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.
Claims19
A printing device, comprising:
- a transfer roller to receive printing fluid;
- and
- a processor to control heating of the transfer roller to a predetermined temperature, wherein the predetermined temperature allows the printing fluid to maintain a wet state when transferred from the transfer roller to a print substrate including a textile material, the wet state corresponding to a state in which unevaporated carrier liquid in the printing fluid is allowed to penetrate into fibers of the textile material.
A non-transitory computer-readable medium storing instructions to cause one or more processors to:
- receive information identifying a type of print substrate;
- determine a temperature of a transfer roller based on the information;
- and
- automatically control heating of the transfer roller to the temperature during execution of a print job on the print substrate, wherein the print substrate includes textile material and wherein the temperature allows printing fluid on the transfer roller to maintain a wet state when transferred from the transfer roller to the print substrate, the wet state corresponding to a state in which unevaporated carrier liquid in the printing fluid is allowed to penetrate into fibers of the textile material.
