To ensure secure data exchange between customers and proofing service providers, fonts must be embedded, converted into paths or rasterized. This ensures that it is and remains exactly the same font and exactly the same style.
How do I do that?
Every print shop in Germany adheres to a predefined standard, the process standard offset printing. This standard defines target and tolerance values for printed products. In order to prove that your proof delivered to the print shop meets these standards or is within the tolerances, the media wedge is measured and the values analysed in case of doubt – i.e. in case of a streak. If these measured values are correct, the print shop is obliged to adhere to and achieve these values.
Practice generally shows the following: If you want to have a 4-page image brochure proofed and printed, it is usually sufficient to have a single media wedge printed under the 4 pages. If the media wedge is also provided with a test report, the colour accuracy for the print shop is directly confirmed as a guideline.
However, if you want to be on the safe side, have a separate media wedge (including test report) printed under each of the 4 pages of your brochure.
A proof is prepared according to the currently valid ISO standard 12647-7 and is legally binding with a UGRA-Fogra media wedge and measurement report.
How does this check work?
If you need a proof with UGRA/Fogra Media Wedge CMYK V3.0, there are two ways to add the test report to your data.
What is the advantage of automated creation and checking of the media wedge directly in the proofing device?
Further information on the test report, the media wedge and on the work and responsibility of UGRA/Fogra can be found at www.ugra.ch and www.fogra.org.
Very simple: A proof is the simulation of a later print, either as soft proof on the monitor or as contract proof, validation print or as form proof on paper.
Softproof: A softproof is the color-accurate representation of the print on a monitor. This can be done either at the agency or directly at the printing machine, for example, so that the printer can coordinate the production run with the soft proof.
Contract Proof: The “highest” level of proofing: A contract proof is a very high-quality simulation of the subsequent printing result, and is nowadays actually always produced with special inkjet printers on special paper with special software. The UGRA/Fogra media wedge print makes the proof “colour and legally binding”. In the best case, the media wedge is checked directly during proof production with a measuring device and a test report is glued or printed on which confirms compliance with the tolerances.
Validation Print: A Validation Print has higher tolerances regarding the color deviations from the given standard than a contract proof. It is therefore not “colour and legally binding”, i.e. it does not serve as a contract or “contract” between the designer and the printer, unless both parties have agreed that Validation Print can serve as a colour reference. Validation prints are often used in the coordination process in agencies or as quick templates with good colour matching, as they can also be produced on current laser and LED or other digital printers. Compared to inkjet printing, these printing systems are many times faster and cheaper.
Form Proof: A form proof is often found in print shops; large sheets of paper on which the finished imposed sheets, e.g. of a magazine, are printed. Form proofs are printed with inexpensive inkjet plotters on inexpensive paper and usually look terribly coarse and pixelated, even the colors are terrible. However, the data for the form proof runs through the same workflow with which the printing plates are later produced. This means that what can be seen on the form proof can later also be seen on the printing plate. Thus, the final printing forms can be optimally checked once again to ensure that all fonts, images and embedded graphics are displayed correctly. However, a form proof is by no means binding in terms of colour.
