[WEB4LIB] Re: Best Scanner Settings for PDF files

[Masters, Gary E]

I have a comment and a question.

My comment is that hard disk space is not expensive.  Big files are not what
they used to be.  What size of file are we talking about?

My question:  Is there a compressed PDF format, or is it already compressed?
I know that some of the new formats are driving compression into the ground.
Look at what DivX can do.  I am amazed - or is that gain just for motion?

Regards,

Gary

	Hi Giz,

	Are you all using Distiller to compress the files?  In any case, we
are
	scanning at 300 dpi 2 bit (line art).  Once we've got them in at
this
	level, we bring them down to 200 dpi in Distiller.

	It's important to play around with the settings in Distiller till
you've
	found the lowest acceptable point while at the same time of course
	maintaining legibility.  Distiller's defaults genenerally aren't
good enough.
