Abstract: Images, one per page, are printed by a digital printer consecutively on a web of paper fed to travel forward. A timing mark is printed for each image. In case printing is temporarily halted, the web of paper is first fed backward, and then it is fed forward again. The number of timing marks in each of the backward feed and forward feed of the web of paper are counted. When the number of counts of the timing marks counted in the forward feed coincides with the number of counts of the timing marks counted earlier in the backward feed, printing of consecutive images is reinitiated from a position immediately following an image last printed before printing was temporarily halted.

Abstract: The present invention is directed to an inkjet recording apparatus 100 capable of performing recording continuously on both surfaces of a web, including a plurality of recording heads disposed on a substrate, driers for drying the web recorded by the recording heads, and guide rollers for guiding the web, in which a traveling path of the web is switchable so that the web passes between any selected adjacent ones of the recording heads, the recording head upstream of the position where the web passes performs recording on one surface of the web, and the recording head downstream of the position where the web passes performs recording on the other surface of the web, and an inkjet recording method using the same.

Abstract: An ink jet recording apparatus in which a head supporting plate having a line head mounted thereon which comprises a plurality of short heads staggered is attached to a carriage whereby recording is performed by ink jet printing with the line head on a recording medium positioned beneath the carriage is rendered capable of using ordinary short heads.

Abstract: To enable fabric of any length to be continuously printed without causing a textile printing unit to cease its operation, a textile printing method is provided in which fabric is conveyed by a conveyer belt and passed through a printing section to print on the fabric, the printing section having a textile printing ink jet printer disposed opposite the conveyer belt, wherein the printing section is continuously supplied with the fabric comprising a plurality of successive sheets of fabric, each sheet having a given length, such a sheet of fabric for supply into the printing section having a terminal end tied with a starting end of a sheet of a fabric for continuous succeeding supply in the state that the terminal and starting ends are in contact with each other.

Abstract: A drum-type drying device according to the invention includes a cylindrical drum section that is rotatably supported and rotated by winding a base material on the drum section, engaging portions that are disposed in an inner cavity of the drum section, and a heating section that includes engaged portions detachably engaged with the engaging portions.

Abstract: Fluttering of paper traveling opposite to and parallel to a nozzle width region of an ink jet head is held down, thereby improving the printing quality. An ink jet recording apparatus comprises an ink jet printer including printing units (7, 7?) whereby a sheet of paper (2) traveling in a paper passage in the form of an arch shaped by a plurality of guide rollers (12a-12h) is printed by a plurality of ink jet heads (6a-6d, 6a?-6d?). The ink jet heads of the printing units comprise ink jet heads of on-demand type having a plurality of nozzle rows of a nozzle width region in a direction of travel of paper. The paper passage opposite to nozzle faces of each ink jet head nozzle defined by two guide rollers (12a, 12b) positioned at an upstream and at a down-stream side in the direction of travel of paper, respectively.
