A proof for coated papers with optical brighteners, we offer on semi matte EFI 8245 OBA semimatte with 245 gr / sqm. The EFI Proof Paper 8245OBA Semimatte has been specifically designed for proofing white and brightened, coated papers. The white point of this semi matte paper is very close to the values of the FOGRA51 profile and thus allows proofing of FOGRA51 with virtually no paper white simulation at all. It is also well suited for simulating paper conditions PC1 according to ISO 12647-2:-2013.

With the new SpectroProofer ILS30 made by X-Rite, Proof GmbH has created the basis for automated measurements and Proof verifications according to M1 standard. Proofs with optical brighteners (OBAs – Optical Brightning Agents) can now be measured. Contrary to earlier announcements, the new SpectroProofer are also able to measure the current proofing standards as before in M0 measurement standard.
