This chart was created to assist you in determining what file size is good for scanning and printing. Although it is sometimes possible to enlarge a 200dpi file, please note that most methods of printing technology at HKI require a 300dpi file and therefore we usually recommend a scan at the 300dpi size. If you have specific questions about a particular job, please contact us.
