Abstract: A method for forming a color transform for a color printing device having a plurality of colorant channels that includes applying a tone scale adjustment function and a total colorant load limit. An optimization process is used to optimize a merit function including a tone scale reproduction accuracy term and a gamut shape term. The method involves determining an initial merit function value responsive to an initial total colorant load limit and an initial set of tone scale adjustment parameters for a tone scale adjustment function. Modified tone scale adjustment parameters and a modified total colorant load limit are determined that provide an improved merit function value subject to a constraint that an average total colorant load is no more than a predefined threshold for a predefined distribution of input colors.

Abstract: A method for determining color-matching functions includes obtaining spectral data originating from metameric pairs and generating new color matching functions by modifying original color matching functions. The new color matching functions are constrained to be similar to the original color matching functions while reducing calculated perceptual error between the metameric pairs. In another embodiment a method for determining color-matching functions spectral data originating from color matching experiments and from metameric pairs are generated. Color matching functions from a set of parameters and an error function that indicates error due to perceptual differences between the parameterized color matching functions and the color matching experiments are defined. Methods for defining human observer functions, optimizing the definitions of LMS cone response functions as well as other methods and systems are also disclosed.

Abstract: The invention is directed to various calibration techniques for calibrating an imagining device such as a display device, a printer, or a scanner. The techniques may involve characterizing the imaging device with a device model such that an average error between expected outputs determined from the device model and measured outputs of the imaging device is on the order of an expected error, and adjusting image rendering on the imaging device to achieve a target behavior. The invention can achieve a balance between analytical behavior of the imaging device and measured output. In this manner, adjustments to image rendering may be more likely to improve color accuracy and less likely to overcompensate for errors that are expected.

Abstract: Techniques for customer charge accounting in a soft proofing system take into account one or more factors associated with a hard copy proofing job simulated by the soft proofing system. The charge for the soft proofing job can be correlated, at least in part, to the overall cost of the hard copy proofing job emulated by the soft proofing job. The factors use to calculate the customer charge for a soft proofing job may include, for example, comparable hard copy equipment costs, comparable hard copy media costs, hard copy delivery costs, avoidance of delivery and production delays relative to hard copy proofing, and the number of users that view the hard copy proofing job. A value scale factor may be applied to a base cost for a given soft proof, thereby yielding a cost that can be charged to the customer.

Abstract: A system and method for color characterization and transformation obtain color data representing output of a color imaging system, and convert the color data using a color space having a white reference vector that is adjusted during the conversion. The white reference vector can be adjusted according to intensities of the color data being converted. Adjustment of the white reference vector serves to avoid nonuniformities for color imaging systems having different imaging bases, and thereby eliminates, or at least reduces, the amount of empirical adjustment necessary to obtain an acceptable visual match between the color imaging systems.
