US Patent:

50859625, Feb 4, 1992

Filed:

May 25, 1990

Appl. No.:

7/528516

Inventors:

Muhammad Aslam - Rochester NY
Thomas J. Farnand - Webster NY

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

G03G 1320
G03G 1520

US Classification:

430 99

Abstract:

A toner image, for example, a multicolor toner image is formed on a thermoplastic layer on a receiving sheet. To fix the image without substantial visible objectionable relief, the toner image is first positioned between two members, one of which has a rough texture to it to apply a texture to the toner image and the thermoplastic layer carrying it. It is then positioned between a pair of smooth surfaced pressure members to reduce the texture and relief and to apply a gloss to the image.

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

G03G 1320

US Classification:

430 99

Abstract:

A toner image is carried on a receiving sheet which receiving sheet includes a heat softenable outer layer. The image is fixed or finished by being fed between a pair of pressure members. The pressure members either embed the toner in the layer or apply a gloss or texture to the heat softenable layer. To eliminate an image defect at the leading edge of the sheet, coating of the sheet with the heat softenable layer is terminated one-eighth of an inch prior to the edge of the sheet.

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

G03G 1520

US Classification:

355290

Abstract:

A toner image is fixed to a receiving sheet by the application of pressure and heat applied between first and second pressure members. To prevent blistering of finished receiving sheets, a substantial temperature gradient is maintained between the two members which heats the image side of the receiving sheet adequately for fixing without excessively heating the overall sheet. The second pressure member contacting the side of the sheet opposite from the image is actively cooled by an air cooling device or the like as controlled by a logic and control in response to the temperature of the second pressure member.

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

G03G 1314

US Classification:

430 13

Abstract:

A toner image carrying thermoplastic layer on a receiving sheet is texturized from the back side of the sheet by positioning the sheet between a smooth hard surface and a texturizing surface with the texturizing surface contacting the back side. The thermoplastic layer is softened by heat and becomes texturized without embossing the back side. A curl preventing layer on the back side is not embossed because it has a melting point above the temperature of the process. A glossy-textured print can be produced this way. The process is especially useful in making multicolor prints of photographic quality.

Assignee:

International Classification:

G03G 1316

US Classification:

430 45

Abstract:

A dry toner image is embedded in a thermoplastic layer on a receiving sheet by pressing a ferrotyping web against the image in the presence of sufficient heat to soften the layer. Preferably, the layer is preheated and the web and image are pressed together by a pair of hard rollers to a pressure in excess of 100 pounds per square inch. A curl preventing layer opposite thermoplastic layer does not offset on a backing roller because it has a melting point above the temperature of the process.

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

B32B 300

US Classification:

428195

Abstract:

A dry toner image is fixed to a thermoplastic layer on a receiving sheet by pressing a ferrotyping web against the image in the presence of sufficient heat to soften the layer. A curl preventing layer opposite the thermoplastic layer does not offset on a backing roller or the like because it has a melting point that is high compared to the thermoplastic layer.

Appl. No.:

7/754490

Inventors:

Thomas J. Farnand - Webster NY
Muhammad Aslam - Rochester NY
John P. Swapceinski - Bergen NY
Thomas W. Mort - Rochester NY

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

G03G 1520

US Classification:

355290

Abstract:

A toner image carried by a heat softenable layer of a receiving sheet is fixed by feeding it into a pressure nip between a pressure member and a ferrotyping belt. To preheat the heat softenable layer, it is urged against the belt by a pressure or squeegee roller which contacts the back of the receiving sheet and urges it into contact with the belt. The adhesive characteristics of the heat softenable layer when heated by the belt cause the receiving sheet to follow the belt from the squeegee roller into the pressure nip.
