A thermal transfer printer containing a means for feeding a plurality of thermal transfer sheets and a plurality of image receiving sheets, a platen roller placed in the feeding path of the thermal transfer and image receiving sheets, and a recording section with a thermal head with a plurality of heating resistors for selective activation based upon image data to record the image on the image receiving sheets when they and the thermal transfer sheets are forced together by the platen roller so each image receiving sheet is pressed on the thermal head surface by the platen roller. The recording section also has a means to detect when at least one of the thermal transfer and image receiving sheets being recorded are out and a means automatically to exchange the thermal transfer or image receiving sheets with new sheets based upon the detected result.

A thermal transfer sheet is comprises a substrate sheet, a dye layer of at least one color, a white layer to cover an image-receiving portion of a receiving material after an image is formed therein, and if necessary, a transferable receptor layer to be transferred to the image-receiving portion of the receiving material before the formation of the image, those layers being alternately disposed side by side on a surface of the substrate sheet, wherein said white layer being capable of adhering to the image-receiving portion already provided with the image and being disposed on the substrate sheet via a peeling layer interposed therebetween. The white layer has a white screenability to provide excellent light diffusivity and light transmissivity for a background of the printed image. The white layer may be formed by applying a coating liquid containing an adhesive binder resin and a white pigment or a coating liquid containing a binder resin, an adhesive, and a white pigment on the peeling layer.

Thermal transfer sheet and method for manufacturing same

Provided is two kind of thermal transfer sheets comprising a substrate and a white transfer layer, the white transfer layer being to be transferred onto an image-formed portion of an image-receiving sheet. In the one kind, white transfer layer includes a white ink layer containing a white pigment and/or a filler, and has a total light transmittance of 30 to 95% and a haze of 30 to 95% due to the white ink layer. In another kind, the white transfer layer includes a white ink layer and a peeling layer, the white ink layer containing a white pigment and/or a filler, the peeling layer laminated between the white ink layer and the substrate, and capable of causing a cohesive failure thereby converting into an irregular surface of a printed material through a transferring process. The present invention also provides printed materials by the using of the thermal transfer sheets described above and recording methods for producing of the printed materials. The printed material can be used as an electric-decorating display member.

Thermal transfer sheet, image-printed material and recording method

A photographing box is arranged to reduce a time taken from photographing an object to printing the image of the object. The photographing box is intended to be manufactured at low cost and more easily maintained. The photographing box includes a photographing mechanism house for housing a photographing mechanism and a photographing space section. If paid, the photographing device is operated to illuminate an object, photograph the object, and do some image processing like image magnification or reduction or image layout. Plural images sized for different uses are output on one cut sheet by a sublimation transfer printer. The photographing box operates to print out the image at high speed, and is manufactured at low cost and more easily maintained.

The present invention aims to provide a thermal transfer image-receiving sheet which does not suffer from any cockle problem, during printing, associated with a printer or a dye transfer film used. The thermal transfer image-receiving sheet comprises a substrate sheet and, provided on at least one surface thereof in the following order, an intermediate layer and a receptive layer, the intermediate layer containing either an acrylic polyol or cellulose acetate butyrate. Further, the present invention provides a thermal transfer image-receiving sheet which has a capability of preventing curling and causes no damage to an image-receiving surface even when image-receiving sheets put on top of each other or one another are used. This thermal transfer image-receiving sheet comprises a back surface layer provided on a substrate sheet in its surface where no image is to be formed, the back surface layer containing an acrylic polyol.

Thermal transfer image-receiving sheet

An image-receiving sheet for thermal transfer printing, comprises a substrate and a receptor layer provided on at least one surface of the substrate. The receptor layer is formed by applying a receptor layer forming composition comprising (a) at least one kind of thermoplastic resin and (b) at least one kind of release agent selected from silicone compounds expressed by the following formula (1):

Image-receiving sheet for thermal transfer printing and method for

A thermal transfer image-receiving sheet comprising a substrate sheet, a dye-receptive layer provided on at least one surface of the substrate sheet, and a backing layer provided on the other surface of the substrate sheet, wherein the dye-receptive layer contains polycaprolactone.

There is provided a thermal transfer image-receiving sheet comprising: a substrate sheet; and a receptive layer provided on at least one side of the substrate sheet, the receptive layer being formed of a receptive layer-constituting resin containing an ethylene terpolymer selected from an ethylene/vinyl acetate/polar group-containing monomer terpolymer and an ethylene/acrylic ester/polar group-containing monomer terpolymer.

There is provided a thermal transfer image-receiving sheet comprising: a substrate sheet; and an image-receiving layer provided on one side of the substrate sheet, the image-receiving layer comprising a copolymer, having an average degree of polymerization of 800 to 2000, of at least vinyl chloride and vinyl acetate as main comonomers.

A medical image forming method including, the steps of superposing a three-primary-color thermal transfer sheet and an image receiving sheet, the thermal transfer sheet having a base film and three color dye layers of yellow, magenta, and cyan, each of the dye layer; being composed of a dye and a binder, the image receiving sheet having a dye accepting layer heating the rear surface of the thermal transfer sheet with a heating device in an image shape; and driving and controlling the heating device with a control unit so as to form a full color image on the image receiving sheet. The control unit is adapted to compensate tones of the image so that chromaticity values thereof formed on the image receiving sheet are in a region defined by four points of (a*=0, b*=0), (a*=20, b*=-5), (a*=18, b*=15), and (a*=0, b*=15) when an achromatic color signal is input and L*=80. According to an aspect of the present invention, the control unit is adapted to compensate tones of three primary colors so that the density graduation of light red of an image in accordance with a light red signal sent to the control unit becomes high and thereby the low density region (light region) of the image formed in accordance with a achromatic color signal becomes reddish. According to another aspect of the present invention, since the dye layers are formed so that the light region becomes reddish and the dark region greenish, images where colors from light orange to light red can be easily distinguished are formed.
