Screen Printing

By far the best results and the most brilliant colors are achieved by chemical damp through-printing. This is a screen printing process in which dispersion dyes are printed "wet on wet." Special colors and spot colors are printed basically as true colors and are not developed through 4c halftoning. Modern printing lines are approximately 75 meters long and make it possible to print up to 10 colors in one cycle.

After printing, the material runs through a damper in which the colors are fixed thermally. By means of hot steam at a temperature of 195° C and under high pressure, this process opens the fibers which take up the dye.

Afterwards this dye is bonded to the material and can no longer be washed out.

During printing, there is of course so much dye applied that it can not be completely absorbed by the fibers. For this reason, it is necessary to wash the flags one more time after damping and to dry them afterwards. Not until then can the flags be separated and finished.
