Continuing the conversation....
I've been a customer for a while now and tried to chunk up a DVD (again, a while back) but didn't have much success. It's most likely because I didn't have access to a good scanner.
Now that I've recently retired my Canon iP4500 and just bought a Canon MX922 and have also recently switched from JVC Watershield DVDs to FalconMedia SmartGuard Glossy DVDs, I'm back to see if anything has changed with regard to providing a target for DVDs.
With more printers having the capability to print on CD/DVDs, is there any chance you would reconsider your position of not making a round target? It's been a few years now that Canon has been able to provide direct to CD/DVD printers in the US similar to what Epson has been doing for years.
As the MX922 has a scanner and probably better software than what I had before, I'll have to give your suggestion a try: ...print a 4x3 poster of the target from 1x1.87 inch pages and then printing that to file: you'd get 12 files all chunked up for you. Then just print those 4 at a time on the discs and piece them together from the scans.
At any rate, I'm bringing this topic to the top for consideration. Thanks.
