Abstract

The invention provides a method for making a high-definition high-fidelity color picture of TPW 10 mu m on a surface of paper. The method comprises the following steps of: inputting a pattern of original color picture to be made into a computer through USM scanning of an electronic color scanner and synthesizing a 1,200 dpi TIF electronic file picture; toning and optimizing the electronic file picture by using color management software; performing color separation on three primary colors of the electronic file picture into seven channels, namely Cyan, Magenta, Yellow, Black, Orange, Green and Blue, by using GSM 2.0 software; maximizing the coverage of various colors in a chromatogram; transferring and outputting the processed electronic file picture to a PS printing plate by using sensitization; and finally transferring the pattern to the paper by using a planographic press. The image made by the method has high definition and rich hierarchy and represents the natural color of the original picture and the vivid color gamut.

Description

Make the method for TPW10 μ m fine definition, high-fidelity colour picture at paper surface

Technical field

The present invention relates to paper surface and make the method for colour picture, relate in particular to a kind of method of making TPW (modulating net) 10 μ m fine definition, high-fidelity colour picture at paper surface.

Background technology

In the prior art, by scanner technology photo is translated into electronics shelves photo, become Cyan, Magenta, Yellow, Black to transfer on the positive film or the pre-coating light sensitive plate color separation of electronics shelves photo again, again by printing machine with cyan ink, the last magenta ink of M, the last Yellow ink of Y, the last black ink pattern transfer of K on the C version to paper.

Said method exists that pattern is careful inadequately, the tone light and shade change indeterminate, picture is flat, level is outstanding, the not high deficiency of definition, can't show the nature realistic colour.

Summary of the invention

The objective of the invention is to overcome the deficiency that prior art exists, a kind of method of making TPW 10 μ m fine definition, high-fidelity colour picture at paper surface is provided.

Purpose of the present invention is achieved through the following technical solutions:

Method in that paper surface is made TPW (modulating net) 10 μ m fine definition, high-fidelity colour picture may further comprise the steps:

1) the colour original photo that will make is input to computer by the USM scanning of electron colour scanner with pattern, synthetic 1200dpi TIF electronics shelves photo;

2) by color management software electronics shelves photo toning is optimized;

3) utilize GSM2.0 software that the three primary colors of electronics shelves photo are carried out color separation, color separation becomes 7 passage: Cyan (cyan), Magenta (magenta), Yellow (yellow), Black (black), Orange (orange), Green (green), Blue (blueness); Make the coverage maximization in chromatogram of multiple color;

4) the electronics shelves photo that utilizes sensitization to handle shifts and outputs on the PS version (pre-coating light sensitive plate);

5) by offset press with design transfer to paper.

Further, above-mentioned method at paper surface making TPW 10 μ m fine definition, high-fidelity colour picture, wherein, in the step 1), described electron colour scanner is the SG8060 electron colour scanner.

Further, above-mentioned method at paper surface making TPW 10 μ m fine definition, high-fidelity colour picture, wherein, step 2) in, described color management software is photoshop color management software.

Substantive distinguishing features and obvious improvement that technical solution of the present invention is outstanding are mainly reflected in:

The invention provides at paper surface and carry out polychrome printing and Applied Digital color separation technology, sensitization technology copying and printing method, use that this method can obtain that uniform hue, stereovision are strong, clear picture, coloury fine definition high-fidelity coloured image in conjunction with modern printing technology.Utilize the image definition height of this fabrication techniques, levels are rich reproduces the natural colour of original copy and colour gamut true to nature.Have a wide range of applications in high-grade picture album, the high-grade art work, antique field such as duplicate.

S＝Y10％ M10％ C4％ BK15％

The colour cast original copy: colour cast generally weakens 3/4, or correction fully (deciding on requirement)

Level: bright, in, shadow is clearly demarcated;

Color: true, nature, coordination;

The clear degree of wash rice: hard mouthful of clear, bright and clean, nothing.

3.1 utilize GSM2.0 software that the three primary colors in the pattern are carried out color separation electronics shelves photo, color separation becomes 7 passage: Cyan, Magenta, Yellow, Black, Orange, Green, Blue.

4.1 utilize the sensitization technology that the electronics shelves photo transfer of technical finesse is outputed to (pre-coating light sensitive plate) on the PS version.

Image-forming principle by laser photocomposing machine is Cyan, Magenta, Yellow, Black, Orange, Green, Blue, by CTP (being called for short CTP) with design transfer on PS version (pre-coating light sensitive plate).
