This feature monitors and modifies PostScript requests for line thickness, and ensures that the smallest thickness request is 0.216 pt or larger so the lines will appear even on high resolution devices. At 2400 dpi, one device pixel is equal to 0.03 pt. At 300 dpi, one device pixel is equal to 0.24 pt. This is because the PostScript requests the smallest possible line (for example, a single device pixel). When device resolutions increase to 2400 dpi, these thin lines seem to disappear, especially on a printing press. Many legacy applications generate PostScript that draws very thin lines (hairlines), expecting that the output will be appropriate for 300 or 600 dpi devices. The PageMaker bug would cause tinted images to be output at 100% intensity, rather than as set in the document for composite workflows. Recent additions to this feature support Adobe PageMaker colorized images correctly. This feature corrects several bugs in that engine. The Prinergy normalize function uses an Adobe OPI merging engine. This feature rewrites some ArtPro procsets more efficiently to ensure better performance. It is not necessary to control flatness if the device resolution is greater than this value. Note: The maximum resolution that still requires flatness control is 600 dpi. This feature assists these legacy files by pretending to increase the flatness value, but letting the RIP render paths as smoothly as it can. Many legacy files still contain high flatness values, but newer RIPs (and the Distiller) can cope without raising the flatness value. Unfortunately, this would often force the RIP to render paths as a smaller number of line segments, resulting in curves which appeared flat (for example, circles that appear like stop signs). The workaround had been to set the graphics state flatness to larger and larger values.

Many older Adobe RIP products were unable to render complex paths (often generating limitcheck errors). This feature enables or disables flatness size changes present in the input file, and helps avoid problems where legacy PostScript files set the flatness to a very high value. The names of the features appear in the Acrobat Distiller startup messages box. The Kodak Distiller Assistant features solve problems that Acrobat Distiller may encounter when distilling PostScript and EPS files to PDF.
