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.
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.
3.
When you design the document in a DTP application, use low-
resolution 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: 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 .
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.
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.
