Cashen Diverse Solutions - Glossary [G]


In color reproduction, including computer graphics and photography, the gamut, or color gamut (pronounced `gæmət`), is a certain complete subset of colors. The most common usage refers to the subset of colors which can be accurately represented in a given circumstance, such as within a given color space or by a certain output device. Another sense, less frequently used but not less correct, refers to the complete set of colors found within an image at a given time. In this context, digitizing a photograph, converting a digitized image to a different color space, or outputting it to a given medium using a certain output device generally alters its gamut, in the sense that some of the colors in the original are lost in the process.


Giclée, pronounced "zhee-clay," is an invented term for the process of making fine art prints from a digital source using ink-jet printing.
The word “Giclée”, as a fine art term, has come to be associated with prints using fade resistant "archival" inks and the printers that use them. These printers use the CMYK color process but may have multiple cartridges for variations of each color allowing them to reach a larger color gamut.
