Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back The ability to use the colorimeter with the RGB components for research photooptical bleaching, toning and dyeing the paper E.E. MAIOROV, T.A. CHERNYAK, A.V. DAGAEV, A.Ch. MASHEK, G.A. TSYGANKOVA, M.V. KHOKHLOVA, A.V. KURLOV, A.O. FADEEV In the present article the relevance and importance of the use of the colorimeter with the RGB components for the study photooptical bleaching, toning and dyeing the paper are showed. The operation of the device and shows the advantage over existing sensors, making the device promising in industrial colour control is described. The analysis of the impact photooptical bleaching, toning and coloring paper to color coordinates X, Y, Z and brightness B is conducted. The errors of the color parameters X, Y, Z is not worse than 0,3% and the interpolation of the brightness B of the paper is not worse than 1 % are received. The dependences of the coordinates X, Y, Z the concentration of the dye-painted paper, which was almost equal to the reference data of the spectrophotometer Datacolor 500 ΔX, ΔY, ΔZ of 0,7 % are presented. Keywords: colorimeter, spectrophotometer, reference value color coordinate, brightness, interpolation. Contacts: E-mail: majorov_ee@mail.ru Pp. 22-29.
