dye sublimation printing

Sublimation print can be classified as two types, viztransfer print and direct print.Transfer printThe images are initially printed on coated transfer paperas a reverse image of the final design, which isthen transferred onto polyester fabrics in a heat pressoperation. Under high temperature and pressure, the dye turns into a gas and permeates the fabric andthen solidifies into its fibres. The fabric is permanentlydyed so it can be washed without damaging the quality of image.

Direct print

The images are directly printed on treated polyester fabrics, which are then heated by heat-fixation devisethat fixes the colour on the fabrics. This method eliminates the need for transfer papers. This means no paper cockling and reduction in defects such asghosting and various wave or tiger stripes that arecommon in roll-to-roll transfer printing. This type needs an ink waste pit to collect excess ink andprevents it from staining the reverse side of the fabric.
