An irradiation device includes: an irradiation, unit that irradiates a target with light; at least one component that is arranged in an advancing direction of light reflected by the target; and a light blocking unit that is arranged between the target and the at least one component in the advancing direction and blocks the reflected light.

A machine for the digital decoration of products with granular materials and the like, comprises: a basic frame; at least one supporting surface for supporting at least one product to be decorated associated with the basic frame; at least a first digital printing head adapted to apply at least a first layer of fluid adhesive material on the surface of the product to be decorated; a deposition component/device/unit/circuit or the like of a granular material on the first layer of adhesive material; a removal component/device/unit/circuit or the like of the excess granular material; at least a second digital printing head adapted to apply at least a second layer of fluid adhesive material on top of the granular material, the second printing head being positioned between the deposition component/device/unit/circuit or the like and the removal component/device/unit/circuit or the like.

A printing machine for printing fabrics on a rotary drum, comprises one or more drums rotatable about a drum axis, that receive tubes of fabric thereon, and a print head placed in proximity to the drum, to print onto the fabric fitted onto the drum. The print head comprises multiple printing nozzles or linear arrays of printing nozzles which are aligned linearly along the axial direction of the drum, which are all at a predefined printing distance from the drum surface or the fabric surface. Also, a rotary drum for a textile printer comprises a groove extending along the length of the drum, and a catch mechanism built into the groove for catching on to a garment or backing for a garment as the drum rotates. The rotation of the drum pulls the caught edge and wraps the garment around the drum ready for rotary drum printing.

The invention relates to an apparatus (1) for irradiating a substrate (2), which apparatus comprises a platform (4), which is straight or curved in relation to the longitudinal axis (3) of the platform (4), wherein one, two, three, four, five, six, seven, eight, nine, ten or more irradiation modules (6) and/or substrate supply air modules (36) and/or substrate exhaust air modules (37) are reversibly attachable directly or indirectly to the bottom side (8) of the platform (4) by sliding or inserting or mounting in one or more fixed or telescoping module attachment devices (10) provided on the bottom side (8) of the platform (4) - each extending from the front side (5) of the apparatus (1) and in the direction of the back side (9) of the apparatus (1).

A liquid discharge apparatus is provided that includes a transport unit configured to transport a medium, a discharge unit configured to discharge a liquid onto the medium, a housing including therein the discharge unit, a humidifying unit configured to humidify an interior of the housing, and a humidity detection unit configured to detect a humidity. When the humidity detection unit detected a humidity less than a lower limit value (one example of a first predetermined value) (positive determination in step S12), the interior of the housing is humidified by the humidifying unit during transport by the transport unit or during discharge by the discharge unit (step S16).

A printing apparatus includes: an ejection head that prints an image on a recording medium supported by a support member by ejecting liquid from a nozzle formed in a portion facing the support member; and an irradiation section that includes a housing which is open toward the support member, and a light emitting section housed in the housing and emitting light to cure the liquid, the irradiation section being configured such that light emitted from the light emitting section is irradiated onto the recording medium supported by the support member via the opening, wherein the housing includes an inclined section which extends from the opening toward the ejection head such that a distance from the inclined section to the support member decreases toward the ejection head, and the inclined section is provided so that θ2>θ1 is established.

Provided is a liquid ejecting device. An alternating current electric field generation unit includes a first electrode and a second electrode disposed adjacent to each other, a high-frequency voltage generation unit configured to generate a high-frequency voltage to the first electrode and the second electrode, and a conductor configured to electrically couple the first electrode and the second electrode to the high-frequency voltage generation unit. The first electrode and the second electrode face the support portion and are disposed downstream of the liquid ejecting head in a transport direction of the medium. A surface of the support portion facing the liquid ejecting head, the first electrode, and the second electrode is constituted by an insulating body.

The present invention provides a glass slide printer, which comprises: a conveying device, an inkjet device, and a curing device; wherein the conveying device has a conveying path, and causes the glass slide to be printed to move along the conveying path; the inkjet device is provided above the conveying path, and is configured to perform inkjet printing on the marked area of the glass slide on the conveying path; the curing device is provided above the conveying path, and the curing device is located downstream of the inkjet device; the curing device is capable of curing the printing ink droplets ejected onto the glass slide to form characters or two-dimensional codes by heating or ejecting curing liquid.
