Transparency effects are not printing satisfactorily.
Many of the DesignMerge Print Drivers provide the ability to produce industry-standard optimized VDP output. This reduces the size of the output and enhances the performance of both DesignMerge and your digital print controller. However, this optimization may prevent some transparency effects from printing successfully. In that case, you will prefer to use a DesignMerge Print Driver that retains transparencies in the output and instead let the digital print controller do the flattening, or use a DesignMerge Print Driver that produces non-optimized output, such as the DesignMerge PostScript Driver. For more information to select an appropriate Print Driver, see the DesignMerge Print Drivers and Transparency Effects Knowledgebase Article.
