Framing an oil painting on paper involves a process similar to framing other paintings on paper, such as watercolours or acrylics.
According to the reference, framing an oil painting on paper is similar to framing a watercolour or acrylic painting on paper, with a mount, behind glass.
Here are the key elements and considerations when framing an oil painting on paper:
- Use a Mount: A mount (or mat) is typically used around the painting. This not only adds visual appeal but also creates a crucial space between the surface of the painting and the glass. This separation prevents the oil paint from touching the glass, which could cause damage over time.
- Frame Behind Glass: It is best to frame it behind glass. Glass provides protection against dust, dirt, moisture, and UV light (if conservation glass is used), all of which can degrade paper and paint.
- Utilize a Rigid Backing Board: Because a painting on paper is flexible it is important to frame it on a rigid surface like a backing board. This backing board provides stability and support to the paper, preventing it from buckling or warping within the frame.
- Glass is Recommended Even if Varnished: Even if the oil painting on paper has been varnished for protection, the reference states that it is best to frame it behind glass. The added layer of glass offers superior protection against environmental factors and physical damage compared to varnish alone on a flexible surface like paper.
In essence, treating an oil painting on paper like other valuable paper-based artwork by using a mount, backing board, and protective glass is the recommended method for preservation and display.
