how to do trapping manually in indesign

[lychi]

hi all:

does anyone know how to do trapping manually in InDesign? for example, I have an black image (tiff file in bitmap mode) print on a 15% pantone color. but the InDesign automatically set to overprint (I print separations and found out that the image was not knockout. but all other black text knockout on this 15% pantone color) does anyone know how to knockout image in Indesign?

thanx for all the input.

If your sending the file off to a printer to get printed they will trap your files to their specs that work best on their presses. Also is it possible you have overprint fill checked on in your attributes when you select the object.

Even if you manage to get it to knock out, I don't think you're going to be able to do the trapping you want (since you surely don't want the colors to just butt), at least not in default InDesign. Setting your own overprinting stroke to trap, for example, works fine for vector images but you've got no stroke with your bitmap, and I don't think there's a manual setting for one in ID.
