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.
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.
Pantone is the creator of the Pantone Matching System and Pantone Plus Series, worldwide colour systems for spot colours that have widespread use in graphics and printing industry, but also in the field of plastics and textile. The “Pantone Matching System” has been renamed “Pantone Plus Series” in 2010.
PDFX-ready is a Swiss initiative founded in 2005. The goal is to promote and facilitate the use of the PDF/X ISO Standards for the exchange of printing data.
Picture printing paper (or: art printing paper) is a double-sided coated paper grade which is very widespread.
It is available in various grammages, coatings (matte, satin or glossy coated) and is suitable for all printing processes.
The paper surface hardly absorbs any printing ink and can reproduce colours and contrasts very accurately. For this reason, picture printing paper is particularly suitable for printing pictures.
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.
Ein Andruck wird im Gegensatz zum Proof mittels Filmen oder CTP Druckplatten an speziellen Andruckmaschinen mit denselben Farben und Parametern wie der spätere Fortdruck erstellt. Aus Kostengründen werden Andrucke heute kaum mehr verwendet.
Process colours are the colours that are created in printing when several colours are printed on top of each other (usually using halftone screening).
In four-colour printing, this colour is composed of cyan, magenta, yellow and black. With these four colours a very large number of colours with different tonal values can be printed.
To “proof” means to produce a proof or have a proof produced.
A proof (correct: contract proof) is an ISO-certified testing device for the graphic arts industry. A proof simulates the colourfulness of offset or gravure printing in a colour and legally binding manner within the narrow tolerances of ISO 12647-7.
Proof cheap is a typical search term that people use in search engines to search for a cheap, colour and legally binding proof. But what makes a cheap proof? A proof becomes a proof that it is produced according to the specifications of the latest revision of the proofing standard ISO 12467-7 and that it is within the tolerances of this standard. The current revision is ISO 12647-7:2016, which has been tightened even further with this standard and has been supplemented by a certified edition of spot colours such as …
The proof costs, i.e. the costs for a proof, are usually calculated according to the format to be proofed and the quantity of proofs.
PSD is “Process Standard Digital Printing” by the Fogra as PSO stands for for “Process Standard Offset”.
Process Standard Digital Printing certified companies operate mainly in the field of small-scale or large-format digital printing. The certification is valid for two years and then must be re-certified.
PSO stands for “ProcessStandard Offset Printing”, a standard that was developed by Fogra and the German Printing and Media Industry together. The ProcessStandard Offset Printing is a set of standards for offset printing. With test equipment and control by measurments as described in the PSO, the printing process of the data delivery and data preparation on the platemaking is monitored, controlled and checked.
PSR stands for “Process Standard Rotogravure”, a standard provided by Fogra, ECI and the German Printing and Media Industries Federation (bvdm).
The Process Standard Rotogravure is a standard developed for gravure printing.
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” is one of four rendering intents in gamut mapping.
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 stands for red, green and blue. Human colour vision is based on these colours.
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.
