Default Poly vs metal

Hi

I need some advise on a prepress matter - I've started working with a new company and I'm managing the production of several hundred questionnaires. I'm also working with a new printer.

These questionnaires, once printed, will be sent out to people who will fill them out and send them back. The questionnaires will then be data scanned. The scanning people tell me that even the very slightest movement at the print stage will throw out the scanning setup and they will have to setup all over again if this occurs. Would using polyplates for this job be the best option? Or would it be better to request metal plates due to the sensitivity of the scanning software?
Thanks in advance for any advice

To me poly should work fine. Your people are asking for accurate registration, and the type of plate should not affect that. The quality of the press might, and the quality of the operator will, but the plate should not cause the problem. If the press run is only in the hundreds, then poly should work fine.

I would let the printer know of the need for accurate positioning through the job, just for something to watch for.

I am wondering if some kind of special crop marks would be in order that would show if the job trims badly by leaving a bit of the crop mark on the final sheets.

Actually, there is hundreds of questionnaires but each questionnaire requires a print run of about 12,000 - thus my worry that some of the elements may shift...even minutely. Problem is, the client is not allowing me to talk directly with the printer so it makes this even harder to control! Would the increased print-run make a difference do you think?

I've setup cross hairs 10mm in from the crop marks so that the scanners can align to these instead of working from page borders - I'm hoping this will help them!

12,000 is still in the ballpark for poly plates, I think. It is out of range of the cheaper paper-based plates, however. Too bad about not being able to talk to a printer. They can give you the best advice on whether the plates they use will work on a run of that length.

One place I worked would not use anything but metal, even for very short runs. They felt that reprints (possible on metal, not so much on poly, I guess) made up for the cost difference.

It really depends on how your printer prints them - Polyester does stretch a bit - but I would think guilotining is more the problem
Some printers will print them one at a time on cut size paper - others (more specialist) will print them 8 to view and print the front and backs at the same time - these sheets need guiloting though and u may get some movement . I really dont think it is your job to worry about these issues or give advice - once u do this the printer will try and blame you for the problem.
What I would do is draw up a list of specifications required and send it the printer - he has to do what he has to to get u what u want

Thanks very much for the advice - I will give the client a list of things I feel could be an issue with this kind of job and the printer can take it from there. I'll just hope that the message is conveyed
