Silk screen printing machine smearing causes of silkscreen and prevent method?
After silkscreen printing, occasional smearing phenomenon, its main reason is caused by insufficient ink drying.Usually when the oxidation drying inks, smearing phenomenon is more, this is because the silk screen printing ink layer is thick, and oxidation drying ink surface drying speed and internal dry slowly, when the print and print or print, when in contact with other objects can produce smearing.General in the ink to join cobalt desiccant desiccant can improve the drying rate of ink or lead, have the effect of prevent smearing.In addition, in the pile of print, unfavorable and overmuch overlapping pattern (due to print too much backlog, also easy to produce smearing), print must be fully dry before stacking.Using evaporation drying ink formulations, can reduce smearing phenomenon.Strictly comply with technical requirements when printing, strictly according to the operation procedures, but also avoid smearing phenomenon is one of the most important measures.
