Hi Jim,<br>

Fine!<br>

<p>
|
|
<i>> The resolution on xscanimage only goes up to 600dpi though</i><br>
|
|
Yes, thats the scanners optical resolution.<br>
|
|
You can scan with 600 dpi in x and with 1200 dpi in y resolution!<br>
|

Color correction for printers is an ugly thing. The printed picture<br>
|
|
will always look different from the original. What can be done<br>
|
|
relative simple is to use a gamma-correction for the printer.<br>
|
|
<p>
|

|
|
The 9600 dpi is a lie. The driver Takes two pixels and generates some<br>
|
|
addidtional pixels between two scanned pixels.<br>
|
|
9600 dpi could be intersiting if you like to scan with a transparencey adapter<br>
|
|
from a slide or a negative.<br>
|
|
