CN102367022A - Method for manufacturing colored image with high definition and high fidelity on surface of grey paper board - Google Patents

Abstract

The invention provides a method for manufacturing a colored image with high definition and high fidelity on the surface of a grey paper board. According to the invention, a required colored original art work photo is inputted into a computer through USM scanning by using a color scanner, or an image in a digital camera is directly used, and a TIF electronic-version photo with a definition of 1000dpi is syhthesized; the electronic-version photo is processed through color adjusting optimization by using s color managing software; color separation is carried out upon three primary colors of the electronic-version photo by using a Profile Maker software, such that 6 channels of Cyan, Magenta, Yellow, Black, Orange and Green are obtained; coverages of various colors in a chromatogram are maximized; the processed electronic-version photo is transferred onto a PS plate through sensitization; and the image is transferred onto a grey paper board according to a color sequence of Cyan, Magenta, Yellow, Black, Orange and Green by using an offset printing machine. With the method provided by the invention, the manufactured image has a high definition and plentiful layers. With the method, natural colors and lifelike gamut of the original image are reproduced.

Description

The method of making fine definition, high-fidelity colour picture on ash version paper surface

Technical field

The present invention relates to method at ash version paper surface making fine definition, high-fidelity colour picture.

Background technology

In the prior art; Through 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 through 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 fine definition, high-fidelity colour picture on ash version paper surface is provided.

The object of the invention is realized through following technical scheme:

Method in that ash version paper surface makes fine definition, high-fidelity colour picture may further comprise the steps:

1) the colour original photo that will make is input to pattern computer or directly uses the Digit camera picture through the USM scanning of electron colour scanner, synthetic 1000dpi TIF electronics shelves photo;

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

3) utilize ProfileMaker software that the three primary colors of electronics shelves photo are carried out color separation, color separation becomes 6 passage: Cyan (day lion cyan), Magenta (day lion magenta), Yellow (it lion is yellow), Black (day lion black), Orange (it lion is orange), Green (it lion is green); 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) through offset press with Cyan (day lion cyan), Magenta (day lion magenta), Yellow (it lion is yellow), Black (day lion black), Orange (it lion is orange), Green (it lion is green) successively look preface with design transfer to ash version paper.

Further, the above-mentioned method of making fine definition, high-fidelity colour picture on ash version paper surface, wherein, in the step 1), said electron colour scanner is the SG8060 electron colour scanner.

Further, the above-mentioned method of making fine definition, high-fidelity colour picture on ash version paper surface, wherein, step 2) in, said color management software is photoshop color management software.

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

The invention provides at ash version paper surface and carry out the copying and printing method that polychrome printing and Applied Digital color separation technology, sensitization technology combine modern printing technology, use that this method can obtain that uniform hue, stereovision are strong, clear picture, coloury fine definition high-fidelity coloured image.Utilize the image definition of this fabrication techniques high, 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.
