Annotations are placed based on coordinates, and in some circumstances, content underneath the annotation may shift. This can be a particular problem when a redaction annotation shifts, potential exposing sensitive information. For example, if a document contains text data and the font used in a document is not available to the OutsideIn rendering engine, then a suitable substitute will be used. Font substitutions can cause a document to be unreadable, create incorrect text formatting, or cause shifting of data and repagination on text documents, including potentially exposing redacted content.
If annotations become misaligned and expose text they originally covered, ensure that a consistent set of fonts is being used across the servers and clients. For information on font errors, see "Font Errors".
