摘要:
An inkjet printing apparatus includes a print head that scans a same area of a printing medium plural times and ejects plural kinds of ink and a treatment liquid thereon to form an image, and an ejection data generating unit for generating ejection data for ejecting the plural kinds of ink and the treatment liquid to each predetermined area of the printing medium in a predetermined order from the print head. The plural kinds of ink are classified in plurality based upon a minimum application amount of the treatment liquid per a predetermined area required for realizing an effect of the treatment liquid, and the ejection data generating unit generates the ejection data in such a manner as to eject the plural kinds of ink and the treatment liquid from the print head according to the order determined in accordance with the classification of the ink ejected within the predetermined area.

The present invention has an object of providing an inkjet printing apparatus which can improve image performance while restricting an ink consumption amount of a treatment liquid. The present invention generates ejection data for ejecting the plural kinds of the ink and the treatment liquid to each predetermined area of a printing medium in a predetermined order from the print head. The plural kinds of the ink is classified in plurality based upon a minimum application amount of the treatment liquid per a predetermined area required for realizing an effect of the treatment liquid. Ejection data generating unit generates the ejection data in such a manner as to eject the plural kinds of the ink and the treatment liquid from the print head according to the order determined in accordance with the classification of the ink ejected within the predetermined area.

摘要:
One or more scans used to apply a specific ink are varied according to the overlapping conditions of the specific ink and a non-specific ink, and bias in the specific ink nozzle usage frequency and bias in the printing ratio among passes is suppressed. For this purpose, one or more scans used to apply the specific ink are determined on the basis of applying amount information for the specific ink and the non-specific ink. For example, the one or more scans used to apply the specific ink are determined such that the ratio of specific ink applied by the last half of plural scans is greater for a unit pixel whose application ratio of non-specific ink to specific ink is greater than a predetermined ratio than for a unit pixel whose application ratio of non-specific ink to the specific ink is less than the predetermined ratio.
摘要:
The present invention provides an ink jet printing apparatus, an ink jet printing method, a data generation apparatus, a computer program, and an ink jet printing system by which a timing for ejecting a processing liquid can be changed to improve image performance of a printed image such as abrasion resistance, to provide the printing head with a longer life, and to improve a throughput. The processing liquid is ejected to a predetermined area on a printing medium, for which a formation of an image by ink is completed, in two or more scannings among five scannings of the printing head. When an amount of ejection data for ejecting the processing liquid in the fifth scanning for ejecting only the processing liquid is equal to or lower than a predetermined amount, the fifth scanning is not carried out.
