A system and method for automatically adding a color bar as a rendering job ticket attribute and dynamically generating the color bar based on the rendering job attribute. The color bar can be added in association with the rendering job ticket along with a set of sub-attributes that include parameters associated with the color bar. The dynamic color bar can be automatically configured to include spot colors associated with the rendering job and the parameters can be specified in a device-independent way. Upon receiving the rendering job with the dynamic color bar attribute, the rendering device can render each page of the job in association with the color bar. The dynamic color bar generation instructions can be detected in the job ticket generated by a print driver thereby enhancing the use of the color bar in a color rendering application.
