Artwork Attaching
There are a number of different ways to attach your artwork to your mount, most of which are done using the Ph7-70 range which ensures the tape is Acid free. Why is Acid free tape important? It ensures that the tape won’t discolour which can transfer to the artwork causing damage. This chemical process is called Cross-Linking and it is caused when two types of polymers in the tape begin to interact with each other overtime.
