Digital BW, The Print

Steve,

My understanding from several sources pertaining to color space conversions
is: If converting within a similar gamma space--Adobe RGB (1998) is a gamma
2.2 space--then, nothing (or very little) is to be lost. That said, it seems
that #6 is necessary based only on your printing workflow. For instance, is
using UT inks and Paul's curves, then, obviously, a conversion to grayscale
would not be necessary.

Subject: [Digital BW] Photokit Sharpener and B&W conrsion


I use Photokit Sharpener Pro for my sharpening (and highly recommend it).
But I have
one question.  My current workflow is broadly as follows for a colour
original - all 16
bit CS:

1. Open image and do a Capture Sharpen.  (If it is B&W then it Mode needs to
be
converted to RGB before one can use Photokit Sharpener.)

2.  Tidy and crop image, levels adjustments etc

3.  Convert to B&W using Split Channels (Gray Gamma 2.2 space).  Final
levels
adjustments, image size etc

4.  Mode to RGB.

5. Photokit output sharpen.

6.  Mode to grayscale.

7.  Print.

My question is, given all the discussion of refined methodologies for
converting to
B&W of which Split Channels is one method, whether there are any significant
issues
with respect to doing 4 to 6?  It is necessary in order to use Photokit.
