Gloss describes the quality of a surface to reflect light directionally. If light falls on a paper at an angle of 75 degrees, then a very matt uncoated paper will not reflect the light in a directional way, but very diffusely, whereas a high-gloss paper will reflect much more light in the opposite 75 degree angle in a directional way than it will reflect light diffusely. The more reflective the surface, the greater the gloss.
To measure colour and gloss, X-Rite and other companies offer numerous glossmeters, which often emit light at different angles and can then measure the direction. A very good introduction to the subject in English is a series of videos from the American company Technodyne, which manufactures glossmeters for the paper industry.

MYIRO-9: New Spectrophotometer from KonicaMinolta in action
Over the last few months, we at Proof.de have been thinking about further improving our already very good colour measurement technology in terms of speed and measurement precision. Relatively quickly it became clear that only two devices would come into question: The KonicaMinolta MYIRO-9, the successor of the former FD-9, or the X-Rite ISIS 2 XL. The starting point: Since we at Proof GmbH have 5 proofing devices, the calibration of targets for profile optimisation is a time-critical undertaking for us. Therefore, we had been looking around for an upgrade of … read more

New PANTONE Formula Guides with incorrect ink formulations
Several errors have crept into the new PANTONE 2023 fan decks. In both the PANTONE Solid Coated and the Solid Uncoated color fans, there are colours for which the new ink formulations are incorrect.

We passed the first proof certification for the 7C proof under FOGRA55
A few days ago Proof GmbH was the first company to be certified for proofing for the new 7C exchange colour space FOGRA55. Fogra has developed characterisation data for extended multicolour printing with the printing colours CMYKOGV – i.e. cyan, magenta, yellow, black (contrast), orange, green and violet – FOGRA55 as part of a research project over the past few years. The characterisation data and the ICC profile Ref-ECG-CMYKOGV_FOGRA55_TAC300.icc have been published on the Fogra website in recent weeks. We have now carried out the certification via GMG ColorProof, as … read more
