A printing system and method for automatically generating printing bleed and cutting line

Abstract

The invention discloses a method for automatically generating printing bleeds and cutting lines, comprising the following steps: S1, obtaining a printed manuscript; S2, converting the printed manuscript into a bitmap manuscript, and generating the outline of the bitmap manuscript; S3, According to the set printing size, judge whether the bitmap document contains a bleed; if the bitmap document contains a bleed, shrink the contour line according to the set expansion parameters to generate a trim line; if the bitmap document does not contain a bleed, then Execute step S4; S4, expand the outline according to the set expansion parameters to generate a bleed area, and fill the bleed area with color and / or pattern to generate a bleed document, and the outline constitutes a trimming line of the bleed document ; S5, converting the bitmap manuscript containing the trimming line in S3 or the bleed-bit manuscript in S4 into a printed vector plate. Automatically generate bleeds to improve the quality of your prints.

Description

technical field [0001] The invention belongs to the technical field of printing industry, in particular to a printing system and method for automatically generating printing bleeds and cutting lines. Background technique [0002] The bleed refers to the convenient cutting part reserved for retaining the effective content of the screen during printing. Bleeding in printing refers to the pattern that increases the outer size of the product, and some pattern extensions are added at the cutting position, which is specially used for each production process within its process tolerance range, so as to avoid the white edge of the finished product after cutting or the content of the cut. . During production, we divide it into design size and finished product size. The design size is always larger than the finished product size. The larger side is cut off after printing. The part to be printed and cut off is called Bleeding or bleeding bits. [0003] Existing print bleeds are main...
