About Olympus P-440

Dedicated photo printers differ from all-purpose printers as they are designed to print photos only, as opposed to text or graphics documents in addition to photos. They’re generally compact in size and light-weight, and some models even feature batteries that permit you to print without the requirement for an outlet. Most photo printers, as well as dye-sublimation (or dye-sub) printers, are engineered around a thermal dye engine, though there are a few that feature inkjet technology.

For several years, dye-sublimation printers were specialist devices used in demanding graphic arts and photographic applications. The arrival of digital photography led to the entry of this technology into the mainstream, forming the idea of many of the standalone, moveable photo printers that surfaced in the second [*fr1] of the 1990s.

The term “dye” within the name refers to the solid dyes that were employed in the method rather than inks or toner. “Sublimation” is that the scientific term for a method where solids (in this case, dyes) are converted into their gaseous type while not looking an intervening liquid phase.

The printing process employed by true dye-sublimation printers differs from that of inkjets. Instead of spraying little jets of ink onto a page as inkjet printers do, dye-sublimation printers apply a dye from a plastic film. A 3-pass system (that includes solid dyes in tape type on either a ribbon or a roll) layers cyan, magenta, yellow, and black dyes on prime of one another. The print head on a dye-sub printer uses tiny heaters to vapourise the dye, which permeates the glossy surface of the paper. A clear coat is added to safeguard the print against ultraviolet light. Although this technique is capable of manufacturing glorious results, it’s so much from economical. Whether or not a particular image will not would like any one of the pigments, that ribbon phase is still consumed. This is the explanation it is common for dye-sub printer compatible paper packs to contain a transfer film capable of producing the identical variety of prints. In addition, dye sublimation inks want a paper that permits the ink to remain on the surface of the paper.
