This topic explains the three options in output process templates that position sheet marks: Locate Sheet Marks Adjacent to list, at Distance box, and Justified list.
Using these three options, you can place a sheet mark at various positions on a press sheet or plate. Before making your selection, you must know where you want the sheet mark to appear, the size of your press sheet and plate, and the location of the lead and tail clamps. This is particularly important when placing the sheet mark on a plate.
Important: Use the Virtual Proofing System software to check the sheet mark placement. Alternatively, you can output to a low-resolution TIFF file and view the sheet mark placement in the Copydot Toolkit software.
Locate Sheet Marks Adjacent to
The Locate Sheet Marks Adjacent to list allows you to place the sheet mark on the left, right, bottom, or top edges of the plate. The sheet mark rotates when positioned on the right and left edges, but not on the top or bottom edges.
The at Distance box determines how far to position the sheet mark from the edge that you selected in the Locate Sheet Marks Adjacent to list. The distance is shown as A in the following diagram.
Important: When placing the sheet mark on final output, carefully calculate the at Distance value. Otherwise, the sheet mark may print beyond the edge of the press sheet.
Selecting Right or Left in the Justified list places a sheet mark flush against the edge of the plate, with no border or spacing. In some cases, you may inadvertently place the sheet mark in the nonimageable area under the lead or tail clamp.

Putting it all together
These diagrams (not to scale) show possible combinations of the Locate Sheet Marks Adjacent to and Justified options. Assume that the at Distance value is 6.3 mm (0.25 inches) in all cases.
The following diagram shows sheet marks placed on a plate.
Note: In some combinations, part of the sheet mark is located in the nonimageable area under the lead or tail clamp.
