Problems solved by technology

The existing technology uses manual revision, which not only consumes a lot of man-hours, but also causes pattern distortion to a certain extent. From the perspective of printing effect, the copied pattern can only reflect the similar color of the main color of the original manuscript, and cannot fully reflect the color of the original manuscript. color, so that the restoration quality cannot be guaranteed

Embodiment Construction

[0006] The present invention will be further described below in conjunction with embodiment.

[0007] First, briefly introduce the types and functions of electronic color separation machines. Electronic color separation machines are mainly divided into dot type electronic color separation machines and continuous tone electronic color separation machines. The former is generally used in offset printing methods to scan originals and output various color separation films corresponding to the originals. On the film Record various color separations with the density of dots. The various color separation films output by the latter after scanning the original are continuous tone films without dots, and its key parts include scanning rollers and photosensitive rollers. When used, the original is fixed on the scanning roller and the film is installed on the photosensitive roller. In the scanning process, the induction of various color separations is converted into analog electrical sig...

Abstract

A collotype printing method includes taking up image, using electronic colour separator to separate it to become 4 colour-separation negatives, making their plates and printing with the inks with relative colours. Its advantages are high colour-separating speed and accuracy, less number of plates, and low cost.

Description

technical field [0001] The invention relates to a printing method, in particular to a collotype printing method. Background technique [0002] The collotype printing method is a traditional printing process. This method transfers ink films of different thicknesses to the surface of the substrate through the printing plate to form a continuous-tone non-screen printing pattern, which can truly reflect the layers and textures of the original. It is widely used to copy calligraphy and painting works of art. Using the collotype printing method to reproduce color manuscripts requires a rather complicated process. First, the manuscript must be photographed and color-separated. Pick it out and keep a color sample. Then, on the basis of photographic color separation, shoot multiple films, and then use manual editing to retain the image of the spot color area and cover the images of other areas to repair the negatives of each spot color. Under normal circumstances, it is necessary t...
