Diffirentiate Sublimation and Decal?

Answer 1

An interesting question that required some research:

I guess you're looking for the difference 'tween a dye sublimation printer and decals. SIMPLY put:

a) Sublimation printing uses HEAT to transfer the image from a gel-base to paper (Photo-printers)
b) Decals use water to transfer the image from paper to a surface. (I suppose that decals could be created using dye sublimation printing).

Below is a long description of dye sublimation printing:

A printer that produces continuous-tone images that look like photographic film. Also called a "thermal dye printer," the print cartridge contains a cellophane ribbon with panels of dye the same size as the page to be printed. There are four panels for each print: one each of cyan, magenta and yellow (CMY) and a final clear coat that allows the print to be handled immediately without smudging. Special dye-receptive paper is used.

Because the same amount of ribbon is used no matter how much color is in the image, the cost of ribbon and paper is always the same per print. Consumables for dye sublimation printers generally cost more than for ink jet printers.

Heat Releases the Dyes

The paper and ribbon are passed together under the printhead for each color panel. The printhead contains thousands of heating elements that produce varying amounts of heat. The hotter the element, the more dye is released. By varying the temperature, shades of each color can be overlaid on top of each other. The dyes are transparent and blend into continuous-tone color.

The "sublimation" means that the dye turns into a gas without first turning into a liquid. See thermal wax transfer printer and printer.

Answer 2

Sublimation uses heat to transfer designs to your medium. Decals are preprinted designs on various mediums that are transfered by water or heat to another surface.
