Set the resolution

You can change the resolution and print dimensions of the image by entering a higher or lower value. When you do this and the Resample Image box is checked, Photoshop Elements will either add pixels (sample up) or throw them away (downsample). Another rule of thumb: Never sample your images up. Doing so will result in poor image quality as Photoshop Elements can only estimate what information to add; however, downsampling to make your image smaller is generally fine. Ideally, use an image with the resolution and size closest to what is needed for the final output. To get an idea of what resolutions to use, look at the following examples.

16K file size 72 x 108 pixel dim. 1"x 1.5" print size 72-ppi resolution.

176K file size 200 x 300 pixel dim. 1" x 1.5" print size 200-ppi resolution.

72 ppiFor screen viewing of Web pages or online materials.

120 to 150 ppiFor output to typical desktop laser and inkjet printers.

A 72-ppi image (left) resampled up to 150 ppi (right) results in poor image quality.

A 300-ppi image (left) downsampled to 150 ppi (right) results in adequate image quality.

200 to 250 ppiFor most professional offset presses; used for color magazines and brochures.
