reparing images for the screen is a snap compared to what you have to 
go through to get images ripe for the printing process. If all you ever 
want to do is print your images to a desktop laser or inkjet printer, the task 
is a little easier, but you still must consider some guidelines. And prepping 
your images for offset printing? Well, throw in an additional set of guide-
lines. It’s not rocket science, mind you. If you stick to the basic rules and, 
more importantly, spend some time developing a good working relationship 
with your service bureau and offset printer, you’re good to go.
Getting the Right Resolution, 
Mode, and Format
If you’re not familiar with the concept of resolution, 
I suggest taking a look at Book II, Chapter 1. That’s 
where I cover all the basics on resolution, pixel 
dimension, resampling, and other related topics. 
For full descriptions on color modes and file for-
mats, see Book II, Chapter 2. That said, the following 
sections give you the lowdown on the proper settings 
for an image that will ultimately go to print.
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.)
