Types of printing is divided into: Direct Print Discharge Print Resist Print Pigment Print Specialty Print
Digital textile printing started within the late Nineteen Eighties as a potential replacement for analog screen printing. With the event of a dye-sublimation printer within the early Nineteen Nineties, it became potential to print with low energy sublimation inks and high energy disperse direct inks directly onto textile media, as opposition print dye-sublimation inks on a paper and, during a separate method employing a heat press, transfer it to the material.
Within the digital textile printing for communication a division needs to be created in:
low-volume dye-sub printers (e.g. ATPColor, D-Gen, Mimaki, Mutoh)
mid-volume wide format printers (e.g. ATPColor, Durst, Hollanders)
high-volume industrial printers.
The ‘textile market’ includes many alternative applications and needs. The meant use of the material is that the most vital start line to spot specifically what’s required to supply a particular end-product. A ‘textile’ product could vary from natural yarns for clothes, through to artificial fibres for flags and banners.
Production requirementsThe predominant textile media utilized in communication may be a polyester primarily based material. In the USA, nylon is commonly used for flags. In geographical region, polyspun material has been the selection of cloth for ancient flag printing. In today’s market, a plain-woven or unwoven polyester is that the actual customary. This differs from the predominant coated vinyl or pvc media utilized in the sign and show business. the assembly method has to work needs for the kind of ink: high energy sublimation (also called disperse direct), low energy sublimation (dye-sub), acid, reactive and pigment. In turn, the kind of ink chemistry has to work needs for the media (such as polyester, nylon, cotton, silk). supported the media and ink combination, the selection comes for infra-red fixation, heat-press sublimation or steaming.
Polyester material is written largely with dye-sub or disperse direct ink, though ultraviolet illumination and solvent inks (including HP’s latex formulation) may also be used. the nice good thing about sublimation ink is that the proven fact that the colorants can bond with the fibre throughout sublimation or fixation. the colors square measure ‘inside’ the media and don’t keep among the coating and on high of the media, because it is that the case with UV-curable formulations. Even latex inks on porous textiles will suffer from crocking problems or ‘rub-off’. Low energy sublimation ink is less complicated to print with, however has the disadvantage of colors attenuation faster; its ultraviolet illumination resistance, or light-fastness, is a smaller amount resistant than equivalents victimization high energy disperse direct ink. Dye-sub may also suffer from a ‘halo’ result which ends in less sharp pictures. The disperse direct ink may be a ‘stronger’ ink than the dye-sub kind, and this can be important for out of doors use, like for fence material, flags and banners: design can last longer.
Another good thing about aqueous-based sublimation ink is that the absence of venturesome parts as found in UV-curable, solvent and, even, in latex inks. once dead properly, direct to media printing with disperse ink is doable on uncoated materials and offers most print-through; this can be essential in applications viewed from each side, like with flag printing. As such, product is oversubscribed at a better margin, with a ‘green’ label and with a better quality. alternative media and ink combos cannot enable this.
