Image transfer sheet, manufacturing method for image transfer sheet, and image transfer method

Abstract

The present invention provides an image transfer sheet which allows an image having a stereoscopic effect that is characteristic of UV printing to be transferred to objects of a wide variety of materials to which the image is to be transferred, particularly to the surface of a three-dimensional object including a curved surface, with such a finish that the image is directly printed, and which canbe manufactured by a minimum number of steps using a UV printer, a manufacturing method therefor, and an image transfer method using the image transfer sheet. An image transfer method, wherein an image transfer sheet is manufactured by a printing step for providing an image layer by printing ink, by a contactless printer, on the upper surface of a glue layer of a stick-on sheet obtained by peelably forming the glue layer on the upper surface of a release paper, and a pasting step for pasting, on the upper surface of the stick-on sheet on which the image layer has been provided, a transfer filmhaving a release property for the image layer and an easy adhesion property for the glue layer, and only the image layer is transferred to the surface of an object to which an image is to be transferred by a release paper removal step for peeling and removing only the release paper from the image transfer sheet, a pressure bonding step for pressure bonding the lower surface of the glue layer of the image transfer sheet from which the release paper has been removed to the object, and a film peeling step for peeling and removing the transfer film from the image transfer sheet pressure bonded tothe object.

Description

technical field [0001] The present invention relates to an image transfer sheet for transferring an arbitrary image to an object to be transferred, a method for producing the image transfer sheet, and image transfer to an object to be transferred using the image transfer sheet method. Background technique [0002] Techniques such as water transfer printing, thermal transfer printing, sublimation transfer printing, and dry transfer printing are well known as transfer printing for transferring an image to an object to be transferred. Among them, dry transfer is to temporarily bond the image layer on the substrate sheet, apply the adhesive on the back of the image layer, and transfer the image layer to the surface of the transfer object by pressing for bonding. ,This dry transfer printing does not leave any edges on the image during transfer, so it looks like it is directly printed on the transfer target object, and does not require post-processing with a cutter plotter or the...

Problems solved by technology

As a result, although UV printing of an image on a base sheet itself is possible in the prior art, it was confirmed that there is a problem that it is difficult to form an image layer with a three-dimensional effect that is characteristic of UV printing because the original image needs to be printed in mirror image.

In addition, it was found that there were problems such as insufficient volatilization of the glue coated on the image layer, generation of air bubbles between the image layer and the object to be transferred over time after transfer, or fluctuations in the image layer itself.

In addition, in the conventional technology, it is necessary to use a brush or a sponge to apply the glue to the image layer by hand after printing, and there are problems even in terms of work efficiency.
