Hi, Georgina. It sounds like you're working with an interesting book. (smile) Have you considered trying greyscale to see if that makes a difference? Sometimes it does the trick when using normal threshholding doesn't. You might also be scanning a page with a drawing or photo on it when you get the 89 percent accuracy. Do you think that's a possibility? I don't know what you're scanning, so I'm mostly shooting in the dark here. -- Monica Willyard Visit my blog at http://www.scannersguild.com To unsubscribe from this list send a blank Email to bksvol-discuss-request@xxxxxxxxxxxxx put the word 'unsubscribe' by itself in the subject line.
