1. From the basic quality of paper: good heat transfer paper density, high whiteness, good uniformity, smooth surface;
2. From the point of view of the printing effect of paper: by printing the color contrast bar, we can see the paper's color reducibility, saturation, fidelity, etc., in addition, the paper's ink absorption performance, drying time can also be reflected;
3. Through the paper transfer effect: through the fabric transfer picture, you can see the paper reduction degree, residual degree, transfer uniformity, etc..
4. From the printing surface of the paper: can the paper coating is uniform, there is no leakage and black spots, color is consistent;
