A primer roller may include a cylinder having an outer support surface. The outer support surface support surface may have a length in an axial direction and a fixed outer diameter extending along the length. The roller may further comprise, at least at least one elastically deformable annular sleeve having an axial length less than the axial length of the support surface of the cylinder an external diameter greater than the outer diameter of the support surface of the cylinder, and an internal diameter which provides a friction fit on the support surface of the cylinder. The outer surface of the support roller comprises a plurality of fluid outlets. The outlets are distributed about the support surface. Fluid expelled from the fluid outlets enables the sleeve to be slidably positioned relative to the support surface. A priming apparatus and a print press are also disclosed.

Primer apparatus

Herein is described a method of printing on a textile substrate. The method may comprise: a. applying a primer comprising a cross-linkable primer resin onto a surface of the textile substrate to form a primer layer; b. electrophotographically printing onto the primer layer an electrostatic ink composition comprising a cross-linkable thermoplastic resin to form a printed layer; c. applying a cross-linking composition comprising a cross-linking agent to the printed layer, wherein i. the cross-linking agent penetrates into at least the electrostatic ink composition and the primer layer; and/or ii. the cross-linking agent is a non-isocyanate agent; and d. activating the cross-linking agent. Printed textiles are also described.

Textile printing

Herein is described a method of printing an image on a textile. The method comprises electrophotographically printing an image onto a textile substrate using an electrophotographic ink composition, applying a coating composition comprising a polymer and a crosslinking agent to the printed electrophotographic ink, and crosslinking the applied coating composition.
