Thanks for producing these tutorial videos chaps, I'm really getting a lot out of the new C2PS tutorial and it has prompted me to look back at the LR3 tutorials to fill in some blanks I had forgotten about.
One area where the new tutorial differs from the LR3 tutorial is when using the Epson advanced black & white section of the printer driver. The LR3 tutorial "Lr3_31_print2.mov" talks about purposely doing double colour management by setting the LR Print Job colour management profile to Adobe RGB 1998, and in the Page Setup (printer driver dialog) selecting Advanced B&W, the reason given was that the Epson driver acts a bit like a RIP and expects the data to be sent to it in Adobe RGB 1998.
In the new C2PS_38_IP-EpsonAdvB&W.mov, the recommendation is to set the LR Print Job colour management to "Managed by Printer" and (as before) in the Page Setup (printer driver dialog) selecting Advanced B&W.
What is the reason for the changed recommendation? Has the Epson Advanced B&W "driver" changed a lot or something?
