The shift to M1 Measurement is a fundamental requirement for any workflow aligned with modern ISO standards. Relying on M0 or M2 readings for OBA-containing papers leads to serious inaccuracies and color discrepancies between the proof and the final print. All modern spectrophotometers must be M1 compliant to ensure data integrity.

M1 assists production managers in avoiding unnecessary press adjustments by measuring the full chromatic impact, including fluorescence. This method not only helps calculate accurate Total Ink Coverage (TIC) limits but also ensures that quality control data accurately reflects what the human eye perceives in a calibrated viewing environment.
