Open the CIPO recordAbstract From the Canadian patent
A color photography printing process prints a test print on the basis of color intensities of three color ranges transmitted through a small selected area of a test print. The exposure times for the three ranges are recorded besides the print in machine readable code. In the making of the final print the machine readable code controls the printing time. The times determined by the machine readable code may be corrected during the making of the final print by corrections determined by an expert observer of the test print.
