We frame to conservation standard as standard and will frame to museum standard if required. This means that that all processes affecting the artwork be fully reversible. In other words, what you have framed to conservation standard can be returned to its former state, i.e. prior to framing, at any time up to 20 years.
We always use white core mount card* which gives a pristine white bevel and stays pristine white, unlike cream core mount card used by most framers, which turns brown with age.
*except for our museum standard board which has a solid colour matching the face colour, and black core. used when requested.
