Block printing

The oldest technique of printing that also exists whose use is proscribed to the ornament of scarves and handkerchiefs. Color is utilized evenly to the picket block with completely different designs & the sample is stamped on the material akin to handmade textile printing

Sublimation

Virtually similar as switch printing however in sublimation the inks permeate and change into a part of the print media

Discharge printing

Also referred to as extract printing, it’s primarily based on the chemical destruction of the unique dye within the printed space. The discharging brokers used might be oxidising or lowering brokers, acids, alkalis and varied salts. For discharge printing, the bottom of the substrate must be dischargeable. It is strongly recommended that dyed discharge cloth must be pre-padded with 2-3 GPL Resist salt.

Resist printing

Within the resist type of printing type, Prepared-for-Dyeing (RFD) cloth is first printed with resist paste which prohibits the penetration of the dye into the cloth. The material is then dyed and subsequently, the resist paste is eliminated & leaving the specified sample.
