HD Printing

As standard, all of our envelopes are full colour, litho printed, using HD printing technology. HD printing gives the finest print quality possible with more dots than conventional screening. More dots mean a sharper image.

  • HD printing produces smooth, punchy colours. The ultra tight dot produces images that look almost photographic.
  • No more nasty digital dots, HD printing eliminates the ‘grain’ you often get when printing digitally (or use conventional litho for that matter).
  • Solid areas of colour are consistent and don’t suffer banding.
  • HD printing offers more flexibility in design.
