From what I've experienced, the Ultrachromes are flat-out not as durable as
the pigmented set (9500/10000cf). The inks can color shift (like inks are
melting) when laminating with a high heat laminate, remember that 250 degrees
is REALLY hot, chemically the inks just are not taking it. The 10000 pigments
do fine however, but who knows what this is really doing to the media and ink
as far as outright longevity. Epson and 3M are going to have a vinyl and
laminate combo that has an outdoor warranty (like Encad) for around 2 years,
this will only apply to the piggies which is why they still make the 10600
with the archival pigments. Epson flat out states that the Ultrachromes need
to be kept from sun exposure and are completely unsuitable for outdoor
signage, laminated or not. This should tell you something about the durability
of the inkset. Cold laminates are easy to use, and there are inexpensive roll
mounting presses which work just fine if the heat is a worrisome issue.
My experience with the canvases are strange, one of the best coatings I've
found is the Krylon Kamar Varnish. It works extremely well. Some coatings I've
tried have made the ink crack like a giant puzzle within hours. As you know it
is imperative to coat the canvases one way or another, otherwise the inks rub
off with your fingers ( almost like re-usable canvas!). The prints also look
much better sprayed, with better contrast and greater depth to the image. I'm
still testing some canvases and looking for the best combination.
