Indigo Color Printing


Indigo was first coined in 1977 after the company that was formed by Benny Landa. He aimed at developing photocopiers. But as the ElectroInk technology was introduced, Landa resorted to an offset press that created a digital type that is plateless, known as the E-Print 1000.

ElectroInk inspired the current trend now when it comes to Indigo color printing. The process involves small color particles hovering on Isopar or Imaging Oil. Such particles can be drawn or pulled away through voltage differential. Such process makes Indigo printing to have results that can be comparable with the quality of offset lithography.
