I have this printed out and have read it but.... First, this is Mac centric. I'm on a PC. Second, he used ProfileMaker Pro using an EyeOne(?). I have the Spyder3Print spectro. Third, he talks of going into PS when you hit the print button. When I open QTR>Tools>Options>Calibration Mode, the Ink Pattern Page is shown. When I hit print, it prints the page and I'm assuming that since it is printing without PS running, it is not color managed. Since I printed through QTR(no PS involved) I printed out the pages as I previously outlined, so it answered my own question about whether a 3rd one was needed. Following into step 9 and doing the math, I multiplied the LK(25%) by the LLK(31%) which gave me .0775 for the LLK number. Does this sound low? In his second step 9 he says to use a text editor to open up the appropriate raw curve. This is where it looses me becuase it says that there are 4 raw curves from which to pick. Going into Program Files>QuadToneRip>Profiles>4800> I see three types of files. .amp, .raw, and .qidf. I see cool, coolse, sepia, warm. --- In QuadtoneRIP@yahoogroups.com, Michael King <drmrking@...> wrote: > > Keith, > > go off and read this and then if you have further questions come back and > ask... > > http://www.diallophotography.com/pdfs/QTRworkflow.pdf > > <http://www.diallophotography.com/pdfs/QTRworkflow.pdf>Mike > > On 14 September 2010 21:49, Keith <kjrslr@...> wrote: > > > > > > > Thanks Mike.
