Embodiment Construction

[0028] Embodiments of the present invention will be described below, but these embodiments are illustrative, and various modifications are of course possible without departing from the technical idea of ​​the present invention. It should be noted that the same components are denoted by the same symbols.

[0029] figure 1 It is a sectional structural view showing an embodiment of the inkjet printer of the present invention.

[0030] exist figure 1 In, symbol 10A represents the inkjet printer of the present invention. The inkjet printer 10A is an inkjet printer for aqueous ink that forms an image by ejecting aqueous ink onto a strip-shaped printing substrate 12, and includes a transport mechanism 14 (in the illustrated example, transport mechanisms 14a and 14b), It carries out the continuous conveyance of the strip-shaped printing substrate 12; the single-channel inkjet heads 16a-16e spray ink on the surface of the strip-shaped printing substrate 12 conveyed by the conveying ...

Abstract

Provided are: an inkjet printer which is configured to be capable of preventing ink flow, color blur, and color mixing during multicolor printing, at the time of performing image formation, by use ofan aqueous ink, on a web-shaped printing base material; and an inkjet printing method using the same. The inkjet printer, which performs image formation by discharging an aqueous ink onto a web-shapedprinting base material, is provided with: a conveyance mechanism which performs continuous conveyance of the web-shaped printing base material; a single-pass-method inkjet head which discharges, witha single-pass method, the aqueous ink onto a surface of the web-shaped printing base material conveyed by the conveyance mechanism; and a surface pre-heating unit which is provided at the conveyanceupstream side relative to the inkjet head and which heats at least the surface of the web-shaped printing base material, wherein image formation is performed, by the inkjet head, on the web-shaped printing base material heated by the surface pre-heating unit.

Description

technical field [0001] The present invention relates to an inkjet printer for performing single pass image formation on a tape-shaped printing substrate using aqueous ink, and an inkjet printing method using the inkjet printer. Background technique [0002] Conventionally, when inkjet printing is performed on a printing substrate by an inkjet printer using aqueous ink, it has been proposed to perform printing while heating the conveyed printing substrate (Patent Document 1). [0003] When heating the printed base material conveyed in this way, the back surface of the printed base material is heated with a heating plate or the like. [0004] However, in the case of heating the back of the printing substrate with a heating plate, etc., and printing while continuously conveying the printing substrate, when the printing speed reaches about 15m / min, there are reasons such as insufficient drying of the ink. Problems such as ink flow or color bleeding, and color mixing during mult...
