Abstract
A process for transfer printing onto solid substrates made of plastics or having a surface layer of varnish or plastic is described. According to the invention described a sheet dye carrier at a temperature suitable for dye transfer is pressed to a preferably preheated surface and/or to a limited area of the surface to be printed by means of superatmospheric gas pressure, in particular by means of a flowing gas. Additionally the surface to be printed is maintained at a temperature below the thermoplastic range during the transfer process.
