Dot raster pattern four-color overprinting offset correction printing process

Abstract

The invention relates to the technical field of raster and particularly relates to a dot raster pattern four-color overprinting offset correction printing process. During printing, by the ways of controlling arrangement of dot matrix plating pixel points, controlling offset extent of four-color printing pixel points and controlling the corresponding relationship between pixel matrix plating and dot raster and the like, a printed dot raster pattern has a deep space three-dimensional impression. The dot raster pattern four-color overprinting offset correction printing process disclosed by the invention cooperates with a dot-shaped lens array which is formed by a plurality of uniformly-arranged dot-shaped lenses on a dot raster plate and is orderly in rows and lines so as to perform dot matrix plating treatment, pixel matrix laying treatment and pixel matrix offset treatment on an image; by controlling the arrangement of the dot matrix plating pixel points, the offset extent of the four-color printing pixel points and the corresponding relationship between pixel matrix plating and dot raster, the printed dot raster pattern has a deep space three-dimensional impression.

Description

technical field [0001] The invention relates to the technical field of gratings, in particular to dot gratings Figure four Color overprint offset corrects the printing process. Background technique [0002] The lenticular three-dimensional picture is a three-dimensional changing effect of the pattern that can be felt by adjusting the angle. At present, gratings are divided into slit gratings, lenticular gratings, and dot gratings according to the lens form. The former two can only perceive the three-dimensional image through the linear offset angle perpendicular to the slits and lenticular lenses. images, prone to a certain degree of dizziness. [0003] The dot grating is a special optical material composed of countless neatly arranged spherical mirrors. Each dot is a miniature convex magnifying glass. By turning 360° from the grating surface, the grating surface perceived by the naked eye is the same. Compared with the slit grating and lenticular lens grating, it has th...

[0004] For the dot grating, generally by printing simple spatial sense graphics, and using the plane graphics without spatial sense as the spatial reference system, to deepen the visual spatial three-dimensional effect of the spatial sense graphics and form a sense of depth; In the process of printing the array pattern to the bottom surface of the lenticular plate or the bottom plate material, it needs to be overprinted by four-color printing. It is easy to cause the final product to have ripple-like or grid-like interference patterns due to pixel offset, which affects the visual effect
