Digital BW, The Print

Keith/Julian,

Thanks for the response. I think I've got it now...the CCDs are spaced
1/3200 of an inch horizontally while the stepper motor moves the array
1/1600 inch vertically with each "step". I have always avoided any setting >
1600ppi on my 1680, but now I won't hesitate to use 3200 if the situation
demands it.
