A controlled image including a predetermined graphic symbol, for example a signature on a check or other document, is produced in a web-based imaging environment. From a client program, for example a user's browser, a source service is accessed and dynamically generates under interactive control of the client program a printable version of the controlled image including the predetermined graphic symbol, which references a particular symbol set, for example a font. The printable version is referenced from a composition associated with a user's identity, e.g., an imaging store. A destination service representing a production device is accessed from the client program and then retrieves the printable version. Only if the destination service contains the particular symbol set will the controlled image be produced including the signature or other predetermined graphic symbol. Otherwise the image can be optionally produced including a substitute symbol, e.g., “VOID.”
