Scoring method for color quality of light beam laser paper

Abstract

The invention relates to a scoring method for the color quality of light beam laser paper. The method includes the steps of: adopting a color measurement automatic detection system, and during measurement, enabling a light beam direction of light beam laser paper to be vertical to a horizontal direction of a measuring platform; setting an interval of adjacent measuring points of a color measuring instrument in the horizontal direction of the measuring platform, the number of the measuring points, and the line spacing and line number in a vertical direction; reading color information of a sample to be measured in different positions; measuring chromatic values of a standard sample and a test sample respectively, and adjusting data obtained by measurement to a same period position vertical to a light beam to calculate and compare in one-to-one correspondence; making statistics of calculated values of chromatism according to the law of three aspects of being smaller than small chromatic aberration, being larger than a chromatic aberration tolerance and different chromatic aberration interval distribution; and adopting different weighted weights to calculate a comparative score of the standard sample and the test sample, thereby judging whether the test sample is qualified. The scoring method for the color quality of the light beam laser paper positions all samples to be measured to a corresponding position of light beam laser paper in a unified manner to perform sampling and comparison, thereby improving the measuring accuracy.

Description

technical field [0001] The invention relates to a method for scoring the color quality of light column laser paper. Fix the position of the color measuring instrument and the paper to be tested through the color measurement platform, set the number of sampling points and the sampling interval in the operating system, and control the measuring head to collect the chromaticity values ​​of the standard sample and the test sample respectively; the collected standard sample Adjust the chromaticity value of the test sample to the same cycle position to compare and calculate the color difference; according to the color difference tolerance set by the user, the comprehensive comparison score between the light column laser paper standard sample and the test sample can be calculated through this scoring method, thus giving Judgment of whether the test sample is qualified or not. At the same time, this method can also collect the color chromaticity values ​​at different positions of a s...

Problems solved by technology

But the existing method will have artificial measurement and operation errors (the position of the instrument and the paper is different, the measurement results will be very different); at the fixed position of collection, if the positions of the standard sample and the test sample cannot be completely corresponding, The calculated color difference cannot accurately reflect the quality of the actual test paper

At the same time, by measuring one point or several points at a fixed position, the evaluation of whether the paper is qualified can not reflect the quality of the paper, and it has a certain one-sidedness.
