Performing a “zoom test”
Tip
If your keyboard has Page Up, Page Down, Home, and End keys, you can use them to
inspect a magnified Photoshop document. Home goes to the top left corner, and End goes
to the bottom right corner. Add the Ctrl key (Windows) or the Command key (Mac) to
make Page Up/Page Down keys navigate horizontally, and add the Shift key to scroll in
smaller increments.It’s expensive to redo a big print job, so before you send out an image for final output, take a few
minutes to make sure everything is appropriate for your output device and that you haven’t
overlooked any potentially problematic details. Start with the image resolution.
1. Choose Image > Image Size.
2. Verify that the width and height are the final output size and that the resolution is
appropriate. For most printing, 300 ppi produces good results.This image has a width of 11" and a height of 17", which is the final size of the poster. Its
resolution is 300 ppi. The size and resolution are appropriate.
3. Click OK to close the dialog box.
