摘要： A method of generating artifact-free threshold matrices for digital printing devices is provided. The method includes, for example, the steps of establishing a threshold matrix by examining at least one color level for artifacts and removing the color level from the threshold matrix if it has artifacts. The method further includes the steps of examining a range of color levels for artifacts and removing the color levels from the threshold matrix which have artifacts and evenly distributing the remaining color levels over a range of color levels from a first color level to a last color. The examination of color levels for artifacts may be implemented manually or through an automated computer controlled process. The automated process includes digitally acquiring the color level and performing a Fourier transform on the color level to determine its spectral components. The spectral components are analyzed to determine the presence or absence of artifacts. Color levels having artifacts may be removed from a threshold matrix via one of several removal procedures. Once the threshold matrix is defined by artifact-free color levels, it is then integrated or stored into a printer or display device.

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： There is provided an improved method for laminating the components of a tiled display such as an AMLCD tiled display. In conventional laminating processes, forces are applied to the two parallel glass plates (i.e., the cover and back plates) separated by a liquid adhesive film. The two plates are squeezed together over their entire area forcing liquid laterally out from between the glass plates and tiles until the desired spacing or gap (filled with liquid adhesive) between the cover and back plates and the tiles is obtained. However, this process may require several hours to complete for large panels and, in addition the process is susceptible to trapping air bubbles in the adhesive. Consequently, the traditional process is not well suited for the mass production of large panels. The “pseudo” rolling-like lamination process of the present invention replaces the traditional lamination process and requires significantly less time.

摘要： A system, method, and program for generating a color rendering dictionary file or look-up table for an equivalent device dependent four component colorant combination for a given printer from a given device independent three dimensional color space. First input parameters are comprised of varying percentage amounts of an additional fourth colorant and corresponding measured color values for varied percentage amounts of the additional fourth colorant. Second input parameters are comprised of varying percentage amounts of three base colorants and corresponding measured color values for varied percentage amounts of the three base colorants. Percentage amounts of the three base colorants (three colorant values) for each varied percentage amount of the additional fourth colorant are determined from the sets of measured color values. The percentage amounts of the three base colorants with the additional fourth colorants are determined, such that the fourth colorants are equivalent to the varied percentage amounts of the base colorants. The determined four colorant values are then correlated with the measured color values of each of the equivalent varied amounts of the three base colorants. A look-up or color dictionary is used to find correlated four colorant values for any given color.

摘要： A line printer has a print head with plural nozzles arranged in a single row generally transverse to the direction of relative motion of the print head and a print medium. The nozzles are spaced plural dot positions from each other corresponding to a plural dot segment of a single dot matrix character stroke. When the row of nozzles is slanted relative to the direction of motion, drops from the nozzles are used to print stroke segments in plural character strokes simultaneously.

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'.
