Abstract

The invention relates to a gray value testing system based on a computer, which comprises a light path part and a light detection part, wherein the light path part comprises a light source, a Kohler illumination system and an integrating sphere; the light detection part comprises a color sensor, a circuit board, a computer and a display interface; the light source, the Kohler illumination system and an incident hole of the integrating sphere are arranged on the same straight line, the color sensor is placed on a receiving hole of the integrating sphere and connected with the circuit board in the light path part, the circuit board is connected with the computer and the computer is connected with the display interface; light emitted by the light source can be changed into a parallel light beam after passing through the Kohler illumination system in the light path part, the integrating sphere in the light path part can better eliminate the influence of incident light and outside stray light to the color density measurement values; and an information processing module can greatly improve the density detection accuracy by adopting a numerical value fitting system. The system has the advantages of high testing accuracy, high speed and lower cost.

Description

technical field [0001] The invention relates to a gray value testing system based on a computer, which can detect the density value of printed matter in real time. Background technique [0002] The optical path of the existing gray value testing equipment consists of: tungsten-halogen light source, infrared filter, lens, slit, reflector, grating, lens, and slit. The gray value measuring equipment is complex in structure and expensive, and many foreign gray value measuring equipment have certain differences in the hardware of each test equipment, so even the gray value testing equipment of the same manufacturer will have certain differences when measuring. There are differences, there are differences. [0003] In order to overcome the above disadvantages, the present invention is based on a computer to test the gray value by fitting with the standard gray value, the test accuracy is high, and there will be no error between the test results caused by the different hardware be...
