Catalog Printing China - How to prevent from ink layer and hair flower phenomenon?

In order to overcome the uneven layout of the ink layer, hair flower phenomenon, and due to lack of experience in the process, some printing factory often blindly increase the amount of ink to meet the bright and thick visual effect of printing ink layer, so that the printing ink layer over the bottom, imprinting and ink film crystallization and other adverse consequences. It must pay attention.

How to slove this problem? Especially for the catalog printing china, beacause there are many product photos:

1. Paper smoothness lead to ink layer hair

Paper rough absorption of ink is large, when the surface of the printing paper smooth, ink layer is prone to hairspray.

Solutions:

In this case, the appropriate increase in the printing pressure, so that the smoothness of the paper and printing ink layer, to achieve a uniform, adequate embossing contact conditions, so as to achieve a better printing ink layer to eliminate the phenomenon of printing ink layer, to ensure that the printing ink layer uniform and flat.

2. Printing pressure is weak resulting in ink layer

Wood base itself is not strong enough, the possibility of compression deformation, resulting in the printing pressure instability, the printing ink layer on the layout can not be evenly transferred to the printing sheet, this situation is often easy to make people mistakenly means that the ink supply is insufficient. On the other hand, because wooden bottom tray flatness is poor, can not meet the layout of normal ink and ink transfer.

Solutions:

The best way, in addition to the good pad plate operation technology, for printing a larger area of the plate, such as the format of more than 16, it is appropriate to use a good flatness and solid gold plate holder, can better prevent the page ink hair phenomenon.

3. Ink cloth ink balanc lead ink layer hair

Color printing is usually some large, ink absorption of multi-color overprinter products, and large printing to get even and appropriate ink coating, cots hard, can not achieve uniform transfer of ink and cloth ink, because cots hard its viscosity is weak, is not conducive to transfer ink.

Solutions:

Should carry on the careful analysis and the inspection one by one, discovers the mediation bad has the gap, should readjust to eliminate the gap. The clearance caused by wear of shaft head and shaft hole should be repaired. Such ability better avoid pass ink, cloth, ink balance caused by the product layout hair phenomenon.
