TW200540663A - 3-D graph determination method for die color combination - Google Patents

Abstract

The present invention provides a 3-D graph determination method for die color combination, which is characterized in comprising, at first, measuring the target color sample and the full density (from low to high) of die color combination by a spectrometer; after measuring the reflectivity of optical spectrum, calculating the value of CIE*a*b, and displaying on a computer monitor using CIE L*a*b 3-D coordinates (CIE stands for Commission Internationale de l'Eclairage). The L*, a*, b* are the three coordinate axes for CIE L* a*b 3-D coordinates (also known as hue space), which are respectively the brightness axis (L*), red/green axis (a*), and yellow-blue axis (b*), and mixed in full density for two neighbored die color combinations on a*b* axes to form a mixed color sample curved surface on CIE L*a*b* 3-D coordinates. The three die color combinations are is formed with three-face mixed color sample curved surfaces as a closed color solid. The four die color combinations are formed with four-face mixed color sample curved surfaces a closed color solid. The monitor is shown with the observed parameters including the coordinate scale, the color sample sphere scale, and the color axis rotation. The computer input interface, such as mouse and keyboard, is used to change the parameters for the coordinate scale, the color sample sphere scale, and the color axis rotation. Thus, the CIE L*a*b value for each color sample will be re-calculated simultaneously to update the display on the monitor.
