Dear Ethan, Thank you for taking the time to explain your technique. I think I got the idea and I shall give it a try. Best / Roger -----Original Message----- From: colorsync-users-bounces+graxx=videotron.ca@lists.apple.com [mailto:colorsync-users-bounces+graxx=videotron.ca@lists.apple.com] On Behalf Of Ethan Hansen Sent: May-02-12 1:16 PM To: 'colorsync-users List' Subject: RE: ColorPort Updated to 2.0.5 Roger, I got the new Colorport (Windows version - not brave enough to go through the hassle of using a Mac for this) working on a Spectroscan with old targets. I needed to create a new ColorPort target to do so. The key was rotating the patch set 90 degrees counter clockwise. I started with a MeasureTool format chart, did the rotation using ColorLab (Mirror, followed by Swap Rows/Columns), imported the patch set into ColorPort, and fiddled around with the paper size, margins, and patch size until the ColorPort version matched the real target. Even though ColorPort claims to support Landscape orientation , I could not get it to do so. I used a page size of 8.5 x 11.5 inches, no margins, portrait orientation. The chart I tested required the patch size be set to 6.25mm (nothing like mixing your units!). ColorPort measured away happily. The measurement quality, however, was useless. ColorPort only rarely re-calibrates the Spectrolino. Our charts have a number of repeated patches. MeasureTool shows each series of repeated patches agreeing within 0.05dE of each other. Measuring the same chart with ColorPort 2.05 showed the effects of thermal drift. The worst offender were two identical patches that ColorPort reported differed by 1.21 dE. A 40% increase in measurement speed does not justify a 25x increase in measurement error. Cheers, Ethan
