The main alternatives

• Electro-Ink from HP Indigo
• Thin film lamination process bonded to the
  substrate in one shot
• Powder toner xerography from Xeikon
• Toner particles are melted by heat and fused to
  the substrate
• Ink jet from a selection of companies including
  Durst
• creates a digital image by propelling droplets of
  ink onto the substrate
