Hi,
I'm been following some of the posts here and on some other forums and groups. Recently Neil posted an adjustment curve for Harman paper for B&W printing (using RGB file mode) and in another forum a user Matt S shared a profile he made for Harman that he tweaked for B&W output and called it extended gray.
I'm not exactly a printing novice, but have never delved into building profiles for myself. I'm just curious in general how much gain can be had by optimizing profiles for each paper/printer combo for B&W and Color output. I know Colorbyte does this for their Imageprint software but I don't see this elsewhere typically. Is there enough improvement to do this or will a really good color profile work fine in most cases?
Thanks,
Eric

Profile editors exist, so if you think you can enhance an existing ICC profile by tweaking it for B&W prints to get for example better shadow detail then there are tools to do that.
Possibly a step further is the B&W adaption of a profile made in Print Fix Pro II where extra patches are measured to get better neutrality in the recycled profile. At least that is what I understood of the process some time ago.
Then there is the profile creator of the QuadTone Rip that builds a semi-ICC profile based on B&W printed targets, the profile is only usable for B&W printing. It can be used outside a QTR workflow like Steve Kale has done with PS + the ABW mode of the Epson K3 printers.
With B&W modes in printer drivers the amount of color ink in the print is more reduced than in the color modes (less or no composite grey), the Dmax often is a bit higher too. So one should check whether using "B&W" profiles + the color mode of the driver is delivering the best Dmax + neutrality in time. The last both in printer consistency and in light resistance. That's why I tried to use QTR profiling in B&W modes of drivers or QTR itself.
