A method for printing on both sides of a roll sheet including superimposing and pressing a thermal transfer sheet and the roll sheet between a platen roller and a thermal head so that the bottom surface of the thermal transfer sheet touches the top surface of the roll sheet and the bottom surface of the roll sheet touches the platen roller, and printing an image on the top surface of the roll sheet while conveying the sheets; and superimposing and pressing a thermal transfer sheet and the roll sheet between a platen roller and a thermal head so that the top surface of the thermal transfer sheet touches the bottom surface of the roll sheet and the top surface of the roll sheet touches the platen roller, and printing an image on the bottom surface of the roll sheet while conveying the sheets.

Duplex printing method, bookbinding method, printer for use in duplex printing method

Image plus event information printing system, which comprises an image data inputting means for inputting a datum of original image, an event information database which memorizes the data of current and/or passing events information being sorted with one or more items, wherein one of the items consists of the occurrence time of the event, an event information retrieval means for extracting any event information within a predetermined range being in correlation to the time which is related to the original image, by retrieving from the sorted data in the event information database with using one or more of the items, an image editing means for preparing a datum of an image plus event information, from the datum of original image and the extracted event information, and a printing means for printing the image plus current events information in accordance with the datum prepared by the image editing means.

Image printing system

Disclosed is a thermal transfer image receiving sheet comprising a substrate sheet, an intermediate layer provided on at least one surface side of the substrate sheet and a dye receptor layer provided on the surface of the intermediate layer, wherein the substrate sheet is a pulp paper, the intermediate layer is formed from an organic solvent solution of a resin, and the dye receptor layer is formed from an aqueous resin liquid. By virtue of this structure, the thermal transfer image receiving sheet can be prevented from occurrence of curling caused by temperature change. Also disclosed is a thermal transfer image receiving sheet comprising a substrate sheet, an intermediate layer provided on at least one surface side of the substrate sheet and a dye receptor layer provided on the surface of the intermediate layer, wherein the intermediate layer is formed from either an acrylic resin or a resin at least a part of which is crosslinked. By virtue of this structure, the thermal transfer image receiving sheet can be excellent in smoothness, strength, cushioning properties and writing properties, and further can give an image of high density and high resolution.

Thermal transfer image receiving sheet

The present invention relates to a heat transfer cover film characterized in that a specific transparent resin layer () is releasably provided on a substrate film (). This transparent resin layer () can be easily laminated on the surface of the resulting image (Y,M andC) by heat transfer means, making it possible to provide expeditious provision of image representations which are improved in terms of such properties as durability, gloss and color development and is curl-free.

Heat transfer cover films

The present invention relates to a heat transfer cover film characterized in that a specific transparent resin layer ( ) is releasably provided on a substrate film ( ). This transparent resin layer ( ) can be easily laminated on the surface of the resulting image ( Y, M and C) by heat transfer means, making it possible to provide expeditious provision of image representations which are improved in terms of such properties as durability, gloss and color development and is curl-free.

The present invention relates to a heat transfer cover film characterized in that a specific transparent resin layer (,) is releasably provided on a substrate film (,). This transparent resin layer (,) can be easily laminated on the surface of the resulting image (,Y,,M and,C) by heat transfer means, making it possible to provide expeditious provision of image representations which are improved in terms of such properties as durability, gloss and color development-and is curl-free.

A heat transfer sheet comprising a polyester film substrate sheet, an adhesive layer formed on one surface of the substrate sheet by applying the adhesive layer to the substrate sheet and biaxially stretching both the layer and the sheet simultaneously, and at least two heat transfer layers formed on said adhesive layer, a first layer comprising a thermally migratable dye and an untransferable binder, and second layer comprising a dyed or pigmented, heat-meltable binder.

The present invention relates to a heat transfer cover film characterized in that a specific transparent resin layer (2) is releasably provided on a substrate film (1). This transparent resin layer (2) can be easily laminated on the surface of the resulting image (7Y, 7M and 7C) by heat transfer means, making it possible to provide expeditious provision of image representations which are improved in terms of such properties as durability, gloss and color development and is curl-free.

For thermal transfer printing, a coloring material image is thermally migrated from a thermal transfer printing sheet having a coloring material layer thereon onto an image forming area of an image-receiving layer of an intermediate transfer recording medium. The image on the recording medium is then thermally transfer-printed under pressure on a printing sheet in an image transfer section. A detection mark is provided on the intermediate transfer recording medium. This detection mark is detected for positioning an image forming area of the recording medium relative to a thermal head of the printer. In a case where the image forming section and the image transfer section are arranged in a line, a buffer unit is provided in which the recording medium being fed continuously between the two sections is caused to take a detouring path whereby mutual influence of the two sections is prevented. A line heater can be used as heating means in the image transfer section.

Method and apparatus for thermal transfer printing

The present invention relates to a heat transfer recording medium in which a substrate has items of information such as an image and characters formed on a surface thereof by heat transfer and a transparent protective layer is provided on at least a part of the surface of the thus recorded information through an adhesive layer, if required, characterized in that the adhesive layer and/or protective layer function to provide security against counterfeiting. Combining information recorded by heat transfer with a function to provide security against counterfeiting, the present invention provides greater security against falsifying or counterfeiting.
