Accounts Colored paper samples obtained using "Vansan" paints are placed one by one on the measuring device. Each sample is illuminated by a light source for 60 seconds. The measurement results are displayed on the screen and other results in the form of a spectral curve of coefficients using a printer: x y z and color coordinates in the lip colorometric system, the current level is obtained in the form of a table, for example, 2 tables obtained color coordinates X 1 , Y 1 , Z 1 , they are listed based on the modulus and color x, y, z coordinates are calculated. M= X 1 + Y 1 + Z 1 М Z Z М У У М Х Х 1 1 1 The desired points are determined using coordinates x and y on the MKO color chart. Each color is represented as a dot. A polygonal figure is obtained by connecting the points. This is a description of the color gamut. Any point in the polygon can be obtained using "Vansan" series paints. Task: Calculate the values of samples obtained using other "Sigwerk" company paints and evaluate their color coverage. № n/n X Y Z M a b 1 2 Download 0.83 Mb. Do'stlaringiz bilan baham: |
