No, I have not tried that because I don't know what I am doing. I suppose
that if I try it on a book that has some pages that are scanning okay and
some that are not I would have to change it for each page?

Hi, Roger,
Have you ever experimented with the settings in the Scanning settings under
the Settings menu?
In that submenu, there is an option for "scanning contrast". There are
options for automatic contrast, normal contrast, darken page, and lighten
page.
But below those choices, there is a list of numbers from 1 to 255. Using
one of these numbers allows you to darken or lighten the page beyond the
perameters
in the other options.
127 is the number that is similar to normal contrast.
One time I had a book that would barely scan using automatic or normal
contrast darken page or lighten page. The letters either ran together or
created
garbage. I played around with using the numbersdarkening the page by using
number 25 and the book scanned really well.
So if you have not tried these custom settings for scanning contrast, check
it out. Hope this helps.

Subject: [bksvol-discuss] Scanning Old Mass Market Paperbacks
Some of you will recall that when I first started scanning books for
Bookshare I was looking around for something to scan and found an old mass
market
paperback
that was published in 1963. Scanning it turned out to be an impossible
task. Since then I have scanned and submitted several hardcover and trade
paperbacks
and learned some techniques for scanning. One of those experiences was a
trade paperback that was turning out terrible, but when I scanned one page at
a time and checked each page before going on to the next one I was able to
rescan the difficult pages as I came to them and some of them I rescanned
over
and over before I got it right, but I finally did get it right. Since that
time I have adopted the one page at a time method for all my scans. I
remember
that even though that book was a trade paperback the pages felt like they
might have been made of mass market quality paper and that might have been
the
problem. Anyway, now that I have some experience behind me I have laid my
hands on several older used mass market paperbacks and I have been
experimenting
with them. So far I have found only one page that scanned perfectly. Other
pages have numerous errors throughout them, but I think they can be
repaired.
Still other pages scan nothing but garble and remain garble no matter how
many times I rescan them. I had someone with sight take a look at them to see
if there was a difference and I was told that they looked pretty much the
same except that the pages that would not cooperate at all might have
slightly
more age darkened paper. Since the variation occurs in the same book I
would hate to start scanning a book that started out okay and then get to the
middle
of it and find out that I could not continue. If I do scan one in its
entirety I want to assure myself that I can correct any difficult pages and
finish
the job, so I want to experiment some more before I start. Does anyone have
any advice on scanning an older mass market paperback? I am using Open Book
6.0.
