Service bureaus are great: They keep and maintain all the equipment, know the ins and outs of both your software and your printing press requirements, and turn jobs around quickly ‚ at least most of the time. Working with a service bureau involves commitment and communication between both parties. They need your business; you need their expertise and equipment.

To ensure that you get what you want (fast, accurate service) and that the service bureau gets what it wants (no-hassle clients and printing jobs), make sure that you both understand your standards and needs. Keep in mind that the service bureau has many customers, all of whom do things differently. Service bureaus likewise must not impose unreasonable requirements just for the sake of consistency, because customers can have good reasons for doing things differently.

Paying attention to a few basic issues can help you establish a productive relationship with your service bureau.

Sending documents versus output files

Since you have the Package feature, do you give the service bureau your actual InDesign documents or do you send an EPS, PostScript, or PDF output file?

Cross-Reference ‚  

Chapter 32 shows you how to create output files

The answer depends on several things:

Basically, the question is "Whom do you trust more ‚ yourself or the service bureau?" Only you can answer that question. But in either case, there are two things that you can do to help prevent miscommunication : Provide the report file to the service bureau and also provide a proof copy of your document. The service bureau uses these tools to see if its output matches your expectations ‚ regardless of whether you provided a document file or output file.

Determining output settings

A common area of miscommunication between designers and service bureaus is determining who sets controls over line screens, registration marks, and other output controls. Whoever has the expertise to make the right choices should handle these options. And it should be clear to both parties who is responsible for what aspect of output controls ‚ you don't want to use conflicting settings or accidentally override the desired settings:

In all cases, determine who is responsible for every aspect of output controls to ensure that someone does not specify a setting outside his or her area of responsibility without first checking with the other parties.

Note ‚  

Smart service bureaus do know how to edit an output file to change some settings, such as dpi and line-screen, that are encoded in those files, but don't count on their doing that work for you except in emergencies. And then they should let you know what they did and why. And remember: not all output files can be edited (such as EPS and PostScript files created as binary files), or they can be edited only in a limited way (such as PDF files).

Ensuring correct bleeds

When you create an image that bleeds, it must actually print beyond the crop marks. There must be enough of the bleeding image that if the paper moves slightly in the press, the image still bleeds. (Most printers expect 1 / 8 inch, or about a pica, of trim area for a bleed .) In most cases, the document page is smaller than both the page size (specified in InDesign through the File ‚ Document Setup option) and the paper size, so that the margin between pages is sufficient to allow for a bleed. If your document page is the same size as your paper size, the paper size limits how much of your bleed actually prints: Any part of the bleed that extends beyond the paper size specified is cut off. (This problem derives from the way PostScript controls printing; it has nothing to do with InDesign.)

Note ‚  

This paper-size limit applied even if you set bleed and slug space in the Document Setup dialog box. These tell the printer how much of material outside the page boundaries to output, so they're not cropped out automatically. But the paper, film negatives , or plates they are output to still has to be large enough to physically accommodate them.

Make sure that your service bureau knows that you're using bleeds and whether you specified a special paper or page size because that may be a factor in the way the operator outputs your job.

Sending oversized pages

If you use a paper size larger than U.S. letter size (8.5 by 11 inches), tell the service bureau in advance, because the paper size might affect how the operator sends your job to the imagesetter. Many service bureaus use a utility program that automatically rotates pages to save film, because pages rotated 90 degrees still fit along the width of typesetting paper and film rolls. But if you specify a larger paper size to make room for bleeds or because your document will be printed at tabloid size, this rotation might cause the tops and/or bottoms of your document pages to be cut off.

I've worked with service bureaus that forgot that they loaded this page-rotation utility, so the operator didn't think to unload it for our oversized pages. It took a while to figure out what was going on because my publication's layout staff were certain that we weren't doing the rotation (the service bureau assumed we had), and the service bureau had forgotten that it was using the rotation utility.
