Abstract: The present disclosure is drawn to printing systems. In one example, a printing system can include a pretreatment head, an inkjet print head, and a post-treatment head. The pretreatment head can include a first plasma generator to apply a plasma treatment to a media substrate. The inkjet print head can be positioned with respect to the pretreatment head to form a printed image on the media substrate after the plasma treatment. The post-treatment head can include a second plasma generator positioned with respect to the inkjet print head to treat the printed image on the media substrate.

Abstract: The present disclosure is drawn to material sets, methods and printed articles and container supports. In one example, a material set can include a particulate fusible build material having an average particle size ranging from about 0.01 μm to about 200 μm, wherein the particulate fusible build material is a polymer powder, a metal composite powder, or a combination thereof. A fusing ink includes a fusing agent in a first liquid vehicle, wherein the fusing agent fuses the particulate fusible build material when exposed to electromagnetic energy or thermal energy. A binding ink includes a binding agent in a second liquid vehicle, wherein the binding agent temporarily binds the fusible build material when exposed to moderate temperatures ranging from ambient to 150° C.

Abstract: A non-Newtonian photo-curable ink composition that comprises a combination of metal oxide particles in an amount ranging from about 0.1 wt % to about 20 wt % based on the total weight of the ink; an organic solvent; a photo-initiator; and a polymerizable material wherein the ink composition has a first dynamic viscosity ranging from 25 cps to 10,000 cps at a first state and a second dynamic viscosity ranging from 1 cps to 50 cps at a second state. Also described herein is a method for making such non-Newtonian photo-curable ink composition and a method for producing printed images using such non-Newtonian photo-curable ink composition.
