The mesh mark preventing measures have?
Silk screen printing ink membrane surface screen, can appear sometimes appear screen traces of the main reasons for poor mobility of ink.Screen printing process, when the plate is raised, transferred to the ink on the substrates on its own floating bridge network, make the ink film surface smooth level off.If ink liquidity is poor, when the screen plate is raised, the ink flow is small, can't screen marks fill and level up, won't get the ink film surface smooth level.In order to prevent print traces appear on the screen, can adopt the following methods.
(1) using liquidity big ink for printing.
(2) consider using slow drying of printing ink, increasing the flow of the ink ink unfolding and curing time.
(3) as far as possible when the plate making use a finer monofilament wire mesh.
Printing position is not accurate prevention measures is what?
Even if the screen size, printing machine, etc are no problem, but the shape is not consistent, etc can cause printability position is not accurate.Such as paper color printing, color printing after drying, temperature change, change their size, results in the second and third printing, misregister fault will occur.When printing material is plastic products, printing place the change of temperature and humidity can cause the change of their size, printing precision, and the shape of plastic products, molding process conditions (such as temperature, time) are not completely consistent, printing must be considered when, take corresponding measures, as far as possible in advance calculation for rectifications.
