Hello,
I am experiencing a new problem on an epson 1400 loaded with black mis eboni (recent batch) on arches, bo printing with qtr and Paul's profile.
I am having bleeding problems in the very deep black areas. (inside the prints with dark/light strong transitions and at the edges of the print)
This is what I tried :
head realignment : no effect
lower black boost at 70, 65: a little less problematic but problem not solved
with black level at 45 and no black boost the problem is nearly gone but still a little present with deep blacks ... of course the print looks flat like this.
Print on hpr and canson rag photographique : no problem at all.
One would advice to switch to coated papers but the fact is I like Arches a lot.
What could the problem be ?
printer problem?
batch of paper problem ?
ink problem ? (may be a STS batch ? bought in June this year)
Thanks

A scan (360 ppi) of a Calibration Mode QTR print on Arches is posted here:
All sharpening was turned off, exposure was on auto, and no modifications were made in Photoshop.
This "eb6" was mixed by me from STS WJ1082, which STS claims is the same as it was when Image Specialists was supplying the input MK for Eboni inks. I mixed the "eb6" dilutions with my C6c generic base.
Note that the dmax on the Calibration Mode print was 1.58. When printed vertically on Arches, it jumped to 1.68. With 2 positions of black, it jumps to 1.75.
I have no idea what MIS's current Eboni products are composed of. I know they were testing the new STS inputs. The reason I bought the STS wj1082 was that my last batch of MIS Eboni did not print the way the older Eboni-6 used to print a year ago. I have no idea why. I have now purchased two different lot numbers of STS wj1082, and they are essentially identical. So, what evidence I have suggests that STS is very capable of producing consistent inks.
Hope this helps.
Paul
