Abstract: The present disclosure is drawn to coated print media, methods of making coated print media, and methods of printing. In one example, a coated print medium can include a substrate, a base coating layer on the substrate, and a top coating layer on the base coating layer. The base coating layer can include an inorganic pigment, a binder, and a fixing agent. The top coating layer can include polyvinyl alcohol and polymer nanobeads having a gloss transition temperature from 70° C. to 350° C. The polyvinyl alcohol and polymer nanobeads can be included at from 50 wt % to 100 wt % by dry weight of the top coating layer.

Abstract: The present disclosure is drawn to methods of embossing print media, printing systems, and printers. In one example, a method of embossing a print medium can include printing a radiation absorbing ink on a coated print medium to form a printed area. The coated print medium can include a print substrate and an expanding coating layer on the print substrate. The expanding coating layer can include a thermal expansion agent having a minimum expansion temperature. The method can further include heating the coated print medium using a heater such that the printed area and unprinted area reach a first temperature from 5 C to 90 C below the minimum expansion temperature. The coated print medium can be irradiated with radiation having a wavelength from 200 nm to 400 nm to selectively heat the print area and expand the thermal expansion agent in the printed area.

Abstract: The present disclosure is drawn to coating compositions that can include an inorganic pigment, a non-ionic surfactant, latex particles, a polyvinyl alcohol, and a cationic fixing agent. The inorganic pigment can be included in an amount from 60 wt % to 90 wt % by dry weight. The latex particles can include a styrene-butadiene copolymer, and can be present in an amount of 4 wt % to less than 10 wt % by dry weight. The polyvinyl alcohol can have a weight average molecular weight of 150,000 Mw to 400,000 Mw.

Abstract: The present disclosure is drawn to methods of embossing print media, printing systems, and printers. In one example, a method of embossing a print medium can include printing an enhancing fluid on a coated print medium to form a printed area. The enhancing fluid can include a colorless radiation absorbing agent capable of converting radiation having a wavelength from 200 nm to 400 nm to heat. A colored ink can also be printed on the print medium to form a visible image. The print medium can include a print substrate and an expanding coating layer on the print substrate. The expanding coating layer can include a thermal expansion agent having a minimum expansion temperature. The coated print medium can be irradiated with radiation having a wavelength from 200 nm to 400 nm to selectively heat the printed area and expand the thermal expansion agent in the printed area.

Abstract: An example of a printable recording medium includes a base substrate, a first ink-receiving layer, and a second ink-receiving layer. The first ink-receiving layer includes a first inorganic pigment in an amount equal to or greater than 70 wt % and a first ink-fixing agent in an amount ranging from about 3 wt % to about 10 wt % based on a total wt % of the first ink-receiving layer. The second ink-receiving layer includes a second inorganic pigment. Both the first ink-receiving layer and the second ink-receiving layer exclude precipitated calcium carbonate.
