In color printing, the color quality of general objects is regular. According to the rules of targeted and usable chromatograms summed up by book printing companies in actual printing production work, they are generally called printing chromatograms.
prints according to the chromatogram; printers can evaluate the quality of color prints according to the color rendering effect of various papers and inks in the chromatogram.
Theoretically speaking, the printing chromatogram can only be used for the reproduction process under the same conditions as paper, ink, plate-making process and printing process. Because the process of chromatographic printing involves many variable factors such as raw materials and various printing related conditions, only in the specific environment of our factory, we can use our existing color separation, screening, revision, and printing. , proofing, printing equipment and commonly used raw materials such as photosensitive film, printing plate, paper, ink, etc., only by exerting the technical level of the operators in each process of the factory can we print the chromatogram that has practical guiding role and reference value for the factory. In addition, with the passage of time, the physical and chemical properties of ink and paper will change, which will reduce the reference value of the chromatogram. Therefore, the printing chromatogram should be updated regularly, and the types and equipment models of various raw materials used in the printing process should be updated. Wait for the data to be recorded in detail.
Special printing chromatogram is very important in the production of printing industry. Understanding of special printing chromatogram is more convenient for the development of printing work. Of course, each China printing company is also different. This is mainly based on the different experiences summed up by different companies. It comes out, and the special printing chromatogram is also in the continuous development process. It has new changes and new chromatograms with the development of the printing industry, which all require us to have a further understanding.
