In the etching process, we often hear the word "film", for laymen, "film" is a very strange moniker, in fact, metal etching film proofing is a process used to check the color difference between the print and the customer sample, it can check the production quality of the previous processes through the process, the sample for the back of a large number of printing color tracking standards, so as to improve the quality management and control management of the link.

As the most important link on the etching process, thenMetal film proofingWhat do I need to pay attention to?

1、Metal film proofingIt is necessary to simulate the printing process through the proofing machine, so that the color value of the proofs can reach more than 90% of the color value of the customer's sample, so that the metal etching film proofing is close to the sample.

2、Metal film proofingThe price is relatively high, involving alterations to the text, images, and colors of the printed material early proofed film sheets will be scrapped.

3、Due to the high waste of resources caused by the altered scrap rate, the metal etching film process requires a digital draft before the metal etching film proofing.
