Embodiment Construction

[0043] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0044] The invention provides a printing bottom laying device, which mainly includes the following modules:

[0045] Color block generation module: used for color block processing of all objects on the layout to generate color blocks, and to mark the color block type;

[0046] Bottom contour generation module: used to obtain the overall contour of adjacent color blocks according to the above-mentioned generated color blocks, and shrink back to obtain the bottom contour;

[0047] Pavement contour correction module: used to correct the pavement contour when there are adjacent thin line objects in the pavement contour;

[0048] Pavement graphic block generation module: used to merge the corrected pavement outline with the color-blocked graphic outline to generate a new pavement graphic block;

[0049] Base color filling module: used to fill the ...

Abstract

The invention relates to a printing bottoming method and a device adopting the same, which belong to the publishing and printing technical field. In the invention, a layout object is block-colored, the integral profile of the layout object is calculated, the block-colored layout object is contracted, a bottoming profile is corrected according to an adjacent fine line, the corrected bottoming profile and a color-blocked graph profile are combined to form a novel bottoming graph block serving a bottoming color filling area, the gradation property of the original block is reserved, and eventually, bottoming color filling is conducted to the bottoming graph block according to the type of the color block. By adopting the method and the device which are provided by the invention, the bottoming profile of the fine line can be corrected, and gradation color filling of the bottoming graph block is realized, the printing pattern quality on a transparent printing medium or a printing medium withpatterns is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of publishing and printing, and in particular relates to a method and device for laying a printing base. Background technique [0002] In printing production, especially in the printing of packaging materials, when the printing materials are transparent media, such as plastic bottles, metal, gold cardboard, etc., if they are directly printed on these materials, the color of the printed matter will be unsaturated and look dull. Gray; or under the printing material with existing patterns, in order to retain the "bleed-through" effect of the pattern on the original material and avoid overprint confusion with the new printed pattern, in this case, it is generally necessary to add Print a layer of ink, this layer of ink is called backing, in order to prevent color overprinting from causing discoloration of the printed color. The base ink generally adopts white ink, or an ink that is close to white. [0003] The...
