Each week, I have to send out a PDF screenshot of several graphs to a large distro. When I view these graphs in Excel, all the axis lines show and look clean. When I save/print as pdf in Excel (Office 365 ProPlus) and then open in Adobe, my axis lines are distorted near where my lines or data points are. This is so frustrating. I tried thickening the axis lines, which helped a little, but it still looks very slipshod. I think this is probably an Adobe issue, since the issue is minimally present in Chrome's pdf viewer and not at all in Edge. However, a lot of people at my company use Adobe. Does anyone know of any Excel tricks to preserve image integrity when printing to PDF? Any help appreciated.
