update. I have ink flowing through the magenta line that was giving me problems, but I'm not able to get a proper nozzle check. I also ran a Magenta Flush image file and it was successfully printing

... working through getting that line to clear on the print head now. Slow going, but getting there. However, I have all the carts filled as per @Paul Roark's glossy variable setting. Will start

Here is a copy and paste from the v3 instructions from my support

Dear Kim: Yes, I bought cartridges with autoreset chips and the necessary inks. Carefully prepared the mixtures, filled the cartridges, primed them and use them in the R2880. So far it seems to work.

Hi ! Please find attached an email conversation (as a PDF file) I recently had with Richard Boutwell about the latest version of his software. I think you'll find answers to your questions in this

Dear Henrik, And do you use that ink in your Espon R2880? Or in a different printer?

Criss Hartzell, When I switched to this method my linearization was very quick and when scanning the 51 step step-wedge with my i1 Pro I ended up exactly following the green line in the

Yes, this confused me too. I made several curves for Pd/Pt and carbon by changing the total ink load to correspond to my blocking density. They worked ok, but, I noticed I was getting star wheel marks

If anyone out there is using the newest version of QuadToneProfiler-QuickCurve DN (version 3.1.3) by Richard Boutwell? ? I am wondering exactly where you are supposed to enter the Blocking Density

I was facing the same situation. I am now using the GCVT monochrome ink set of Paul Roark and getting acquainted with QTR.

They don't sell the original ink for my Epson R2880 anymore. And I've checked the Epson website for printers that use UltraChrome ink, but they don't sell them anymore in The Netherlands. Does anyone

Follow up. Got the ink lines cleared. Magenta was blocked with some hard bits, cyan and yellow not so bad. All others cleaned initially with a power clean. Was able to bleed the troublesome lines

The important thing first: Please don't get me wrong. I appreciate and admire the work of Roy. I think his work has been groundbreaking making RIP accessible to people like me and others. I am

Just an observer here and I am not interested in understanding the math. But making pictures by any means is not a mathematical equation. Roy I personally appreciate the work you have done in

The ink transition could be very different. Although the density could be corrected in linearization, but transition (pre-linearization) defines the ink amount and the "grittiness" or "roughness" of

The trouble is that he's got it wrong. He shows how he interpreted it and it's just not correct and not what the PDF says. Please stop saying it's an "alternate" interpretation. Roy -- the

Ok so it was a space between the folder Quad P5000. Once I removed the space it worked. Thanks Walker and Roy.

This is kind of a PSA I guess. When I teach workshops in digital negatives and DTP processes using QuadToneRIP, many people get heartburn at the notion of spending anywhere from $300 to $3000 for a
