摘要： After determining a CMYK-to-Lab relationship, a Lab lattice-to-CMYK relationship is determined. The Lab lattice-to-CMYK relationship defines, for each Lab lattice point, a plurality of allowable CMYK data sets. Then, for each Lab lattice point, several allowable CMYK data sets with the largest K value are first selected among the plurality of CMYK data sets. Then, one CMYK data set with the smallest color distance from the subject Lab lattice point is selected among the several allowable CMYK data sets. If the subject Lab lattice point falls within the color reproducible range for the value of K of the selected CMYK data set, the selected CMYK data set is finally determined for the subject Lab lattice point. It is possible to create a lookup table, in which each Lab lattice point falls within the color range of the K value in the corresponding CMYK data set.

摘要： In a halftone module, it is judged whether or not the value “rate” for each pixel is greater than zero (0). In other words, it is judged whether or not the eight-bit input data Iin of each pixel is around a half of the relative density value for a small dot of a corresponding color. If the eight-bit input data Iin of the subject pixel is near to a half of the relative density value for a small dot, noise is added to the threshold values Ta, Tb, and Tc. The noise-added threshold values Ta′, Tb′, and Tc′ are used in the comparing process.
摘要翻译：在半色调模块中，判断每个像素的值“rate”是否大于零（0）。换句话说，判断每个像素的8位输入数据Iin是否是相应颜色的小点的相对密度值的一半左右。如果对象像素的八位输入数据Iin接近小点的相对密度值的一半，则将噪声加到阈值Ta，Tb和Tc上。在比较处理中使用噪声相加阈值Ta'，Tb'和Tc'。

摘要： For each paper type, a plurality of two-dimensional excitation characteristics tables Ti are provided in one to one correspondence with a plurality of colors i. The excitation characteristics table Ti for each color i contains a plurality of sets of excitation-reflectance data Bi (λ0, λ) in a two-dimensional matrix form, for a plurality of combinations of incident light wavelengths λ and reflected light wavelengths λ0. The excitation-reflectance data Bi (λ0, λ) indicates the ratio of the amount of the reflected light wavelength λ0 generated in response to incidence of the incident light wavelength λ, with respect to the amount of the incident light wavelength λ. Using the two-dimensional excitation characteristics table Ti corresponding to the user's selected paper type and using the spectral radiation characteristics S(λ) of the user's selected light source type, Equations (9)-(11) are calculated to create an output profile, and color conversion is performed by using the output profile.

摘要： A plurality of color signals indicative of a plurality of color patterns are processed based on a first distribution curve to distribute the original color signals into color signals for normal ink and color signals for light ink. Then, the plurality of color patterns are printed by the color signals for normal ink and color signals for light ink. Then, the density of each color pattern is detected to produce a density curve. A second distribution curve is produced based on the detected density, the original color signals, and the first distribution curve so that the second distribution curve can attain a properly linearly-changing density curve. By preparing beforehand a plurality of first distribution curves dependently on a variety of usage conditions of the printer, it is possible to use a second distribution curve that is in conformity to the usage condition, under which the printer is desired to be driven, by selecting a distribution curve that corresponds to the usage condition.

摘要： An error utilization factor line, indicative of a relationship between the amount of the error utilization factor K and input data for a present pixel, is determined dependently on characteristics of the image, on the value of the threshold, on the size of the distribution matrix, or on the condition of the recording operation. The amount of the error utilization factor K is determined dependently on the input data of the present pixel and based on the error utilization factor line. The correction amount F, collected from the already-processed nearby pixel, is multiplied by the error utilization factor K, before being added to the input data of the present pixel for the halftone process.

摘要： When the input value becomes close to the medium dot relative density value (Den_M), the large dot threshold value (Thre_L) and medium dot threshold value (Thre_M) become close to each other. It is possible to prevent output values from being converged to the particular medium-dot output value. When the input value becomes close to the small dot relative density value (Den_S), the medium dot threshold value (Thre_M) and the small dot relative density value (Den_S) become close to each other. It is possible to prevent output values from being converged to the particular small-dot output value.

摘要： Of the four basic colors of cyan, magenta, yellow, and black, each of two basic colors of cyan and magenta is expressed by two different inks, that is, light ink and normal ink which have different densities for the corresponding color. For each of the basic colors of cyan and magenta, after tone correction is performed in S2 (S108) to attain a linear input/output characteristic, an optimum group of conversion tables T3 that matches the user's selected set of printer characteristic is selected in S110 from the plurality of groups of conversion tables T3, which have been prepared in advance in correspondence with a plurality of sets of printer characteristics. Color data Ci″, Mi″ for each of the cyan and magenta basic colors is converted in S112 into color data Cl and Cn and Ml and Mn for light ink and normal ink of the corresponding color based on the selected group of conversion tables T3.
