Why there are a lot of small cracks appeared after acrylic with silk screen a period of time, it will not effect the appearance but also feel not good.
There are several factors for the cracks, first is the bad material, the another is ink’s quality. If because of the bad material, we can find a piece we did silk screen before the remaining leftover crack, to judge, using the same ink, if will not appear crack, we can confirm that the material is no t good. Maybe with too much water, you can try the acrylic sheet baking temperature 60 degrees 30 minutes in the screen printing.
If still with crack, it must because of the ink. Because acrylic effected by solvent corrosion, will cause the cracking phenomenon.so if the use of ink is not applicable, such as toluene, solvent ink, may make the acrylic sheet cracks after screen printing. The crack can be used when no problems before printing ink (different color silk screen printing ink), whether the problem quickly, reduce the time and avoid the waste of materials.
In addition to, as plate electrostatic dust, in the screen printing or fill in the paint before the use of suede with soap and water or 1% soft cloth to wipe clean, in order to achieve the cleaning effect. It is very important to acrylic board printing, select the kind of quality is better, especially for the display stand products, acrylic products, the appearance of transparency requirements are very high. The ink is relatively better, and ink quality directly affect the appearance.
