How to use the ScanSnap SV600 book correction tool

The book correction tool that comes bundled with every ScanSnap SV600 is pretty incredible. It can flatten the curvature of a scanned book page to make it appear as if it was scanned through a regular paper feeder. It can use some of its ScanSnap magic and remove your fingertips from an image if you were required to hold the pages down during a scan. And, it will even let you decide if you want your finished document to appear one or two side-by-side pages at a time as you scroll through – like a book – depending on your personal preference.

While all of that is wonderful, all that list does is focus on the scanner’s capabilities and features, not how to use them to achieve the best possible results. One of the coolest features at your disposal with a ScanSnap SV600 is the image flattening. Bound materials, particularly books, inevitably result in pages bowing near the middle of the book when open, sometimes quite a bit. There are a variety of ways to help the process produce a better, flatter image (i.e. holding down pages to increase flatness) but how do you best manipulate the ScanSnap SV600 book correction tool to produce the flattest, crispest, straightest image possible? 

In the image above you can see the red dotted line of the book correction tool. This is what you will use to snip and clip parts of the image you either can do away with or need to remove to help it look more like a scan than a picture. The difficulty comes when you try to manipulate the size and location of the box. This occurs most often when you start your manual correction effort in any of the four corners. Don’t do that. What we found is if you start on the outside and finish by adjusting the sliders along the binding in the middle you will end up having to realign the corners slider you already spent time adjusting because moving the middle affects the rest.

The best explanation is that the curvature of scanned pages starts in the middle at the binding. If you move the middle sliders second it affects the top and bottom cropping lines that start in the middle and move away from the binding. You’re effectively making it recalibrate how it is reading the image which dictates how it will flatten it. Starting in the middle (and finishing on the outside) sets an “anchor” of sorts for the rest of your correction and is the most efficient way to move through your images during book correction editing.
