! Actually in prepress workflow all the marks that are included in project are not only useless but in most cases obstruct. All the marks needed will be included later in prepress process. The perfect made project must be set with trim box and bleed box if needed and no marks that interfere within the bleed box. Crop marks can be an exception if they are set right way.

Please note that if some marks are needed for your own purposes you can set them outside the bleed box.
