Fountain solution imaging using dry toner electrophotography

A device for making a fountain solution latent image, comprising:

• a charge retentive surface having an unfused toned electrostatic pattern of toner particles adhered thereto via electrophotography;
• a transfer substrate adjacent the charge retentive surface and forming a nip therebetween, the transfer substrate configured to sandwich the unfused toned electrostatic pattern of toner particles and fountain solution against the charge retentive surface at the nip;
• and
• the charge retentive surface and the transfer substrate separated downstream the nip, wherein upon the separation the unfused toned electrostatic pattern of toner particles remains on the charge retentive surface only and the transfer substrate remains wetted with the fountain solution patterned as the fountain solution latent image based on the electrostatic pattern, wherein the fountain solution latent image is a negative of the electrostatic pattern.

A system for making a fountain solution latent image, comprising:

• a processor and a memory, the memory storing instructions to cause the processor to perform:
• generating an unfused toned electrostatic pattern of toner particles on a charge retentive surface;
• sandwiching the unfused toned electrostatic pattern of toner particles and fountain solution at a nip between the charge retentive surface and a transfer substrate, the transfer substrate being wetted with the fountain solution;
• and
• separating the charge retentive surface from the transfer substrate downstream the nip, wherein upon the separation the unfused toned electrostatic pattern of toner particles remains on the charge retentive surface only and the transfer substrate remains wetted with the fountain solution patterned as a fountain solution latent image based on the electrostatic pattern, wherein the fountain solution latent image is a negative of the electrostatic pattern.
