study on perfecting offset printing sheet polyamide or polyester fabric.

摘要

The present invention relates to a method of printing on polyamide and/or polyester fabrics by using the offset process, characterised in that the following various means are employed in combination: - the use, in the photogravure of a 175 screen colour selection, of the process known as "sub-colour contraction" which will enable us to obtain a tone with an ink charge of less than 150% for the same definition; - the use of a printing machine in which the fabric is picked up and conveyed continuously through the entire machine; - printing in a single pass on a single machine; - the use of printing liquids, ink or water, containing drying accelerators; - and, after printing, the coating of the printed surface of the fabric by the mechanical bonding of the varnish (polyvinyl chloride resin) to the textile.
