Dye-sublimation branding (or dye-sub printing) can be a computer printing technique which usually uses heat to airport transfer dye onto materials maybe a plastic, card, paper, or even fabric. The sublimation name was first applied because dye was considered for making the transition between your solid and gas states without experiencing a liquid stage. This comprehension of the process was later shown being incorrect, as there is some liquefying from the dye. Since then, the right name for the process happens to be known as dye-diffusion, though this technically-correct term has not supplanted the original brand. [1] Many consumer and professional dye-sublimation printers were created and used for generating photographic prints, ID cards, clothing, and more.

They are not to be perplexed with 'dye sublimation warm transfer imprinting printers', which use special inks to build transfers designed to always be imprinted on textiles, and in which the dyes do indeed sublimate. [1] These are done at lower temps but higher pressures, in particular in all-over print operations.

For ID card printing, text and bar unique codes are necessary, and they are printed by way of an additional black panel about the (YMCKO) ribbon. This extra panel performs by thermal transfer printing besides dye diffusion: a whole layer, instead of just a number of the dye in the core, transfers from the ribbon into the substrate at the pixels defined from the thermal head. This complete process is then oftentimes called dye diffusion energy transfer.
