Tried to use Colorport like somebody sugested in my another thread...
I think that was suggested in this thread too :-]
But I get this error see attached image (Selected paper size too small).
Ahh, well it helps to know what you're doing. You're trying to make a target for a DVD writing printer! Yes, well you shouldn't have to reinvent the wheel as plenty of us have done this before. Of course, you could use a remote profiling service that already has a customized target ready to go.
If you're determined to make your own target, start with an appropriate patch set. If it's an RGB printer driver and you're using i1Profiler for the final profile you could use i1P's minimal 400 patch RGB set. i1P's engine makes remarkably good profiles from smaller patch sets like this. Of course you can use a larger patch set if you're in for the extra work.
When I've made targets for DVD writers I use CP to make a rectangular target in CP for an i1Pro (not the iO) - the size isn't important but let's just say a 5x7 page size will work well for 400 patches. And then
reposition the patches manually in Photoshop to fit the shape of the disc including the hole in the middle. While doing this feel free to shrink the size of the patches to fit more on each disc. Be sure to include the row numbering when repositioning to the patches so you can keep track of what patch you're on when measuring. You'll likely wind up with a 2+ page (disc) target - no big deal, and you'll need to measure the final prints manually in CP with the i1Pro - not the iO. Since you're measuring the patches one at a time, CP doesn't care if they've been repositioned on the page to fit the disc's shape.
I've been profiling disc writers since they came out about a decade ago - it works fantastically well. Good luck! Hope this helps.
