A fair point, thanks Iain. I was looking at an Epson kit from inkexperts.co.uk - I'll see if they can provide a sample.

<t>Hi there. I am considering purchasing a dye sub printer with the intention of printing onto flat-topped PBT plastic keycaps. I have a heat press already, but was wondering if there is a service online (or a kind soul on here) I could use to order a test print before investing in a printer. Thanks ...
