ATTENTION
Large format inkjet print longevity
Although OP Output Printing Service is using fade-resistant HP Vivera Inkjet inks in the HP T770, printout fading issues continue to be a problem. After researching this issue, the simple answer to the fading problem is to recommend immediately laminating all printouts that will hang for an extended period of time or use UV plexiglass to protect the printout. Do not expose printouts to direct sunlight.
OP Output does not guarantee longevity of any inkjet output older than one semester.
