I work in prepress AND with Ed the Finisher. We always solicit his advice when we get a job that could be problematic so that we can set the job up correctly to make his job easier. I think that's the mantra in our shop for the most part. We want the job set up correctly from the beginning of the job to the end of the job because alot of work we do is reprints and if someone has to "fix" a job in their department, what's to say that if it comes back as a reprint that the person who "fixed" the job is going to remember a year later what they did exactly to make the job work, or, if the same person is even still working here. We try not to send jobs through that are going to need to be adjusted for on the press or tweaked at the cutter or folder to avoid the hassles and waste. When we get a trifold job, we make sure the panels are set up correctly. If not, we contact the customer, ask them if they want to fix it or if they want us to do it. If we fix it, we try to make sure the customer gets our final working file in case they want to make changes to it in the future so that next time it comes in, the panels will be correct. In the long run, it only makes sense.
