Hi Jim,
I have done it in the past by using the Batch Filter to crop the image. When you crop, there is a read-out of the pixel size so you can, with care, produce 4 accurate and separate crops on the same image. As I remember, I did not make 4 images from the batch filter but made crop 1, printed to file, then set crop 2 by dragging the crop rectangle, PTF again .... etc.
It helps to have an even number of pixels in both directions.
I tested the accuracy by placing them on a page in compact layout and PTF again.
