Abstract
The contact screen includes preprocessing step for converting the continuous level image into a pulse-width modulated binary image. The process is limited by the fact that no practical recording medium has hard-clipping characteristics. An algorithm for the precompensation design model is presented herein and is thereafter used to actually fabricate a precompensated nonlinear contact screen corresponding to low-gamma 4127 Kodak commercial film. The performance of the realized screen effectively demonstrates the usefulness of the algorithm.
