Epp - enhanced parallel port
| Глоссарий терминов по видеокамерам |
Epp enhanced parallel port the newer hi-speed, bidirectional printer port on modern computers. some older digicams and scanners use the epp port to transfer data.

Bidirectional, английский
Operating in both directions. bidirectional couplers split or combine light the same way when it passes through them in either direction. bidirectional transmission sends signals in both directions, sometimes through the same fiber.

Eri-jpeg, английский
Extended range imaging technology, a new file format used in kodak professional digital cameras. this proprietary technology offers an innovative image file format similar to a jpeg, but with the dynamic range and color gamut information of raw dcr camera files. extended range imaging technology files allow you to easily open, edit, and print jpeg files within your jpeg workflow. your jpeg files are captured directly in the camera. with eri, you`ll have the extensive editing, color balance, and color compensation capabilities of raw digital negatives for applying to your jpeg files.
Dye sub, английский
- Limation is a printing process where the color dyes are thermally transferred to the printing media. dye sub printers use the cmyk (cyan, magenta, yellow, black) color format and have either three ribbons (cyan, magenta and yellow) or high-end printers have four cmy plus a black. the paper is run in and out of the printer four times, once for each color and then a fourth time when a protective overcoat is applied. dye sub is continuous tone printing, it prints tiny square dots each of which is denser in the center and lighter on the edges. these dots can be varied from almost no dot at all to an almost completely solid dot. the dyes are transparent so different colored dots can be printed on top of each other to form any one of 16-million colors. this is known as the subtractive color process. dye sub prints rival conventional photographs in both their color gamut and longevity with water and uv resistant qualities. for the sake of accuracy we must state that most printers today that claim to be dye sub type printers are actually dye diffusion. the complete technical name for this process is dye diffusion thermal or d2t printing. to achieve true sublimation printing requires a laser to vaporize the dye material. the common 4x6 dye sub or the bigger ones that do up to 8x10 prints like the olympus p-400 or kodak pro 8500 heat the dye material with a thermal printhead and use pressure rollers to push the ribbon into contact with the paper and then diffusion occurs.
- Dye sublimination is a printing process where the colour dyes are thermally transferred to the printing media. the printers use cmyk colour format. the paper is run in and out of the printer 4 times, once for each colour (c, m and y) and a fourth time when a protective overcoat is applied. dye sub is continuous tone printing, it prints tiny square dots each of which is denser in the centre and lighter on the edges. the dyes are transparent so different coloured dots can be printed on top of each other to form any one of 16 million colours.
