Black and White Problem

Post by davidvj » Mon Apr 16, 2012 11:01 pm

HP b8850 with 8 cartridges including 3 black/grey. Printing from Digikam

With everything set for 'photo grey' the history of the last print indicates that TP is using only one black cartridge and all of the colour cartridges. The results are unsatisfactory. Can somebody reccommend a solution.

Thank you;

David

Hello,

please post the log file "/var/log/turboprint/print.log" - section of last print starting from "### New print job ..." is sufficient.

I have now changed the paper and profile to get perfect matches but still only 2 of the 3 black cartridges are working and the colour units are still being used. The log for the last print is below.

Only two of the 3 black inks are used at the same time - there is one grey ink plus two different black inks, one for glossy/semiglossy photo paper and one for matte paper.

A bit of color is added in dark areas to produce richer black.
