    • YD5050 Grating Spectrophotometer Densitometer with 45/0(45 ring-shaped illumination, 0 degree viewing angle), comply to standard  ISO 5-4,CIE No.15. It is suitable for using in ink printing, in Film Processing, Textile Printing and Dyeing, Plastic Electronics and Other Industries for Color Measurement and Quality Control;especially suitable for the measurement and quality control of optical density and dot enlargement in ink printing.

      Under the 45/0 geometric optical illumination and the testing conditions of M O, M 1,M 2 , M 3 stipulated by ISO 13655 standard, the instrument can accurately measure the reflectance data of samples. Under multiple color spaces, it can accurately measure various printing density indexes, color difference formulas and color indexes, and can meet the user's regular testing of various parameters.
