The Convert Color with Equinox and Optimize PDF Separations tickets have been added to a trapping workflow and now the files are not trapping correctly.
A workflow made to trap files works as expected until the Convert Color with Equinox and/or the Optimize PDF Separations are added to the workflow. In some cases the technical inks, especially a "die" or "cut" ink may be considered in the trap.
Check the location of the Convert Color with Equinox and Optimize PDF Separations tickets in the workflow. The Optimize PDF Separations ticket should be after normalizing and trapping, and before the Convert Color with Equinox ticket.
Tasks, such as PowerTrapper, look at the XMP information in the file to determine if an ink is defined as Technical or not. A non-normalized PDF file does not have XMP information yet. So, by normalizing the file, the XMP information is added and the Optimize PDF Separations task will then update that information based on settings defined in the ticket.
The Convert Color with Equinox essentially flattens* the file to convert the inks, based on the profile. A flattened file will trap differently than non-flattened file causing unexpected results. For this reason, the Convert Color with Equinox ticket should always be applied after the file is trapped.
*As of version 14.1, there is an option to turn off the flattening. Although this is not recommended, it can be an alternative solution.
