Embodiment 1

[0045] An interactive trapping method, see figure 2 , the interactive trapping method mainly includes the following steps:

[0046] S1, analyzing the artwork, obtaining all the color blocks in the artwork and the boundaries of each color block;

[0047] Specifically, for the original artwork, interactive trapping data analysis is firstly performed, mainly to analyze the artwork to obtain all color blocks and color block boundaries in the artwork, and the subsequent operation object is the color block boundaries. All boundary states are set to initial states, such as image 3 Color blocks A, B, C and color block boundaries 1, 2, 3, 4, 5, 6 described in .

[0048] S2, capture the user's mouse drag operation, and identify the boundary of the target color block and the trapping direction from the mouse drag operation.

[0049] As an embodiment, the capturing the user's mouse drag operation and identifying the target color block boundary and trapping direction from the mouse dr...

Embodiment 2

[0064] An interactive trapping method, see Figure 8 , the interactive trapping method includes: firstly, analyzing the original artwork to obtain all color blocks and all color block boundaries in the artwork; setting basic trapping parameters; the user performs a mouse dragging operation: find the target color Block boundary, drag a line on both sides of the color block boundary according to your own intention. The starting point of the line is the From of the trap, and the end point of the line is the To of the trap. The direction of the trap can be indicated according to the starting point and end point of the line.

[0065] According to the user's mouse drag operation, the system kernel recognizes the boundary of the color block that needs to be trapped and the direction of the trap. When trapping the target color block, judge whether the adjacent color block boundary of the target color block boundary has participated in trapping, if so, merge the target color block boun...

Embodiment 3

[0067] An interactive trapping system, see Figure 9 , the interactive trapping system includes an acquisition module 101 , an identification module 102 and a merge generation module 103 .

[0068] Among them, the acquisition module 101 is used to analyze the artwork, and acquires all the color blocks and the boundaries of each color block in the artwork; the identification module 102 is used to capture the user's mouse drag operation, and identify Go out target color block boundary and trap printing direction; Combine generation module 103, be used to find the adjacent color block boundary of described target color block boundary, judge whether described adjacent color block boundary completes trapping, if so, then described The boundary of the target color block and the border of adjacent color blocks are merged to regenerate the trapping area; traverse all the traps of the borders of the color blocks that need to be processed in the artwork.

[0069] It can be understood t...

Abstract

The invention provides an interactive trapping method and system, and the method comprises the steps: analyzing a draft, and obtaining all color blocks in the draft and the boundary of each color block; capturing a mouse dragging operation of a user, and identifying a target color block boundary and a trapping direction from the mouse dragging operation; finding out a color block boundary adjacent to the target color block boundary, judging whether the adjacent color block boundary completes trapping or not, and if yes, merging the target color block boundary and the adjacent color block boundary to uniformly regenerate a trapping area; trapping of boundaries of all color blocks needing to be processed in the draft is traversed. Compared with a traditional trapping scheme, the interactive trapping scheme provided by the invention is easier to use, the connection between trapping areas is very good, and meanwhile, the efficiency is very high.

Description

technical field [0001] The present invention relates to the field of printing, more specifically, to an interactive trapping method and system. Background technique [0002] In the printing process, misregistration often occurs during multi-color overprinting. Overprinting is the printing that is carried out when the corresponding area of ​​the previous color plate is knocked out (Knockout), so overprinting is prone to inaccurate situations. Due to inaccurate overprinting, some small gaps will appear at the border of two adjacent color blocks, which is very unsightly. In order to avoid the occurrence of white leakage, it is necessary to generate some small overprint areas (trapping areas) between the edges of different objects, so that the human eyes cannot detect these white leakage. The above process is called trapping. [0003] The current trapping process is basically divided into two situations: 1, manual processing; 2, automatic trapping. in: [0004] 1. Manual pro...
