254 Chapter 6 - Production Printing Creo APR and OPI File Formats Creo APR and OPI function identically on the Spire CXP8000 color server. Creo APR low-resolution files have an *.eps extension in Windows and an *.e extension on the Macintosh, while OPI low-resolution files have a *.lay extension. The Creo APR and OPI workflows support Creo Continuous Tone, EPSF, Jpeg, PDF, DCS1, DCS2 and TIFF high-resolution file formats. You can use either the Creo APR or OPI workflow, depending on your high-resolution file type. Preparing to Print Using Creo APR or OPI 1. Create low-resolution files from high-resolution files. Note: You can use the PS Image Exporter Plug-In in Adobe Photoshop to create Photoshop Image (APR low-resolution) files. You can either install the PS Image Exporter Plug-In from the Spire CXP8000 color server Documentation and Utilities CD-ROM, or download it from the Creo website at https://ecentral.creo.com/ecentral/self_support/downloads.asp. 2. Export each image file as a low-resolution *.e file-for example, a file called duck is exported as duck.e. OPI images can be created in other applications or can be provided by a print service bureau. Make sure that you have created or obtained the desired image files. Notes: • A PostScript image (*.e) file is a low-resolution preview of the original high-resolution file. It contains preview information saved at 72dpi in black and white or color. Also, it contains pointers to the location of the high-resolution Image. • APR low-resolution files have a. "*.e" extension on the Macintosh and an "*.eps" extension in Windows. OPI low-resolution files have a "*.lay" extension. 3. When you design the document in a DTP application, use lowresolution files. 4. Perform detailed graphic work on the original high-resolution file. Only use the low-resolution file for positioning, rotating, scaling and cropping. Note: Once you create the low-resolution file, do not change the name of the high-resolution file. This is the file name for which the Spire CXP8000 color server searches.
