Screen printing semi-finished products generally need to dry on the paper holder for about half an hour. Due to the influence of temperature and humidity in the workshop, the stability of semi-finished screen printing products is difficult to control.
The key to managing the screen printing semi-finished products is to maintain a good environment for screen printing workshops. The following points should be achieved.
(1) The workshop is clean, tidy, dust-free and bright;
(2) The tightness of the workshop is good;
(3) The workshop should be equipped with temperature and humidity monitoring instruments;
(4) Facilities that can regulate temperature and humidity.
For gold/silver cardboard, sticker paper, aluminized paper, single-sided coated paper and single-sided offset paper commonly used in screen printing, since the front and back sides of such paper are of different properties or different states, When the environmental temperature, humidity, pressure and other factors change, the positive and negative sides will undergo different changes, so special attention should be paid to the storage and use of such semi-finished paper products.
In addition, the curling and deformation of such papers should also be checked before printing (it is possible to take several copies of each paper in the printing shop during the opening and closing process, and observe the changes at different time periods). If the curl deformation under normal conditions is quite serious, it is generally not suitable. Of course, the more positive approach is that printers and paper suppliers (manufacturers) often communicate with each other about the differences in the moisture content of the paper and the temperature and humidity environment in different regions to determine the appropriate parameters.
