Arrangement of color sequence during printing

In roll material gravure printing, the registration between different colors depends on the drum's linear speed and the amount of tension. In theory, the diameter of all platens should be exactly the same, and it is entirely possible to use a modern polishing device. If the diameter of the plate cylinder is deviated, the operator should place the plate with the smallest diameter in the first color group, and the plate with the largest diameter should be placed in the last color group. That is to say, the first color is printed first with a roller having the smallest diameter, and the last color is printed with the roller having the largest diameter, and the two are arranged in ascending order. It should be noted that the error we are talking about here is an error of a few thousandths of an inch.

The printing color sequence used for surface printing is generally from light to dark, that is, according to the order of the colors from light to dark, the printing color sequence is arranged, the light color is printed first, and then the printing is dark color, basically yellow (Y)è magenta ( M)è Cyan (C)è Black (K) order. In the printing process, the color sequence of the printing is the opposite. The dark color is printed first and then the light color is printed. That is, black (C) è magenta (M) è yellow (Y).
