In an image-recording device, a cartridge has a first chamber and an outlet. A mount body includes a tank, first and second sensors. The tank has an inlet, and a second chamber. The liquid in the first chamber flows into the second chamber via the outlet and the inlet. The first sensor outputs a first signal when a level of the liquid in the second chamber is higher than a first position, and outputs a second signal when the level is lower than the first position. The second sensor outputs a third signal when the level is higher than a second position higher than the first position, and outputs the fourth signal when the level is lower than the second position. A controller controls a notification device to issue a notification if a condition based on the first and second signals is satisfied.

A technique includes printing a first image including a plurality of edge pixels and a second image with a lower ratio of edges pixels than the first image and an average density equal to that of the first image and determining a value of a processing parameter so that the average densities of the first image and the second image match. The technique is configured to realize appropriate pre-print processing while preventing the average densities from being low due to the excessive pre-print processing or being high due to the insufficient pre-print processing.

A printing method for performing printing while complementing black with composite black, the printing method including: printing a test pattern having a plurality of patch images for which composite mode varies, this test pattern being printed for each dot size of the black to be complemented; causing a user to select a desired patch image from among the plurality of the patch images included in the printed test pattern, the selection being made for each of the dot size of the black ink to be complemented; and performing printing while complementing the black to be complemented with the composite black generated on a basis of the composite mode corresponding to the desired patch image selected correspondingly to the dot size of the black ink to be complemented.

Method for manufacturing a microarray and verifying the quality of said microarray, wherein the method comprises: —providing at least one reagent, —loading said at least one reagent in a dispensing print head, in a predetermined arrangement, —moving the print head with respect to a substrate and dispensing said at least one reagent on the substrate, during a print pass, to obtain a microarray, —illuminating the substrate using illumination means and obtaining an image of the printed microarray on the substrate, using a camera, —processing the obtained image to verify the quality of the microarray, wherein the step of obtaining an image of the printed microarray comprises: —illuminating the substrate and obtaining an image of the microarray by means of illumination means and a camera which are connected to and move together with the print head with respect to the substrate, the illumination means and the camera being adapted to move behind the print head.

The disclosed embodiments include a method to compensate for defective printer nozzles. The method can include detecting a defective printer nozzle and initiating a print job including image data of the defective printer nozzle for a pixel location of an image. The image is to be printed in accordance with a print mask that maps printer nozzles to pixel locations of the image. The method can include modifying the image to print the image data in a neighboring pixel location relative to the pixel location of the image and printing the modified image.

Disclosed is an industrial single-pass inkjet printer/press incorporating a line-scan camera. The line-scan camera enables system software to inspect every sheet for quality assurance purposes. These inspection results are tied back to a digital printer to take one or more of several possible actions. Actions include ensuring a particular number of acceptable prints are generated and sorted. Actions further include performing nozzle checks without pausing or interrupting production orders.

The pretreatment liquid of the present invention is applicable for a fabric to be used for inkjet textile printing, and the pretreatment liquid contains a block copolymer including a hydrophobic block derived from a hydrophobic resin having an SP value of less than 11 and a hydrophilic block derived from a hydrophilic resin having an SP value of 11 or more, with the difference between the SP values of the hydrophobic resin and the hydrophilic resin of 1.0 or more; and water.

A printing device is provided with a print head having a plurality of nozzles configured to eject ink droplets therefrom, a supplier configured to supply ink contained in a container to the print head, and a controller. The controller is configured to perform obtaining ink information having correlation with a height of a liquid surface of the ink contained in the container, obtaining subject image data representing an image to be printed, generating print data based on the subject image data, and causing the print head to eject ink droplets based on the print data. The generating includes adjusting the print data in accordance with the ink information.

An example of a multi-fluid kit includes a pretreatment fluid, a fixer fluid, and a white inkjet ink. The pretreatment fluid includes anionically modified cellulose nanocrystals and a first aqueous vehicle. In some examples, the fixer fluid includes an azetidinium-containing polyamine and a second aqueous vehicle. The multi-fluid kit is suitable for use in inkjet textile printing.

An ink set contains a white ink composition containing a white coloring material and a resin, and a non-white ink composition containing a non-white coloring material and a resin. The white ink composition and the non-white ink composition are used with a treatment liquid containing a coagulant for coagulating a component of the non-white ink composition. When a 5% by mass calcium acetate monohydrate aqueous solution and each of the ink compositions are mixed, a ratio of the viscosity increase after the mixing to the viscosity increase before the mixing is lower in the white ink composition than in the non-white ink composition.
