Thanks for the help guys! One more question. My friend says on their HP LFP within a week of outdoors the ink fades real fast on the tyvek print. If I use my Canon with the archival ink will this mean it won't fade?
Assuming 100,000 lux for 12 hours per day (an extreme sunlight condition) such as in a bright sunny 'near the equator" outdoor environment for one week, and this light level accumulates to 8.4 Megalux hours of total exposure. This dose may be enough to burn out some optical brighteners if they are incorporated in the media, but not nearly enough to otherwise cause noticeable fade in the major OEM aqueous ink sets (e.g., Epson K3VM, HP Vivera pigment, Canon Lucia EX). Give it 10-12 weeks and then you might start to see some subtle shifts in color and tone, but indoor light levels will take many years to accumulate similar levels of exposure. If your friend really saw easily noticeable fade in a week on this substrate, chances are the inkjet printer in question used dyes rather than high quality pigments or there is an extreme level of incompatibility with this media with the chosen ink set. I've never documented in any of my light fade studies yet this level of ink/media incompatibility, but one should never say never.
cheers,
Mark
