The Artwork
The artwork can consist of just about anything, providing it is two-dimensional: paintings in either acrylic, watercolour, oil or pastel, silk painting, pencil drawings, pen and ink drawings, etchings, screenprints, photographs, digitally created artworks or even textiles and fabrics.
All artwork should be dry and/or fixed properly before scanning.
All artwork needs to be made as flat as possible, so all mounts and frames need to be removed.
All copyright should be checked if you have not produced the artwork - be sure that you may legally reproduce the work.
