Abstract: A method for modeling color halftones that reduces both the number of parameters and the number of measurements needed to characterize an inkjet color printer. The method is based on the eigenanalysis of sample reflectance data and a probabilistic analysis that considers light scattering on the paper substrate as a breakage process governed by a log-normal distribution. The method estimates the reflectance of a print color by characterizing colors as a multiplicative composition of primary color reflectances rather than as an additive mixture of primary and secondary color reflectances as suggested by the theory of Neugebaeur.

Abstract: A system and method for detecting edge locations where intercolor bleeding would likely be a problem, and reducing the amount of ink printed at those locations. The method operates on image data including a set of pixels with each pixel having multiple separation values. Upon receipt of the image data, the data is analyzed to identify those pixels located at an edge. A coverage value is computed from the separation values for those pixels identified as being located at an edge. Based on the coverage value, a reduction factor is determined. The reduction factor is used to multiply the separation values for the pixels located at the edge to yield reduced pixel values.

Abstract: Traps are produced at color boundaries in a print page that is present in the form of run-length encoded image data, by way of distance mapping. Distances of the run lengths to an adjacent color are determined without decoding the run lengths into a pixel matrix, and the traps are produced on the basis of the distances thus determined. For this purpose, distance vectors are determined for the starting point and for the end point of a run length. The distance vectors are in each case recalculated from the comparison with the distance vectors of adjacent run lengths. The new values of the distance vectors replace the previous values of the distance vectors if the magnitudes of the distances of the new values are less than the magnitudes of the distances of the previous values.
