Proofs for recycled paper. Is that possible?
We produce proofs for classic white uncoated papers on a daily basis, but the question often arises as to which proof standard could be used for printing on recycled paper. In general, the paper white in a proof is precisely defined in the proof standard and is also measured in every test report. For PSOUncoated it is 95.00 / 0.00 / -2.00 in CIELAB and for PSOUncoatedV3 it is 93.50 / 2.50 / -10.00, i.e. slightly darker (93.50 instead of 95.00 for brightness L) and significantly bluer (-10.00 instead of …
