A drying device includes a heater, a supporter, a controller, and a temperature detector. The heater heats a medium. The supporter is disposed opposite the heater to support the medium. The controller turns on the heater while the medium is conveyed, and turns off the heater when the medium is stopped. The temperature detector detects a temperature of the supporter. The controller is connected to the temperature detector to turn off the heater when the temperature detected with the temperature detector is a predetermined temperature or higher.

In a printing device, a controller is configured to perform: (a) writing; (b) printing; (c) determining; (d) conveying; (e) writing; (f) printing; and (g) writing. The (a) writing writes prescribed information to an information storage medium provided in a first print medium. The (b) printing prints a prescribed image on the first print medium. In response to determining in (c) that the printing quality of the prescribed image is not good for the first print medium, the (d) conveying conveys a continuous medium in a reverse direction, the (e) writing writes void information to the information storage medium provided in the first print medium, the (f) printing prints a VOID image on the first print medium after the (e) writing is performed, and the (g) writing writes the prescribed information to the information storage medium provided in a second print medium prior to performing the (f) printing.

Heating device, dryer, liquid discharge apparatus, and printer

A heating device includes a conveyor configured to convey a sheet, the sheet having a first surface on which a liquid is applied and a second surface contacting the conveyor, a first heater facing the first surface opposite to the second surface of the sheet, the first heater configured to heat the sheet, and a second heater configured to heat the conveyor.

METHOD FOR DRYING A MATERIAL FOR IRRADIATION, AND INFRARED IRRADIATION DEVICE FOR CARRYING OUT SAID METHOD

Known infrared irradiation devices for drying a material for irradiation that is moved through a process chamber have a radiator unit with at least one infrared radiator for emitting infrared radiation and have a counter-reflector with a reflector wall, wherein the reflector wall has a plurality of inlet openings for admitting cooling gas into the reflector space. Proceeding from this, in order to provide an irradiation device for the drying method, which irradiation device is, in particular for drying solvent-containing and in particular water-based printing ink, distinguished by high-speed drying with a low level of bubble formation and a low level of condensation in the reflector space at the same time, it is proposed that the reflector wall has at least one outlet opening for conducting waste air out of the reflector space.

Printing apparatus for performing printing to an elongated print medium

Disclosed is a printing apparatus in which web paper is transported to a printing face contact roller in a swirling form while a direction thereof is turned by first to fourth turning rollers. Heating units are arranged so as to face a printing face of the web paper between the two first and second turning rollers, between the two third and fourth turning rollers, and between the fourth turning roller and the printing face contact roller individually. Such arrangement can achieve a compact drying mechanism. The heating units each directly heat inks on the printing face, and thus do not overheat the web paper. Moreover, the heating units are not directed upward. This avoids contact of the web paper to a front side face of each of the heating units when the web paper slackens.

ink includes water, an alcohol having a boiling point of 240 degrees C. or lower, and an infrared absorbent, wherein the alcohol accounts for 5.0 percent by mass or more of the total amount of the ink and the ink is free of an alcohol having a boiling point higher than 240 degrees C.

Drying ink in digital printing using infrared radiation

A system (10, 110) includes: (i) a flexible intermediate transfer member (ITM) (44, 500, 600), including: a stack of: In (a) a first layer (602), located at an outer surface of the ITM (44, 500, 600), configured to receive ink droplets to form an ink image thereon, and to transfer the ink image to a target substrate (50, 51), and (b) a second layer (603) including a matrix holding particles (622), configured to receive optical radiation (99) passing through the first layer (602), and to heat the ITM (44, 500, 600) by absorbing the optical radiation (99); (ii) an illumination assembly (113), configured to dry the ink droplets by directing the optical radiation (99) to impinge on the particles (622); and (iii) a temperature control assembly (121), configured to control a temperature of the ITM (44, 500, 600) by directing a gas (101) to the ITM (44, 500, 600).

SYSTEM AND METHOD FOR PRINTING DOCUMENTS WITH TEXTURE

An aqueous inkjet printer also ejects drops of UV material on an aqueous ink image and exposes the aqueous ink image and the UV material to UV radiation before passing the aqueous ink image and UV material through a thermal dryer. The exposure to UV radiation pins the UV material to the aqueous ink image and underlying substrate and the thermal dryer fixes the aqueous ink image to the substrate while releasing free radicals from the UV material. Thus, the printer produces textured prints that do not have free radicals that can irritate skin or produce noxious odors.

IMAGE FORMATION DEVICE WITH RADIATION FIXATION

An image formation device includes at least one frame portion supporting at least one emitter to emit airborne charges, at least one radiation element to emit radiation, and a fluid ejection device to deposit droplets of ink particles within a non-aqueous fluid carrier onto a substrate. Upon relative movement between the at least one frame portion and the substrate, the emitted airborne charges are to electrostatically fix, and the at least one radiation element is to emit radiation to cause at least further fixation of, the deposited particles relative to the substrate.
