Method for implementing direct printing by associating logic and intelligent screening

Abstract

The present invention relates to a method which realizes direct printing via pseudo frequency modulation screening. According to the incidence relation between a pixel and the surrounding pixels, the method divides a monochrome in the original pixel into four new monochromic pixels by diagonal correlation, and according to different correlations, increases the transitional hierarchy or the contrast; then the gray value of the four new monochromic pixels is further embodied by the appropriately inking cells in 8 multiplied by 8 lattices by the method of correlative logic reasoning, finally quaternate appropriately inking cells are directly provided to a printing device, as a result, a lattice image which can better reflect the gray level distribution in comparison with the original pixel is obtained, the processing and the operational speeds are quicker, the used external devices can be cheaper, the occupied storage space is fewer, and meanwhile, under the same processing requirement, the precision, the acuteness and the transitional hierarchy of the lattice image are increased by multiple times.

Description

technical field [0001] The invention belongs to the category of printing technology, the main part of which is embodied in the form of computer software, and specifically relates to a method for realizing direct printing by intelligently screening according to the actual requirements and trends of graphics and characters through associative logic algorithms. Background technique [0002] The basis of modern printing is screening technology. As the core of screening technology, what kind of method is used to make continuous tones discrete into halftones. The traditional printing and plate-making process uses optical methods to achieve discrete processing of continuous tone screen operations. The method is based on color separation, using projection screens or contact screens to discretely tone grayscale images into a single However, the collection of black dot groups of different sizes finally achieves the purpose of printing such dots to reflect the continuous gray scale of ...

Problems solved by technology

The purpose of realizing half-screen dots is to finally realize printing through plate making, but the various requirements of plate making and printing greatly limit the smooth realization of half-screen dots. As a result, the realization process of half-screen dots becomes extremely complicated and complicated. Unpredictability, but that's it, it still can't adapt to various and changeable printing requirements, so the half-screen screen adjustment can't fully meet the actual requirements of specific printing equipment anyway.
