Partial analysis:
iSis more stable between measurements
iSis more stable between UV and non-UV
(However, two different spectros used with iO)
I will try to upload the screenshots to Derek site.
I can also upload the PatchTool Compare file; they can be opened with
PatchTool in demo mode, but the stats Tab is not available in demo.
Have to go to a meeting now, back later this afternoon.

Subject: Real world isis ver i1 iO test
I just posted measurement files from MY iSis and my iO table on my ftp
server.
I printed rgb 918 random chart with Gmg Colorproof 5.1 on Epson 9880.
Paper was Epson Standard Proofing Paper.
Charts used and ref files are also on ftp.
Explanation of naming.
2 charts were printed each for isis and io. Each chart was measured
twice with UV and twice with no UV filters.
P1m1 in the name means - print 1 measurement 1
P1m2 means print 1 measurement 2 and so on.
I waited 24 hrs before measurements.
Ftp server access:
Server/host: 72.248.216.20
User and password is colorsync
You can use ftp client or web browser:

Have fun and share your findings with me.
Derek
