Multi-positioning printing method for paperboard color printing

Abstract

The invention provides a multi-positioning printing method for paperboard color printing. The multi-positioning printing method comprises the following steps that in the multi-color register printingprocess, when a printing pattern of a single pattern layer is printed, a plurality of positioning lines are printed outside the printing pattern at the same time, and the positioning lines printed inthe previous printing step are taken as benchmarks for positioning in the later printing step. According to the method, the positioning line of each pattern layer can be printed simultaneously when the pattern layer is printed, the positioning lines printed in the previous printing step are taken as the benchmarks for positioning during printing of the later pattern layer, only errors caused by positioning of the positioning lines in the printing process exist, the errors cannot be accumulated in the later printing process, in this way, compared with a positioning mode that all the pattern layers in an original printing mode take one positioning line as a benchmark, error accumulation is avoided, the printing precision is improved, the edges of printed patterns are clear, lines are clear,and colors are more gorgeous.

Description

technical field [0001] The invention relates to the technical field of cardboard printing, in particular to a multi-position printing method for color printing of cardboard. Background technique [0002] At present, most of the products sold on the market need to be packaged in packaging boxes. In order to look beautiful and show product features, the current packaging boxes will be spliced ​​with colored cardboard. The existing cardboard printing is divided into spot color printing and four-color printing. , spot color printing refers to the printing process of replicating primary colors with inks of other colors than yellow, magenta, blue, and black. In packaging printing, spot color printing is often used to print large-area background colors. Four-color printing is to print a color picture through the three subtractive primary colors (yellow, magenta, and cyan) and black, the primary color image used for printing must be separated into its own color separator, and a blac...
