Optical brighteners are additives used by paper manufacturers to make a paper look whiter and brighter.
Offset
Offset printing is an indirect printing process.
Indirect means that the printing plate and the substrate do not come into direct contact with each other, but a medium in between is used as a transfer medium.
It is the most widespread printing process.
Online proof
An online proof (correct: contract proof) is an ISO 12647-7 certified test equipment for the graphics industry. It is called online because it is ordered “online”, i.e. via the Internet.
Opacity
The term opacity refers to the opacity or covering power of a colour. A colour with high opacity is opaque and allows little or no light to shine through. A colour with low opacity is transparent or translucent and allows some or all of the light to pass through. The opacity of a colour depends on factors such as the concentration of the pigment, the type of pigment, the layer thickness and the type of substrate on which the colour is applied. Pigments with higher opacity generally produce colours with …
opaque
A colour is described as opaque if it is non-transparent, i.e. light cannot shine through it and no objects or colours are visible behind it.
OPP
‘OPP’ stands for “Oriented Polypropylene”, a type of plastic film. OPP film is made from polypropylene and is characterised by its orientation. The orientation of the material is achieved by a special manufacturing process in which the film is stretched to improve its physical properties. OPP films are transparent, glossy and have a smooth surface. They offer high clarity, are tear-resistant, water-repellent and have a good barrier effect against moisture, oils and gases. These properties make OPP films versatile and they are used in various areas, especially in the packaging …

percabsolute
The rendering intent ‘perceptual absolute’ is not known or established as an independent rendering intent in colour processing and colour management. The term refers to a combination of the rendering intents ‘perceptual’ and ‘absolute colourimetric’, meaning that the aim is to achieve a colour reproduction that is both visually appealing (perceptual) and precise and accurate (absolute colourimetric). With Fiery XF, for example, the rendering intent can be used to convert photographs that originate from a large source colour space such as AdobeRGB into a smaller target colour space.
perceptual
The ‘’perceptual‘’ rendering intent is used in colour management to achieve the most pleasant and visually appealing colour reproduction possible. This rendering intent is based on the human perception of colours and takes into account how we perceive and interpret colours. When using the ‘perceptual’ or ‘perceptive’ rendering intent, the colour values of the original are adjusted so that they appear natural to the human eye. The colours are converted in such a way that they have as similar a visual effect as possible in the target colour space as …
Photoshop Softproof
The Adobe Photoshop software offers a so-called ‘soft proof’ function with which, for example, an RGB file from a camera can be displayed in a CMYK colour space. This so-called soft proof in Adobe Photoshop has some advantages, but also serious disadvantages: Advantages of Photoshop Softproof: A colourful RGB file can be quickly and easily simulated in a usually smaller CMYK colour space For image retouching, for example, the colours that would lie outside the later CMYK colour space can be quickly displayed and visualised so that the retoucher knows …
Picture printing paper
Picture printing paper (or art paper) is a type of paper that is coated on both sides and is very common.
It is available in various grammages, either matt, semi-gloss or glossy coated, and is suitable for all printing processes.
PMS
Pantone Matching System: The proven PANTONE Matching System has been renamed 2010 in “Pantone Plus Series” and supplemented with 224 colors. In 2012, another 336 new colors were added. In 2014 Pantone Plus Series has again been supplemented by a further 84 new colors.
Currently, the Pantone Plus Series has 1755 colors, which are created from 18 Pantone Plus Series base colors.
Press proof
In contrast to a proof, a press proof is created using films or CTP printing plates on special press proof machines with the same colours and parameters as the subsequent production print. Press proofs are rarely used today for cost reasons.
Printing form
The printing form is a central element in the printing process; it contains the image to be printed, i.e. the information that is transferred to paper during the printing process. The type, manufacture and function of the printing form vary depending on the printing process. However, it forms the basis for the reproduction of text and images in print. Four types of printing forms Printing forms can be divided into four main categories, which correspond to the classic printing processes: relief printing, intaglio printing, planographic printing and gravure printing. In …
Printing plate
The printing plate is an important element in printing technology and is mainly used in flat printing such as offset printing. It contains printing and non-printing areas and transfers the printing information to the printing material. This is usually done indirectly, i.e. via a rubber blanket cylinder. The print motif is the correct way round on the printing plate, reversed on the rubber blanket, and the correct way round again on the paper. Modern printing plates are usually made of anodised aluminium with a light-sensitive coating. This coating is directly …
