The printing color sequence of general spot color ink has no effect on the prepress process, but gold and silver special ink sequence is different, and the processing method of prepress CTP process is also different. Because the characteristics of gold and silver inks are different from those of four-color inks, their fluidity is poor and they are not easy to dry. There will be some changes in dry-press printing paper. This type of error caused by paper must be remedied before printing. If the print product requires a metal texture, it must be printed with spot ink. The image on this spot color ink spot color version is not removed. The spot color silver ink is printed first, and the four-color ink is directly imprinted.
Different images, the requirements of the process is different, the color sequence is different, the prepress processing method is also different, the same principle for the processing of text and vector graphics, but the general text and vector graphics should be removed, and to be Trapping processing . The gold and silver inks have strong hiding power. After the printing, the colors of the figures and figures cannot be reflected and the picture is very light. This is a taboo for printing. The first printing of silver will discolor the four-color imprint, so it must be removed.
Black ink is always imprinted in four-color printing. In spot color printing other than gold or silver, imprint processing is not related to color sequence. The black ink treatment in the spot color printing containing gold and silver is related to the color sequence. When gold and silver are printed first, black ink is used for imprinting, and black ink must be removed after printing, and reasonable Trapping must be done. Otherwise, K100 will look like K70, because the hiding power of gold and silver ink is strong.
In short, the development of computer-to-platemaking technology has a huge impact on the printing industry. We must keep abreast of the development of new technologies, constantly explore technological changes resulting from technological advancement, and maximize the advantages of new technologies before we can actually produce them. In the greatest benefit.
