METHOD OF MAT TINT FORMULA CALCULATION Russian patent published in 2008 - IPC G01J3/46 

FIELD: physics.

SUBSTANCE: methods of formula calculation of mat, polished, pure tints used to evaluate proportion of flatting agents in formula without necessity to perform actual calculation of composition formula based on common spectrophotometric characteristics of mat sample using standardised measurement geometry 45°/0° in combination with established gloss measurement, or, alternatively using spectrophotometer provided with geometry measurement d/8° and analysing indications taken with included and excluded reflecting component.

EFFECT: precise results without additional tinting stages.
