Abstract: A heating lamp unit (40) is mounted on a head carriage (10) of an inkjet printer (1). Since the heating lamp unit (40) is positioned very close to an ink drop, which is discharged from the inkjet head (11) and dropped on a recording medium (30), and that the heating lamp unit can directly harden the ink drop with heat, the ink drop can be efficiently fixed. When the heating lamp unit (40) is arranged very close to the inkjet head (11), there are possibilities of generating clogging of the nozzle of the inkjet head (11) and thermal failure of the inkjet head itself due to heat released from the heating lamp (40). Since the heating lamp unit (40) can be efficiently cooled by a cooling mechanism (50) using heat pipes (51, 52), the inkjet head can be prevented from being heated.

Abstract: A printing device (1) is provided with an ink circulation passage (4) for circulating, via an inkjet head (2), pigmented ink stored in an ink tank (3). A bypass passage (5) which bypasses the inkjet head (2) is connected to the ink circulation passage (4). When printing is performed, ink is circulated via an ink damper (10) of the inkjet head (2), and when the device is on print standby, the pigment particles in the pigmented ink are prevented from settling in the ink passage by circulation of the ink via the bypass passage (5). When the device is on print standby, cleaning liquid supply passages (13, 14) are opened and a cleaning pump (19b) is driven so that the cleaning liquid is sucked out from a cleaning liquid tank (12) and made to pass through nozzles in the inkjet head (2), whereby the pigmented ink inside the inkjet head (2) is cleaned.

Abstract: A head carriage of an ink-jet printer is equipped with a heat lamp unit. The heat lamp unit is located very close to ink droplets discharged from an ink-jet head and landing on a recording medium and can directly heat and cure the ink droplets, so that the ink droplets can be efficiently fixed. If the heat lamp unit is placed very close to the ink-jet head, clogging of a nozzle of the ink-jet head and thermal failure of the ink-jet head itself may be caused by heat release of the heat lamp unit, but the heat lamp unit can be cooled efficiently by a cooling mechanism which circulates a refrigerant through a refrigerant circulating pipe by a refrigerant circulating pump, so that the ink-jet head can be prevented from being heated.

Abstract: A printing system for T-shirts applies a surface-treatment agent to a printing area of the surface of T-shirts set on a printing bed, by using a surface-treatment ink jet printer equipped with a spray nozzle of a valve-jet type. Next, white ink is applied to the printing area by an ink jet printer for the white ink, and a color image is then printed on the printing area by a color ink jet printer. The cloth-product printing operation needing the surface treatment can be efficiently performed by applying a surface treatment agent onto only the portion needing it with use of the spray nozzle of the valve-jet type.

Abstract: A T shirt stretching tool (4) in a closed state is inserted into a T shirt (5) of print object. The T shirt stretching tool (4) is opened to the right and left, the body portion (51) of the T shirt (5) is spread to the right and left and then the front part (51a) and the back part (51b) of the body portion are stretched to bring about a planar state (step for stretching clothing). The T shirt (5) spread to the right and left by the T shirt stretching tool (4) is then mounted on the medium mount (22) of an ink jet printer (2) while the front part (51a) is directed upward (step for setting clothing). Thereafter, the ink jet printer (2) is driven to print a print image at a set position of the front part (51a) in the body portion (51) of the T shirt (5). Consequently, a pattern can be printed neatly on a T shirt using an ink jet printer.

Abstract: In a rotary printing device, six printing racks disposed at equal angular intervals on the same circle revolve via the printing positions of six printing units arranged at equal angular intervals on the same circle. Five of the printing units are screen printing machines for printing designs and other matter common to the T-shirts. The remaining printing unit is an inkjet printer whereby the wearers' names and other types of individual information specific to each T-shirt are printed on the T-shirts. A highly versatile printing device capable of printing names and other individual information on T-shirts can be attained.

Abstract: In an artificial nail printing system (201), each artificial nail printing shop (204) has numerous containers (212) containing artificial nail support bases (243) to which artificial nail materials (211) are adhered. When a customer chooses a desired container (212) and artificial nail printing data, the artificial nail support base (243) is removed from the container and positioned as is, on a carrier surface (74) of the media transport tray (7) of an inkjet printer (1). By transporting the media transport tray (7), each artificial nail material (211) adhered to the artificial nail support base (243) carried thereon is printed. After the printing, the printed surface of the artificial nail material (211) is dried and a protective topcoat is applied.

Abstract: An image is printed on a canvas (4) using an inkjet printer (9) (step ST2). Desired portions in a printed image (11) are coated with white primer material to form a concavo-convex surface (12) corresponding to the printed image (step ST3). White paint (13) is applied on top of the concavo-convex surface (12) (step ST4), and an ink-receiving surface (14) capable of absorbing water-base ink is then formed (step ST5). The same image is reprinted at the same location using the inkjet printer (9) (step ST6). Finally, a printed image (15) is covered with a durable and water resistant protective film (16) (step ST7). Concavities and convexities are formed on the printed image (11), the same image is reprinted at the same location thereon, and a three-dimensional printed picture exhibiting the same state of concavities and convexities as an original oil painting is therefore obtained.

Abstract: In a method of advertising using a delivery truck the present invention, a water-base ink image reception layer is formed on a surface of signboard materials (1 (1) to 1 (3)) constituted of cardboard or the like, desired advertising information is printed thereon using an inkjet printer and the printed surface is protected by a surface protection layer to thereby manufacture advertising signboards (10 (1) to 10 (3)). Next, the advertising signboards are removably attached to a side surface (14) of a van body (13) of a delivery truck (12).
