Zevrix Solutions (http://www.zevrix.com) has announced PDF Checkpoint 1.6.1, a maintenance update to its PDF preflight and conversion solution for Mac OS X.

The software automatically preflights, exports as images, splits and optimizes Adobe PDF files. The program is equally suitable to process hundreds of files as well as single PDF documents. The new version improves PDF conversion to TIFF and PNG images with preserved transparency and addresses some issues related to output image resolution and size.

PDF Checkpoint can be purchased from the Zevrix Solutions website for US$49.95, as well as from authorized resellers. It’s bundled with free Graphic Inspector software (a $40 value). The 1.6.1 update is free to licensed users. A demo is available for download. PDF Checkpoint requires Mac OS X 10.5 or higher (some features require Mac OS X 10.7 or later).
