To print targets, you must not use any color management (would defeat the purpose if you applied a profile to them). This means they won't be in your working space (or any other space). The targets themselves should have no imbedded profile, and if Photoshop is set up right, you should get the question this document has no profile with 3 choices when you open them. You want to choose the one that leaves the document unmanaged.
If you do not see the questions, make sure in your color settings in Photoshop you have checked the boxes about profile mismatches.
Adobes utility I believe is free and does not require a license for any particular version of PS, which is the easiest way to insure you are sending the files to the printer correctly.
