At work I deal almost exclusively with 600dpi bitmap / monochrome scans which I assemble into pdfs.
I tend to use photoshop to get things ready, at the right size, as a bunch of tifs, then I use acrobat file->merge files into a single pdf to make a pdf.
My scans are all A4 sized at 600dpi. I find them a bit sluggish to open and view in acrobat, despite having a superfast computer. Not really slow, just not as fast as other pdfs when I flick the scroll wheel. I wonder what is the best way to optimise my 600dpi images in acrobat so they display a little faster, without reducing the quality too much? Perhaps it's a file compression thing?
If anyone has any good tips I'm all ears. Thanks
