Re: Conversion to Greyscale Methods

2005-04-04 by ferdinand_paris

As Stephen Kale said, what you use as your method of conversion to B&W
will not matter to QTR.  You need to use the method of conversion that
gives you the monochrome image that you want.  

Likewise, it matters not whether or not you use the "QTR-Gray Lab"
space as your working space when you edit the image.

What matters to QTR is the space you convert the image to before
sending the image to QTR for printing.  You should use "QTR - Gray
Matte Paper" (or "QTR - Gray Photo Paper").

What I'd like is a clearer explanation of the steps that Petteri
Sulonen is using in his "printing" phase:
 
http://194.100.88.243/petteri/pont/How_to/n_Digital_BW/a_Digital_Black_and_White.html?page=4

He doesn't explain the purpose of each of the layers.  I assume that
the tint layer is fairly useless if you're going to print using QTR.
