PDF washed out in Modelspace

[AllenJessup]

I've inserted a PDF underlay that looks washed out in Modelspace. In a Paperspace viewport it looks fine. I thought it might be a transparency issue. Transparency for the layer was 0. I; changed the object transparency to 0, checked the contrast was 100 and the fade was 0, even set a different color for the layer. Nothing improved the look of the PDF in Modelspace

If I go to Modelspace through the layout. It still looks fine. But if I maximize the viewport, It will be washed out. This may be a known issue. I rarely attache color PDF's. I have the original Orthos as JP2 files. I need the PDF for additions by others. It will work since I'm plottng from Paperspace. But it looks weird while drafting my additional work.

I wonder if it is related to this post Allen.

It might be. But I can't get the hotfix to install.

It isn't that problem because I inserted the same aerials covering that area and they look fine in modelspace.

Allen,

Can you save the PDF as an image, and does the same washout happen?

Change your modelspace background color to white.

@wlewis I'll give it a try. But at this point I've abandoned the PDF and brought in the original aerials. I duplicated the little work that had already been done and have the preliminary plot we need for the submission on Monday.

@tcorey That does it. But if I have to set my background to white just to see it correctly. I'll stick with using Raster Images. Do you know why this happens. I do see that white background for titles and legends appear black. I'm guessing it reads pure white "background color".
