This inquiry was sent to List HQ who decided the subject merited discussion online as there probably are many members who have a similar question: Here goes: It is my understanding that Pixels are for viewing and Dots are for printing. Is there any rule of thumb or some ratio that equates Pixels to Dots. For example, if a printer wants a file to print an 8 X 11 image at 300 DPI than how many PPI should the file contain? from: PhotoForumn List HQ on behalf of the person posing the question.
