The white box is showing what the art board size is when I open the PDF in illustrator (To edit). Yet when I go to place the PDF in a new document, the size changes. It is not saving he white/blank space on the art board, and just saving it to the art that's in the file. It's an illustrator setting, because when I open it in acrobat, it shows the white space included.
My last step in pre flight is throwing it in a new doc to make sure the sizing is correct, and there's no hidden layers that show up for print.
The obvious solution is to just add a white box in my art file, but I would like to know a fix that doesn't include that.
