Hi-Touch Imaging Technologies, Inc. or HITI is a leading manufacturer of dye-sublimation photo printers, which offer best digital camera output solution, with Dye Diffusion Thermal Transfer technology. Hi-Touch is presently developing exciting new dye-sublimation photo printers to meet the needs of a large number of home and commercial customers. In the large selection of photo printers from the company, the HiTi 630/640/730 line is specifically designed for consumer home printing and the HiTi 640DL/640Amphi on the other hand is designed for heavy-duty commercial printing and mini-labs.The HITI photo printers go together with most of the quality digital cameras, and enable the users to print lab quality digital photos with ease and enjoyment.

One such highly popular photo printer from HITI is the 640DL which is ideal for mini-lab and business applications, and is designed for heavy-duty continuous printing and batch printing. This photo printer is faster, durable and reliable. This printer uses the Dye Diffusion Thermal Transfer (D2T2) technology, and compliments those who take precision and quality seriously. The Thermal Print Head heats three ribbon panels that are coated with dyes in yellow, magenta and cyan. The heating process changes the dye to gas, which in turn diffuses into a thin receiving layer on top of the paper. A protective coating is then layered on top of the paper to protect the color against water and ultraviolet damage and to prevent the prints from fading.
