Drop shadows, vignettes, translucent objects, objects softly blending into each other and other effects based on transparency have added a great deal of creative freedom to designers.
Unfortunately, many production systems are poorly prepared to deal with these cool features. The only workaround: “flattening” the PDFs.

callas pdfAutoOptimizer 2 allows you to flatten files fully automated, handling both CMYK and spot colors, while keeping most raster, vector and text elements intact.
While pdfAutoOptimizer 2 overcomes most of Acrobat's limitations on top of fully automating the flattening process, callas pdfAutoOptimizer allows to maintain flexibility in design and safeguard investment from the past.
