Yes, MeasureTool is capable of measuring the Standard IT8.7/4 Random target just fine. But it I am looking for a faster alternative than reading columns by columns. As it turns out, reading in columns mode takes a good 100 minutes to complete the task whereas reading the same target in row mode takes 55 minutes. You see the difference? I used to be able to read that target with ColorToolbox. But now, I get reading errors. Like the black patch in the center reads 19 0 1 but the black patch in the lower right hand corner reads 19 5 2? I suspect there is something wrong with the table electronics itself? But, oddly enough, MeasureTool gets the number right! Consistently. I tried basICColor Catch, which is a phenomenal application, but, once I get the position right for the three corners, the head then starts to read *between* rows? I have a message into basICColor to that effect but I don't think there is anything they'll be able to suggest. Yesterday afternoon, I managed to read the target, in row mode, using Kodak ProfileWizardMio v4. I have yet to compare the results, whether the target will read the same repeatedly. But the initial results are encouraging. I tried MonacoProfiler 4.8 too but it suffers from the same discrepancy as ColorPort: even though it reads the target row by row, starting from the upper left hand corner (never understood why?), yet the patches come in the wrong order, recorded column by column? I tried with an earlier version of Color Tools 3.0 but I got the same error. I have another used Spectroscan coming in. I am anxious to try it with this one. My next step is to try Argyll... Just have to figure out how to import the reference file in.

Hi Roger, Basiccolor Catch will read a IT8.7/4 Random test chart on an IO table, something I've never accomplished with ColorPort, and it supports the Spectroscan. Matt Louis
Hello everyone, basICColor catch works a bit different than other measurement xy-instruments. Other solutions are settings the dimensions of the chart by positioning the cross into the middle of a patch. But in basICColor catch the cross has to be set at the outer corner of the patch to define/calculate the size of the chart. If the cross is set to the middle of the patch basICColor catch will calculate the size of the chart wrong and it won't read out the chart correctly, because of the wrong size settings. ––––––––––––––– | | | X | Position of the cross in other apps | | –––––––|–––––– X –––––––––––– | | | | Position of the cross in basICColor catch | | –––––––|–––––– | | I hope this schematic graphic of the top left edge of a chart explains the difference of the position?!

Dear Tim, That was an important detail. And I tried it already and it arbeit gut! I must say I am very pleased with the way basICColor Catch drives the Spectroscan. To be able to read rows by rows instead of columns by columns cuts the measuring time in almost half. Why didn't GretagMacbeth thought of that way back 10 years ago, when they first introduce the instrument is beyond me? I noticed that Catch regularly recalibrates the Lino at every, oh!, 150 patches or so, avoiding the thermal drift issues noted by Ethan in ColorPort. Now, I did read the same IT8.7/4 target twice heute. And when I brought the measurements into BabelColor PatchTool for visual inspection, the first measurement file was not recognized as a standard IT8.7/4 Random test chart but the second measurement file was. PatchTool was then able to reorganize the patches according the standard Random format. I will give another try at the this target tomorrow but I think Catch is a solution for me.

Argyll has done it this way for a long time. Also hex layout charts, to pack more samples in a sheet. And optimised the recalibrates to happen at the end of the lines, minimizing the seeking. Graeme Gill.
