Thank you for everyone's inputs. I will continue working on this problem. -----Original Message----- From: Reeves, Tim R. [mailto:[log in to unmask]] Sent: Friday, October 08, 2004 7:45 AM To: [log in to unmask] Subject: Re: [TN] Registration problem Are the coupons scaled the same as the images? Are you sure? Is it a sequential lamination? If the drill is scaled (even from the center) it still has to be positioned relative to the innerlayer images correctly. How is this done? Are you using a drill optimizer (Smart Drill, Pluritec or the like)? If so, where are the optimizer targets?

Inside the panel, however, registration is good on the lower left corner but starts getting bad towards the right and top of the panel making it look like drill is scaled from the lower left corner. Drill operator confirms that drill is scaled from the center not the corner. I can't explain how this problem happened and would appreciate any help. Thank you in advance.
