I would like to add a spot varnish to a giclee print. To be clear: I don't want to varnish the whole page, but add a designed layer of shapes which are varnished on top of the the giclee. This is for a series of short runs (~10 per run), so I need to keep the costs down.
I have spoken to a large number of printers here in the UK who have all said that this isn't something they do. Beyond this, none have been helpful as to why they can't do it or where someone might do it.
Does anyone have any experience doing this? Is it possible. If not why not?
