image processing technology provides data compression for the color
transformation tables which are embedded in printer firmware for optimal color
concept is to be used in digital printing devices, such as color ink jet and
color laser printers. Color look-up
tables provide transformation between various color spaces, such as device
independent color spaces (CIELAB) and device-dependent color spaces (CMYK),
which can depend on print media and artistic preferences. These color look-up tables are embedded
in printer hardware, typically on expensive flash memory.
technique provides color look-up tables in a compressed form, with no compromise
in quality. The compression ratio
achieved is 3.45.
