Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
79 words
An apparatus adapted to produce high gamma images comprising means to apply an imagewise electric field across a manifold set comprising a thin photoresponsive imaging layer sandwiched between a donor substrate and a receiving sheet, said layer being structurally fracturable in response to the combined effect of an applied electric field and exposure to actinic electromagnetic radiation, means to uniformly expose the manifold set to actinic electromagnetic radiation and means to separate the receiving sheet from the donor substrate.
Claim 2
Independent Claim
79 words
An apparatus adapted to produce high gamma images comprising means to apply an imagewise electric field across a manifold set comprising a thin photoresponsive imaging layer sandwiched between a donor substrate and a receiving sheet, said layer being structurally fracturable in response to the combined effect of an applied electric field and exposure to actinic electromagnetic radiation, means to uniformly expose the manifold set to actinic electromagnetic radiation and means to separate the receiving sheet from the donor substrate.
Claim 3
Dependent Claim
38 words
The apparatus of claim 1 further including means to apply an activator liquid to the imaging layer at the interface thereof with the receiver sheet and means to close the manifold set and squeegee out excess activator fluid.
