Yeah, I went through the color transformation instructions for some
time, and tried to hit a black point, but with no real luck. I do
pretty well when the image includes a white point.
There is a process for adjusting other colors, but it is complex, and I
had spent too much energy already. I saved it for another day.

Hi Moose,
I printed out your suggestions, and explored the Cross Pen image
again, using the tools in PWP. Needless to say, I have never read
many of the 583 pages of the PWP Manual. Once I got a better idea of
how the curves worked, I figured out how to use them and the
histograms in both the Brightness and Color Transformations. I
worked with those, and then tried your settings (as close as I could)
in the Sharpen Transformation.
I now have a basic knowledge of how these things work. You made my day.
Hooray!
I am attaching an image that resulted.
Ah, you really are gaining more control.
I will next look into the secret of getting a pure white background,
but that is rough because of the lighting mix that I had.
Shouldn't be too tough. The same light is on the pen, so an overall
color balance adjustment should do the job and make the pen color
truer, too. In the color section of the manual, pp125ff, I see several
tools to try. When I tried the PS tool similar to their "Color Probe"
(sounds painful), I got purple shadow. But theirs works differently,
what with choosing at what brightness it is strongest, as I read the
instructions. (The trio of "probes" in PS that gave me a nice clean
white background and nice, neutral shadows when I tried them just now
aren't in PWP.)
