I'm from a photo studio. Of course, the photo studio prints well, but there is a kind of thermal dye sublimation that can't compare with the quality of printing. The printing effect can be completely waterproof, with better color, higher resolution and better effect, but thermal sublimation printing paper is several times more expensive than printing. It is a way of printing by yourself, which is faster and has better effect. 4R wants 1.5-2.0 yuan/piece. The actual digital printing only needs 0.7- 1.0 yuan. You can find Jinlida digital photography spot on the Internet.
