Something I've never understood is how Wilhelm has always managed to give Ultrachrome prints on Epson Enhanced Matte and Watercolour Radiant White better longevity than prints on Epson Velvet Fine Art - which is totally against real-world experience. Enhanced Matte isn't even acid-free and my understanding is that the same goes for Watercolour Radiant White.

Can anyone please cast some light on this?
