scanning manuals

From: Glenn Holmer on 12 Apr 2008 20:45 Looking for suggestions on settings when scanning manuals. I just got a new scanner (HP ScanJet G3010), and I'm using SANE under Linux (Hardy Heron). The first manual I picked shows quite a bit of bleed-through from the opposite page. I put a sheet of white paper between the pages, but it didn't make a difference. How do people get such beautiful scans? Maybe somebody can point me to a good tutorial? -- Glenn Holmer (Q-Link: ShadowM) http://www.lyonlabs.org/commodore/c64.html

If you plan on doing OCR look at tesseract http://code.google.com/p/tesseract-ocr/ which is a command line tool, and if you want to make tesseract less painful, get ocube, http://www.geocities.com/thierryguy/ocube.html which will do a lot of the file conversion tesseract requires automatically.

"the beautiful" scans, you might be talking about for C= stuff, were made on some early scanner's ( i.e. Resolution" was not near what it is now.... hence --- the minamal bleed thru THEN -- was "rejected" by the software ---but as the Rags age--bleed thru is the norm -- And to top it off, in this day and age of Hi-res scanners, -- , the turd pile of an ant, will be reproduced in all it's glory, with modern day scanner's. Not knowing what you are trying to scan ( a magazine or a BOOK ) --- try this instead. Put a piece of BLACK paper behind the page you are trying to scan... thereby (hopefully) killing some of the "virtual reflection" The scans maybe a little dark (slightly grayish), but should reject alot of the bleed. The floresent bulbs moden day scanners use , are much more powerful than daze gone past.... so betwix the two ( hardware and hi-res software ).... you have your work cut out for you ... to scan a magazine, that already suffer's from "bleed-thu" --- I know--been there--done that ----and am presently trying to deal with it myself :- (( Try Black paper as a backer Reeko

Your scanner should adopt to the lower overall brightness automatically. Womo
