Re: Going Web
I am speaking of how many simultaneous rolls are being fed at the same time. In my case we feed up to 3 at once. That is 3, 16pg, 8.5x11 sigs. We usually run 35in. rolls and have a 22.75 in cutoff. This will put pgs 1-2 on outside sig1, 3-4 on inside sig1 and 5-6 on inside sig2. It sounds like you are running a single web, which for the most part is like a sheetfed as far as impo goes, except for the shrinkage factor. Offset will shrink more than coated, at least in my experience. In my case, with the older web, they require center marks extending off the sheet edges in all 4 directions for plate alignment and bending, I would assume a newer press will not require things like this, but will probably require reg. marks in other places to check for things like web growth and fine tune registration, also will probably need compensator marks. In my case I use 3/16" square box in center of sheet so the press will pick this mark up with a sensor and front to back reg. will be held. In the case of a job that has large solid tabs, I will put the comp. marks on the left and right of the sheet so the press will not try to follow the tabs and cause the press guys trouble with backup.
Some of these tips might not apply in your situation, so sorry for the extra parts. If it is a gapless design, meaning no grip area, I am not familiar with the requirements, could be similar.
Good luck in your new experience, I am sure you will do just fine.
