Abstract

[Problem] To provide a method for manufacturing printed matter having a printed layer that is removable from a substrate but does not easily peel off from the substrate. [Solution] This method for manufacturing printed matter comprises: a base layer formation step; a printed layer formation step; a printing quality confirmation step; and a post-processing step. In the base layer formation step, a base layer that is removable from a substrate is formed on a surface of the substrate. In the printed layer formation step, a printed layer is formed on a surface of the base layer opposite to the substrate. In the printing quality confirmation step, the quality of the printed layer is confirmed. In the post-processing step, depending on the quality of the printed layer, a coating layer is formed to cover the printed layer, or the printed layer is removed from the substrate together with the base layer.

Abstract

Provided is a foil transfer device which transfers foil to a long medium and is capable of suppressing variations in tension of the medium when the foil is transferred. In the foil transfer device 1, foil transfer rollers 29 and 30, constituting a transfer roller pair 7 for pressing a foil transfer sheet 3 against a medium 2 to which an adhesive has been applied to transfer the foil to the medium 2, are driven rollers that rotate following the medium 2 conveyed by a medium conveying mechanism 6. The motor of a medium winding mechanism 34, which winds the medium 2 to which the foil has been transferred, is driven regardless of whether the medium conveying mechanism 6 is conveying the medium when the foil is transferred to the medium 2. In the medium winding mechanism 34, a torque limiter disposed in the power transmission path from the motor to a roll-shaped medium 33 causes the motor to idle with respect to the roll-shaped medium 33 when the torque transmitted from the motor to the roll-shaped medium 33 exceeds a predetermined value.

Abstract

The present invention appropriately enhances the quality of printing. Provided is a method for generating ejection position data indicative of an eject position at which ink is ejected, wherein an edge detection process (S202), an edge correction process (S204), and an ejection position data generation process (S110) are carried out on the basis of data to be processed that indicates an image to be printed. In the data to be processed, pixel values are each set as either a non-ejection value which indicates that ink is not ejected at the corresponding eject position, or an ejection value which is a value other than the non-ejection value. In the edge detection process, an edge is detected by detecting positions at which pixels with non-ejection values are adjacent to pixels with ejection values. In the edge correction process, for at least some of the eject positions at which ink is to be ejected for drawing the edge, pixel values of the corresponding pixels are changed to non-ejection values.

A shaping apparatus 1 comprises an inkjet head 20 that forms one shaping layer by performing a plurality of times a main scanning operation in which ink droplets that will be cured according to light of a predetermined wavelength are ejected toward a shaping table 16 while reciprocating in a main scanning direction; a light source 22 that is provided in at least one position on the front side in the forward path direction or return path direction of the main scanning operation with respect to the inkjet head 20 and that radiates light onto the ink dots formed by the ink droplets; and a flattening unit 23 that flattens the upper surface of the ink dots, wherein a shaped object 30 is formed by layering the shaping layers. In the shaping apparatus 1, during at least one main scanning operation from among a plurality of main scanning operations, the ON/OFF state of the light source or illuminance thereof is controlled, so that a flattening roller 23 flattens the ink dots in the return movement while the ink dots are not yet completely cured.

Abstract

To favorably form the unit layers of a three-dimensional object even when droplet discharge failures or the like have occurred. This three-dimensional object production method includes: a step wherein different regions of a nozzle line (22) are allocated to each of a prescribed number n (n being an integer equal to or greater than 2) of pixel groups (25A, 25B) into which the pixel rows that constitute a unit layer (25) have been divided; and a step wherein the pixel rows are formed as a result of nozzles (21) in each region forming one pixel group (25A, 25B).

Abstract

The present invention improves the printing quality of a multipass printing apparatus. Scanning to form dots by irradiating light after photocurable ink droplets have landed on a print medium 101 and curing the ink droplets is performed multiple times with respect to a specified unit region, alternating between the outgoing path direction and the returning path direction. The time from the landing of the ink droplets on the print medium 101 until curing differs between the outgoing path direction and the returning path direction. Among the multiple scans, in the scan in which the surface layer of a unit region is formed, a discharge control section 10 controls the discharge of ink droplets so that the ink droplets do not combine with each other in the surface layer discharged on the print medium 101.

Abstract

To perform nozzle checks that are suitable for the production of three-dimensional molded objects. A three-dimensional molded object M production method wherein unit layers (L1, L2, … ) are layered. A nozzle check step is performed before a certain unit layer is formed. In the nozzle check step, at least one portion of nozzles (6) that discharge ink for forming said unit layer are inspected after the beginning of production if said unit layer is a lowermost layer (L1) or after the formation of the unit layer directly below said unit layer if said unit layer is not the lowermost layer (L1).
