I am sure there are postings and discussions on how to use the spyder3 print here, but the search engine here is not so good.
Can you pint me to some threads?
I seem to remember someone from datacolor answered here a while ago.
I also wonder if the target I printed is valid if I just printed it from the software, as I did not first download the genericRGB.zip from datacolor and put it instead of the Epson PLP in the devices dialogue in the MBP. (to make a 0 transform trick) (as shown on youtube http://youtu.be/yALLJM3wu2U
) I just used the PLP paper profile without modification
added: maybe I should have posted this in the color management folder
