Abstract
The present disclosure is drawn to a coated print medium, a method of preparing a print medium, and a printing system. The coated print medium can comprise a substrate and a coating applied to the substrate. The coating can include, by solids, 20 wt % to 90 wt % of non-film forming polymer particulates having a particle size from 50 nm to 300 nm and a glass transition temperature greater than 85° C.; 1 wt % to 25 wt % water soluble polymer binder; 0.1 wt % to 5 wt % fixing agent; and 0.1 wt % to 10 wt % slip aid.
Claims15
A coated print medium, comprising:
- a substrate;
- a coating applied to the substrate, comprising, by solids:
- 20 wt % to 90 wt % of non-film forming polymer particulates having a particle size from 50 nm to 300 nm and a glass transition temperature greater than 85° C.;
- 1 wt % to 25 wt % water soluble polymer binder;
- 0.1 wt % to 5 wt % fixing agent;
- and
- 0.1 wt % to 10 wt % slip aid.
A method of preparing a print medium, comprising:
- applying a 0.5 gsm to 10 gsm coating to a substrate, the coating comprising, by solids:
- 20 wt % to 90 wt % of non-film forming polymer particulates having a particle size from 50 nm to 300 nm and a glass transition temperature greater than 85° C.;
- 1 wt % to 25 wt % water soluble polymer binder;
- 0.1 wt % to 5 wt % fixing agent;
- and
- 0.1 wt % to 10 wt % slip aid;
- and
- calendering the coating on the substrate at a temperature from 35° C. to 50° C. and at a pressure from 500 psi to 1500 psi, resulting in the coating having smoothness less than 3 microns, and a surface gloss greater than 60% prior to printing thereon measured at a 75 degree angle.
A printing system, comprising:
- a high speed, inkjet digital press;
- a print medium to load in the high speed, inkjet digital press, said print medium comprising a substrate having a coating applied thereto, the coating comprising, by solids:
- 20 wt % to 90 wt % of non-film forming polymer particulates having a particle size from 50 nm to 300 nm and a glass transition temperature greater than 85° C.;
- 1 wt % to 25 wt % water soluble polymer binder;
- 0.1 wt % to 5 wt % fixing agent;
- and
- 0.1 wt % to 10 wt % slip aid;
- and
- an inkjet ink to load or is pre-loaded in the digital press, wherein the inkjet ink includes a colorant to interact with the fixing agent upon printing the inkjet ink on the print medium.
