Claims
- 1. An apparatus for exposing and developing an imaging web having an image area and a border area, said imaging web including a support having a layer on the surface thereof of photosensitive microcapsules including an internal phase of a photohardenable photosensitive composition and a color former, comprising:
- a source of actinic radiation for uniform exposure of said border area of said imaging web to harden said photosensitive microcapsules;
- means for preventing said source of actinic radiation from exposing said image area of said imaging web; and
- pressure application developer means.
- 2. The apparatus of claim 1 wherein said source of actinic radiation provides actinic radiation selected from the group consisting of ultraviolet radiation, infrared radiation, visible light, X-ray, and ion beam irradiation.
- 3. The apparatus of claim 2 wherein said source of actinic radiation provides visible light.
- 4. The apparatus of claim 1 wherein said means for preventing said source of actinic radiation from exposing said image area of said imaging web comprises a receiver sheet positioned in contact with said image area.
- 5. The apparatus of claim 1 wherein said pressure application developer means is a pair of pressure rollers.
- 6. The apparatus of claim 1 wherein said means for preventing said source of actinic radiation from exposing said image area of said imaging web comprises a baffle having a U-shaped cross-section which is placed over said border area with its open end adjacent thereto and prevents said source of actinic radiation which is disposed within said baffle from exposing said image area.
- 7. An apparatus for exposing and developing an imaging web, said imaging web including a support having a layer on the surface thereof of photosensitive microcapsules including an internal phase of a photohardenable photosensitive composition and a color former, comprising:
- a first source of actinic radiation for image-wise exposure of said photosensitive microcapsules of said imaging web such that an image area is formed, said exposure defining a border area in said web comprising the areas of said imaging web surrounding said image area;
- a second source of actinic radiation for uniform exposure of said border area of said imaging web to harden said microcapsules;
- means for preventing said second source of actinic radiation from exposing said image area of said imaging web; and
- pressure application developer means.
- 8. The apparatus of claim 7 wherein said first and second sources of actinic radiation provide actinic radiation selected from the group consisting of ultraviolet radiation, infrared radiation, visible light, X-ray, and ion beam irradiation.
- 9. The apparatus of claim 8 wherein said first and second sources of actinic radiation provide visible light.
- 10. The apparatus of claim 7 wherein said means for preventing said second source of actinic radiation from exposing said image area of said imaging web comprises a baffle having a U-shaped cross-section which is placed over said border area with its open end adjacent thereto and prevents said second source of actinic radiation which is disposed within said baffle from exposing said image area of said imaging web.
- 11. The apparatus of claim 7 wherein said pressure application developer means is a pair of pressure rollers.
- 12. The apparatus of claim 7 wherein said means for preventing said second source of actinic radiation from exposing said image area of said imaging web comprises a receiver sheet positioned in contact with said image area.
