There are provided an ink jet printing apparatus, a dummy jet method, and a program which can execute a dummy jet at a dummy jet execution timing in which a use status of a nozzle is taken into consideration. A non-jettable period and a required jetting amount of an ink jet head are set for each nozzle, and in a case where the dummy jet for a dummy jet execution nozzle is executed with a jetting amount insufficient for the required jetting amount, at a determination timing of determining the necessity of execution of the dummy jet, for the nozzle of which a total jetting amount in the non-jettable period is less than the required jetting amount, the dummy jet is not executed in a case where a period from a printing start to a next jetting timing is equal to or greater than a period obtained by adding a determination interval to a period from the printing start to the determination timing.

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.

An apparatus for printing discrete high-resolution high-density features on a surface is provided using an aerosol stream. An aerosol chamber has a transport gas that enters through a port and entrains aerosol in an aerosol chamber to form an aerosol-laden transport gas. A flow cell is provided that has a flow cell channel and sheath gas conduits. The aerosol-laden transport gas passes through the flow cell channel and is surrounded by sheath gas passed through the sheath gas conduits. At least one aerodynamic lens receives the aerosol-laden transport gas surrounded by sheath gas. A method of printing the aerosol droplets from the aerosol-laden transport gas onto the substrate with a mean diameter of 0.5 to 8 microns is also provided.

An inkjet recording device and a method for controlling an inkjet recording device are provided. A heating device that heats the ink to be supplied to a nozzle immediately ahead of the nozzle, a thermometer that detects a temperature of the ink inside the heating device or after heating, a viscometer that detects a viscosity of the ink in a main ink container are provided. The heating device is driven using a detection value of the thermometer to control the temperature of the ink such that the viscosity reaches an ink viscosity which enables normal printing, and when the viscosity of the ink is out of a range which enables printing, the solvent or the replenishment ink is supplied to the main ink container using a detection value of the viscometer such that the viscosity reaches the range which enables normal printing.

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.

A liquid discharge method of discharging a liquid from a nozzle of a liquid discharge head by applying a drive pulse to a drive element of the liquid discharge head includes an acquisition step of acquiring a recording condition including a first discharge characteristic and a second discharge characteristic of the liquid from the liquid discharge head, a determination step of determining the drive pulse to be applied to the drive element, based on the recording condition, and a driving step of applying the drive pulse determined in the determination step to the drive element. In the liquid discharge method, in the determination step, the drive pulse is determined by a determination method subjected to weighting in which a weight of the first discharge characteristic is greater than a weight of the second discharge characteristic.

A liquid ejecting apparatus includes a carriage that mounts a liquid ejecting head provided with a nozzle surface in which nozzles to eject a liquid are formed, and is configured to move the liquid ejecting head between an ejection area used to cause the liquid ejecting head to eject the liquid onto a medium and a maintenance area used to perform maintenance of the liquid ejecting head, and a liquid receiving portion that has a size equal to or larger than the nozzle surface, is opposed to the nozzle surface located at a detachment position defined in the maintenance area, and receives the liquid discharged from the nozzles when detaching a liquid supply coupling portion detachably coupled to the liquid ejecting head.

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 printing apparatus includes a print head to print a print material on a support; a feed device feeding the print material to the print head; and a recirculating unit generating a recirculation of the print material through the print head and having a first container of the print material placed upstream of the print head, a second container of the print material placed downstream of the print head, a first recirculating sub-unit generating a first flow of the print material from the first container to the print head and the second container, and a second recirculating sub-unit transferring the print material from the second container to the first container, wherein the first and second containers are both maintained under two distinct negative pressures.

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.
