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
