Abstract
In one example, a process to solidify a water-based printing fluid printed on a substrate includes flushing nonvolatile solvent in the printing fluid into the substrate with the water in the printing fluid.
Claims12
A printing process for a liquid ink that includes a colorant, water, and a nonvolatile solvent, the process comprising:
- printing the ink on an absorbent substrate;
- and
- absorbing at least 80% of the nonvolatile solvent into the substrate without actively removing water from the substrate.
A printing process for a liquid ink that includes a colorant, water, and a nonvolatile solvent, the process comprising:
- printing the ink on an absorbent substrate;
- and
- heating the printed substrate to at least 70° C. in less than 1 second without blowing hot air over the printed substrate.
A printing process for a liquid ink that includes a colorant, water, and a nonvolatile solvent, the process comprising:
- printing the ink on an absorbent substrate sheet;
- and
- holding the printed substrate sheet at room temperature for at least 40 seconds immediately after printing.
