摘要：
An image transcription method of transcribing an image of the dye on a printing sheet outputted by e.g., a video printer onto a substrate for transcription, such as a cup of pottery or the like. For transcription, a resin is coated on the surface of the substrate for transcription to form a reception layer. This reception layer is dried in an electrical oven to form a support for transcription. A printing sheet carrying an image of a sublimable dye is stacked on the reception layer of the support for transcription and pressured to the reception layer under application of heat and pressure. As the resin for the reception layer, the acrylic resin or the epoxy resin or both are employed. If the resin composed mainly of the acrylic resin is employed, the viscosity of the resin is set to 43 to 52 seconds in terms of the Ford cup viscosity, and the resin discharge pressure from a spray gun is set to 35 kg/m2±0.01 kg.cm2. The distance between the spray gun and the substrate for transcription is set to 100 mm±5 mm, while the drying temperature is 170 to 180° C. The thickness of the reception layer is 10 to 50 mum. After transcribing the image of the sublimable dye to the reception layer, a transparent film is bonded, if necessary, as a protective film on the reception layer.
技术功效语段：
It is another object of the present invention to provide a method for transcribing a picture and a support for transcription whereby a picture of a sublimable dye can be transcribed in a short time.
By employing an electrical oven for drying the reception layer, precise temperature control becomes possible, such that the reception layer may be prohibited from being discolored and a transcribed image may be produced. Simultaneously, foreign matter may be prohibited from being mixed during drying by a hot air drying oven to prohibit the lowering in the product quality.
By layering and bonding a transparent film such as a film of acrylic resin as a cover coating on the reception layer, the transparent film operates as a protective layer for significantly improving weatherability and resistance against solvents or chemicals.
If the lubricant is deposited in this manner to the printing sheet, lubricity may be accorded to the printing sheet by the lubricant. In addition, when the printing sheet is layered on the support for transcription, such as a mag-cup, air bubbles intruded into the space between the printing sheet and the support for transcription tend to be discharged to outside so that creases are less liable to be produced. Thus a satisfactory image free of non-transcribed portions can be re-transferred to the support for transcription without the necessity of rubbing the printing sheet surface with a spatula.
权利要求：
What is claimed is:
1. An image transcribing method for transcribing an image to a substrate for transcription, comprising:
a step (a) of transcribing a reversed image to a printing sheet using a sublimable ink ribbon;
a step (b) of coating a resin of a reception layer on a substrate for transcription and drying in an oven for turning the substrate for transcription into a support for transcription, said reception layer being formed on an epoxy resin and an acrylic resin in combination formed on the surface of the substrate for transcription, said reception layer being comprised of a first reception layer mainly composed on an epoxy based resin and a second reception layer mainly composed of an acrylic resin stacked on said first reception layer;
a step (c) of transcribing the image once transcribed to said printing sheet to said support for transcription; and
a step (d) of peeling said printing sheet from said support for transcription.
2. The image transcribing method as claimed in claim 1 characterized in that a cup of pottery is used as the substrate for transcription and resin is coated by a spray gun on said cup as said cup is rotated for forming the reception layer.
3. The image transcribing method as claimed in claim 1 characterized in that the temperature for said drying is 170 to 180.degree. C.
4. The image transcribing method as claimed in claim 3 characterized in that the viscosity of the acrylic resin is 43 to 52 seconds in terms of the Ford cup density.

6. The image transcribing method as claimed in claim 1 characterized in that the thickness of the reception layer is set to 10 to 50 .mu.m.
7. The image transcribing method as claimed in claim 1 further comprising a step of bonding a transparent film on said reception layer after transcribing the image of the sublimable dye to said reception layer.
8. The image transcribing method as claimed in claim 7 characterized in that the transparent film is an acrylic film.
9. The image transcribing method as claimed in claim 7 characterized in that said transparent film contains a UV ray absorber.
10. The image transcribing method as claimed in claim 7 characterized in that said transparent film is embossed.
11. The image transcribing method as claimed in claim 7, characterized in that said transparent film is embossed.
12. The image transcribing method as claimed in claim 1 having, subsequent to step (b), a step of transcribing a lubricant-containing layer formed in said sublimable ink ribbon to said printing sheet.
13. The image transcribing method as claimed in claim 1 further comprising, subsequent to said step (b), a step of bonding a transparent film on said reception layer.
14. The image transcribing method as claimed in claim 1, characterized in that it comprises an initial step of reversing the image to be transcribed.
15. The image transcribing method as claimed in claim 1, characterized in that the step (c) further comprises stacking of the printing sheet on the reception layer and pressuring the printing sheet onto the reception layer under heat.
16. The image transcribing method as claimed in claim 1, having, subsequent to said step (a), a step of transcribing a lubricant-containing layer formed in said sublimable ink ribbon to said printing sheet.
17. The image transcribing method as claimed in claim 1, further comprising, subsequent to said step (c), a step of bonding a transparent film on said reception layer.
