Digital Printing technology and new alternatives in label printing Mike Englander Durst Phototechnik AG

The Industrial Inkjet Specialist Durst Tau 330 High Speed UV Inkjet Label Press Digital UV Inkjet - Narrow Web Application

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

Needs of the label converter from digital Quality - comparable to conventional Speed - comparable to conventional Material flexibility - comparable to conventional Cost – as long a digital run as possible versus conventional total print cost

Ink Jet For high quality print, you need a combined system incorporating the best of: – Print Head – Ink – Substrate – Web transport – software

Ink Jet - Head Ink Jet Print Heads must be: - scalable for high speeds, - scalable print width, - jet a high opacity white ink - jet new (additional) fluids

Ink Jet - Ink Must have characteristics such as: - Ink properties to work with surface tension of most substrates -Cover a wide color gamut to match high % of Pantone range -Print high opacity white -Have high chemical & scratch resistance -Have high degree of light fastness

Ink Jet - Software Must have characteristics such as: -Highly accurate press linearization -Ink limiting function to reduce costs -Accurate substrate profiling -High speed ripping & dithering -Accurate color management
