I have a question regarding Colormanagement.
1. I use GMG Colorproof and create a proofing that according to Fogra 39 and measured the Mediawedge with GMG Proof Control my proof is passed.
2. I optimized my offset press (with 175 lpi) according to the ISO 12647-2. My Inks are ISO 2846-1, the CtP are compensated and the dot gain result are within tolerance.
3. Measured the Mediawedge with UPPCT, only the paper white that failed, the rest are passed to the ISO 12647-2
4. I can match under the D50 condition during production but after that under different light condition they are visually not match. The press result lost the red color cast.
