In Brisque 3.0.38 and 4.0, bitmap TIFF files switch polarity and the monochrome image becomes inverse


Product		Brisque 3.0.38 Update CD2 and Brisque 4.0
Platform		Version 3.0.38: E30 - Victory 43P-140 - Tiger1 43P-150 - Tiger2 F50 - Wildcat (2 and 4 CPUs) Version 4: E30 - Victory 43P-140 - Tiger1 43P-150 - Tiger2 F50 - Wildcat (2 and 4 CPUs) 44P-170 - Hammerhead 6F1 - Condor (2,4 and 6 CPUs)
Operating system		IBM AIX 4.2.1 or IBM 4.3.3

Symptoms		Running the Normalize with CCITTG4 for Monochrome images causes the Bitmap TIFF file to switch the polarity and the monochrome image becomes inverse.

Cause		There is a problem with Bitmap TIFF files embedded in the PostScript file. The problem will be fixed in the next Extreme Version.

Solution		Set the ZIP Compression method in this option. In the Normalizer dialog box, Compression section, select the Compress ZIP option instead of CCITT Group4. In the RIP window's HighRes Handling dialog box, clear the OPI option. The PDF generated from distiller or normalize has to RIP without OPI comments in the HighRes Handling dialog box.
