If the low-resolution proxy images containing OPI comments are still present when the document is sent to the RIP, the low-resolution data will be present at the flattening stage. This will result in low-resolution output where the low-resolution images are involved. To make high-resolution data available to the flattener under this scenario, the customer should replace any images that are directly involved in transparency on the layout with high-resolu- tion versions before critical flattening and output. The customer doesn't have to replace all 56 images-just the ones involved with transparency. To save time, you can use the Affected Graphics option in the Flattener Preview palette to quickly identify the images that need to be swapped out with their high-resolution versions. A quick way to remember how to manage transparency and OPI is to remember the phrase "fatten before you flatten," with "fattening" defined as ensuring that high-resolution images have replaced all low-resolution images before output. Understanding transparency flattener presets InDesign CS comes with three transparency flattener presets built in. They are optimized for low, medium, and high-resolution output. To minimize training, the flattener controls in Adobe InDesign CS are now consistent with Adobe Illustrator CS and Adobe Acrobat 6 Professional. Adobe InDesign CS defaults to Medium Resolution for fast output on the customer's desktop printer. In a print service provider workflow, the High Resolution flattener preset is recommended (or a similar preset customized for your workflow) because the results of this preset are most likely to be press quality. Low Resolution should be used only for rough proofing or online output. While the High Resolution flattener preset is recommended for prepress output, there is a chance that some jobs may encounter output problems if, for example, memory limits are reached or the output resolutions don't match your workflow. To confirm which settings produce the best results on your equipment, run some test jobs containing transparency, starting with the High Resolution transparency flattener preset. If you encounter quality or performance issues, you may need to create a customized transparency flattener preset for your shop, as described below. You can use the Save and Load buttons in the Transparency Flattener Preset dialog box to save your tested presets so that they can be loaded on other computers in your shop or on customers' computers. It's important to understand that the process of flattening transparency can result in either vector objects or rasterized areas. This is a consequence of trading off quality against flattening speed. Of course, for service provider output, quality is the highest priority.

for low, medium, and high-resolution output. To minimize training, the flattener controls
in Adobe InDesign CS are now consistent with Adobe Illustrator CS and Adobe Acrobat
6 Professional. Adobe InDesign CS defaults to Medium Resolution for fast output on the

tener preset is recommended (or a similar preset customized for your workflow) because the
