Can I add a colored bar across the top of my PDF doc as a headers?

Hi Bruce,
One other point. You may prefer to do everything in Acrobat, i.e., not use an imaging program to create the colored bar. If so, here are the instructions to create it in Acrobat DC.

First create a new PDF with a blank page:

Tools
Create PDF
Blank Page
Create

Second, create the colored bar in it:

Tools
Comment
Draw rectangle
Change color (opens color dialog)
Fills (pick color)
Borders (pick color)
Opacity (move slider)
Change color (closes color dialog)
Position mouse at upper left starting point
Drag to lower right until you have line size you want

Save that file as a PDF and then use it as the File for the instructions in my previous post. When you do it with this method, I suggest (1) making the bar the size you want it to be on the target PDF; (2) positioning it where you want it to be on the target PDF. That way, in the Add Watermark dialog, you can (1) un-tick the "Scale relative to target page" box...it will be the size you want; (2) not have to adjust the Vertical Distance and/or Horizontal Distance values...it will be in the position you want.

Update: I decided that this is a lot easier to explain in a video, so I just published a five-minute EE video Micro Tutorial with the all-Acrobat solution:
