Control the increase and decrease of printing dot in gift box printing
When printing screen pictures on the gift box, in order to ensure the product quality, we must make the dot get enough ink, and try not to enlarge (or shrink) the dot on the premise of making the dot solid, round and full. For this purpose, it is necessary to strictly check whether the dot on the printing plate conforms to the original version and the original sample, and whether the dot on the printing sheet conforms to the printing plate, and the increase and decrease of the network point should be controlled in a small amount.
Because the task of offset printing process is to make the various color plate patterns superimposed on the paper with color ink, and the commonly used comparison basis is the proofing machine printed sample sheet. To make the printing sample in line with proofing, it is necessary to master the degree of dot enlargement and reduction within the allowable range of color change.
