Tips: Getting the Resolution Right for Print |
|
Most of the
images that we offer in the library have a dots-per-inch (dpi) ratio
of 72. If you download the for-print image (the larger of the two)
and you'd like to use it in a print document, you'll need to change
the dpi of the image. This can be done in most image editors like
Photoshop, Fireworks, Microsoft Photo Editor, or ImageReady. If
you increase the dpi to 144 dpi (good quality) or 288 dpi (best
quality), make sure to decrease the size of the image by the same
ratio in order to maintain the quality of the image. For example,
a 6x6 inch photograph with a dpi of 72, would need to be resized
to 3x3 inches as it's dpi is increased to 144 dpi. Likewise, if
it's dpi were changed to 288, it would need to be resized to 2x2
inches.   Print
Photos Blurry?The photos below represent print quality. The 288 dpi photo prints crisp and the 72 dpi has to stretch itself and prints with a noticeable grain. To avoid this problem, change the 72 dpi to 144 dpi (good quality) or 288 dpi (best quality) as described in the instructions above.   |
