This will be "on topic" for anyone contemplating doing scans of OM
brochures to submit to the OM online Library, but "OT" for any others
- little or no OM content.
********************
Actually I would advise NOT using the Acrobat PDF Writer, but rather
the Acrobat Distiller program that also ships with Adobe Acrobat.
PDF Writer will do a reasonable job of converting text based docs to
pdf, and is quicker than Distiller, but Distiller creates better
final quality pdf files (especially where there are
graphics/pictures), and achieves a better compression at the same
time.
From the collection of TIFFs you have (they would be about
20-30Mb/page) name them sequentially, then use Adobe Acrobat to
import them (File->Import->Image). Save this pdf -it will be huge at
this stage (about 500-700Mb). From this, print the file *NOT* to a
printer, but to a Postscript File. This will create a 600-700Mb file
with a ".ps" suffix. This postcript file is the file that you feed
into Distiller. You need to set Distiller to create the pdf at 150dpi
resolution. It will turn out a lovely 10-11Mb pdf file that is your
finished product.
You can see that the various stages of the process take up quite a
bit of room on the hard drive and will take a while for your cpu to
churn through all the various creating stages.
For one VisionAge issue of say 35 pages, you are looking at just over
2Gb of hard disk space...
Original TIFFs 35 x 20Mb = 700Mb
Initial PDF =700Mb
Postrcipt File = 700Mb
Final PDF = 12Mb
TOTAL upwards of 2.1Gb
I would recommend that no matter how tempted you are to trash the
original TIFFs (to save space) once you have moved on from step 1 -
DON'T !! Burn them off onto CD/DVD or copy to tape if you can.
As to the moire problem you are having, I find that some source
material is worse than others. My Canon 630 USB scanner has a
"descreen" option that slows down the scanning time but can remove
these patterns. I don't use it all the time as it is only a problem
for some source material. I would recommend that your initial scans
be done at no more than 600dpi. I do mine at 300dpi. The OM desktop
wallpaper initial scans are done at 600dpi but that is so that I can
physically squeeze out a larger (pixel wise) image for list members
with larger screens.
let me know when you are done with Issue #3 and I'll post it on my
site if you like. I don't have issues 1-9 (inclusive) so will be
relying on fellow list members to fill in the gaps where they can.
Mark Dapoz has contributed Issue #1, and if you are working on Issue
#3 we will only have 7 issues left to get. I have Issues 10-18
inclusive.
If you don't want to purchase Adobe Acrobat, but can burn the orig
TIFFs onto a CD (or 2), I'd be happy for you to post me the CD and
I'll do the converting etc. Let me know first so you make the right
format CD (I have a Mac).
hope this helps.

<<Now the question is: Wich is the program to make it a pdf?>>
You need the Adobe Acrobat Writer to make PDFs:
http://www.adobe.com/products/acrobat/main.html
It's $249 list, $206 at eCost:
http://www.ecost.com/ecost/ecsplash/shop/detail.asp?dpno=43103
If you do not want to pay that, I have it and would be glad to
compile your Tiffs for you if you can get me the files (ftp, CD-ROM?)
