Standard light source for color matching and calibration method thereof

Abstract

The invention discloses a standard light source for color matching and a calibration method thereof. The method is characterized by comprising the following steps of: (1) setting of x and y standard values of the standard color matching light source: determining the x and y standard values of different models of standard color matching light sources according to a CIE 1931 chromaticity system; (2) color detection: according to a CIE 1931 chromaticity system, recording standard color matching fluorescent tubes of different models are detected, and values of color parameters x and y of each tube; and (3) matching: matching the fluorescent lamp tubes higher than the standard value with the fluorescent lamp tubes lower than the standard value to obtain the standard light source for color matching, wherein the x and y values of the standard light source for color matching are + / -0.0012 of the standard value. The color matching standard light source with complete consistency provided by the invention solves the problem that different existing manufacturers use different light-emitting lamp tubes so that provided standard color matching light boxes are different in colors. Based on the provided color matching standard light source, producers, users and clients are enabled to obtain completely same color display based on the color matching standard light source provided by the invention, and color deviation of products caused by color difference of the color matching standard light source among different users is avoided.

Description

technical field [0001] The invention relates to a test method, in particular to a standard light source for color matching and a calibration method thereof. [0002] Unless otherwise specified: the standard lamp tubes and standard color matching lamp tubes described in the present invention are all fluorescent lamp tubes conforming to the standards of the International Commission on Illumination (CIE). Background technique [0003] All kinds of monitors can’t meet the requirement of color uniformity even after being calibrated by precision instruments; the same pattern document will show different colors on different monitors, after the colorist (according to the color of his own monitor) colors the pattern document, At this time, the color of the pattern document has actually changed; when the work order is sent to the manufacturer, the manufacturer cannot correctly determine whether the color is the real requirement of the previous customer, and the produced product will h...

Problems solved by technology

Therefore, the so-called standard color-matching light boxes currently on the market cannot complete color transmission and color discrimination.

[0009] The reasons for the analysis are: (1) The D65 standard color-matching light boxes of different standard color-matching light box manufacturers use D65 standard color-matching fluorescent tubes, which come from different lamp tube manufacturers, and different lamp tube manufacturers use their own Fluorescent tubes are produced with different color standards, therefore, resulting in large differences in the colors displayed by fluorescent tubes of opposite colors

(2) During the production of the same batch of fluorescent tubes, due to the complexity of the manufacturing process, it is difficult for the lamp manufacturer to ensure the consistency of the color of the lamp tubes, and the difference in the color of the lamp tubes between different batches of lamp tubes is even greater

[0010] Based on this, the present invention aims to solve the problem of inconsistent color display of the existing standard light source for color matching
