    摘要: Density calibration for a printer is achieved using a standard grey scale vignette master and a stored gray scale vignette image that the printer operator can invoke from the operator panel of a printer. The vignette image provides a pre-calibrated scale that is used in conjunction with the □standard□ image to determine the proper optical density. The density is then set by the printer control panel based upon the value obtained by visually matching the two grey scale vignettes.

    摘要: A system for configuring a first printer according to the grayscale printing characteristics of a second printer is described. Grayscale printing characteristics of a first and a second printer are characterized, and a transform between the grayscale printing characteristics of the first printer and the grayscale printing characteristics of the second printer is generated. This transform is used to modify the first printer grayscale commands so as to emulate the grayscale printing characteristics of the second printer.

    摘要: Toner/ink is saved while still being able to print any given color value within the full color gamut of a given printer. Combinations of varying percentages of a printer's toners/inks (cyan, magenta, yellow and black) are determined for maximum black substitution with varying percentages of under color addition (UCA) (e.g., 0%, 50%, 80%, and 100%). Patches of varying combinations of CMYK using maximum black substitution and a given percentage of UCA are printed out, and the color value (L*a*b*) of each patch is measured. Tables are generated having the percentage amounts of C,M,Y, and K and the corresponding measured color value. A first table represents maximum black substitution with 0% UCA. If a desired color value falls within this table, the corresponding CMYK combination represents the most toner/ink that can be saved. If a desired color value does not fall within the first table, subsequent tables representing increasing percentage amounts of UCA are examined. If the color is not found in any of the tables, the requested CMYK is unaltered. When the table is found, the corresponding CMYK combination, found through inversion and interpolation, saves some toner/ink while still being able to print the desired color value contained within that particular color gamut. The method is typically used to build a CMYK-to-CMYK transform table which the printer can use to print multi-color images with the minimum possible toner/ink usage and without sacrificing the image quality.

    摘要: The system, method, and program of this invention is capable of taking as input a three dimensional colorant (e.g., CMY, L*a*b*) and determining an equivalent combination of colors made up of four or more colorants that are used by a given printer. A plurality of patches are printed having predetermined known combinations of varying percentages of three primary colors (e.g., CMY). Another set of patches are printed having predetermined varying percentages of a fourth color (e.g., black). The L*a*b* of these patches are measured. An inversion program is used to determine equivalent CMY component percentage values for the varying percentages of the fourth component based upon similar actually measured L*a*b* values. These determined CMY component percentage values and the known percentages of CMY are used to substitute the fourth colorant (K) for each of the original CMY combinations, known as fourth colorant substitution or black substitution.

    摘要: A unique combination of four colorants (C′M′Y′K′) of a given printer that is equivalent to an externally defined four colorant combination (CMYK) by having the same color values (e.g., L*a*b* values). A fourth colorant, e.g., black, (K) of the externally defined four colorant combination is mapped to an equivalent fourth colorant (K′) of the printer by matching optical density, reflectance, L* or similar color value. The L* value is found for various percentages of the fourth colorant of the printer by printing varying percentages of the fourth component and measuring its L*a*b* values and, assuming a* and b* are near zero, using the L* value. These values are inputted into an interpolation program. Then, patches of varying percentages of each one of the three color components of the printer (CMY) are printed out at varying percentages. The L*a*b* values for each patch are measured and inputted into an inversion/interpolation program along with the corresponding percentages of colorants of each patch. The externally defined four component colorant having L*a*b* values also used in the inversion/interpolation program, which creates a color transform table from CMY with various percentages of K of the externally defined four dimensional colorant to C′M′Y′ with various percentages of K′ of the four dimensional colorant of the printer by matching L*a*b* values.

    摘要: A system, method, and program of the invention determine a unique combination of four colorants (C'M'Y'K') of a given printer that is equivalent to an externally defined four colorant combination (CMYK) by having the same color values (e.g., L*a*b* values). L*a*b* values associated with each three component combination (CMY) with the fourth component value (K) equal to zero of the externally defined four colorant combination (CMYK) are used in an inversion/interpolation program The printer also prints out a matrix of predetermined varying combinations of the three colorants of the printer (CMY)p with the fourth colorant K equal to zero. L*a*b* values are measured for each patched. These values and the corresponding three colorant combination values are inputted into the inversion/interpolation program. For any given externally defined three colorant combination (CMY), or L*a*b* value, a corresponding three colorant combination (C'M'Y') of the printer can be determined from the inversion/interpolation program by matching L*a*b* values. Then, a fourth colorant, e.g., black, (K) of the externally defined four colorant combination is mapped to an equivalent fourth colorant (K') of the printer by matching color values (e.g., L*). For example, the L* value is found for various percentages of the fourth colorant through standard tables where C=0, M=0, Y=0. The L* value is found for various percentages for the fourth colorant of the printer by printing varying percentages of the fourth component and measuring its L*a*b* values and, assuming a* and b* are near zero, using the L* value. As such, the conversion takes place in two steps, from CMY to C'M'Y' and from K to K'.

    摘要: Disclosed is an improved method, in an impact matrix printer, for extending print ribbon life when used in printing bar codes and for improving the quality of bar codes printed by the ribbon, the printer including a dot matrix print head having a plurality of print pins and print hammers. The printer includes a medium to receive printed indicia thereon, and a print ribbon intermediate the print head and the medium, and means for effecting relative movement between the print head, the medium and the print ribbon so as to position opposite the print head different portions of the medium from time to time when the printer is operational and printing and to position different portions of the print ribbon intermediate the print head and the medium at preselected times when the printer is operational and printing. As is shown, the method includes the steps of determining when, under normal operating conditions, the print ribbon should be replaced because of an increase in errors in reading the bar code printed by the printer, for example, the color density of the narrower width lines are too light. Two ways of increasing the density of selected bar code lines of print are disclosed: (1) increasing the number of PELS (Picture Elements) per inch of print in at least selected printed lines of bar code, or (2) impacting the same print lines a greater number of times to increase the color density of at least selected PELS. In this manner, the useful life of the printer ribbon for printing bar codes and the quality of bar codes produced by the ribbon is increased without incurring printer throughput loss.
