Developing ICC Profile Using Gray Level Control In Offset Printing Process
This addresses color consistency issues for offset printing operators, but it is incremental as it builds on existing ICC profile methods.
The paper tackled the problem of inconsistent color reproduction in offset printing by developing an ICC profile based on gray level control, which was used to calibrate a sheet offset printer and achieved satisfactory results in subjective evaluations across different paper qualities.
In prepress department RGB image has to be converted to CMYK image. To control that amount of black, cyan, magenta and yellow has to be controlled by using color separation method. Graycolor separation method is selected to control the amounts of these colors because it increase the quality of printing also. A single printer used for printing the same image on different paper also results in different printed images. To remove this problem a different ICC profile based on gray level control is developedand a sheet offset printer is calibrated using that profile and a subjective evaluation shows satisfactory results for different quality papers.
