It's probably the printer, not InDesign, that is shifting things. +/- 1/16" is well within the design tolerance of most laser printers. Devices like this use sensors and rollers to move and align paper, and they simple are not built to the same tight tolerances you find on a printing press. If you print a dozen sets you likely will find some drift between the sets.
True, except that it is the commercial printer that is seeing and having the problem. Sorry if I wasn't clear on that.
Are they using a press?
Well I don't know for a fact that it is, but the customer is a major International Fortune 500 Company and this is an Installation sheet printed and included in one of their product packages, so I would imagine it is an offset press.
Besides, if the commercial printer was using a commercial Laser printer, can't they print 2-sided? There is no problem when it is printed 2-sided, the images align because both margins are offset in the same direction. It is only when it is printed 1-sided (one side to each printing plate) that the problem becomes obvious because the offsets are in the opposite directions. (BTW, it is B&W)
Most commercial laser printers are no more accurate for positioning than your desktop printer. That's the nature of the technology.
Without seeing the file and how the printer is setting up it's really not possible to do more than speculate, but if your margins are mirrored, the prints should align within the limits of the equipment.
Facing pages or non-facing pages?
Are the ID document set up page size and output paper size of different sizes?
If they are, please try the following:
In Print dialog > Set up > select Page position > Centered.
Peter, thanks for your replies.
I'm not sure what you mean by "If your margins are Mirrored"? Is that the same reference as rajsre's question of whether or not the pages are facing or non-facing?
Rajsre, thanks for their reply.
The ID file is Non- facing pages.
I'm pretty sure the setup and the print sizes are the same, 11x17. I have to go into the office this weekend for something else and I will check to make doubly sure.
In the mean time, does anyone have any more speculations on where to look for an errant setting that I can check when I go in?
With non-facing pages, inside/outside margins uniform and page set up matching with output paper size, the next setting to be seen is bleed setting: Please see if any uneven inside/outside bleed settings exist. Please set "page position" to center and see a proof print. This setting is available in "Set Up" tab.
If it is still uneven margin, the Printer specific dialog is to be seen (i.e. the settings you do by clicking "Printer" button in the print dialog.
If you have uneven margins, pages must be mirror-images on odd and even -- wide margin on the left on page, on the right on the next, if you want to print them back to back.
