Quato
Quato was a successful German manufacturer of monitors, scanners and measuring instruments for color critical work. In August 2013, Quato decommissioned in and has since been discontinued.

Relative colorimetric
“Relative Colorimetric” is one of four rendering intents in gamut mapping.
Rendering intent
In gamut mapping, the rendering intent (rendering priority) is the strategy by which colours are converted from one colour space to another.
There are four types of rendering intents, defined by ICC: Perceprtual, Saturation, Absolute Colorimetric and Relative Colorimetric.
RGB
RGB stands for red, green and blue. Human colour vision is based on these colours.
RIP
A RIP is a raster image processor. A RIP is normally understood as a software, sometimes also a hardware or a software / hardware combination, that converts Postscript or PDF data of a page description language into raster points or image files that a “imagesetter” can expose to a plate, film or a proof output.
Roman16
The Roman16 test images are a collection of images specifically photographed for testing colour management applications.
Rotogravure
The ‘ProcessStandard Rotogravure’ (PSR) is a gravure printing standard provided by Fogra, the ECI and the German Printing and Media Industries Federation. The ProcessStandard Rotogravure is a standard developed exclusively for gravure printing.
Saturation
Saturation is a characteristic of the colourfulness of a colour. Alongside hue and brightness, saturation is one of the basic properties of a colour.
Scheufelen
The Scheufelen paper mill was one of the best known and most traditional paper mills in Germany for over 100 years.
SCTV
The SCTV, the Spot Colour Tone Value, is a ratio of the colorimetric difference between the hue, the substrate and the solid tone. SCTV uses L*a*b* as a basis, and in the best case also spectral data, and therefore works equally well with all spot colours, printing processes and papers and delivers a consistent result. When calibrating spot colours, SCTV reliably produces a result in which the 50 % hue of the colour is visually very close to the expected 50 % appearance. In the past, defined target values for …
Softproof
A soft proof is – in contrast to the classic “Hard Proof” on paper – a proof, which is soley displayed on a monitor.
Spectral photometer
Spectral photometers (or spectrophotometers) are high-quality colorimeters that can measure and accurately describe any colour.
Spectrophotometer
Spectrophotometers are high-quality colorimeters that can measure and accurately describe any colour.
Spot Colour
Spot colours are inks that do not belong to the CMYK colour space, but are printed as a real colour in an additional inking. The most important representatives are PANTONE, HKS and TOYO colours.
sRGB
sRGB is the most widely used RGB colour space, and was created for monitors by Hewlett-Packard and Microsoft in 1996. sRGB is the standard colour space of all inexpensive digital cameras and scanners.
Standard light Retrofit LED
An LED is a ‘light-emitting diode’ and in the graphics industry stands for the new ‘LED’ light, which has replaced older light sources such as neon tubes and tungsten lamps. Neon tubes are mainly known from the D50 or D65 standard light range. Today, LED light sources are predominantly used for standardised light in particular, as they can be spectrally adapted better and often emit a more harmonious light spectrum than neon light. In modern standardised lighting, it is possible not only to set up standardised light for one type …
Standardized light
A standardized light is called a defined light condition under which the viewer can view and assess prints or objects uniformly. The most important standard illuminants D50 are in accordance with ISO 3664:2009 for printmaker and for colour matching in prepress and press (colour temperature: 5,000 kelvin) and D65 (colour temperature: 6500 K) for internet graphic designer. D65 is the default setting for most monitors.
Sun Chemical
Sun Chemical is a major manufacturer of printing inks and as such is closely associated with PANTONE. Sun Chemical has a long history dating back to the 19th century. The company was founded in 1879 and originally began as a manufacturer of printing inks. Today it is part of the DIC Corporation, a Japanese chemical group. Sun Chemical plays a central role in the printing ink market, as it is one of the largest suppliers of printing inks and materials in the world. The company offers a wide range of …
SWOP
Specification for Web Offset Publications. Name of an organization and a collection of North American printing standards that define, among other things, the colour values of the primary colours cyan, magenta, yellow and black. They refer to the ISO standard, but are not identical. There are also SWOP specifications for proofing.
TL 84
Light of the neon fluorescent type F11 or TL84 is the classic neon light, the typical “department store lighting”. TL84 represents a three-band fluorescent lamp with 4000 Kelvin. This light is installed in many standard light boxes, to compare the reproduction of materials or surfaces with D50 or D65 standard light.
