Final answer:
It is false to encourage dry mounting for original artwork because it is an irreversible process that can devalue and damage the artwork. Conservation methods which are reversible are preferred for preserving the original state and value of the artwork.
Step-by-step explanation:
It is generally considered to be false that you should encourage customers to drymount original artwork. Dry mounting is a process where artwork is permanently adhered to a rigid backing board. While this prevents the art from wrinkling or buckling, it is not considered reversible, and this lack of reversibility can greatly diminish the value and preservation quality of the artwork. Museums and professional art conservators typically prefer using conservation methods that are reversible, to ensure that the art can be preserved in its original state as much as possible. Therefore, it is best practice to recommend archival methods of mounting that do not permanently alter the artwork.
