After specifying a processing target (target data), a requirement for printing is set. A simulation of a RIP process is performed on the target data under a plurality of printing conditions which are set in advance. Then, based on simulation results, a print-target identifying record is registered in a continuous printing list so as to satisfy the set requirement. After rearranging print-target identifying records registered in the continuous printing list, continuous printing is performed based on the continuous printing list.

A common profile is prepared that, in a device-independent first color system, converts image data of a color space that is representable by the first color system into image data of a color space that is commonly representable by the plurality of printing devices, and first image data representing an image to be printed is converted into second image data by using the common profile, where the image is represented by the first color system. Then, the second image data is converted into third image data by using an output profile, where the third image data is image data of a second color system that depends on a specific printing device designated from among a plurality of printing devices and the output profile is unique to the designated specific printing device. The third image data thus obtained is output to the designated specific printing device and printed.

The invention discloses various methods of controlling or monitoring the performance of a continuous inkjet printer based on monitoring vacuum levels and/or noise in the gutter line.

A print head of a binary continuous jet printer comprising: a plurality of nozzles for producing a plurality of ink jets in a cavity delimited by lateral walls, an upper wall and a lower wall, a sorting unit for separating drops or sections of one or more of the jets intended for printing from drops or sections that do not serve for printing, a slot, which passes through the lower wall, enabling the exit of ink drops intended for printing, a gutter for recovering drops or sections not intended for printing, a conduit for injecting gas into the cavity, and for making this gas circulate, in the cavity, to the plurality of nozzles for producing a plurality of ink jets in the cavity, then to the gutter.

An inkjet recording device includes a main body unit, a print head unit, and a head mounting unit. The main body unit includes an ink container. The print head unit includes a nozzle connected to the ink container. The head mounting unit is configured to allow the print head unit to be mounted on the head mounting unit. The head mounting unit includes a head detection unit that detects whether or not the print head unit is mounted, using a magnetic force.

A method of preparing a washable durable image on a polyester film from water-based inks using an ink-jet printer, wherein the method comprises providing a substrate having a coating comprising approximately 4% by weight of polyvinyl alcohol as a binder, approximately 30% by weight of Polyethylene powder as an ink absorbing pigment. An image is printed on the coated substrate and is then thermally fused to the coated substrate.

Techniques for operating an industrial printer include causing it to report data that indicates COO parameter values based on output sensors and/or component detection module configured to measure physical phenomena related to components of the printer referred to as COO parameters. The COO parameters values, which may include waste values, are derived and displayed in a graphical user interface dynamically on a real time basis. One or more graphical user interface is generated to present a one or more active areas to select the display of the COO parameter values in numeric and or graphical form or combinations thereof.
