PrintTrapping.BlackWidth property
Specifies the amount that black spreads into another color during in-RIP trapping
Syntax:
Property Get BlackWidth() As Double
Property Let BlackWidth(ByVal Value As Double)
Remarks:
The BlackWidth property specifies the black-trap width when trapping to black.
Examples:
The following VBA example specifies the PostScript.Level property as level 3, changes both the trapping and the black widths, and then displays the Print dialog box.
Sub Test()
Dim s As String
With ActiveDocument.PrintSettings
  .PostScript.Level = prnPSLevel3
  With .Trapping

 .BlackWidth = 0.6 / 72 * 254000

 .Width = 0.35 / 72 * 254000
  End With
  .ShowDialog
End With 
End Sub
