Letterjazz is Proof Of Work Printing
In a world where printing is ubiquitous and cheap, people don't appreciate paper products any more. Written documents are no longer the proof of work they used to be.
Reading and writing used to be a skill. Documents had to be copied by hand, which made them extremely valuable. The advent of the printing press changed that in a way. Then came the computer and the printer. With the right software and a bit of effort, everyone can produce professional looking documents, virtually indistinguishable from professional printouts.
How can you produce something that looks expensive because it requires labor? The folks at letterjazz.com produce gravure printing with real old machines that literally make a dent into your paper.
