Advanced Scanning
Note:
Your Perfection 600
scanner software
supports up to 2400 dpi
scanning resolution,
although you probably
won't need resolution
that high.
For Professional Output
For commercial printer output, multiply the lines per
inch (lpi) that the press prints (your printer can provide
you with this information) by 2 to determine your
scanning resolution.
For example, if the lpi is 150, try scanning at 300 dpi.
(If the resulting file size is too large, multiply the lpi by
1.5 x instead of 2 and try again.)
How To Change Image Resolution
To change the image resolution, move the resolution
slider to the left to decrease resolution or right to
increase resolution.
The dpi display shifts as you do so.
