Re: Scan Tailor Advanced input format

I think in general people worry far too much about possible quality loss when resaving a few times to JPEG format, and it should certainly not be an issue when book scanning. I did some tests once, and even after resaving an image with fine detail not best suited to the format many times, it was nec...

Re: I built "Auto page flip Scanner"

I still couldn't make out from the video's or the diagram how the photo interrupter (apparently located below the book cradle) could sense something because as i understand it has a small gap between the IR LED and the photo transistor as seen in the below picture of a photo interrupter. The photo ...

Re: I built "Auto page flip Scanner"

Thanks cday for providing some options. I will investigate these. Since the gutter position varies, some sort of pressure sensors might be a good option. But I was thinking on where to place it? do you have any suggestions? You are right, I think, that using either of the types of sensor identified...

Re: I built "Auto page flip Scanner"

Does anyone know how the platen box is programmed to stop at exactly the book gutter? Presumably the vertical position of the book gutter will vary depending on the thickness of the book, and probably how far through the book has been reached? A mechanical microswitch might be one easy, readily ava...

Re: Single camera - "wrong" side pages flip back

I was also thinking that a spacer could assist in keeping any hold-down device you use out of the wanted view area. Probably obvious... :D I think maybe we're using the term "spacer" and it's use differently. Can you be more specific about how you envision this would work and what you mig...

Re: Single camera - "wrong" side pages flip back

Would placing a spacer of some kind possibly help with keeping the page not being scanned out of the wanted view area? I tried a spacer of various sizes, didn't help much (did a complete "test" scan of the small book used to illustrate the problem, maybe 1/8th of the pages were remotely u...

Do you mean that you can't force the pages flat against the other side of the cradle?

Re: Native font translation - Not Minion Pro/Times New Roman

I don't use Scan Tailor but I do have a copy of Adobe Acrobat although not a recent one. I'm not sure what you mean about combining or editing pages, could you explain in a bit more detail? Also, what form of output from ST are you using, in terms of file format and any other parameters that could b...
