When a print data creation program is executed by a computer, the computer performs the following processing. The computer acquires image data representing a print image from a storage. The computer divides the print image represented by the acquired image data into a plurality of divided images of a desired resolution. The computer creates print data to be printed by a print device, from at least one of the plurality of divided images.

A print device is provided with a background head that discharges a background ink onto a recording medium, a color head that discharges a color ink onto the recording medium, and a CPU that controls the background head and the color head. The CPU of the print device divides the background ink into a plurality of layers including a first background layer and a second background layer, and discharges the background ink from the background head. A first discharge region of the first background layer is further to an inner side than a second discharge region of the second background layer.

An image forming method includes a step of applying a pretreatment liquid containing an aggregating agent (D) and water (E) onto a base material and a step of forming an image by applying an ink containing water (A), a resin (B), and an organic solvent (C) satisfying Expression (1) onto the pretreatment liquid applied onto the base material, in which in a region to which the ink has been applied, C.sub.C which is the number of grams of the organic solvent (C) to be applied per area of 1 m.sup.2 and C.sub.D which is the number of grams of the aggregating agent (D) to be applied per area of 1 m.sup.2 satisfy Expression (2). SP.sub.B represents an SP value (MPa.sup.1/2) of a main resin in the resin (B), SP.sub.C represents an SP value (MPa.sup.1/2) of the organic solvent (C), and |SP.sub.C−SP.sub.B| represents an absolute value of a difference between SP.sub.C and SP.sub.B.

|SP.sub.C−SP.sub.B|≤10.0  Expression (1)

0.10≤C.sub.C/C.sub.D≤2.90  Expression (2)

Disclosed is a carriage for a direct to garment inkjet printing machine. The machine has a frame having a leading edge, a trailing edge, and a pair of opposed lateral edges. A first row of slots is positioned on the leading edge and a second row of slots is positioned on the trailing edge. The second row of slots is spaced from the first row of slots by a gelling gap. A shelf on the frame supports tanks of white ink and tanks of color ink and a first plurality of tubing connects a tank of white ink positioned on the shelf with a print head in the first row of slots. A second plurality of tubing is for connecting a tank of color ink positioned on the shelf with a print head in the second row of slots. A pair of side heaters attached to opposed lateral edges of the first frame.

An inkjet printer includes a first light applicator disposed in a second scanning direction relative to a recording head. The first light applicator includes a first upstream light source group at a location corresponding to a location of the recording head in a movement direction of a recording medium, and a first downstream light source group on a downstream side in the movement direction of the recording medium relative to the recording head. The inkjet printer turns off the first upstream light source group and turns on the first downstream light source group during movement of a carriage in a first scanning direction and discharge of first ink from the recording head, and turns on the first upstream light source group and the first downstream light source group during movement of the carriage in the second scanning direction after discharge of the first ink.

Provided are a fiberboard structure manufacturing method, a fiberboard structure manufacturing system, and a fiberboard structure, in which preferred inkjet type printing on a substrate to which a fiberboard is applied is implemented. A fiberboard structure manufacturing method includes: applying an aqueous sealer to a first surface of a substrate in which a fiberboard is used; forming an undercoat layer in which the aqueous sealer is dried, on the first surface; applying an aqueous preconditioning liquid having a function of thickening an aqueous ink to the first surface on which the undercoat layer is formed; and jetting the aqueous ink from an inkjet type jetting head to apply the aqueous ink to the first surface on which the aqueous preconditioning liquid is applied.

On a carriage that is transported in a main scanning direction by a main scanning drive portion heads are disposed so as to be displaced from each other in a sub-scanning direction, and heads are disposed so as to be displaced from each other in the sub-scanning direction. Therefore, even when an ejection failure occurs in nozzles of one of the two heads and in nozzles of one of the two heads ink can be ejected from the other head that ejects the same type of ink in main scanning. Thus, even when the ejection failure occurs in the nozzles, a deterioration in print quality can be suppressed.

DOD ink delivery systems and methods are described herein that are used in DOD card printing systems of card processing systems for supplying ink for DOD printing on plastic cards of the type that bear personalized data unique to the intended cardholder and/or which bear other card information. The DOD ink delivery system is configured to recirculate the ink, or have a second pressure damper container that provides damping to eliminate large and abrupt spikes in ink pressure which can disturb the meniscus of the ink in each nozzle of the print head generated by a vacuum system, or simultaneously operate a supply pump at a lower flow rate than a return pump during an autofill/autodrain procedure on the ink delivery system.

An aqueous white ink jet ink composition is provided for printing in which a treatment liquid containing a flocculant is applied onto a poorly absorbent or non-absorbent printing medium. The white ink composition contains a white pigment, a nonionic dispersant adapted to disperse the white pigment, and a fixing resin.

A printer is provided with a front linear guide rail, a front linear guide block, a rear linear guide rail, a rear linear guide block, and a carriage. The front linear guide rail extends in a first direction. The front linear guide block is configured to move along the front linear guide rail. The rear linear guide rail is provided in a second direction with respect to the front linear guide rail, and extends in the first direction. The rear linear guide block is configured to move along the rear linear guide rail. The carriage is fixed to the front linear guide block and the rear linear guide block. One of the front linear guide block and the rear linear guide block positions the carriage in the second direction, and the other positions the carriage in a third direction.
