Multiple raster resolutions on one page

In Calamus documents you can assign completely different rasters to individual pages or even individual frames. This is not so simple in PostScript and is not supported by PostScript export in Bridge. If you require special raster types for individual frames, we recommend therefore that you pre-rasterize them with the Bridge module (Convert function of the Convert to bitmap graphic panel):

• To do this, just set the desired raster for a frame in the Raster generator.
• After this convert the relevant frame in the Bridge module to a monochrome image frame using the Calamus rasterizing. (With coloured graphic frames we recommend you use the analogous conversion to C M Y K (4 frames), Monochrome. This raster image data is then exported quite normally by Bridge with any other data and will not be rasterized further by external PostScript RIPs.
