I am having a problem with Lightroom CC 2015.2.1 where I got a very pale blue color being printed in the space between the edge of the image and the edge of the cell. I am not printing a page background color nor any of the other page options.
OS X 10.10.5 with an Epson 3800. It occurs to me that I recently switched to the Canson Platine paper, which is a luster paper that uses the photo black cartridge. I didn't have this problem with Hahnemuhle Photo Rag, which uses the matte black cartridge. On the otherhand, I also use the Kirkland Glossy Photo Paper and I don't have the same problem with that one.
The obvious solution for now is to make sure the cell size is exactly the same as the image size, but it annoys and frustrates me that I have to work around the software like that!
