The registration marks are only used to visually match things from one spot to the other. They don't actually affect any operation. I will use it to click on the title on the left side, then use it to align the box in the same spot on the right side.
There isn't any way to get rid of the registration marks, and keep the crop marks. But to get rid of all the marks press [esc].
As far as handling a page moving slightly from page to page.. you are entering the area where Scan Tailor becomes the better tool. To do it in BSW there's two options. One is to do crops for pages in groups. For example, if a crop works for the first 200 pages, you can do:
Code: Select all
Pages = left 1-200
Crop = 941,604, 1888,1557
Pages = left 201-400
Crop = 921,604, 1868,1557
Or you can use the command
InterpolateCrop, which will gradually change the crop window from one spot to another.
Right now the most efficient way to handle changing crops is to uncheck the "crops" checkbox. That will show the crop lines instead of performing the crop. Then you can go forward through the book adjusting the crops. Then go back and edit the configuration so they apply to page ranges.
Perspective changes are handled the same way.
When I scan, I provide a bit extra space around the edges. Also, I normally convert it to pdf's using FineReader, which will handle a bit of rotation if the page slightly moves.
I do have some vague ideas of some enhancements for the future to allow you to grab corners and adjust things throughout the book.
