Backing sheet is a thin or thick paperboard, which is normally used as a buffer between the artwork/photo and the backing board of the picture frame.
But these sheets are versatile:
You'll find the most suitable type below. They are both in standard sizes and custom sizes:
Nice allround backing sheets, which are especially suitable for photo mounting and for framing where a part of the backing sheet will be visible (around the edges of the artwork or an artwork, which is partly translucent.
For instance an artwork with dark colors can be given a boost in the darkest colors by using a black backing sheet behind it.
When you are looking for museum grade framing for fragile or sensitive content such as unsealed watercolor paintings, these backing sheets are the way to go.
They are all museum-graded in terms of no acidic or alkaline compounds present and completely stable in color.
We recommend, that a good quality PH neutral tape, such as Filmoplast P tape, is used with these backing sheets.
