Rotary printing press

The dual sided printing for card and other stiff sheet material has laser jet printing on each side in turn, with ultraviolet fixing of the print. The sheets can then be printed on one side using one or more rotary print processes. The print process does not smear the print on either side. The sheets are fed from a sheet feeder (17) onto a first transport roller (12) via a transfer roller (15). This provides a first ink jet print (13) on the front (22) of the sheets. A second transport roller (8) takes the sheets face down and passes them past ink jets for printing on the back. The final stage is a rotary print process (3,4,5) for printing onto the front of the sheets.

Method and apparatus for printing fluid on a substrate

Printing system

A method and apparatus are disclosed for treating ink droplets having a liquid carrier immediately after their deposition onto a liquid repelling surface of an image transfer member of an indirect printing system; the method comprises blowing a low velocity stream of gas onto the surface in a direction substantially normal to the surface to minimise disturbance of the ink droplets; the temperature and flow rate of the stream are sufficient to cause evaporation of the liquid carrier, and the duration of the exposure of the ink droplet to the stream of gas is sufficient to form a skin on the surface of the droplet while the centre of the droplets remains as a liquid; the skin acts to fix the ink droplets to the surface and prevent bleeding between successively deposited ink droplets. The gas stream is applied by way of a head unit that incorporates a blower (204, fig 2) and a plenum chamber 202 containing diffusers 302 and a heater 304.

ACTIVE PAPER DROP FOR PRINTERS

ACTIVE PAPER DROP FOR PRINTERS An active paper drop mechanism for ink-jet printers is provided. The mechanism comprises a pair of opposed, movable rail members associated with opposed walls of a horizontally-disposed output collection tray for receiving sheets of printed media. Each rail member is provided with return spring that act to maintain the rails in a closed position.

HIGH-TURNAROUND, CLOSED-LOOP, DIRECT TO GARMENT PRINTING

In one embodiment, a high-speed, closed-loop fabric printer comprises a plurality of consecutive stations that can be managed by a single operator. In particular, shirts or other fabric garments may be individually loaded and secured on a pallet by an operator, and the loaded pallets may then cycle through a plurality of unmanned stations positioned along a contiguous path (e.g., oval). The stations may be configured for pretreating the fabric surface, drying and pressing the pretreated fabric with heat, and then inkjet printing a selected image, among others. In this manner, a "wet-to-dry-to-wet" direct to garment (DTG) printing process may thus be achieved, along with optimal controls for maximum adaptability. Furthermore, due to the closed-loop design, a recently printed fabric product returns to the operator to be unloaded at the position in which a new unprinted fabric is loaded, allowing for increased throughput and minimal operator requirements.

Most layers are cured/dried with U/V and/or I/R and/or Hot-air. Successive impact-protective layers can be DIJ printed. Other DIJ- printed wares include flat ware, metal-ware, pens, markers and pencils, DVD and CD discs, which wares may not require adhesion promoting material or printable under- coating. The work stations may overlie one or more carousels which transport the wares.

SYSTEM AND METHOD FOR IMAGE RECEIVING SURFACE TREATMENT IN AN INDIRECT INKJET PRINTER

An inkjet printer applies a layer of a hydrophilic composition, which includes a liquid carrier and an absorption agent, to an image receiving surface of an indirect image receiving member. A dryer in the printer removes a portion of the liquid carrier from the layer of hydrophilic composition to form a dried layer of an absorption agent on the image receiving surface and an aqueous ink image is formed on the dried layer. The aqueous ink image and at least a portion of the dried layer are transferred to a surface of a print medium as the aqueous ink image and print medium move through a transfix nip formed between the indirect image receiving member and a transfix member.

Ink Jet Printer

INK JET PRINTER

The present invention is an ink jet printer utilized to enlarge color images. Signals from a scanned image (50) are convened by a color correction computer (51) into control signals (54) representing the density of the individual pixels of that scanned image. The color density signals are used to control the application of ink from ink jet spray nozzles (23A-U) 25A-D) located on a pair of printheads (23, 25). Thus, the ink jet printer of the present invention reproduces the image on both sides of a translucent substrate (13) to enhance the quality of the viewed image. The present invention is further provided with dual air sources to apply the ink. A first air source (34) is pulse width modulated to control the amount of ink sprayed onto the substrate. A second air pressure source (33) is continuously applied to the ink jet spray nozzles to remove the excess ink that accumulates about the nozzles during print operations. The present invention, additionally, is provided with heaters (28) ...

INK JET IMAGE DRIER

The drier consists of a plurality of nozzles that direct a small volume of air onto the printed image at as high a velocity as possible without disturbing the wet image. The air so delivered while it must be dry, does not have to be heated to effectively dry the image, however, the drying time can be reduced by increasing the air temperature if desired. The use of high velocity air creates what is known is ~skin effect" to dry the ink where the outer surface of the ink is quickly dried.
