How to get rid of the inner bleed line in PDF exported from InDesign

[RK2020mm]

I want to include document bleeds in the exported PDF file without bleed or printer marks. I don't have any marks checked (except for the 'include document bleeds') yet the exported PDF has black line on the spine line. You can see it in the attached sample page. I know they will most likely be trimmed off in the final printed document, but they still bother me. Does anyone know how nd where I need to turn this off? Thank you!

Is the screenshot from Acrobat or InDesign? In InDesign the spine is always visible.

It's pdf, just one page from the document. It's not the spine, it's the bleed line. I actually found out what the problem was after I posted 🙂 Apparently, I had another layer in InDesign with a red trim box expanding further than my own bleed box, and it was showing out in pdf. The file wasn't created by me initially, so I didn't think to check the layers. Now that layer is gone along with all the bleed lines I didn't need. Thanks anyway!

Hi @RK2020mm , When you Export a PDF you set the Bleeds in the Marks and Bleeds tab—uncheck Use Document Bleed Settings and set the Bleeds to 0:

For an existing PDF you can set the bleeds in AcrobatPro via Print Production>Set Page Boxes
