preserving / ressurecting old docs?

Besides, some of the legends in the drawings are in letters that are very tiny, and there's always the line art itself... scaning at 70dpi would be next to useless. Excepting my own mother ("Breeches of Silver", which she "typeset" for the Rev. Richard Starling on her 4Mb Mac SE about 15 years ago). She did the photo-readies which were sent to a "real" printer for offset production. But seriously, no... it's not ordinary to make books on a laser printer, partially because the ink technology isn't as stable as what is used in offset presses (reflowed resin, vs. oil-based printing inks). The resolution isn't the primary issue. Hardly. With cheap 80Gb disks and CD burners, storage space really isn't an issue compared with the value of the data. I personally have a couple of boxes of PDP-8 docs. I have been digging around on pdp8.net and so far, have only turned up a couple of docs that I have that aren't up there (and yes, I will be scanning mine at 300dpi if not 600dpi ;-) Information theory suggests that sampling any signal at more than twice its frequency does not result in aquiring any additional content. For pictures, I scan at well over the "standard" web resolution of 72dpi, but I do reduce the scans to approx 72dpi for display on the web (and at much lower for thumbnails). For printing, I have to agree that 300dpi is a good compromise between file size and quality. Trying to read the small print on a DEC maintenance print that has been scanned at 300dpi is nearly impossible. -ethan ===== Visit "The Seventh Continent" http://penguincentral.com/penguincentral.html __________________________________________________ Do You Yahoo!?
