Digital BW, The Print

Bob,

I am guessing you are working on a PC. What program are you saving your 
images from? If it is Photoshop, why PNG over, say, compressed TIFF? 
Tiff is a popular enough format, but I would guess that as long as Photoshop 
can read it, any lossless, compressed format should do the trick.
Also, Genuine Fractals offers a lossless option that may have merit.

Maybe if you give us an idea of what you are trying to do with your images, we 
can offer more specific advice. Are they grayscales? what MB sizes? are you 
trying to create an archive segmented  across several discs? will you be using 
Stuffit?  etc etc.

Also, since this list specializes in monochrome digital printing, is your 
question ultimately about making such prints? If not, there may be more 
specialized lists that deal with archive management issues.
