Not with InkThrift PRO. The GO does have some UV absorption in it. But InkThrift PRO is NOT designed to withstand the amount of LUX you just blasted it with. It is a short term graphics ink.
InkThirft DB could spend months outside.
InkThrift CL could spend somewhere between the two!
But - under no circumstance use InkThrift PRO if your real intention is to provide fade resistance. It’s cheap and printer friendly - but no amount of over-coating is going to put it into the classification of ink (pigment) so that it can withstand direct sunlight!
The ink can only absorb so much LUX. Direct Sunlight one hour can be 100,000. Just outdoor light (not direct) can be in the 15000 - 25000+
Indoor lighting expecting 250lux
Three hours direct for three days is 1200 times the amount of the sample being indoors. But the additional light from outdoors would be considerable as well. It just is not designed for being out doors. Indoors - short term - and even then 1200 lux would shorten the life to be 10% of 120 lux display…
LUX is accumulative based upon intensity!
We are selling a lot of the CL into large format printing where they are using special RIPs to turn off the LK, LLK.
Some are using the DB in a double CMYK somehow…
The RIPs may be European in origin. But they are getting outstanding fade resistance coupled with lower costs.
