QTR-Quadtone RIP

Hi,

I bougth a set of Piezography Neutral K7  inks for the Epson R2400 and
a tried to print with the QTR.
I've choosen Hahnemuehle Photorag (bought in Germany) and the QTR
Settings as follows.

Printer: Epson R2400
Printer Type: QuadR2400-K7
Media Source: Manual Roll
Media Type: Matte
Resulution:2880 and 1440 (I tried both, with almost the same result)
Speed: Better
Dither:Ordered
Curve: K7-2880-HanPhotorag and K7-2880-HanPhotorag (Tried both with
the same results)
Ink Limit: 0
Gamma: 0


The result where poor, because the ink is bleeding on edges between
dark and light areas. I've checked the paper in the printer, but the
coated side was in the correct position. I have no glue, where this
"bleeding" comes from and how I can get rid of it. For me, It looks
like, that the printer/QTR puts much to much ink on the paper, because
the paper is totally soaked with ink and gets undulated. I also
reduced the Ink Limit to -15 with only minor changes in the result. 

Does anybody know, how to solve this problem?
Are there differences in the Hahnemuehle Paper between the US and
Germany which can affect the QTR-Profiles?


thanks and regards
Andreas

Hi Andreas,

Unfortunately I have no answer to your problem. It can't be the 
problem of using matte black on glossy paper since Photorag is matte. 

But what I CAN do is to confirm it will NOT be caused by local 
difference in the paper. I live in the Netherlands (so if there would 
be something like local differences I am getting the same stuff as 
you do) and have used Photorag with the pre-canned QTR curves (on my 
2100 with Epson OEM inks and MIS UT-3D inks) with no problem 
whatsoever.

One problem I had recently when I switched from Epson inks to the MIS 
inks was that one of my cartridges was leaking (or I spilled some 
ink?). After a few pages the problem was gone. Coudl you have the 
same problem?

I'm not sure if it is needed to use cleaning fluid when changing from 
Epson to NK7 (it's not between Epson and MIS, but would be necessery 
between Epson and e.g. Lyson).

Good luck,

Joost

are you sure you are printing on the coated side of the paper?
Worth checking...

I had the same problem when I installed my first set of K-& inks n my 2400. The bleeding was especially bad on the margins of the page. I solved the problem by taking out the cartridges and putting them back in. I think the problem may have been caused by a bad seal. They work fine now.

Hi did you ever get this fixed? I just installed K7 on an Epson 7600 - printing on HPR.. I 
am seeing very pronounced  bleeding of the greater than 95% blocks!!
