ABSTRACT:
The textile-printing industry is very interested in bypassing the laborious and expensive production of transfer printing papers, together with the required engraving of rolls. It has been found that this demand can be satisfied by electronically recording and reproducing any motif and transferring to textile material by means of halftone systems.
According to the invention, the dyestuffs are continuously transferred by halftone systems from four differently and uniformly colored papers one after the other. To obtain a good picture, 10 to 20 halftone dots per cm are advisable for pressing the paper to the surface of the textile material. Either the halftone dots themselves are heated, or they press the textile material and paper onto a heated surface. The halftone dots are electronically actuated in correspondence with the scanning of the motif.
The process can be carried out particularly simply on a flat screen printing machine, because this machine dispenses with the need to perform the color transfer very rapidly from the paper uniformly colored with dyestuff to the PES material.
