order to cope with the improvement of the required accuracy which has been increasingly strengthened in recent years.

That is, since the ink layer and the resist layer formed on the glass substrate or the like have different heights, the amount of light transmission is different, so that the peripheral portion can be seen as a thin see-through or the color is strong. The height is preferably as constant as possible, for example, as the image line 4a shown in FIG.

However, in the conventional intaglio printing method,
The formed ink layer or resist layer is not necessarily formed to have a constant height when observed in detail, and for example, it is not uniform as illustrated in (b), (c) and (d) of FIG. It was often printed in various shapes.

An image line 4b having a laterally non-uniform cross-sectional shape shown in FIG. 2 (b) corresponds to the direction in which the image line groove 51 of the intaglio printing plate 5 is formed as shown in FIG. 3 (a). This is an example when printing is performed by doctoring in the orthogonal direction, and the ink 2 in the image groove 51 is moved in the doctoring direction due to the affinity with the doctor 6 traveling from the left side of the drawing to the right direction and the viscosity of the ink itself. This is because the ink 2 was pulled, and the thickness of the ink 2 at the right end was larger than at the left end in the drawing, and as a result, the ink 2 was used for printing with an uneven cross-sectional state.

Reference numeral 20 in the drawing indicates a position where the ink 2 is separated into a blanket side and a printing intaglio 5 side when a blanket (not shown) is brought into contact with the printing intaglio 5 with a predetermined pressure and then separated. The ink 2 on the breaking line 30 is transferred to the blanket side and then transferred to a glass substrate or the like to form an image line.

An image line 4c having a cross-sectional shape shown in FIG. 2C is printed with the ink 2 filled in the image line groove 51 of the intaglio printing plate 5 as shown in FIG. 3B. This is an example of when the width of the drawing groove 51 is large, and the printing is likely to occur when the drawing groove 51 is printed as the drawing line 4c with a depressed center.

The image line 4d having the cross-sectional shape shown in FIG. 2D is doctored in the direction of forming the image groove 51 of the printing intaglio 5, and the ink 2 as shown in FIG. 3C. Is an example of the case of being filled and printed. Although not shown in this figure, there is a problem that the width and height continuously change in the longitudinal direction.

There is also a problem that bubbles are generated in the drawing line. The cause of the bubbles is, for example, when the blanket 1a is brought into contact with a predetermined pressure as shown in FIG. 4A in the doctored state as shown in FIG. Air is trapped between the blanket 1a and the blanket 1a, and when the bubble 7 is separated from the printing intaglio 5 and the blanket 1a, the bubble 7 is internally present as shown in FIG. 4B. Since the ink 2 is transferred to the blanket 1a side in this state, when the ink 2 in this state is transferred onto the printing object 3 such as a glass substrate, bubbles are generated inside the image line 4e as shown in FIG. 4C. 7 may be trapped or bubble marks 71 may be formed on the top.

When a transmissive display is formed by the above method, the light is refracted, the density of the coloring material is insufficient, and it becomes a serious defect such as unevenness, and when it occurs at the end, the image line 4e is flickered.
When it is used as a resist, defects such as breakage of the resist and lack of resistance occur.

[Function] When the inked intaglio blanket that has been inked comes into contact with an object to be printed such as a glass substrate with a predetermined printing pressure, the main body of the intaglio blanket is made of an elastic material, and the surface portion in which the image groove is formed is excellent. Because of the ink releasability, the flat surface of the printing material and the non-image area of the intaglio blanket are in close contact with each other, and the ink cannot be present in this close contact area, so the ink is extruded.

When the ink is pushed out from the contact portion between the surface of the material to be printed and the non-image area of the intaglio blanket, a force for pressing the ink into the image groove of the intaglio blanket acts, so that the image groove There are no gaps where the ink fills and bubbles are created. Then, after the excess ink pushed out is removed, when the intaglio blanket and the printing object are separated from each other, only the ink contained in the image groove is transferred and remains on the printing object, and a predetermined pattern is printed. Is done.

Therefore, when the intaglio blanket 1 is separated from the material to be printed 3 after the excess ink 21 extruded to the peripheral portion is removed by a suitable means such as a whisk, only the ink 2 contained in the image groove 11 is removed. Is transferred to the printed material 3 side and remains, and the image lines 4 are formed by printing in the pattern of the image line grooves 11 formed on the intaglio blanket 1.

In addition, since the surface of the intaglio blanket 1 is formed with good ink releasability as described above, the entire amount of the ink 2 contained in the image groove 11 is transferred to the side of the material 3 to be printed. Therefore, the image lines 4 formed on the substrate 3 are formed so as to completely correspond to the depths of the image line grooves 11, so that a uniform height can be obtained as long as the image line grooves 11 have a constant depth. Since the image line 4 is easily printed and formed, and there is no concern that air bubbles or bubble marks will remain, and also that ink rupture marks will not occur, the image line 4 will be printed neatly and chattering will occur on the outer peripheral line.
