Abstract
A liquid electrophotographic (LEP) printing device that includes a photo-imaging plate (PIP) to receive a liquid printing fluid, the liquid printing fluid including a pigment incorporated into a resin, a charge conductor, and a carrier liquid, and a transfer roller to transfer the liquid printing fluid from the PIP to a fabric substrate while wet.
Claims17
A liquid electrophotographic (LEP) printing device comprising:
- a photo-imaging plate (PIP) to receive a liquid printing fluid, the liquid printing fluid comprising:
- a pigment incorporated into a resin;
- a charge conductor;
- and
- a carrier liquid;
- and
- a transfer roller to transfer wet liquid printing fluid from the PIP to a fabric substrate while preventing evaporation of the carrier liquid, such that at most 10% of the carrier liquid is evaporated on the transfer roller before transfer of the liquid printing fluid to the fabric substrate.
4 more elements
A system for printing onto fabric, the system comprising:
- a printing fluid source comprising a printing fluid, the printing fluid comprising, at least, a carrier fluid;
- and
- a heat adjustable transfer roller to:
- receive an amount of printing fluid from a photo imaging plate;
- transfer the printing fluid as a wet printing fluid to the fabric while preventing the carrier fluid from evaporating such that at most 10% of the carrier liquid is evaporated on the transfer roller before transfer of the liquid printing fluid to the fabric substrate;
- and
- a processor to, based on received input, determine a temperature to heat the transfer roller to during printing.
4 more elements
A method, comprising:
- receiving a wet printing fluid at a photo-imaging plate, the wet printing fluid comprising a level of carrier fluid to be absorbed into fibers of a fabric substrate;
- transferring the wet printing fluid to a transfer roller;
- and
- during printing, preventing evaporation of the carrier fluid such that at most 10% of the carrier fluid is evaporated on the transfer roller before transfer of the wet printing fluid to the fabric substrate.
