Sub-eloxal printing

Sub-eloxal printing (colour chart)  | © RATHGEBER GmbH & Co. KG


Digital or screen printing which is printed in the open pores of the aluminium's oxide layer. The subsequent sealing of the material traps the ink under the glass-hard oxide layer, making it scratch-resistant.

The benefits for you

  • Digital printing allows variable data and photo-realistic images to be printed too
  • Excellent resistance to mechanical, thermal and chemical stress, as well as UV weathering


  • Anodised aluminium (fully anodised to DIN 30645)

Possible uses

  • For heavy-duty plates indoors and outdoors
