  • Establishing a reference printer state using a recursive tone scale matching
    Patent number: 6755498
    Abstract: Method and system for determination of a reference printer state using recursive tone scale matching. The present invention determines the ink values for the primary colorants necessary to produce a desired reference printer state that includes a desired tone reproduction curve and a desired neutral response. The amount of ink for each colorant necessary to produce the desired printer response is initially estimated and then recursively adjusted. Upon each adjustment, a color print is produced with patches of the various combinations of colorants. The actual color of the printed color patches are then determined. If the actual colors match the desired print response, then the process ends and the reference printer state has been determined. If the printer response does not match the desired printer response, then the ink values for the colorants are adjusted and the processes it repeated.
