A printer includes a platen, a first head, a second head, a first lamp, and a second lamp. The first head, the second head, the first lamp, and the second lamp are moved relatively with respect to the platen in a main scanning direction, and the platen is moved from the second head toward the first head relatively with respect to the first head, the second head, the first lamp, and the second lamp, repeatedly. The second head ejects the second ink onto the object to be printed placed on the platen while the first head, the second head, the first lamp, and the second lamp are moving in the main scanning direction. The first lamp irradiates light onto the second ink on the object to be printed while the first head, the second head, the first lamp, and the second lamp are moving in the main scanning direction.

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.

A liquid discharge apparatus includes a liquid discharge device and circuitry. The liquid discharge device includes a plurality of rows of nozzles. The circuitry determines a timing at which the plurality of nozzles discharge the liquid based on a density of a plurality of patch images. Each of the plurality of patch images includes a reference dot and an adjustment dot. The reference dot and the adjustment dot are formed by the liquid discharged from the plurality of nozzles in a first row and in a second row, respectively, of the plurality of rows of nozzles. The reference dot corresponds to a prescribed base pixel. The adjustment dot corresponds to an adjustment pixel adjacent to the base pixel in the width direction. The adjustment pixel is shifted from the base pixel in the conveyance direction by a number of pixels that differs for each of the plurality of patch images.

A computer-implemented method is provided for dosing ink in a digital printing device with multiple ink channels, when printing on a reflective substrate. A digital printing system configured with the method is also provided. Target color data of a target color to be printed on the reflective substrate is captured, including both color data and spectral reflectance data. The captured color data is processed with a printer model to output a preliminary dosing ratio for each ink channel. A digital opacity value for the target color is computed from the dosing ratio of each ink channel. A natural opacity value for the for the target color is computed from the captured spectral reflectance data, and a difference between the digital and natural opacity values is calculated. A predicted dosing ratio for each ink channel is obtained by interpolating the difference against an ink step of a diffuse ink component of the target color.

A printing device including: a print head which performs printing on a printing area in a first nail of a finger or a toe and next performs printing on a printing area in a second nail of a finger or a toe; a mover which moves the print head; and a processor. The processor sets a printing start position in the second nail in response to a printing end position of the printing area in the first nail, the printing start position in the second nail being at a side closer to either a nail tip-side end or a root-side end of the printing area in the second nail, and controls the print head and the mover to perform the printing on the printing area in the second nail from the printing start position in the second nail after the printing is finished for the first nail.

A printer includes a head, a flushing receiving member, a cap, a processor, and a memory. The head is provided with a nozzle surface intersecting a discharge direction and configured to move in a main scanning direction. The flushing receiving member is positioned in the discharge direction with respect to a movement path of the head in the main scanning direction. The cap is configured to closely adhere to the nozzle surface. The cap and the flushing receiving member are arranged in the main scanning direction. The memory stores computer-readable instructions that, when executed by the processor, instruct the processor to perform a process including flushing processing including a first flushing operation of discharging ink from the head toward the cap, and a second flushing operation of discharging the ink toward the flushing receiving member while moving the head in the main scanning direction.

A printer is provided with a first nozzle surface including a first nozzle row, a second nozzle surface including a second nozzle row positioned with respect to the first nozzle row in a main scanning direction, a receiver having a width smaller than an interval between the first nozzle row and the second nozzle row, and a driver. A processor of the printer causes the driver to perform a discharge driving to discharge ink from at least one of nozzles of one of the first nozzle row or the second nozzle row, and causes the driver to perform a non-discharge driving to not discharge ink from at least one of nozzles of the other of the first nozzle row or the second nozzle row, in a state of one of the first nozzle row or the second nozzle row being caused to face the receiver in a discharge direction.

A printer that includes a platen, a head, a support plate, and an absorption body. A print medium is placed on the platen. The head includes a nozzle surface and is configured to discharge ink, in a discharge direction, from the nozzle surface. The support plate is configured to support the head. The absorption body is provided on the discharge direction of the support plate. The absorption body is exposed to the platen and is configured to absorb liquid.

A textile printing system for digital printing of colored images onto typically colored fabrics, digitally using print nozzles or other digital means, the nozzles printing print pixels onto the fabrics. The system comprises a print file defining pixel colors for the individual printing pixels; and a deletion unit which deletes print pixels from the print file wherever a respective pixel color is within a threshold distance of the fabric color. The textile printer then prints the print pixels onto the fabric to form a colored image without printing any of the deleted pixels.
