A way to describe the strength or vividness of a hue.
The angle of a halftone screening as measured from the horizontal axis. Black and white are normally at 45°. When process printing black is usually at 45° , cyan at 105°, Magenta at 75°, Yellow at 90°
- Skeleton Black Generation
Black in replaces calculated amounts of cyan, magenta and yellow ink. Using black also gives better gray neutrality. See also GCR
- Spectrophotometer / Spectro
Spectro (spectral - meaning colour) -photo (to capture) -meter (measurement). A device used to measure colour (usually in cielab) to select colour, calibrate or profile a device. Used in many industries such as the print industry, paint colour selection, wine creation, along with many other scientific uses.

This is a type of coating process for inkjet media. When the inkjet ink hits the coated area of the media, the coating swells up and later forms a hard barrier protecting the print. The advantage to this media is that it protects the ink very well against pollutants, although the disadvantage is a much slower drying time compared to Microporous media types.
These print heads use a small element in the nozzle that heats a small air bubble. As this bubble heats up it expands and pushes out a drop of ink (hence why Canon refer to it as "Bubble-Jet"). These print heads are cheaper to produce allowing easy and economical replacement although they do not last as long. Manufacturers such as HP, Kodak/Encad, Canon use this technology.
- TIFF (Tagged Image File Format)
A standard raster format for graphic files
- UCR (Under Colour Removal)
Changes the use of CMYK where they print together wo black ink to produce a neutral gray. See also GCR
A graphic file format that uses mathematical relationships to create the image. Great for great enlargement ability with small files.
