Resolution guidelines
This table shows the recommended resolutions in dots per inch
or pixels per inch for the image types and printing methods just
described. Also, you may want to experiment with your
scanner settings, possibly using a cropped version of your
image to save time, until you achieve the desired results.
Resolution guidelines
Tip: Here’s how to calculate more precisely the required resolution
for gray scale or color on an electronic color printer or a
printing press:
1. Find out the lines per inch of the printing method. This is
the measurement of resolution for high quality image
printing. Do not confuse it with dots per inch, which is not
an equivalent measurement.
2. Multiply the lines per inch by two to find the best scanning
resolution. For example, for 133 lines per inch (a common
resolution for magazines and books), scan your image at
266 dpi (2 x 133 = 266).
Tip: For even smaller file sizes, try scanning at about 1.5 times the
lines per inch. This may cause little or no perceptible loss of
output quality.
