Graphics
Desktop printing Desktop printing usually requires images within the range of 72 ppi (for photographs printed on
a 300 ppi printer) to 150 ppi (for photographs printed on devices up to 1000 ppi). For line art (1-bit images), make sure
that the resolution of your graphics matches the resolution of the printer.
Web publishing Because online publishing generally requires images with pixel dimensions that fit the intended
monitor, the images are usually less than 500 pixels wide and 400 pixels tall, to leave room for browser window controls
or such layout elements as captions. Creating an original image at screen resolution—96
ppi for Windows–based
images, and 72 ppi for Mac OS–based images—lets you see the image as it will likely appear when viewed from a typical
web browser. When you’re publishing online, the only times you’re likely to need resolutions above those ranges are
when you want viewers to be able to zoom in for more detail in a PDF document, or when you’re producing a
document for printing on demand.
Importing files from other applications
Importing Adobe Illustrator graphics
How you import Illustrator graphics depends on how much editing the graphics require after you import them. You
can import Illustrator graphics into InDesign in their native (.ai) format.
If you want to adjust layer visibility in InDesign...
Import the graphic using the Place command, and when you want to edit it, choose Edit > Edit Original to open the
graphic in Illustrator. For example, for a multilanguage publication, you can create a single illustration that includes
one text layer for each language. You can transform the illustration as a single object in InDesign but you cannot edit
the paths, objects, or text within the illustration.
Layered file with Spanish and English layers
If you want to edit objects and paths in InDesign...
Copy the art from Illustrator and paste it into your InDesign document. For example, in a magazine, you might use
the same design element in each issue, but change its color every month. By pasting a graphic into InDesign, you can
change objects’ color, path, and transparency using the InDesign tools designed for that purpose.
Importing Illustrator graphics with multiple artboards
Illustrator CS4 graphics can include multiple artboards. When you import an Illustrator graphic with multiple
artboards, you can use Import Options to specify which artboard, or “page,” will be imported.
