Dye sublimation transfer paper for polyester is one of the common printing products in the printing industry and is also the main business of most printing plants. For batch printing of albums, we all need to proof and color the albums to prevent printing errors or the printed effect being different from the expected effect. There are two methods for album proofing, namely digital proofing and traditional proofing. First, let’s briefly introduce what digital proofing and traditional proofing are.

The so-called digital proofing is to connect a computer to a printer and output it directly. The advantages are: time saving, low cost, and controllable color (of course, now proofing machines are also divided into laser machines and inkjet machines). The disadvantage is that it is limited by the size and thickness of the paper. Traditional proofing generally requires the production of pieces, printing, and machine proofing. The disadvantages are: time-consuming, expensive, and low color controllability. The advantages are: it can be used for various media and thicknesses. Proofing.

Let’s make a more detailed comparison between digital proofing and traditional proofing.

Especially for batch printing of albums, because the printing cost is very high and the order amount is large, even if the customer does not request proofing, the printing company must make proofs and colors. Printing proofing is a key process in which after the design and typesetting is finalized during the printing period, proofs are printed first for customers to sign. It is related to the acceptance standards for large quantities of printed matter after placing orders, and is also the basis for collecting money after delivery, so it is called It is a critical process. In particular, standard digital proofing is an important part of the printing factory's implementation of a face color management system.

1. Traditional proofing:

The traditional proofing method is to release the film first after finalizing the draft, and then use it as a PS version.

The traditional proofing machine with round and flattening method has high cost and long time for proofing. Moreover, since it is a manual operation, the color depth is decided by the proofing technician, and the color will be different after repeated proofing. There are still many printing plants that do not have CTP. The design and typesetting of printing documents are completed at printing design companies or output centers. Sometimes there are errors in the electronic documents provided by customers, which cannot be seen without proofing, and it takes time to make traditional film proofing.

If it is not enough, or there are some business secrets that cannot be leaked out, then you will think that it would be nice if you could make the samples yourself.

2. Digital proofing:

Digital proofing uses color management software to interpret the typed electronic document into a color separation file with the same effect as the actual printing, and prints it out with a high-precision, large-format inkjet printer, replacing the traditional proofing process after outputting the film, especially when using Computer-to-plate CTP process, because there is no need to produce film proofs, but sample printing still requires proofs, and the color of the proofs must be consistent with the actual printing effect.
