Glossary of terms:
There are a lot of terms that have been adopted by the printing industry. Hopefully the glossary below will help.
A-C D-F G-I J-L M-O P-R S-V W-Z
Describes the amount of colours that can be produced by a digital output device. In printing, the media and ink combination will also change the colour gamut available.
- GCR (Gray Component Replacement)
In CMYK full colour printing, black is made up of a combination of all CMY & K colours to produce a particular result. See also UCR
A process of placing dots in a pattern for production on a press. Usually formed into a rosette of colour that is visible under magnification.
Colour selection tools commonly used in design packages as an intuitive way to select a spot colour. HSB= Hue/Saturation/Brightness, HLS= Hue/Light/Saturation
an input folder found in workflow software such as a rip that is monitored by that software. A recognised file will be automatically loaded into the software for use.
This is the extension most commonly used in profiles. See the "Profile Basics" page
A restriction on the total volume of ink that can be used to produce any colour. Used to eliminate things like bleeding in a profile or rip.
A profile that describes the colour the file was captured by such as a camera or scanner. Also a profile of a device being simulated such as an offset proofer.
A way to increase the apparent resolution of a raster image using an algorithm to create dots in between existing pixels. Some digital cameras these days do this by capturing the photo twice and overlaying the 2 to double the number of pixels. This is often evident by slow shutter speed resulting in blurred photos if not held very still.
