[Rick Lang] “Please let me know if these are the ones you use and if I can print right up to the very small hub as I want as large a print-area as possible.”
I don’t think they’re exactly the same, but that doesn’t mean they aren’t fine. The part number for my DVDs is DVD-WPPSK 16-HC, and then the description is “-R White hub inkjet 16x hard coat recording surface MID: TYG03.”
I get them from a very small outfit, Genesys DTP. The owner knows his stock very well and can advise you.
They are printable right to the hub. I really like them – I rarely have an issue with burning them (I suspect, when I do, that it is a software issue). And I can’t recall having had one returned for non-readability.
