Plate making belongs to graphic design, which is different according to the nature of work. There are machines such as inkjet engraving. As long as they are designed, they can type like printers. There are more complicated tasks, such as designing typesetting first, then assembling, printing film, and then drying the PS version and printing it on the printing machine. This kind of specialty is also what most people call computer plate making. The software used for plate making is generally PHOTOSHOP, CORELDRAW, illusrtator, freehand and so on. When using coerl~, use photo~ (PS for short) to process the pattern, use corel~ to design the layout, and then send the film; When using ill~, PS is used to process patterns, ill~ is used for typesetting design and imposition, and some of them are imported into pagemaker for typesetting (such patterns are mostly too many or beneficial to hair mask); There are also some designers who like to distribute directly in PS, but the files are generally large.
