Abstract: A printed item contact member 54 according to the present invention includes: a base material 50; a fixing layer 52 that is formed on the surface of the base material 50 and substantially spherical particles 51 are fixed thereto; and a remarkably thin low-surface-tension coating layer 53 that covers the surface of the fixing layer 52 having the substantially spherical particles 51 fixed thereto and that exhibits release properties with respect to a printed item. The printed item contact member exhibits high ink repellency while maintaining the micro-uneven surface structure and is free from adhesion of yarn waste or dust to the member during cleaning, and therefore can be suitably used as, for example, a member for printing device in contact with the surface of printing paper.

Abstract: An image is created from PPF data and the image is displayed. An operator inputs a pre-set value of color adjustment from a color-adjustment-quantity operation screen. The color-adjustment-quantity operation screen includes a print display unit that displays a print color in a print measured by a calorimeter, a color-sample display unit that displays a target color in a color sample measured by the calorimeter, and a corrected-color display unit that displays a corrected color corresponding to a deviation between a calorimetric value of the print and a calorimetric value of the color sample.

Abstract: An image is created from PPF data and the image is displayed. An operator inputs a total amount of color adjustment as a pre-set value from a color-adjustment-quantity operation screen. An arithmetic unit adjusts a quantity of each ink component to be supplied to the areas based on the pre-set value. The arithmetic unit, for example, adds or subtracts certain values from the standard quantities. An ink supply device correspond to each ink component prints the image on a paper based on the quantity of each ink component adjusted by the arithmetic unit (12).

Abstract: An image is created from PPF data and the image is displayed. An operator selects one or more areas from the displayed image in which color adjustment is to be performed. An arithmetic unit adjusts a quantity of each ink component to be supplied to the areas selected by the operator based on standard quantities of ink for each ink component. The arithmetic unit, for example, adds or subtracts certain values from the standard quantities. An ink supply device correspond to each ink component prints the image on a paper based on the quantity of each ink component adjusted by the arithmetic unit.
