Abstract
Abstract Information is recorded on the surface of a recording member by signal-controlled non-impact printing means, such as a jet printer or meniscus printer. The recorded information is not necessarily visible, and comprises deposits formed by ion or electron or molecular donor material. The thus-recorded information is detected by pressure contacting the surface of the recording member with a dielectric surface to form a latent image thereon. The latent image may be read or detected as a voltage analog or it may be rendered visible by the attraction thereto of electroscopic marking particles. The deposit formed by such marking particles can be transferred onto a copy sheet or the like.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
136 words
A method of information processing comprising the steps of: (a) printing information in the form of an ink deposit on the surface of a recording member by non-impact technique, said ink deposit containing a donor material which is spontaneously capable of transferring submolecular matter to form a latent image analog on a dielectric surface pressure-contacted thereagainst when said ink deposit is dry; (b) drying said printed ink deposit containing said donor material on said surface of said recording material; (c) pressure contacting said surface of said recording member containing said dried ink deposit thereon with a dielectric surface in order to form a latent image analog on said dielectric surface, said latent image analog being formed by the submolecular matter donated by said donor material; and (d) detecting said latent image analog on said dielectric surface.
Claim 2
Independent Claim
136 words
A method of information processing comprising the steps of: (a) printing information in the form of an ink deposit on the surface of a recording member by non-impact technique, said ink deposit containing a donor material which is spontaneously capable of transferring submolecular matter to form a latent image analog on a dielectric surface pressure-contacted thereagainst when said ink deposit is dry; (b) drying said printed ink deposit containing said donor material on said surface of said recording material; (c) pressure contacting said surface of said recording member containing said dried ink deposit thereon with a dielectric surface in order to form a latent image analog on said dielectric surface, said latent image analog being formed by the submolecular matter donated by said donor material; and (d) detecting said latent image analog on said dielectric surface.
Claim 3
Dependent Claim
18 words
The method of information processing as claimed in claim 1, wherein said donor material is a water-soluble polymer.
Claim 4
Dependent Claim
18 words
The method of information processing as claimed in claim 1, wherein said donor material is a reactive polyamide.
Claim 5
Dependent Claim
19 words
The method of information processing as claimed in claim 1, wherein said donor material is a surface active agent.
Claim 6
Dependent Claim
33 words
The method of information processing as claimed in claim 1, wherein said step (d) comprises forming a visible image deposit on said dielectric surface by depositing electroscopic marking particles on said latent image.
Claim 7
Dependent Claim
28 words
The method of information processing as claimed in claim 5, wherein after said visible image deposit is formed, said electroscopic marking particles are transferred to a transfer-receiving member.
Claim 8
Dependent Claim
33 words
The method of information processing as claimed in claim 6, wherein after said electroscopic marking particles are transferred to a transfer-receiving member said dielectric surface is cleaned to remove any untransferred image deposit.
Claim 9
Dependent Claim
42 words
The method of information processing as claimed in claim 5, wherein said electroscopic marking particles are deposited on said latent image by passing said dielectric surface with said latent image thereon through a tank containing said electroscopic marking particles in liquid suspension.
Claim 10
Dependent Claim
23 words
The method of information processing as claimed in claim 1, wherein said step (d) comprises scanning said dielectric surface with a voltage-sensing means.
Claim 11
Dependent Claim
30 words
The method of information processing as claimed in claim 9, wherein after said dielectric surface is scanned with said voltage-sensing means said latent image is erased from said dielectric surface.
Claim 12
Dependent Claim
16 words
The method of information processing as claimed in claim 1, wherein said latent image is invisible.
Claim 13
Dependent Claim
21 words
The method of information processing as claimed in claim 1, wherein said recording member of step (a) comprises a paper web.
Claim 14
Dependent Claim
24 words
The method of information processing as claimed in claim 1, wherein said dielectric surface comprises a paper web coated with a polyvinyl butyral resin.
Claim 15
Dependent Claim
24 words
