Our goal with this glossary is to assist printshop owners, managers, and printer operators, as well as students of graphic design, photography, and printing. This glossary should also be informative for photographers, artists, giclee ateliers, and printing shops of all kinds, especially signage.
This glossary is essential for the newbie and intermediate user, as well as for any new employee. The terms contained within are related to aspects of color management, including basic information pertaining to color theory as well as information directed more towards the color management workflow.
The present version (2017) is a major update over previous years (October 2008, November 2008 and updated again in May 2009), but this version will be updated about once every year.
FLAAR Reports glossary of Color Management
Achromatic color, color-lacking hue, meaning that it either totally reflects or absorbs light. Examples of achromatic color include white and black.
Banding are horizontal lines on a print. Banding is an undesirable effect of all sizes and shapes of inkjet printers, both piezo and thermal. Banding may be present only across one color (usually a solid black or solid cyan). Or banding may be continuously across the entire range of colors. Banding is a result of the path of the printhead across the media. There may be lines or absence of image within the bands.
Calibration (standardizing) vs characterization (describing). Calibration returns the device to a known state by checking the state you find it in then adjusting it to a preferred state, which is a known state. You calibrate first then characterize it. Initial calibration of an output device begins with linearization of that device.
CMYK stands for Cyan, Magenta, Yellow, and blacK or Key color (based on traditions in printing from the previous century). Otherwise referred to as the subtractive primary colors. The colors that are used in the inkjet printing process.
Embedded profile, an ICC profile that is attached to a file, which can be used by other applications.
GCR, Gray Component Replacement. This process replaces portions of the CMY ink with black ink throughout the image including highly saturated areas, as opposed to UCR (Under Cover Removal), which removes CMY primarily in shadow areas which are supposed to be neutral
Halftones, the series of dots that comprise a continuous tone image.
ICC, International Color Consortium.
Pantone is a company specializing in producing color standards primarily for printing with traditional presses such as offset presses. As printing has become more digital and more with inkjet machines, Pantone has done its best to become relevant also to this new technology (but is only successful to a limited degree).
Pigment, colorant used in the inks for printing. Ink pigments last longer in the sun than do dye molecules that are used in dye inks.
RGB, stands for Red, Green, and Blue color. These are the additive primary colors. RGB images use these three colors to reproduce up to 16.7 million colors on-screen. RGB is the standard color model for output displays such as monitors and projectors.
Spectrophotometer is an instrument that measures diverse characteristics of light that is either reflected from or transmitted through a surface.
FLAAR Reports has separate glossaries on UV-cured flatbed printers, Solvent printers, wide-format inkjet printers for textiles, CNC finishing equipment and is preparing a glossary on digital inkjet inks and media & substrates for the digital wide format printer market.
