Folding color printing process

Analysis of the original color: the color palette for the original samples, in order to add color blindness, it is necessary first of all to the original colors were analyzed to determine the proportion of demand hue and colors of ink. Analysis of the first assuming the original color measurement instrument and the human eye than the hue contact approach. RGB ink printing using chromatography to determine the proportion of relatively simple combination, can the percentage content of the accounting RGB ink and white ink colors according chromatography marked dot area.

 

 

Color: In accordance with the ratio calculation, first weighed dispatched a small amount of ink colors. Ink and carefully compare the original color from time to time, when the two colors close to the desirability of the transfer ink scraping samples of paper-like contrast scraping sterile line, predicament repeatedly until it is fully consistent with the two colors. Than the color, the ink should be playing uniform, and ink thinner the better, in order to guarantee the accuracy of the hue of the color swatch, paper and paper should be used when printing the same. Adjust the brightness and saturation by adding white ink and black ink is completed. When the demand for participation in white, black ink should be weighed carefully extraordinary accuracy.

 

 

After the assignment out of ink manuscript arrived requirements, according to the proportion of bulk ink dispatch. A number of jobs as the amount of ink in the dispatch of this world is determined by the type of paper size, image size, number of copies, and a lot of amount of loss, and the more the principle of not less.

 

 

Records: complete preparation will transfer ink color inks used in the ratio, varnish, dry oil, ink type, quantity, manufacturer and other information published in detail, as a reference when lunch later with ink.

 

 

Other items remain hardship: In the original analysis, colorimetric, the best standard light source or light sources close to the sun, but also pay attention to the ink film to be monotonous and then compare the color to add visual errors. Try to use the line close to the primary color ink or color when other single color ink, color ink excessive use of color, brightness and saturation, the worse the consequences and impact printing. So when color ink species as possible, the best choice for a consistent ink manufacturers produced products.

 

 

When the toner to fully inquire factory equipment everyday printing speed and printing pressure, and better control of ink viscosity. Under substandard printing speed and pressure printed out printed materials hue shades will not, therefore dispatched at low demand for good ink will be printed on the normal speed after fast start to be checked again with the original, so the existence of color constitute Mi throw .

 

 

After the ink is transferred out, assuming found printed on the machine out of the color sample with the original margin of error should be corrected. Color change to the fountain, ink roller clean to avoid episodes cast clean and unclean. Spot color ink residue left over after printing, you can still work with the new manuscript dispatch hue, saturation, but often partial gray, extraordinary is the ink from the fountain to retrieve the remaining residue, it may have been somewhat useful emulsified or printability changes.
