Scum+Dot

=I am getting large areas outside the image that are slightly darker than paper white=


 * Problem:** I have a complete print with large slightly darker area outside the image (size of darker margin varies according to image cell size settings in Lightroom). My picture prints complete.The darker margins are only on the top and sides of the picture; which in this case are the left and right margins in Lightroom (since the print is rotated by Lightroom to fit in the page). The prroblem is described in this [|Discussion Forum thread] and shown below (enhanced in Photoshop to be easily visible):




 * Description:** This is the so-called "scum dot" problem. [|Scum dot] is an offset printing term where you have a small amount of ink that differentiates it from paper white. Possible causes:
 * Using Version 4 profiles on Mac OS X, as discussed at length in[| this Luminous Landscape thread]
 * Problem occurs with [|some profilemaking software], not with others. Occasionally seen with version 2 profiles.
 * Printer is a a different state of calibration than when the profile was made (especially likely to be a problem for third party paper profiles if either their printer or yours wasn't calibrated)
 * Media Type setting doesn't match the Media Type used when the profile was made


 * Resolution:** A custom profile with printer calibrated and using the same media type as when the profile was made solved the problem.
