PDF Checkpoint 1.7.14 Improves PDF Image Preflight Posted 11/28/2015 at 19:32 UTC in Mac by gnye@amdesign.net | Permalink | Tweet Toronto based Zevrix Solutions today announces PDF Checkpoint 1.7.14, a maintenance update to its PDF preflight and conversion solution. Remarkably fast, PDF Checkpoint automatically preflights, exports as images, splits and optimizes multiple Adobe PDF files. The software can also convert the color mode of PDF documents, assign ICC profiles, downsample resolution and compress images. The new version improves reliability of image preflighting and fixes a stability issue on Mac OS X El Capitan.
