Determine a suggested resolution for an image

If you plan to print your image using a halftone screen, the range of suitable image resolutions depends on the screen

frequency of your output device. Photoshop can determine a recommended image resolution based on the screen

frequency of your output device.

Note: If your image resolution is more than 2.5 times the screen ruling, an alert message appears when you try to print

the image. This means that the

image resolution is higher than necessary for the printer. Save a copy of the file, and then

reduce the resolution.

Note that the screen value is used only to calculate the image resolution, not to set the screen for printing.

6 For Quality, select an option:

Draft Produces a resolution that is the same as the screen frequency (no lower than 72 pixels per inch).

Good Produces a resolution 1.5 times the screen frequency.

Best Produces a resolution 2 times the screen frequency.
