YD5050 Plus Grating Spectrophotometer
OVERVIEW
New model YD5050 Plus 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.
