Created attachment 8404 [details] 30x42 blueprints The attached PDF renders correctly in Adobe Reader X, Foxit Reader 5.1, Okular 4.7.4, and Evince 3.2.1, but it doesn't render correctly using Ghostscript 8.4 (Windows) or Ghostscript 9.04 (Ubuntu Linux 11.10). (Sorry if you get this twice. It wasn't showing in "My Bugs" after my first submission.)
Created attachment 8409 [details] screenshot.png You are going to have be more specific as to what's incorrect in Ghostscript's output. The attached screenshot compares page 1 of your file displayed in Adobe Acrobat (left) vs page 1 converted to TIFF by Ghostscript 9.04 (right) and the two images appear identical to me.
