The quality of paper will directly affect the printing effect. The smoother the paper surface is, the clearer the printing effect will be. However, the order of paper printing and film coating has no great influence on the printing effect. If the surface of the base paper is smooth enough, it is better to print on the film first, so that the printed pictures and texts will not fade and stay longer. If the paper is not smooth enough, the film will be coated and then Printing is also a good choice.
