In addition to excellent production materials, there is also a need to control the printing process. When customizing plastic packaging bags, one of the most common factors affecting the printing effect of packaging bags is the color difference of the original file. The goal of the printing and packaging industry has always been to reproduce the colors of the original documents perfectly! Under normal circumstances, it is not possible to make a printed product exactly like the original document. The color difference of the same batch is also an important factor affecting product quality. Plastic bags of different materials may also have color differences in the same position in the same area, which leads to differences in printing quality. The color difference between different batches of customized plastic packaging bags will also affect product quality. When different batches of the same product have color differences, it will bring customers unstable product quality. Finally, the ink will also affect the printing effect of the packaging bag. If the ink is not applied well, there must be something wrong with the bag. Too much or too little ink can affect the legibility of designs and handwriting, and the aesthetic quality will be much lower. Now that so much has been said.
