This paper has the exact same make-up as the original is painted on - 100% α-cellulose. Acid- and lignin-free. There is a visible structure to the paper which gives a textured look and feel close to the original.

It is certified ISO 9706. Which means it conforms to museum quality for the highest age resistance.

I scan the original (not photograph) so it is as accurate as can be. Including all the oily lumps and strokes of the originals. And then If it’s needed I colour-correct on a colour-accurate studio monitor with the original in front of me.
