The so-called table printing refers to printing on the surface of the film. The printing ink is exposed to the outside of the product, so the ink adhesion is required to be good, with considerable wear resistance, light resistance, frost resistance, and temperature resistance. It also achieves excellent quality in gloss. The main substrates are PE and PP.
Inside printing is a printing method that uses the reverse graphic printing plate to transfer the ink to the inner side of the printing film and presents the positive graphic effect on the outer side of the printing substrate. Its advantage is that it is colorful, does not fade, does not fade, moisture-proof and wear-resistant. With the widespread use of composite materials, the use of printing methods to avoid ink fading and reduce the risk of contamination of the packaging contents by printing ink.
Surface printing color printing color sequence is white ink first, black ink last unit printing; On the contrary, black is the first color sequence, and the arrangement of special printing color sequence also needs special treatment depending on the situation.
