I've updated our servers and done some simple, initial tests; the 3.5 version is a lot faster - almost 50% - than 3.2, which is great news for us as we process thousands of pdf files every hour. At the same time, 3.5 compressed the pdf files better, again by almost 50% compared to 3.2. Great work - thank you very much!

Future Network USA needed a reliable solution for converting our magazines' high-resolution PDF pages into a format suitable for use in Zinio's digital magazines. We used PDF Enhancer to reduce the size of the files and automatically crop each page to the final trim size. PDF Enhancer will save us a significant amount of time and money each issue by allowing us to build our electronic magazine pages in-house with minimal time and effort.

PDF Enhancer supports a wide variety of options for modifying the colors in a PDF document including ICC and deviceLink profiles. Simply select the desired output colorspace. PDF Enhancer can convert to black (text-only), grayscale, RGB and CMYK. Different conversion types can be selected for raster images and vector or text elements.

Spot colors such as Pantone colors can be optionally converted to selected output colorspace or left unmodified. Advanced options include Black Point Compensation and protection of "pure" colors.

ICC profiles are fully supported. PDF Enhancer supports input, simulation and output profiles with selectable rendering intent.

PDF Enhancer includes a unique feature called Gray Reduction. During color adjustment, PDF Enhancer automatically finds gary or black text and vectors defined in any colorspace and allow you to convert them to the color space of your choice - pure gray, CMYK (100% K) or a special "Separation Black" colorspace. Use this option to fix common printing problems with documents created with Microsoft Office or similar software that defines black text in the RGB colorspace.
