  • 1. What is different indigital print ?
  • 2. Digital world – Printing world“Success in the online world will, I think, beget greater success in the printed medium. […] If we are successful, our industry has the potential to reshape itself, and to be healthier than ever before.” R. Murdoch Plate setter pdf Digital printer
  • 3. Digital print – a business perspective Quality of print: Zero compromise “Digital campaigns combined with printed direct-mail see 62% ROI increase”, OMD UK, 2009. Quality of e-readers is still far below printed books.
  • 4. Digital print: a business perspective Close-to-market Web-to- Easy Print proofingCO2 footprint Less stock Less waste Print-on-Demand Less chemicals Sustainable digital print Versioning Personalisation Cheaper short Variable data runs Flexibility, very fast deliveries Shorter production times
  • 5.

  • 8. What is a “good enough quality”?Paper choiceChose the right paper for the right application Functionality: toner or inkjet? Uncoated or coated paper? Paper glossPaper and print gloss effects can be very different between conventional and digital print. Toners are often matt and applied in thick layers on the paper surface.When needed, use varnish, glosser, laminate foils or correct toner gloss on press.
  • 9. What is “good enough” qualityRunnability: define your own metrics • How many jams can your production flow stand? • What kind of quality requires your finishing equipment? Would this staple go through your folding/binding line?
  • 10. What is “good enough quality”?Printability: zero compromise • The right colours Without With colour colour profile profile www.cleverprinting.de Many toner based print seem “too red” but this is often the result of poor colour management. Reproduction of large fulltone areas in laser printing is often difficult. Varnishes or laminates can bring more homogeneity and depth to the print.
  • 11. What is “good enough quality”?Aspect of final product: zero compromise • Product flatness: cause: paper moisture and dimensional stability • Toner cracking at fold or in cut: cause: poor toner adhesion on substrate Toner cracking Good fold
  • 12. ConclusionToday, print is competing with digital mediaDigital printing can fulfil the needs of modern media productionFuture for digital print? If print can: • Add value to the media • Fulfil the needs of modern media production • And fulfil its core business! EXCELLENT reproduction and diffusion of information
