There are still some situations that cause problems when working with EtherShare OPI 2.1. In most cases, this is due to application specific incompatibilities. The following list of known restrictions is not "everlasting". You should always compare it to the latest README files issued by HELIOS in order to find out whether a problem has already been fixed.
EtherShare OPI 2.1 does not support layer masks saved in Photoshop Native format. When using layer masks in Photoshop and saving the images as Photoshop Native, blank layout images will be generated. Please apply any layer mask to its layer and remove it before saving the image.
EtherShare OPI 2.1 does not fully support PICT images based on object descriptions other than PixMaps. Such images may be created by applications like Illustrator or FreeHand and may cause incomplete previews.
EtherShare OPI 2.1 will not work as expected if mounting NFS volumes using the UNIX automount facility. Please hard mount NFS volumes by using the mount program.
On Data General systems, EtherShare OPI 2.1 will not run under the operating system version DGUX 5.4.2. You will have to upgrade to version 5.4.3 or newer.
We found that QuarkXPress 3.x matches spot color names found in placed EPSF files to its own ones by comparing the names of the imported colors with the built-in color tables. The program sometimes matches names which are only partial identical and then continues using its own names when editing colors and printing. This may result in missing spot color plates because the plate printed by QuarkXPress does not match the spot color name in the image. To avoid such problems, you should rename the spot colors in your images.
An image generated by Adobe Photoshop includes a channel named "PANTONE Orange 021 CVC". QuarkXPress matches it to "PANTONE Orange 021 CV" in its own table and uses this name further on. While printing, a plate named "PANTONE Orange 021 CV" will be printed but no OPI image replacement can be done because of the different name stored in the image.
For PC-EPSF format DCS images in QuarkXPress, printing
Separations will cause problems when you include images in the print job.
Omit TIFF & EPS must be selected. Otherwise, QuarkXPress will generate bad PostScript.
We found that Adobe PageMaker 6.x silently removes the preview part of placed EtherShare OPI 2.1 EPSF/DCS layout files during printout. On EtherShare printer queues with OPI and
Print Layout Images switched on, no previews of EtherShare OPI 2.1 layout images will be available, so that blanks will occur on the printouts. Printing high-resolution images on an OPI printer queue will work fine.
When placing EtherShare OPI layouts in PC-EPSF format using a compressed TIFF screen preview, the preview will be displayed distorted on the monitor. Printing will work properly - unless you choose to print
Separations. In that case, PageMaker 5.0 will generate bad PostScript.
When scaling a page for printing (to more or less than 100%), OPI TIFF image replacement will be done but the images will keep their size as if the page were printed 100%. This is also due to a problem in PageMaker 5.0.
We found that Aldus FreeHand 3.1 may damage the binary parts of OPI 2.1 layout files placed in FreeHand 3.1 documents. This will cause partial printouts on EtherShare OPI 2.1 printer queues. The same applies to EPSF files exported from FreeHand 3.1.
