Sorry I did not bring in the photo. Thanks Derek: I try the following setup: targen -v -d 2 -G -f420 -g128 Mitsubishi-PG printtarg -v -h -i CM -t360 -p A4 Mitsubishi-PG chartread -v -H -B Mitsubishi-PG colprof -v -qh -S sRGB.icm -cmt -dpp Mitsubishi-PG>out.log The result for L=39 is attached here. As you can see, it is similar to (but not the same) as the one I attached last time. BTW, my system is win7 32bits. Any suggestions are welcome. tmwu From: Derek Wells Sent: Saturday, April 09, 2011 4:34 PM To: argyllcms@xxxxxxxxxxxxx Subject: [argyllcms] Re: 2D view of icc's boundary is not smooth Hi Something I omitted from my first reply: you're producing targets optimised for the i1 Pro (which uses smaller patches), rather than the colormunki.
