Until i use photoshop and illustrator CS on osx
i have this problem... when i create a duotone image in photoshop and place it in illustrator. i can't have my 30 degrees between the 2 pantones.
If i change it manually in the illustrator separation setup, and save it to postcript file, the software seem to reset by default my two colors to 45degree... Someone can tell me why and how i can set it like that.
For example :
pms 185 : 45 degree
pms 021 : 15 degree
Now it's like this
pms 185 : 45
pms 021 : 45
Thanks and sorry about my english

Do you have InDesign? I know I have had to reset the angles in ID before to get a Duotone to work. Just a thought that might help.
Good luck!

I might be wrong...don't flame me if I am :D, A duotone as I understand it, is a multichannel image in disguise (Never had a job that specifically required me to create a duotone)...having read the help file in PhotoShop 7 it actually states in there that you can get undesirable results if you export such a file without converting to a multichannel image and exporting as an EPS. (If you convert your duotone to multichannel save it as a DCS or DCS2 file (Desktop Colour Separations - DCS2 keeps all the channels in one file) you might have better control over the screen angles in illustrator because it is no longer a composite channel)
I only have Illustrator 8 on my system however and don't own a postscript printer and so can't really run any tests to check this or even recreate your problem (cannot import a duotone psd file)
I think the reason Illustrator defaults to 45 degrees is because as with black it is the safest angle to use for an image that may only be using one colour be it black or a spot...and due to the nature of a duotone PSD file it might not be able to figure out for itself that there is more than one channel (in Quark 4.1 i found it to default all screen angles to 45 degrees for spot colours)
Please go easy on me if I'm wrong folks :D
Ghastly, how dare you post advice you're not sure of!!!
Just kidding :D
Sounds logical to me although I've never actually used a doutone either. http://home.comcast.net/~rnick9/koolsmiley.gif
