HP Z3100 B&W Printing

[Richard Man]

Have anyone else have problems with printing B&W on glossy paper (e.g. Harman Al Gloss Fb)  on the Z3100? I calibrated the paper and have color profile of course, but the blacks are d not quite right. The only reference I found on the web is this from

We're not sure why this is the case, but when evaluating the grayscale ramp in the test image it was clear that the HP was definitely darker, and that while not blocked up, the darkest wedges showed less separation that did the same wedges on the Epson printer. This was also visible on the image of the woman and child, where her black leotard separates more clearly in the Epson rendition than it did on the HP's. We didn't have time to investigate this in detail, but I hope to return to this question at a future date.

I have finally made an adjustment curve on top of the ICC profile and the results look great (print a 21 step wedge then scan and measure). However, I am wondering whether I am the only one with the problem!

Comments and thoughts?

I have not used that paper but:

Make a custom media preset for the paper with the most suitable media preset as mentioned by either HP or Harman. Do not use the HP Baryta media preset, old or new one, as it is has flaws. Calibrate the media preset. Either use a custom ICC profile made on the Z3100 and use color mode + application CM-on or use the B&W mode + printer CM-on and a B&W image with 2.2 Gamma assigned.

Next step could be the B&W mode and a QTR created custom "ICC" B&W profile. Depending on the application you print from you have to adapt the conversion to that QTR printer profile.

For the HP Baryta media preset flaw:
