A colour model (or colour system) is an abstract mathematical method for determining and specifying colours and their relationship to each other.
It is sometimes referred to as colour space, although the latter is the concrete application of a colour model to a colour-producing method (printer, monitor, etc.).
A colour profile stores the characteristic features of a colour processing device.
These can be scanners, printers and monitors.
With the help of colour profiles it is possible to see what kind of colour range a device can represent.
Colour proofs (correct: contract proofs) are an ISO-certified test equipment for the graphic arts industry. Colour proofs simulate the colourfulness of offset or gravure printing in a colour and legally binding manner within the narrow tolerances of ISO 12647-7. Today, they are almost exclusively calculated using a RIP and then produced with inkjet printers on special proof papers.
1. standardised printing colours (process colours) for four-colour printing (CMYK), e.g. the Euroscale.
2. proof scale: A schematic ink sample that is produced during a press proof and serves as a basis for assessing a print in the production run.
During te process of colour separation, a colourful digital image is broken down into separate colour separations according to its colour components.
A colour space is based on a colour model, and is its concrete application to a colouring method (printer, monitor, etc). It therefore contains all colours that can actually be represented through this method and the associated materials.

Measured in Kelvin. The colour temperature describes the perceived colour impression of a light source.
Human colour vision is a complex process that enables us to distinguish millions of shades of colour.
A Contract Proof is a color-consistent and legally binding proof according to ISO 12647-7 The Contract Proof is currently the highest proof standard with the narrowest tolerances and is therefore considered a “contract” between the proof maker and the printing house.
In short: CD; describes the entire, uniform appearance of a company and is an important part of its corporate identity.
A successful corporate design creates brand awareness and recognition of the company, thus contributing to its brand positioning.
In short: CI; is the totality of the characteristic features of a company, its self-perception.
To “create a proof” means to make a digital proof or have a digital proof made. The term is synonymous with the word “to proof”.
The CRI (Colour Rendering Index) is a measure of the colour rendering quality of a light source. It indicates how well a light source reproduces the colours of objects in comparison to a reference light source, e.g. a daylight spectrum.
Cromalin is a proof printing process introduced by DuPont in the 1970s. A Cromalin proof is produced by successive exposures in layers on film, which is then laminated onto special paper.
Today, Cromalin no longer plays a role in proof production; it has been completely replaced by the cheaper and faster digital proof.
The removal of the background or insignificant elements from an image in order to perform image montages or to increase the optical effect.
Lines printed at the corners of the page to mark the final size of the design. The page is cut along these marks.
Also referred to as: trim marks, cut marks, crop margins.
The CropBox is the second largest box of a PDF file. It describes the part of a PDF file which is to be output to a printer or screen. It is often the same as the Mediabox.
CRPC originates from the American sector and stands for “Characterized Reference Printing Conditions”.
The CTF process is the ‘computer-to-film’ process in which the printing plates are not exposed directly, but an offset film is first exposed as an intermediate product, which then exposes the final printing plate.
