Pantone

Pantone is the creator of the Pantone Matching System and Pantone Plus Series, worldwide color systems for spot colors 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.

The Pantone Plus Series includes since 2014 1755 “Pantone +” colors, mixed from 18 basic colors.

In printing and proofing area following variants are important:

Pantone Solid Coated for coated paper
Pantone Solid Uncoated for uncoated paper
Pantone Pastels and Neons Coated and Uncoated
Pantone Metallics and Pantone Premium Metallics for Coated Paper

PDFX-ready

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.

PDFX-ready creates guidelines, instruction sheets (called recipies), application settings (colour, pdf export) and preflight profiles. The PDFX-ready specifications are based on the PDF/X-Plus specifications of the Ghent (PDF) Workgroup.

Of particular note is the 2015 updated Guidelines for creating PDF / X-4 files, which can be downloaded from the website of the Swiss initiative.

Picture printing paper

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.

Picture printing paper is mainly used for flyers, brochures, posters, business cards and the like.

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 the proof, a press proof is created using films or CTP printing plates on special press proofing machines with the same colours and parameters as the subsequent production run.

A press proof is very precise in terms of colour and, due to the edition paper used, is almost identical to the later print. Compared to the classic proof, however, a press proof is usually tens of times more expensive and quickly costs several hundred euros. Moreover, a press proof needs much more time for the production.  Therefore, it is hardly relevant today for economic reasons and is only used for very delicate prints with high print runs.

Process colours

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.

Proof

What is a proof?

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. Today, it is almost exclusively calculated using a RIP and then produced with inkjet printers on special proof papers.

The proof data is converted into separations, then reassembled into a composite image to correctly simulate overprinting and trapping. The data is then transferred as a newly created composite image to an inkjet printer, usually with more than 8 colours, which prints the data. In addition to the print data, a proof must also carry a UGRA/Fogra media wedge in order to be colour-consistent and legally binding. Thanks to the standardised wedge, the printer is able to check the proof for correctness. Since many printing companies do not have this measuring technique at hand, the proof is often provided directly with a test report that shows the correctness of the measured values of the media wedge directly on the proof.

Earlier methods such as Chromalin etc. are no longer available on the market today.

In addition to the term “proof”, terms such as colour proof or digital proof are also commonly used.

ISO 12647 defines the term “Validation Print” (ISO 12647-8) in addition to the highest standard of contract proof, “Proof” (ISO 12647-7). The Validation Print is characterized by the fact that although it is less accurate in colour, it can also be produced on laser printers. Compared to the contract proof, however, it accepts much higher colour deviations and is only legally binding after prior consultation. A real “proof”, i.e. a real contract proof according to ISO 12647-7 is currently not only by far the best variant in terms of colour, but also the only legally binding proof.

proof

To “proof” means to produce a proof or have a proof produced. “I still need to proof the brochure” is the typical phrase for the word “to proof”.

Proofing thus means to have a colour and legally binding proof produced according to the current ISO 12647-7 standard. The current valid revision of this standard is ISO 12647-7:2016, which regulates the central parameters for “proofing” such as target tolerances and specifications for producing the proof, the job tickets and the test report.

Only when an UGRA/Fogra or, for the American proofing standards, an IDEAlliance media wedge is printed does the proof become a proof, i.e. the proofing process differs from the printing process. This media wedge does not have to be measured, but it is of course helpful for the printing company if it does not have to measure first but can see at first glance that the proof has been produced in colour and legally binding according to the current standard.

Proof cheap

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 PANTONE and HKS.

Such certified proofs can be ordered at shop.proof.de for all proof profiles.

But what makes a certified proof cheap? Well, the low price. Proofs are printed on certified proof papers on very high-quality pigment inkjet printers using mostly expensive proof software and measured with spectrophotometers. So how can you produce cheaply here?

You can find further information on the subject of cheap proofs here.

Proof costs

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. Whether different motifs or one motif is proofed several times is usually irrelevant. 30 proofs of one page each cost the same as a proof of 30 different pages each, because for the proof shops the RIP time is not decisive for the costs, but rather the ink and paper on which the proofs are printed.

Serious suppliers proof exclusively with original inks and Fora-certified proof papers, which also have a good strength of around 250gr/sqm for picture printing papers, and around 150gr/sqm for uncoated papers. By using non-certified papers of lower grammage and especially by using cheap compatible inks and printing systems, some service providers offer cheap proofs, but these can cause problems due to the inferior materials. Non-certified proofing substrates, for example, have not provided proof of durability in terms of mechanical aging; alternative cheap inks sometimes lead to uncontrollable metamerism effects.

In some cases, printing companies in particular also offer a “proof” that they produce in-house without media wedge evaluation. We personally know a printing company whose “proofing device” has not been recalibrated since 2003. The quality of such ” coloured prints” is perhaps decent, but such a print can of course never reach the precision of a “contract proof” according to “ISO 12647-7:2016”.

In 2016, ISO 12647-7 was updated, and with the appearance of a new standard, i.e. ISO q12647-7:2016, the previous standard is automatically cancelled. However, many suppliers do not keep their software up to date, and therefore produce “proofs” according to “ISO 12647-7”, but not according to the latest version of the standard. These proofs do not conform to the standard, and are therefore not colour and legally binding. For end users and buyers, however, these details are difficult to oversee.

The FOGRA certification helps here: whoever has a current and valid Fogra certification must prove that they have colour and legally binding proofs according to the latest standard. And because the certification is only valid for one year, a new certification, again valid according to current criteria, must be issued after one year at the latest. The companies that save themselves the trouble of obtaining such a certification usually have good reasons for doing so.

PSD

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.

Under the PSD certification criteria process control output, color stability and the correct processing of PDF-X data and color profiles are checked.

PSO

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.

The following standards are summarized in PSO – “ProcessStandard Offset Printing:

ISO 00005-4: Optical density
ISO 02846-1: Printing inks
ISO 03664: Standard Lighting
ISO 12218: Platesetting analog
ISO 12641: Scanner Testchart
ISO 12642: Output test charts
ISO 12646: Monitors
ISO 12647-2: standard pressure
ISO 12647-7: Digital Proof
ISO 13655: Spectral color measurement
ISO 13656: Densitometric and colorimetric measurement
ISO 14981: Densitometer

 

PSR

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.

As the printing industry is in a constant state of change, the PSR_V2 standards were revised in 2019 to reflect the new paper colouring and measuring conditions:
