Thank you. I will revisit ink choices if and when I have eliminated banding with OEM.

Sepia shade #4 is iffy on gloss overprint - but I did see excellent full glossy Sepia prints from Mark Savoie's shop last weekend. He uses a full Sepia setup. But, he sprays. > > All of the matte Piezography inks in shades 5-7 are compatible with gloss - we just don't publish that.

You simply overprint the entire sheet. We make GO curves to help in that but you do want to run that as a second printing to perfectly eliminate any gloss differential between the inks and between the inks and the paper. > > > Jon > > > > --- In QuadtoneRIP@yahoogroups.com, "shileshjani" <shileshjani@> wrote: > > > > Jon, > > > > The reason I have not tried Cone inks is that I want my LK and LLK inks to be a brown-warm color AND glossy compatible. Essentially, that is your "sepia" ink, which is not glossy compatible. I have rethought the need of this brown-warm color, especially when I created QTR curves on my OEM 4880. So for my 4800 (3rd party from the other ink manufacturer), I may have to start from scratch by putting back the OEM inks. I will do a full clean flush first, to remove any vestiges of the 3rd party inks. Check for alignment, and if it can be restored, I might think again of alternative 3rd party inks. > > > > My problem may be that some ink positions are incompatible chemically. The inks I have loaded are OEM PK, and the rest are 3rd party MK, LK, LLK, LM, LC, Blue (R1800 compatible), and GLOP. I am not sure if it is the OEM PK or the Blue that is causing incompatibilities. What I have noticed is that the flushing box does not drain fluid as fast as my OEM 4880. Hence my suspicion of incompatibility. But the capping station drains fluid just fine. So I am not sure what is going on. The 3rd party ink manufacturer assures me that their inks are compatible. This issue has now occurred on two 4XXX printers. > > > > Shilesh > > > > > > > > > > --- In QuadtoneRIP@yahoogroups.com, "piezobw" <jon@> wrote: > > > > > > Shilesh, > > > > > > Why would you abandon 3rd party inks? > > > > > > Both my Piezography and ConeColor are encapsulated like Epson and HP - a major achievement for a 3rd party ink.

The 4880 came about because she wanted a quick color print of our daughter, and I told her to go to Costco. Not a smart move on my part, but I had no color inks loaded in any of my printers. So I got the 4880 for my birthday present, I dare not muck it up with anything other than OEM color. I finally sat down last week and wrote up a few b/w QTR curves for it because my customary b/w 4800 is suffering banding. > > > > > > > > I am almost to a point of abandoning 3rd party inks - but I am keeping up about the possibility of glossy compatible Piezo Sepia. > > > > > > > > Shilesh > > > > > > > > --- In QuadtoneRIP@yahoogroups.com, "piezobw" <jon@> wrote: > > > > > > > > > > Geez Shilesh, > > > > > > > > > > You have to form an ink business or something so you can justify the madness to her.

So I can imagine the WF1100 may also be drivable with QTR, although I don't know how the dual K would be managed. Even if one of the K channels remain inactive, the printer should make a great quad printer. > > > > > > > > > > > > If you have one, try it. And let us know how it works out. Perhaps someone can appeal to Paul Roark because I know he has played around with it. Or, I could run over to Best Buy and pick one up for cheap. Grr, I can imagine my wife's reaction. I have a 4000, 4800, 4880, R2400, R220 all sitting around my office or closets. > > > > > > > > > > > > Shilesh > > > > > > > > > > > > > > > > > > --- In QuadtoneRIP@yahoogroups.com, "piezobw" <jon@> wrote: > > > > > > > > > > > > > > answers below: > > > > > > > > > > > > > > > > > > > > > --- In QuadtoneRIP@yahoogroups.com, "shileshjani" <shileshjani@> wrote: > > > > > > > > > > > > > > > > Two questions: > > > > > > > > > > > > > > > > (1) Can you select/address MK and PK channels independently, like on a 4000?

I can do this on the K3 printers with GLOP in the Yellow position. This is not the most ideal situation, but at least a fully controllable ink channel is not lost to GLOP. And it may not be possible to dial-in the most ideal ink limit for GLOP overcoat. > > > > > > > > > > > > > > One would need to find the exact RGB value that ONLY triggers Gloss Overprint. This would be easy in StudioPrint. Might be a study in PS to make sure it does not send any other inks which would stain the GO. However, one would also need to find the value that triggers about 33% of the GO which is close to ideal, rather than more or less. > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > This is a classic example of inquisitive users making tremendous contributions. Just imagine, are many people out there with 7900/9900 printers AND QTR, yet they never just tried the combination to see what would happen.
