Image recording apparatus and image recording method for printing each of a plurality of unit images
Patent number: 10328728Abstract: This image recording apparatus includes recording heads and a detector for detecting a thick part of a recording medium. Before the thick part reaches a recording region, printing by means of the recording heads is stopped, and the relative position of the recording heads and the recording region is switched to a retracted position in the image recording apparatus. After the thick part passes through the recording region, the relative position of the recording heads and the recording region is switched to a printing position, and the printing of a new unit image is started from a position an integral multiple of a printing period apart from a last start position. This restrains a difference between the periods of image recording positions before and after the suspension of a printing step while restraining contact between the recording heads and the thick part.Type: GrantFiled: December 18, 2015Date of Patent: June 25, 2019Assignee: SCREEN HOLDINGS CO., LTD.Inventors: Keita Takagi, Toshio Maeda -

Patent number: 8888239Abstract: In an inkjet printer, a first sparsely arranged portion of a first ejection head entirely overlaps in a movement direction with a second densely arranged portion of a second ejection head. A plurality of outlets of the first sparsely arranged portion include use outlets, and among a plurality of outlets of the second densely arranged portion, those that overlap in the movement direction with use outlets of the first sparsely arranged portion are non-use outlets. In an overlapping range of the first ejection head and the second ejection head, outlets of both of the ejection heads are used in recording an image onto a base material. Consequently, it is possible to prevent or suppress a reduction in print quality such as changes in density or the occurrence of voids due to displacement of the mounting positions of ejection heads in the overlapping range.Type: GrantFiled: February 18, 2014Date of Patent: November 18, 2014Assignee: Dainippon Screen Mfg.
