The basic answer is that DPI in an image file *means nothing*. Really. Absolutely no meaning. It conveys no information. It serves no purpose. The only effect it has is to cause confusion, such as this thread, over and over and over again. > If the answer is yes, then... So I think of the answer as being "no". But it depends exactly what you mean by the question. Having more resolution, up to a point, will result in better printing. > Is this in fact the best way to change the ppi of an image? Or dpi if > you are considering, as I do, each pixel to be a digital dot. The "do not resample" box you mention, and which I mentioned in a previous message, is the trick, if you need to produce a new file with different DPI encoded in it. But I've never ever seen a situation where that mattered -- except when dealing with ignorant people I was sending a file to, where it was easier to change the number than teach them their jobs. You may well need to deal with that situation also, of course! So that's the best way I know. -- David Dyer-Bennet, dd-b@dd-b.net / http://www.dd-b.net/dd-b/ John Dyer-Bennet 1915-2002 Memorial Site http://john.dyer-bennet.net Dragaera mailing lists, see http://dragaera.info
