Definition: The methods of transfering the design onto fabric at high temperature and pressure within very short time without any image distortion is called transfer printing.
Types of Transfer Printing:
- Sublimation Transfer.
- Melt Transfer.
- Film Release.
- Wet Transfer / Water Transfer
- Sublimation Transfer ( Dry, Vapour, Heat transfer ) : Here use volatile dyes. Dye is adsorbed from the vapour phase. In the first step the paper which the printing is done needs to be printed first. For that, collect the paper, make the print paste, print the paper and dried it at low temperature. In the seceond step, Sublime the paper and diffuse it with condensation. Diffusion again into the interior of the fiber of the fabric.
- Melt Transfer: In melt transfer design is printed on paper using a wax link. A hot iron is applied to its reverse face and presses the paper against the fabric. When the pressure is applied the ink melts and starts printing.
- Film Release: Similar to Melt transfer. Design is held in an ink layer.
- Wet Transfer / Water Transfer : Water soluble dyes are incorporated into a printing ink. Transferred to a moistened textile aqueous medium and printing is done.
Quality of Transfer Print Paper:
- Weight : 35-115 gsm
- Prevent the tearing in high speed printing
- Exhibit good “hold-out”
- Dimensionally stable
- Good realease of dye vapor
- Thermally stable
- Low permeability to dye vapor
- Smooth surface and metal free
