Abstract:
1. A method of providing color matching between a color proof output device and a printing press comprising inputting color bar data, said color bar data showing gradients of cyan, magenta, yellow and black dots and said color bar data having been corrected so as to match gradation of said color proof output device to gradation of said printing press, into said color proof output device and making said color proof output device output said data to produce an output result, inputting color bar data, said color bar data showing gradients of cyan, magenta, yellow and black dots and said color bar data having its gradation not corrected, into said printing press and making said printing press output said data to produce an output result, measuring colors of said output results by a colorimeter to produce measured results, and color matching between said color proof output device and said printing press based upon said measured results.
