How to choose digital proofing and traditional proofing? Urgent, I hope to be more detailed!

1, traditional proofing: the traditional proofing method is to put the film after the final version, and then dry the PS version with the traditional proofing machine, which has high proofing cost and long time. And because it is manual operation, the color depth is determined by the proofing technician, and the color will be different after repeated proofing. There are still many printing houses without CTP, and the design and typesetting of prepress documents are all done in prepress design companies or output centers. Sometimes there will be mistakes in the electronic documents provided by customers, and you can't see them without proofing. Traditional film proofing is too late, or some business secrets can't flow out. I wish I could make a sample at this time.

2. Digital proofing: Digital proofing is to interpret the arranged electronic documents into color separation files with the same printing effect through color management software and print them out with a high-precision large-format inkjet printer, instead of the traditional proofing process after film output, especially the CTP process of making plates directly by computer. Because film proofing is no longer needed, proof printing still needs proof, and the color of the proof should be consistent with the actual printing effect, so digital proof is needed to print the proof first and then use CTP. With the continuous development of inkjet printing technology, from the initial four-color inkjet to the current 1 1 color inkjet. In fact, from the beginning of seven-color inkjet, the color gamut space can be compressed, the ink hue can be simulated, and the color control software and hardware can really match the color of traditional printed matter. However, it is not convenient to print on imitation coated paper with special pigments, which is correct for the manufacturers of printing books and periodicals, and there is no problem with the color. However, compared with packaging and printing manufacturers, it is very difficult, because they often have to make not only proofs, but also finished samples for customers, and the special imitation copper coated paper has poor adhesion, and the post-processing such as laminating, bronzing, pasting E tiles, cutting boxes and die-cutting are not very easy to use. Now, Xiamen Good Impression Digital Technology Co., Ltd. has developed and produced a series of products of "printing with E", which can be proofed with actual printed paper, and the finished products can be directly proofed with actual materials such as paper, which is similar to the actual printing effect. This is also a good choice for design and creative companies to make physical samples, packaging and printing enterprises to contact business, support CTP and shorten the proofing confirmation process.
