Abstract: An image processing apparatus comprising: a decision unit configured to decide a first color mapping method to a print color gamut for a first partial original based on a pixel value included in the first partial original and the print color gamut of a print unit and decide a second color mapping method to a print color gamut for a second partial original based on a pixel value included in the second partial original and the print color gamut of the print unit; and a color conversion unit configured to perform color conversion of the first partial original by the first color mapping method decided, and perform color conversion of the second partial original by the second color mapping method decided.

Abstract: An image processing apparatus obtains image data that is defined as a first color gamut, transforms the image data into image data that is defined as a second color gamut, using color transformation information, and when, as a result of transformation, a first pair of color values included in the image data is transformed into a second pair of color values that have a color difference that is not perceived as different colors, generates second color transformation information such that the first pair of color values is transformed into a third pair of color values that have a color difference that is perceived as different colors as a result of transformation using the second color transformation information. A saturation difference of the third pair of color values is larger than a saturation difference of the second pair of color values.

Abstract: Disclosed is a method for the compaction of a soft magnetic powder capable of manufacturing a green compact which has attained high density and high strength, is excellent in mechanical properties and magnetic properties, and does not cause a reduction in electrical resistance. Soft magnetic powder particles individually surface-coated with an insulating vitreous layer containing P, Mg, B, and Fe as essential components are used, and a lubricant is applied to the inner wall surface of a compaction die. The soft magnetic powder is subjected to compaction at from not less than room temperature to less than 50° C. without mixing the lubricant with the soft magnetic powder, followed by annealing at from 50 to 300° C.

Abstract: Disclosed is a powder metallurgical mixed powder capable of preventing the defective dispersion, that is, the segregation of physical property improving powders and a lubricant powder without reduction in lubricity, and of suppressing the generation of dust upon handling of powders; and a powder metallurgical binder capable of realizing such a mixed powder. The binder including a copolymer containing monomer components of ethylene and propylene, which may be combined with a liquid binder having a specified composition as needed, is added to a powder metallurgical raw powder.
