This is the first time I printed a black and white photo with the canon pro 1.
I used the print studio pro 1.4 from Lightroom to print the black and white imagine.
The black and white image came out of nik silver efex.

When printing with print studio pro 1.4, I choose the icc profile of the 3rd part paper( canson baryta) for the printer.

The final imagine from the printer has a greenish cast and is not true neutral grey.

Anyone know what is wrong?
