Plural primary color print method

Abstract

The invention discloses a plural primary color print method, which combines digitalized plate making technique and picture processing software. The method comprises the following steps: firstly, utilizing the picture processing software to modify and draw pictures to be printed, making pictures including a plurality of primitive colors, and adopting the digitalized plate making technique to carry out plate making on the pictures and then printing the pictures; and secondly, making printed printing materials into electronic-file pictures to input into a computer, comparing the pictures to be printed and the electronic-file pictures, if the effect of the electronic-file pictures is the same as the effect of the primary pictures to be printed, stopping printing, otherwise, modifying and drawing the electronic-file pictures by using the picture processing software to make electronic pictures, adopting the digitalized plate making technique to carry out plate making on the electronic pictures, and printing again on the materials printed last time. The invention has the advantages of avoiding the phenomenon that some colors in first-time printing can not be printed, ensuring printing materials to have rich and bright colors after several times of adjustment and printing, and enabling the colors to be closer to primary pictures.

Description

technical field [0001] The invention relates to a printing method, in particular to a printing method combining computer and picture processing technology. Background technique [0002] As we all know, printing is a method of copying text or images on the layout, and painting the layout with color, and on this basis, transferring and printing the copied text or images on the layout by means of pressure or turning pressure. It is a technology to fully reproduce the original text or image on the surface of various materials. [0003] At present, there are many kinds of printing technologies, for example, four-color printing. However, this printing process, although it is a printing process that uses yellow, magenta, cyan primary color inks and black inks to reproduce various colors of color originals, can meet the requirements of general printed matter and customers to a certain extent, but four Because the color printing process only uses four colors for printing, that is, ...

Problems solved by technology

However, this printing process, although it is a printing process that uses yellow, magenta, cyan primary color inks and black inks to reproduce various colors of color originals, can meet the requirements of general printed matter and customers to a certain extent, but four Because the color printing process only uses four colors for printing, that is, yellow, magenta, cyan primary color ink and black ink, the printed matter will be too monotonous and boring, and the color will lack richness and vividness.

[0004] In addition, in reality, many colors cannot be well expressed by using a single four primary colors. In the case of general printing, after printing once, if it is printed again, it will not come out what we want. color, but come out all pitch black phenomenon
