Good afternoon, depending on the use environment and grade. Generally speaking, it is recommended to cover with coated paper, especially coated paper with a weight less than 250g, cookbooks, comics and other picture books. Due to the requirement of fine printing and frequent reading friction, the default screen printing ink of coated paper will be affected, especially the alcohol-soluble polyamide ink is not resistant to sweat and salt. Low-gram coated coated coated paper will become stiff and tidy, feel better, and it is easy to keep the picture indelible for a long time. I hope the above suggestions can help you.
