During Print ’05 in Chicago ColorMetrix shared a booth with AbsoluteProof, who also invited Pierre Ferland from The Whole Proof. The Whole Proof has developed an innovative new technology which allows virtually any printing paper to be specially coated and then utilized on an inkjet printer for proofing purposes. In last week’s Golden Nugget I discussed the importance of gloss being the same for two printed samples to appear the same. What I found interesting when I requested “bullet points” from Pierre to prepare this week’s e-mail is that he addressed gloss better than I could have while explaining the importance of his product. So, the rest of this week’s e-mail is provided by >Pierre Ferland of The Whole Proof (pierre@twproof.com)
For the cup manufacturer’s story: They were proofing on Epson matte heavyweight paper, but the characteristics of that paper were not consistent with what they were using on the press. The branded inkjet paper was much brighter and smoother than the food grade SBS that they were printing on. When they tried to emulate the SBS’s brightness using the plotter’s ink, it made the paper glossy (typical with pigment-based inks). Even if that hadn’t been the case, very smooth paper reflects light more directly than “fuzzy” paper, which diffuses light. The print buyer and pressman were getting proofs that were much more vibrant than what could actually be accomplished on the “beverage cup” SBS using a flexographic press. Proofing on the same paper they use on the press not only gives their pressman a more realistic target, but it also allows them to set the right expectations with the print buyer, and supply fully functional, full color prototypes made from the actual press stock the whole proof, and nothing but the proof! – Pierre Ferland (TWP International)
