Abstract: A client/server system for reading, measuring and displaying color density of documents located on a remote file system accessed over a WAN such as the Internet. The color density information displayed corresponds to specific coordinates of documents that are located on the remote image file servers. The invention provides means for reading, displaying and recording color density measurements of original digital images located on remote image file servers rather than representations of these digital images stored on the user's local computer or LAN. A web server application on the server side functions to capture measurement requests from one or more client applications for measuring, sending, recording and retrieving color density measurements related to specific positions of specific documents located on an image filer server.
