A decorator (10) for printing onto cylindrical structures (18) has a plurality of inkers (12). Each inker (12) has a pair of opposing frame plates (40, 48). A printing plate (204) is affixed to a printing plate cylinder (200) carried by a rotational printing plate cylinder shaft (202). The printing plate shaft (202) is disposed between the opposing frame plates (40, 48). A main shaft (38) supports the inker (12) on the decorator (10) such that the pair of opposing frame plates (40, 48) are slidable along a length of the main shaft (38). A lateral adjustment servomotor (220) acts on a corresponding inker (212) to impart a movement by the inker (12) along the length of the main shaft (38).

The invention relates to a method for the control of the rotational speed for a drive device (20) of a printing roll (10) with a resilient printing sleeve (12) of a flexo printing press (100) comprising the following steps: Determination of a first rotational speed (V1) of the printing roll (10) in the free wheeling without active drive device (20) with a first adjusting value (B1), Determination of a second rotational speed (V2) of the printing roll (10) in the free wheeling without active drive device (20) with a second adjusting value (B2), Generation of a control curve (30) of the rotational speed related to the adjusting value on the basis of the determination steps, Usage of the control curve (30) for the control of the rotational speed of the printing roll (10) with an active drive device (20).

Disclosed is a flexographic printing device for a laminating machine, including at least one pair of shoulders mounted on a trolley frame, a blade chamber for containing printing ink; an Anilox roller that rotates in contact with the printing ink, a print roller holding a printing clich? that rotates in contact with the Anilox roller and a counter-pressure roller that rotates in contact with the clich? held by the print roller, wherein at least the Anilox roller and the print roller are supported by respective supports that can slide with respect to the shoulders in a direction substantially orthogonal to their axes, the printing device also including at least one first motor for rotating the Anilox roller, at least one second motor for rotating the print roller and possibly a third motor for rotating the counter-pressure roller.

A system prints solid ink images on fibrous objects. The controller of the system is configured to operate a first motor to move an object rotating subsystem to and from a position opposite a plurality of printheads, to operate a second motor to rotate an object on a spindle of the object rotating subsystem at the position opposite the plurality of printheads, to operate a forced air heater to direct heated air onto a surface of the object as the object rotates at the position opposite the plurality of printheads, and to operate the plurality of printheads to eject a solid ink marking material onto the heated surface of the object as the object rotates in the first and/or second rotational direction. The solid ink image is affixed to the object by the heating of the object surface alone.

The present application discloses a screen printing device, comprising: a transport mechanism, which is used to carry and transport a plate to be printed disposed on the transport mechanism; a rotating frame located above the transport mechanism, which is used for winding a screen and driving the screen rotation; and a glue container located in the rotating frame and disposed to be independent of the rotating frame, wherein a lower portion of the glue container is provided with a glue outlet and a scraper, and the scraper is located beside the glue outlet. Since the screen printing device adopts a rolling printing mode, the tension generated by each position of the screen at the scraper is the same, thereby avoiding the poor printing uniformity due to the tension difference during the printing process.

A gravure coater test apparatus includes a gravure roll and a backup roll which are circumscribed to each other, a motor which drives the gravure roll partially submerged in a water-based pressure-sensitive adhesive for coating, a controller which adjusts the rotational speed of the motor, a doctor blade which is selected from a plurality of types to scrape the water-based pressure-sensitive adhesive from the surface of the gravure roll being rotated, and an infrared analyzer which allows at least one of the type of the water-based pressure-sensitive adhesive corresponding to the selected doctor blade, the uniformity of the coating surface, and the amount of the coated water-based pressure-sensitive adhesive to be confirmed.

Printer circuits and components for detecting a media low condition on a printer are provided. The printer circuit comprises a motor coupled to a platen roller, a current sense resistor coupled in series with the motor, a current measuring circuit comprising an operational amplifier circuit configured to receive input voltage and output voltage of the current sense resistor, generate a differential voltage based at least in part on the input voltage and the output voltage, and convert the differential voltage to a current, and an analog-to-digital converter and control mechanism configured to receive the current from the current measuring circuit and control operation of the motor based at least in part on the current.

An inking unit of a printing unit and a device for printing on hollow bodies each have a cylindrical lateral surface. The device comprises the inking unit. The inking unit has an anilox roller which receives a printing ink from an ink reservoir and has an inking roller placed against a printing cylinder of the printing unit. A rider roller is arranged axially parallel to the anilox roller in a region between the ink reservoir and the inking roller, that region being located subsequent to the ink reservoir in a direction of rotation of the anilox roller. The ink reservoir interacts with the anilox roller. The rider roller is placed against the anilox roller. The rider roller is rotationally driven by the anilox roller by friction. The inking roller is rotationally driven by the anilox roller by friction. The plate cylinder and the anilox roller are each independently rotationally driven by a motor.
