Grain/Image Size
The size of an original scanned image is also important to the clarity of the
output image. If an image is enlarged too much, the grain of the image may
become obvious, detracting from the image quality. In digital photographs, the
grain introduced by scanning limits how large an image can be successfully
enlarged.
The guidelines below show the maximum recommended enlargement for a few
standard sizes.
Getting the Color You Expect
Our eyes are sensitive enough to perceive thousands of different colors in the
spectrum of visual light, including many colors that cannot be displayed on a
color monitor. The color range, or color gamut, that can be printed with dry ink/
toner is even more limited.
Understanding the color gamut is especially important when you compare how
different technologies and output devices use light to reflect color images with
what we see on a printed page. As colors move from the scanner to the screen to
the press, they are converted from one color model to another so you do not get
in print exactly the same colors you see on the screen.
For this reason, when you are designing for printed output, you always need to
think about what can be reproduced with dry ink/toner on paper and not what
you see on your monitor.
