Abstract
The present disclosure is drawn to an ink set, which can include an ink composition and a fixer composition. The ink composition can include from 2 wt % to 8 wt % pigment, from 0.1 wt % to 0.5 wt % dye, from 2 wt % to 10 wt % polyurethane, and an aqueous ink vehicle. The fixer composition can include from 3 wt % to 15 wt % divalent metal salt, and an aqueous fixer vehicle.

6 more elements
A printing system, comprising:
- an ink composition, including from 2 wt % to 8 wt % pigment, from 0.1 wt % to 0.5 wt % dye, from 2 wt % to 10 wt % polyurethane, and an aqueous ink vehicle;
- a fixer composition, including a fixing agent including from 3 wt % to 15 wt % divalent metal salt, and an aqueous fixer vehicle;
- and
- a corrugated print medium including a corrugated flute with peaks that support a printing substrate coated with an ink-receiving layer.
1 more element
A method of printing, comprising:
- applying a fixer composition on an ink-receiving layer of a corrugated print medium, the fixer composition comprising a fixing agent including from 3 wt % to 15 wt % divalent metal salt and an aqueous fixer vehicle, the corrugated print medium comprising a corrugated flute with peaks that support a printing substrate coated with the ink-receiving layer;
- jetting an ink composition on the ink-receiving layer and in contact with the fixing agent, wherein the ink composition includes from 2 wt % to 8 wt % pigment, from 0.1 wt % to 0.5 wt % dye, from 2 wt % to 10 wt % polyurethane, and an aqueous ink vehicle;
- crashing the pigment and the polyurethane with the divalent metal salt on the ink-receiving layer;
- and
- allowing the dye to spread on the ink receiving layer while the pigment and the polyurethane are crashing.
