Apparently not - I've tried it. >(And, indeed, it will make better decisions than you can earlier in the chain, >cos it will know more about the output device). Actually, for all the book's I've sent to press, I've known more or less nothing about the output device(S) - I just get a pre-press spec from the printers, which often takes the form of a Distiller jobspec file. However, I do know a range of things that must not be in the pre-press file, such as hairlines.

Well I'm not going to argue with you, but I have a pre-press spec to work to, and it disallowed C, M and Y channel data. -- Steve _______________________________________________ You are currently subscribed to framers as arch...@mail-archive.com.
