What are the preventive measures for inaccurate silicone screen printing position?

Even if there are no problems with the screen size, printing machine, etc., the inconsistency of the shape of the printing material will cause inaccurate printing position. For example, in paper overprinting, after one color is printed and dried, the change in temperature causes the size to change. As a result, when printing for the second and third time, there will be inaccurate overprinting. When the printing material is plastic products, changes in temperature and humidity in the printing place can cause changes in size, affecting printing accuracy. In addition, the shape of plastic products and the conditions during molding (such as temperature and time) are not completely consistent. These must be considered when printing, and corresponding measures must be taken to make corrections in advance as much as possible.
