Abstract
A printing technique without half-tone dots for paper, silk and fabrics includes electronic colour separation of original copy, making plate, plate copying and printing. It features that the many colours in image are separated to obtain particular continuous tone colours to make colour-particular negative film in the colour separation steps, the linking liquid and photosensing liquid are uniformly coated on frosted glass and then baked in the plate making step, the negative film is used to make plate in the plate copying step, and a cross chromatography with window is used in the printing step. Its advantage is clear printed image without half tone dots and lines.
Description
The present invention relates to a kind of printing technique without net points.
Existing printing technology is through electronic scanning, screening, plate-making, printing down step with a width of cloth colored original, on printing machine, print, in the electronic scanning step, the multiple color in the chromatic image is divided into black, red, yellow, blue four look egative films, level with visual fading of light and shade farming, by flat centimetre of site reflection that adds varying number whenever, then four kinds of color double exposures are become an images, realize trichromatic process printing.The principle of this method is based on the vision mixing principle of human eye, promptly when the ratio of the distance between two sites and two distances of site between human eye less than 1500 the time, just human eye can not differentiate two sites, as same point.If but the diameter of site is too big, image just can blur, color reflects untruely, if the site diameter is too little, in the Plate making printing process, cause scumming easily, dot loss, site are out of shape, lose semi-tone easily, and chromatic rendition, color saturation after the printing are unsatisfactory, can't reach the artistic effect identical with original work.Net-point printing is arranged when reflection original copy color, the complex process of many indeterminable problem, particularly screening can occur, the complex process when just causing printing.
The purpose of this invention is to provide a kind of printing technique without net points, make printed image clear, do not have the site netting twine, reflect the content of original copy truly.
Technical scheme of the present invention is: this printing technique without net points, be with original copy through photograph or electronic scanning, plate-making, printing down, print steps, it is characterized in that:
In the electronic scanning step, the multiple color in the image is divided into the single-minded color of continuous accent, make special look egative film;
Colour-separation drafting then, plate-making, in the plate-making step, evenly coating connects liquid and sensitization liquid on the ground glass plate, dries then, washes, dries, negative plate-making, and exposure makes the exposed portion sclerosis, produces little wrinkle;
In the printing down step, use negative plate-making;
In print steps, with form cross overprinting method, be printed on the chromatography mark of cross hairs, open the form of a geometric form, carry out chromatography from the back side of printing.
Above-mentioned connection liquid is the mixed liquor of sodium metasilicate and beer.
Sensitization liquid in the above-mentioned plate-making step is the mixture of dichromic acid amine, gelatin, styrax, potassium bichromate, plumbi nitras.
Bake out temperature in the above-mentioned plate-making step is 40～70 ℃.
Advantage of the present invention is: this technology is the formation method of achromaticity system, can make printed image clear, do not have the site netting twine, reflect the content of original copy truly; The printing of use ink special, color rendition rate height, tone is continuous; Reproducible various calligraphy and painting at all times, historical relic and picture, its print effect almost can reach the degree of mixing the spurious with the genuine; Be applicable to that the various carriers of printing are as various paper, thin silk fabric thin,tough silk, textile etc.
Below in conjunction with embodiment the present invention is described in detail:
This printing technique without net points, be with original copy through photograph or electronic scanning, plate-making, printing down, print steps, wherein:
In photograph or electronic scanning step, the multiple color in the image is divided into the single-minded color of continuous accent, each color is respectively made a egative film; Colour-separation drafting then, plate-making; In the plate-making step, evenly coating connects liquid and sensitization liquid on the thick ground glass plate of 1～20mm, connecting liquid is the mixed liquor of sodium metasilicate and beer, sensitization liquid is the mixture of dichromic acid amine, gelatin, styrax, potassium bichromate, plumbi nitras, oven dry, bake out temperature are in 40～70 ℃ of scopes then, in an embodiment, can select 40 ℃, 45 ℃, 50 ℃ when oven dry connects liquid, can select 55 ℃, 60 ℃, 65 ℃ during oven dry sensitization liquid, the ground glass plate thickness is about 10mm; In the printing down step, through negative plate-making, exposure process, make the exposed portion sclerosis, produce little wrinkle, wash again, dry; In print steps,, be printed on the chromatography mark of cross hairs, opening the form of a geometric form, carrying out chromatography from the back side of printing with form cross overprinting method.
Claims (4)
