Definitions

  • the present invention relates to a printing method, a transfer material, and an inkjet discharge device, and more particularly, to a transfer printing method, and a transfer material and inkjet discharge device used in the printing method.
  • a printing method whereby adhesive is inkjetted and thereby applied, in a pattern intended to be transferred, to one of a transfer material or a transferring medium, and the transfer material and transferring medium are pressed against each other, thus transfer printing a transfer layer of the transfer material on the transferring medium (refer to JP-A-2005-501761 ).
  • an adhesion layer formed from an aggregate of relatively large jetting droplets is such that, as an incline ⁇ of an interface 107b of a peripheral portion 107a of an adhesion layer 107 of a transfer material 103 is gradual, as shown in Fig. 9 , the contact between a transfer layer 106 and the adhesion layer 107 in the peripheral portion 107a is unstable, and it is thus difficult to obtain a high-definition transfer image.
  • each droplet (of adhesive 107A) jetted as an inkjet droplet is shown by an alternate long and short dash line, and the outline of the adhesion layer 107 formed by the adhesive 107A jetted as inkjet droplets being fixed as an aggregate is shown by a solid line, on the transfer layer 106 in Fig. 9 .
  • the invention having been contrived bearing in mind the heretofore described problems, has an object of providing a printing method whereby it is possible to speed up steps, and it is possible to obtain a high-definition transfer image.
  • a printing method disclosed includes forming an adhesion layer using a printing whereby adhesive is inkjetted, in a pattern intended to be transferred, onto a transfer layer of a transfer material in which the transfer layer is provided on a base material, or onto a transferring medium; stacking and pressing so that the adhesion layer is sandwiched by the transfer material and transferring medium; and transferring the transfer layer to the transferring medium in the pattern intended to be transferred.

Consequently, it is possible to form the adhesion layer at high speed, and obtain a high-definition transfer image. Furthermore, it is also possible to easily carry out a control of the film thickness of the adhesion layer when adding the adhesive to a region in which the film thickness decreases.
  • the adhesive when forming the adhesion layer, is printed on a peripheral portion of the adhesion layer in a smaller jetting amount than on other than the peripheral portion, and at closer jetting intervals than on other than the peripheral portion. According to this, by making the jetting intervals closer in the peripheral portion and thus increasing resolution, it is possible to form a high-definition adhesion layer at high speed. Inkjet droplets (the adhesive) may or may not be overprinted on the peripheral portion.
  • the adhesive when forming the adhesion layer, the adhesive is printed in plural batches on the peripheral portion of the adhesion layer, and second and subsequent printings are carried out over a region on which a first printing has been carried out. According to this, by carrying out the second and subsequent printings over a peripheral portion of a pattern intended to be transferred, on which the first printing has been carried out, the film thickness of an adhesion layer interface increases, and it is thus possible to realize a stable transfer at an adhesion layer boundary too.
  • the adhesive when forming the adhesion layer, the adhesive is printed in plural batches on the peripheral portion of the adhesion layer, and the second and subsequent printings are carried out, with an adhesive jetting amount smaller than that in the first printing, over the region on which the first printing has been carried out.

  • adhesion layer when forming the adhesion layer, adhesive to which a filler is added is used. According to this, it is possible to form an adhesion layer to which a filler is added. Consequently, a deformation of the adhesion layer when transferring is prevented, and it is thus possible to obtain a high-definition transfer image.
  • a transfer material disclosed is used in the heretofore described printing method.
  • the adhesion layer, as well as being provided on the transfer layer, is formed from the adhesive jetted by switching between at least two or more stages.

  • An inkjet discharge device disclosed being used in the heretofore described printing method, includes an inkjet head which jets the adhesive as inkjet droplets; and a controller which controls the action of the inkjet head.
  • the controller when forming the adhesion layer, switches the adhesive jetting amount between at least two or more stages. According to this, as it is possible, when forming the adhesion layer, to switch the adhesive jetting amount between at least two or more stages, it is possible to form the adhesion layer at high speed, and it is possible to obtain a high-definition transfer image.

Furthermore, it is also possible to easily carry out a control of the film thickness of the adhesion layer 7 when adding the adhesive to a region in which the film thickness decreases.
  • the adhesive when forming the adhesion layer 7, the adhesive is printed on a peripheral portion 7a of the adhesion layer 7 in a smaller jetting amount than on other than the peripheral portion 7a, and at closer jetting intervals than on other than the peripheral portion 7a. According to this, by making the jetting intervals closer in the peripheral portion 7a and thus increasing resolution, it is possible to form a high-definition adhesion layer 7 at high speed. Inkjet droplets (the adhesive) may or may not be overprinted on the peripheral portion 7a.
  • the adhesive is printed in plural batches on the peripheral portion 7a of the adhesion layer 7, and second and subsequent printings are carried out over a region on which a first printing has been carried out. According to this, by carrying out the second and subsequent printings over the peripheral portion of the pattern intended to be transferred, on which the first printing has been carried out, the film thickness of the peripheral portion 7a (particularly, an interface 7b) of the adhesion layer 7 increases, and it is thus possible to realize a stable transfer in a boundary portion of the adhesion layer 7 too.
  • the adhesive when forming the adhesion layer 7, the adhesive is printed in plural batches on the peripheral portion 7a of the adhesion layer 7, and the second and subsequent printings are carried out, with an adhesive jetting amount smaller than that in the first printing, over the region on which the first printing has been carried out.
  • the adhesive by printing (jetting) the adhesive as relatively large droplets in the first printing, and printing (jetting) the adhesive as relatively small droplets, that is, droplets smaller than those in the first printing, on the peripheral portion of the pattern intended to be transferred, the incline of the interface 7b of the adhesion layer 7 increases, and it is thus possible to realize a stable transfer in the boundary portion of the adhesion layer 7 too.
  • adhesion layer 7 adhesive to which a filler is added is used.
  • adhesive to which a filler is added is used. The reason for this is that, by forming an adhesion layer 7 to which a filler is added, a deformation of the adhesion layer 7 when transferring is prevented, and it is thus possible to obtain a high-definition transfer image.
  • a transfer material 3 is used in the printing method.
  • the adhesion layer 7, as well as being provided on the transfer layer 6, is formed from the adhesive jetted by switching between at least two or more stages. According to this, it is possible to realize a stable transfer in the boundary portion of the adhesion layer 7 too, and thus possible to obtain a high-definition transfer image.
  • An inkjet discharge device 1, being used in the heretofore described printing method includes an inkjet head 13 which jets the adhesive as inkjet droplets; and a controller which controls the action of the inkjet head 13.
  • the controller when forming the adhesion layer 7, switches the adhesive jetting amount between at least two or more stages. According to this, as it is possible, when forming the adhesion layer 7, to switch the adhesive jetting amount between at least two or more stages, it is possible to form the adhesion layer 7 at high speed, and it is possible to obtain a high-definition transfer image.
