When scanning Greyscale images into AXA, it is not uncommon for the cels not to match the camera window and manual alignment having to be performed, This is due to Dots Per Inch mismatches. The following is one particular method I use to get around this problem, my output is via a DPS perception card (PAL) hence the 5:4 aspect ratio :

1. Decide what DPI you're going to use --- (I use 100 DPI in greyscale mode - B/W photo on HP scanners , it seems to work well enough.).
2. Set your process resolution to 11 * your DPI by 8.5 * your DPI --- (mine is 1100x850).
3. set your output resolution to 720x576.
4. Click on SCANIT and ensure that 'convert to greyscale' is DESELECTED.
5. After doing a few preview scans of one of your drawings , to get your exposure correct , do a preview scan of your Graticule (see note below) and after setting your DPI (mine is 100 DPI) make your scanning area 8.5 inches by 11 inches ( this will be rotated later) and center it on your Grat. This preview scan is mainly to keep your pegs central in the camera window.
6. Your now ready to start scanning your scene, Keep the scanning area the same throughout the scanning session.
7. If you're importing a BG, one you've generated in a 3D program, for example, and it's been rendered at your output resolution size, (mine is 720x576) put it on it's own pegbar and scale it up to match your process resolution, for me that means 152.78% --- ( 1100/720 = 1.5278) don't worry about it becoming BLOCKY, it will be reduced when composited to your final output resolution which is what it came in at anyway!

            card. If you Email me I can arrange to send you a copy of one I drew up …

            If you are a PAL Perception user, you'll need to resize the field chart in the AXA program directory to 720x576 for
            it to make any sense within AXA, you can use any paint package to do so .
