3. My artwork or print is yellowing, what is causing this?

Share this article:

This is caused by one of two things:

Harmful UV rays. Exposure to sunlight causes a relatively uniform yellowing and discolouration of paper. This can be avoided by using a UV protective glass. Our range of glass blocks up to 99% of damaging UV rays.

Acidity. Acidity causes yellowing and discolouration on paper and fabrics. It is characterised by more irregular spotting or yellowing from certain edges inwards – these are most likely high-contact points where the paper is closest or directly joined to acidic, non-archival elements. We stock a range of acid free boards that are used in our archival framing processes to address this issue and give you a longer lasting product.
