I'm sorry but I am off to catch a flight to Moscow so this is rushed. (I
also need to catch up on the Colorburst posts.) In essence, you scan a step
wedge with MeasureTool or like software. Then feed the data by dragging and
dropping the MT output file onto the QTR Create ICC applet and it generates
an ICC profile. Full colour information is stored in the tags used for soft
proofing but only luminance data is stored in the tags managing the outbound
leg to the printer. Hence you get luminance scaling for whitepoint and
blackpoint on the outbound and full colour soft proofing. So you can
profile any B&W print flow. For example, let's say you want to print a warm
toned print with Epson Adv B&W. You print a target with the tint settings
you like (I leave all the luminance oriented settings at their default),
measure the target and create a profile for those settings. You can then
soft proof your image for those tint settings. You'll also get proper
management of the luminance differences between the file colour space and
the output of the Adv B&W driver with those settings. An added benefit is
that if you want to display your image on the web with those exact same hues
then you can simply convert the file to that ICC profile and voila the image
on screen looks the same as the image in print (black and white points
adjusted).

The RIP itself is fantastic for B&W work - complete and individual control
over most Epson printers. And all for a mere $50.
