Abstract

PURPOSE:To select superior prescription at a high speed without training by interrupting iterative calculation when the density of each dye is not within a prescribed range, or when a color difference from a color sample is greater than a prescribed value in an optional stage of the calculation. CONSTITUTION:When the density of each dye by approximate combination prescription in an optional stage of iterative calculation is not between -5 and 60% o.w.f. for an exhaustion dying method or not between -50 and 600 g//l for a continuous dying method, or when the calculated color difference from a color sample exceeds 15CIE, the iterative calculation for the color smaple with this dye combination is interrupted and calculation for another color sample or with another dye combination is started. The great part of improprer combinations results in the 1st or frequently 2nd or 3rd iterative calculation attains a value other than a reference value, eliminating unnecessary calculation.
