well I ended up setting up a very simple psd after reading this thread and these two support pages from epson, and it worked very well.
it’s not fancy, I used the ‘Print Confirmation Pattern’ image from the first link (resized and cleaned up) as a ghost layer to be turned off or deleted before export as rgb jpeg for print cd per LowrySam’s advice.
I used the taiyo yuden watershield discs, some new surface that’s supposed to prevent smears. it definitely cut drying time down. I used the cd/dvd setting in the print cd print dialog, not the cd/dvd premium surface setting, they were dry in a few hours and have a semi-gloss-looking finish. I’m very happy with the results. I bought them from rima and though they cost twice as much as normal white inkjet dvd-r stock they are worth the extra 30 cents per disc. if anyone knows of a better deal on these I’m interested.
Robert, it seems to me the ‘EasyPrint Module’ that print cd requires to be installed actually has the cd tray driver bundled inside it and cannot be accessed through any other program. if I were you I would give up trying to print with ps and trying to resize in print cd. You can download the template I used here for the time being, with the caution that it’s nothing special and probably inferior to LowrySam’s template, but we don’t have a link to it yet, so I’ll post what I used since it worked for me. I would do the resizing in ps and just keep exporting jpegs and importing them into Print CD using insert->background->select background until you get it right.
