The bottom 20% and top 20% are filled rectangles that goes from edge to edge with text , so the banding was noticeable. The center portion is a lion's head & mane that merges into the bottom part with text in the middle. <hr /><a name="a5808_19"></a><p><b>From: Harvey only (HARVEY-ONLY)</b> [<a href="lmessages.php?webtag=EE&msg=5808.19">#19</a>]<br /> 22 Jan 2007<br /><b>To: Awardsguy</b> [<a href="lmessages.php?webtag=EE&msg=5808.18">#18</a>] 28 Jan 2007</p> <p>The answer appears.</p> <p>The dithering in the filled rectangles is conflicting with the DPI of the laser. Convert those to bitmap at an even multiple of the laser's DPI and it is solved.</p> <hr /><a name="a5808_20"></a><p><b>From: Awardsguy</b> [<a href="lmessages.php?webtag=EE&msg=5808.20">#20</a>]<br /> 28 Jan 2007<br /><b>To: Harvey only (HARVEY-ONLY)</b> [<a href="lmessages.php?webtag=EE&msg=5808.19">#19</a>] 28 Jan 2007</p> <p>Thanks Harvey, I will give that a try.</p> <p>As you know I had a problem getting to the EE site. I thought I'd try another computer. Haven't had time to try the fix from Computer Associates on the other 2 and I'm a little gun-shy about using my work computers until I've done all of the diagnostics.</p> <p>I appreciate your help with everything.</p> <hr /><p align="center">Show messages: <a href="lmessages.php?webtag=EE&msg=5808.1">All</a>  <a href="lmessages.php?webtag=EE&msg=5808.1">1-16</a>  17-20</p> <h4><a href="lthread_list.php?webtag=EE">Back to thread list</a> | <a href="llogout.php?webtag=EE">Login</a></h4> <h6>© 2025 <a href="http://www.beehiveforum.net/" target="_blank">Project Beehive Forum</a></h6> </body>
