A printing apparatus comprises: a printing unit configured to print an image by applying, onto a printing medium, a first ink containing a fluorescent color material and a second ink containing not fluorescent color material but a resin; a decision unit configured to decide an amount of the second ink applied to a unit area on the printing medium based on an amount of the first ink applied to the unit area and luminescence information representing a luminescence intensity; and a control unit configured to control an application operation of the first ink and the second ink by the printing unit based on the amount of the first ink and the amount of the second ink applied to the unit area.

A system for droplet measurement includes an inkjet head including a nozzle which discharges droplets, a substrate on which droplets discharged from the nozzle of the inkjet head are dripped, a first detector disposed below the substrate and including a first camera and a first focusing structure, and a second detector disposed below the substrate and including a second camera and a second focusing structure.

A system is disclosed. The system includes at least one physical memory device to store drop size logic and one or more processors coupled with the at least one physical memory device to execute the drop size logic to receive first ink usage amount data for each of a plurality of color planes associated with a first halftone design and print job data, receive first ink drop size data for each of a plurality of color planes associated with the first halftone design, receive second ink drop count data for each of the plurality of color planes associated with a second halftone design and the print job data and determine second ink drop size data for each of the plurality of color planes based on the corresponding first ink usage amount data, the first ink drop size data and the second ink drop count data.

A liquid ejecting apparatus includes: a channel substrate having one or more pressure chambers, an absorbing chamber that absorbs vibration of a liquid; a vibration plate that is stacked on the channel substrate; a first piezoelectric element that is provided on a first surface of the vibration plate, which is on a side opposite to a side on which the pressure chamber is present, at a position overlapping the pressure chamber when viewed and that vibrates the vibration plate to apply pressure to the liquid; a second piezoelectric element that is provided on the first surface of the vibration plate at a position overlapping the absorbing chamber and that deforms to absorb the vibration of the liquid propagated from the pressure chamber; and a pressure detecting section that detects, based on an electromotive force of the second piezoelectric element, pressure of the liquid in the absorbing chamber.

In a control part of a printer, a main area information holding part holds information prescribing a plurality of main areas which are obtained by dividing at least a portion in a facing surface of a head into a plurality of areas in a predetermined direction. A sub-area information holding part holds information prescribing a plurality of sub-areas which are obtained by dividing the main area into a plurality of areas in the predetermined direction. The initial setting part designates the settings relating to corrections in units of the main areas. In a case where correction amounts of darkness based on the initial setting are different between a first main area and a second main area which adjoin each other among the plurality of main areas, the re-setting part maintains or redesignates the settings relating to corrections designated with respect to the first main area in units of the sub-areas.

An image forming apparatus for forming an image with a coloring material on a recording medium includes a region specifier that specifies a region that becomes a margin when the image is formed on the recording medium; and a pattern image generator that generates image data of a pattern image to be formed in the region based on a size of the region and a type of the coloring material.

A method includes illuminating a drop with a pulse of light from a light source. A duration of the pulse of light is from about 0.0001 seconds to about 0.1 seconds. The method also includes capturing an image, video, or both of the drop. The method also includes detecting the drop in the image, the video, or both. The method also includes characterizing the drop after the drop is detected. Characterizing the drop includes determining a size of the drop, a location of the drop, or both in the image, the video, or both.

A system and method for ejecting one or more fluids from a digital dispense device. The method includes selecting a) fixed target areas and total fluid volumes for the target areas of the substrate; b) a predetermined droplet volume for the target areas; c) calculating a required number of droplets for the target areas; d) determining a maximum number of droplets per pixel based on the target areas; e) calculating a number of droplets per pass of an ejection head over the target areas; f) modifying one or more dimension of the target areas to create modified target areas; g) selecting and centering the modified spot size target areas in the target areas; and h) depositing fluids in the modified target areas while scanning the ejection head over the modified target areas.

A post-processing device includes a first discharge unit, a processing tray, an end alignment portion, a transport unit that comes into contact with an upperface of a medium placed on the processing tray and transports the medium to the end alignment portion, a position changing unit that changes the relative position of the transport unit with respect to the processing tray, a controller, and a post-processing unit that performs a post-process on the medium on the processing tray, wherein the position changing unit is configured to move the transport unit to a transport position to which the medium is transported and a standby position farther away from the processing tray than the transport position, wherein the controller changes the standby position based on the processing information related to the process performed on the medium, and wherein the processing information includes information about a process performed on the first medium.

A printer includes a print head to print a pixel by ejecting drops of a printing fluid from the print head, and a controller. The controller monitors a drop volume of the printing fluid ejected by the print head. When the drop volume is below a threshold, the controller controls the print head in accordance with a first print mode to increase the frequency of ejecting drops of the printing fluid within the pixel print time with a decrease in the drop volume that maintains a print quality parameter. The controller changes to a second print mode to increase the pixel print time that maintains the print quality parameter.
