We are looking at getting a flatbed, and stratojet says their prints are rated for 2 years not laminated. Is that average? Our HP latex can take full sun for 3 years or more.
For most UV Printing its similar between 2-3 years without lamination. But the average depends on the outdoor conditions, material quality and weather. I am surprised to hear latex can do 3 years. I think its similar too, as they also recommend getting lamination done if you would be keeping out for a longer period. I am using the Stratojet Shark printer for a while now (about 4 years), not had any issues in regards to outdoor durability for yard signs.
But even if the rating say 2 years or 3 years, on regular conditions you would notice prints lasting for even 4 years with having a huge quality difference, as most companies they rate the fading from the point colors starts to fade more than 4%, but to us fading point is much more than that.
From my experience moving to UV from Latex, I have felt UV has more durability than latex for rigid surfaces. With Latex had alot of restrictions on substrates.
