    摘要： A method for monitoring a characteristic of a printed image of a thermal transfer printer. The method comprises providing a ribbon and a substrate at a printing location of the thermal transfer printer. The method further comprises printing an image on the substrate at the printing location by transferring ink from a region of the ribbon in a printing operation, a negative image being formed on the region of ribbon. The method further comprises transporting the region of ribbon, by a ribbon transport system, from the printing location towards an imaging location along a ribbon transport path. The method further comprises when a characteristic of the ribbon transport meets a predetermined criterion, obtaining, by an image capture system, a ribbon image of the negative image. The method further comprises processing said ribbon image to generate data indicative of the characteristic of the printed image.

    摘要： A print processing portion causes a print device to execute printing of a print image based on print data in accordance with a first scanning amount detected when manual scanning is performed at a first time. A density complementation processing portion causes the print processing portion to execute reprinting in accordance with a second scanning amount detected when the manual scanning is performed at at least a second time. When the manual scanning is performed at at least the second time, the density complementation processing portion identifies density insufficient parts in the print image printed by the print device based on the scanning amount and an image read by an optical reading device. Furthermore, the density complementation processing portion causes the print processing portion to execute the reprinting for the density insufficient parts.

    摘要： Irregularities in the density that can occur in printed images of a thermal transfer printer due to mechanical variations or variations in thermal characteristics in the thermal head are more easily and accurately corrected as compared to cases not having the features of the disclosed invention. The thermal transfer printer includes a thermal head including heating elements and causing the heating elements to generate heat and transfer ink onto a sheet to print an image on the sheet, a storage unit for storing a first correspondence between a heating element in the thermal head and a correction amount of energy applied to the heating element and a second correspondence between a density of an image to be printed and an adjustment coefficient of the correction amount, and a control unit for correcting energy applied to each heating element by an amount obtained by multiplying the correction amount for the heating element obtained from the first correspondence by the adjustment coefficient obtained from the second correspondence according to a density of an image to be newly printed. The first correspondence is generated from a density distribution of a test image printed based on image data of a single tone.

    摘要： A liquid ejecting method includes ejecting droplets of an oil-based ink containing an oil-based medium onto a recording medium by using an ink jet head having a plurality of nozzles under the conditions satisfying relationships (1): f×D≧4800; and relationship (2): 5≦ρVd/η≦30. In the relationships (1) and (2), D represents the nozzle pitch in dpi of the ink jet head, f represents the maximum ejection frequency in kHz, V represents the velocity in m/s of droplets ejected from the ink jet head, d represents the diameter in μm of the droplets of the oil-based ink, ρ represents the density in g/cm3 of the oil-based ink, and η represents the viscosity in mPa·s of the oil-based ink.

    摘要： Damage caused to a transfer medium due to heat when partially using transfer material regions is suppressed. An image forming apparatus (1) includes a transporting unit (4A, 4B) which transports a belt-like transfer medium (4) on which transfer material regions (Y, M, C, OP) of a first size respectively corresponding to transfer materials are arranged in a predetermined order in a repeated manner along a longitudinal direction thereof, and an image forming unit (3) which transfers the transfer materials in sequence by heating the respective transfer material regions and thereby forms on a recording medium an image with the first size or an image with a second size which is not larger than one half the first size. When forming an image with the second size, the image forming unit either uses unused portions of transfer material regions that have already been used to form an image with the second size or uses new transfer material regions on the transfer medium. When forming the image with the second size by using the new transfer material regions, the image forming unit performs the image formation at a slower speed than when forming an image with the first size.
