To flatten transparencies in a PDF input document, add one of these "quality" settings to your JSON profile file. If you don't include the "quality" setting in your JSON profile, PDF Optimizer will not flatten transparencies.
Note that the printing.json JSON profile included with the software provides the "transparency" statement by default at the end of the file.
|quality||The resolution level to use when flattening transparent objects. The higher the level of quality, the better the final output in print or in a browser window. But the resulting PDF document will also be larger.|
|low-quality||Line art and text 288 DPI, gradients 144 DPI|
|medium-quality||Line art and text 300 DPI, gradients 150 DPI|
|high-quality||Line art and text 1200 DPI, gradients 300 DPI|
