Getting the Right Resolution, Mode, and Format
Resolution and modes
Table 1-1 provides some guidelines about what resolution settings to use
for the most common types of output. Remember, these are just guidelines.
They aren’t chiseled in stone to withstand the sands of time or anything lofty
like that. You need to communicate with your service bureau, offset printer,
or client and get specifications and/or recommendations. (See the section
“Working with a Service Bureau,” later in this chapter.)
