Both programs are designed to smoothly work together. In the following, we describe how OPI will behave if you are working with QuarkXPress and use ColorSync 2 XT.
- First of all, when talking about co-operation, we
assume that ColorSync 2 XT has been activated in the ColorSync 2 dialog in QuarkXPress.
- Whenever ColorSync 2 XT is active, the program will take care about the matching of colors you have defined for text or graphics in QuarkXPress. OPI does not affect this process.
- The printer and proof profiles you have selected in the ColorSync 2 dialog, are always valid. They replace the printer queue settings in the EtherShare Admin dialog and thereby automatically activate color matching for this specific printer queue (compare paragraph Default Printer Profile: in chapter 6.5 "Printer queue settings").
- Whenever you switch off color matching for a single image (which can be done using the Match button in the ColorSync 2 dialog), this image will be excluded from matching, even if the matching process is performed by the OPI software.
- Raster-based EPSF files are always matched by the OPI software, because ColorSync 2 XT is not able to handle EPSF files.
Working with high-resolution images
By default, OPI does not replace high-resolution images for printing. So, if you place high-resolution images in a QuarkXPress document, color matching will be performed by ColorSync 2 XT on the Macintosh computer. ColorSync 2 XT will use the ICC-profiles that are tagged to the high-resolution images (embedded or by reference) - if there are any. For every image that has not yet been tagged, you have to select an image profile using the respective features in the
ColorSync 2 dialog.
If you switch the
Replace Images option to
All on your server (see chapter
6.5 "Printer queue settings"), OPI will replace all images for printing - high-resolution images included. In this case, color matching will be performed by the OPI software, but will nevertheless be based on the settings in the
ColorSync 2 dialog. OPI will use the ICC-profiles that are tagged to the high-resolution images (embedded or by reference) - if there are any - or use the image profiles you have assigned to the images in the
ColorSync 2 dialog in QuarkXPress. You will get an error message if the high-resolution images that are to be sent to the printer do not have an image profile at all.
Working with low-resolution layouts
In case you place low-resolution layouts in a QuarkXPress document, color matching will - in particular situations - be performed by ColorSync 2 XT on the Macintosh
and by the OPI server simultaneously.
If the low-resolution image already includes an ICC profile (embedded or tagged by reference), you cannot select an image profile in the
ColorSync 2 dialog. During printing, the image will be replaced by OPI and the profile tagged to the high-resolution image or layout image (if printing layouts) will be used for color matching.
If the low-resolution image does not yet have an ICC image profile, you may select one in the
ColorSync 2 dialog. This profile, however, only serves to match the layout correctly on the monitor, it will be skipped when the image is replaced by OPI during printing. OPI will then use the image profile of the high-resolution image for color matching or will display a warning if you print layouts, because the layout file does not have a tagged profile and OPI has to use a default profile instead.
Note: If you use one of the Omit... options in the
QuarkXPress print dialog, images that are replaced on the OPI server (layouts only or all images - depending on your printer queue settings) will also be matched on the OPI server.
Note: For more information about how OPI handles image profiles and executes color matching, you may also read chapter 5.6 "About how OPI 2.1 applies color matching".
