Abstract: In image forming apparatus, a control unit determines nozzles corresponding to the image to be printed, correspondingly to a position of a print sheet, and causes a recording head to eject ink from the nozzles. A correction processing unit performs a correction process corresponding to each of plural ink ejection malfunction positions in the image. If the number of the ink ejection malfunction positions detected with a predetermined ink droplet size exceeds a predetermined upperlimit value, the correction processing unit prints a test pattern using the control unit with an ink droplet size larger than the predetermined ink droplet size, determines as a preferential ink ejection malfunction position an ink ejection malfunction position that ink ejection malfunction is also detected in the test pattern on the basis of a scanned image of the test pattern, and preferentially performs the correction process for the preferential ink ejection malfunction position.

Abstract: Bidirectional multi-pass printing with three or more passes prints a high-quality image with reduced time difference unevenness. To this end, an image in a unit region on a printing medium is printed by a print head performing 2N+1 bidirectional print scans (where N is a natural number). In this printing, a print permission rate for an even-numbered print scan of the 2N+1 times of the print scans is set lower than the print permission rate for an odd-numbered print scan of the 2N+1 times of the print scans.

Residues of the one or more fluids that were not transferred to the target substrate (50) and remained on the ITM (44), are transferred from the ITM (44) to one or more rotatable elements (112), and the residues are removed from the one or more rotatable elements (112).

Abstract: An inkjet printing method forming a decorative printed layer having a three-dimensional texture on a printing surface is described. The inkjet printing method includes: printing dots of curable ink that cure under a predetermined condition based on dot pattern data indicative of printed positions of the dots to be printed on the printing surface; and curing the printed dots. The dot pattern data indicates that: a distance between the adjacent dots becomes a distance where the adjacent dots before the curing are allowed to be maintained independently without bonding to one another in a first region; and the distance between the adjacent dots becomes a distance where the adjacent dots before the curing bond to one another in a second region different from the first region. Such a method may allow forming a decorative printed layer having a three-dimensional texture with a desired gloss level.
