What it does

Checks if trim marks found in the PDF match the trim box and/or the bleed marks match the bleed box.

How to proceed

Indicate which marks you want to check: trim marks, bleed marks or both.
To help PitStop detect the trim marks, specify the potential color of the marks, by choosing one or more of the following:
- 400% CMYK
- Separation All (registration)
- 100% black
- A specific color
  In case of a specific color, do one of the following:
  - Select a color space from the list and use the sliders to select the appropriate color.
  - Click and select the appropriate color.
  - Select an object with the Enfocus Selection tool and click to grab the fill or stroke color from the selection.
If desired, specify how much the marks are allowed to deviate from the expected position:
- The unit is the unit set in the PitStop Preferences (Units & Guides category), for example: cm or pt
- The maximum value is 2.7 pt; if you enter a higher value, it is automatically reset to 2.7 pt or an equivalent value, if you're using a different unit.

Example

In the image below, the red marks are detected as trim marks, although the position of the vertical marks in the top and bottom left corner is not as expected (they are not exactly on one vertical line). In this case, the deviation (= difference between the position of both marks) is less than the specified threshold.

Remark

A filled path with 3 lines is accepted as a trim mark if:

The color is as specified in the attributes of this Action.
It has no dash pattern.
The 4 points of the 3 lines are a rectangle.
The path is closed.
The width is between 0.1 and 2 pt.
The length is between 8 and 40 pt.
