Sustainability of Liquids with
Inkjet Technology
Daniel J. Fry
February 25, 2008
Definition of Sustainability
• According to Webster
– of, relating to, or being a method of harvesting or using a resource so
that the resource is not depleted or permanently damaged
• According to Wikipedia
– is a characteristic of a process or state that can be maintained at a
certain level indefinitely.
Concerns of the Trade Shop
• Film image setters are becoming harder to find and more difficult
to maintain and repair
• Silver film is getting expensive, the longer term viability is
unknown
• Lost margins from converting liquid plate production to digital
sheet production
Options Available to the Trade Shop
• Remain on Silver Films
– Acquire backup processor or processor parts
– Secure long term supply agreements with the film suppliers
• Go Digital
– High cost of entry
– Higher raw material costs
• Identify alternative options for film supply
Silver Film Alternatives
