Abstract: In an example of the disclosure, a blanket servicing system includes a rotatably mounted endless cleaning surface and a scraper. The endless cleaning surface is to have a first engagement with a blanket to obtain a layer of thermoplastic print agent from the blanket. The endless cleaning surface is to have a second engagement with the blanket to receive residue from the blanket onto the layer of thermoplastic print agent. The scraper is to scrape the endless cleaning surface to transfer the residue from the endless cleaning surface to a collection element.

Abstract: In an example, a print apparatus comprises an intermediate transfer member to receive thermoplastic print agent from a photoconductive surface, a rotatably mounted endless cleaning surface to receive a layer of thermoplastic print agent from the intermediate transfer member and a heater, to heat the endless cleaning surface. The endless cleaning surface may be to engage with the intermediate transfer member when heated to transfer residue from the intermediate transfer member to the layer of thermoplastic print agent on the endless cleaning surface.

Abstract: The present disclosure relates to a method of producing an intermediate transfer blanket. The method includes spray-coating a blanket body with a release layer composition including a curable polysiloxane polymer and solid particles of an electrically conductive material. The blanket body is subjected to motion during spray-coating, such that the release layer composition is subjected to shear forces as it deposits on the blanket body.

Abstract: An intermediate transfer member for digital offset printing, comprising a cured silicone release layer formed by curing a curable silicone release formulation comprising a polyalkylsiloxane containing at least two vinyl groups; an at least partially fluorinated polyalkylsiloxane containing at least two vinyl groups; a polyalkylsiloxane cross-linker containing at least two Si-H bonds; and a catalyst or photoinitiator; wherein fluorine atoms provide at least 2.5 wt.% of the total weight of polyalkylsiloxane compounds. There is also described a method of producing an intermediate transfer member, and a curable silicone release formulation for an intermediate transfer member.
