Description of drawings
Fig. 1 is the method flow diagram of area of trap preview in the embodiment of the invention;
Embodiment
Below in conjunction with Figure of description and embodiment, the present invention is described in detail.
A kind of system of area of trap preview comprises whole area of trap previewing module and color separation version area of trap previewing module, wherein:
Between trapping object and trapping layer, add white transparent preview layer when described whole area of trap previewing module is used for that whole area of trap carried out preview and whole area of trap is carried out preview;
Remove the look version of non-inspection printing ink look when described color separation version and the preview of special look area of trap are used for color separation version and special look area of trap preview, between trapping object and trapping layer, add white transparent preview layer and color separation version and special look area of trap and carry out preview.
In the present embodiment, be respectively equipped with the definition adjusting module in described whole area of trap previewing module and the color separation version area of trap previewing module, be used to adjust the definition of the white transparent preview layer that is added, concrete method of adjustment is to adjust the definition of the white transparent preview layer that is added by saturation or transparency.
A kind of method of area of trap preview in the embodiment of the invention comprises whole area of trap preview and the preview of color separation version area of trap, wherein:
The method of described whole area of trap preview is to add white transparent preview layer and whole area of trap is carried out preview between trapping object and trapping layer; The method of described color separation version and the preview of special look area of trap is to remove the look version of non-inspection printing ink look, adds white transparent preview layer between trapping object and trapping layer.
As shown in Figure 1, specifically may further comprise the steps:
Whole area of trap preview:
S11: add white transparent preview layer;
S12: whole area of trap preview.
Color separation version and the preview of special look area of trap:
S13: the look version of removing non-inspection printing ink look;
