Scale colours
Scale colours are standardised variants of the process colours cyan, magenta, yellow and black, which were defined according to earlier fixed standards such as the ‘Euroscala’. The term refers to a colour scale that enables a colour-accurate and reproducible representation of these colours. The best-known standards for process colours are ISO 2846 (colour properties of printing inks) and ISO 12647 (standardised printing processes). The specifications of these four basic process colours ensured that printing results remained reproducible regardless of the machine, location or time. They were therefore mainly used in …
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.

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
Standardized lighting refers to defined lighting conditions under which viewers can uniformly view and evaluate prints or objects. The most important standardized lighting type is D50 for printmakers (colour temperature: 5,000 Kelvin).
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.
