Shortly before Christmas, we initiated a major shop update, and adapted and improved numerous detail functions. But we are especially pleased that the update went without any major disruption for our customers, and that the shop was online and accessible for only a few hours, even though the update had to be carried out at the live shop. The most important point for us was to update the upload area. The new file upload can now process up to 2GB per file and up to 50 files per article and:  … read more

The Proof GmbH provides proofs for Scheufelen Heaven 42 papers on the new EFI 8245 OBA proofing paper. With this new proofing paper it is now possible to proof the bright-white paper dye of Heaven42l. With Heaven 42 a bright white paper was developed by the German paper company Scheufelen, which opened up a new color whiteness. Especially technical motifs (shades of gray, silver tones from 4c, strong contrasts) act on Heaven 42 particularly brilliant and neutral. With an unchanged separation (eg with ICC profile “ISOcoated_v2”), but the printed image with the  … read more

“We print 135gr/sqm on a Berberich Allegro. Can you make us a proof on this paper? Can you proof on our final production paper?” Our telephone support often asks for a proof on production paper. Unfortunately, we always have to answer the question negatively. I would like to briefly explain the reasons for this in the following article. Proofing on production paper is still technically impossible. All proofing systems currently certified by Fogra are based on an inkjet printer as a test printer, mostly from Epson, Canon or HP. These  … read more

EAN codes are standard on every product today. While in the good old days, shopowners themselves typed the prices into a cash register by hand, today scanner cash registers are the rule, which scan standardized EAN codes with a laser and thus clearly recognize the article and add it to the receipt. EAN, by the way, stands for “European Article Number” and was replaced in 2009 by the global GTIN, “Global Trade Item Number”. The EAN or GTIN is a barcode that can be read automatically and read by barcode  … read more

Customers are often unsettled when they hold a proof in their hands. “The proof of the picture is much darker than the picture on my monitor. Why is that so? And what do I do now?” There are many possible reasons for a deviation between the proof and, for example, the monitor display: The monitor is not calibrated Only calibrated monitors can accurately display color. When I buy a cheap monitor and connect it to my computer, I definitely can’t see any real color. As a rule of thumb, only  … read more

Requests such as the proof of a printed tin can often reach us. Why can’t such a printed can be “proofed”? A proof is a standardized product. Take the classic ISOCoatedV2 proof, for example; the standard proof for coated printing paper. Here is the definition in brief: “Paper type 1 and 2, glossy and matt coated paper, dot gain curves A (CMY) and B (K) from ISO 12647-2:2004” (Source: farbproofs.de) Metal is printed with a varnish. Neither the colour of the metal of the tin can nor the colour of  … read more

Proofing service providers are often asked the question: “I have to have a proof done, but I don’t know for which profile. Can I also have a proof made without a profile?” Proofs are standardized products that are created and tested according to a certain set of values. This is exactly the point that distinguishes them from any “colourful printouts”. Specifically: A proof for coated printing paper is produced according to the standard values of ISOCoated V2 (paper type 1 and 2, glossy and matt coated image printing, dot gain  … read more
