UV Layout | Export colors only, not mesh lines for texture

I have a model that I have assigned materials (just colors) to. I would like to unwrap mesh, and export the uv layout with the colors only, not the mesh showing up with it so I can then modify the png file and apply as a texture map later. Any ideas?

Render / Bake.
Bake the object texture to an image and save the image


In UV/Image editor use the UVs/Export UV Layout option. If the faces have different material colours this will show up in the export. If you don’t see this option then enable the UV Export addon

Thanks Richard. I do have the UV’s/EXPORT UV Layout option and this is what I need, but I need the image to save without the mesh shown. I need it to save with colors only.
