QTR-Quadtone RIP

Roy / Group –

Is high-speed enabled or disabled when we select <Unidirectional / 2880 dpi> for the R3000? I ask because the printer seems to print at high speed, especially compared to the Epson driver using comparable settings. With QTR I get banding top to bottom on regular glossy papers (e.g. Kirkland type) but no banding (and much slower printing) with the Epson driver, and print speed seems to be the cause.

Thanks,

Mark

Hi Sandy,

I already have Unidirectional/2880 dpi selected, but I don't see a <speed > option. I'm using the Windows interface, by the way.

I've looked at the Print Tool and its ‘speed’ options appear to be just Unidirectional or Bidirectional. I've only seen the Epson driver offer the option of high speed = off. That’s the option I'm looking for, and it doesn’t appear that QTR offers it. Maybe Roy can shed some light on this.

Thanks, Roy. The Epson driver offers high speed = off, in addition to unidirectional / bidirectional. That’s what I'd love to see in a future version of QTR. In the meantime, if you get a chance, please compare the print speeds on the R3000 (QTR versus Epson @ highest resolution, unidirectional) and I think you'll see Epson (with high speed off) is slower than QTR and smoother throughout (not just top / bottom). That’s what my test showed, but maybe I'm missing something.

Hi Sandy,

What I'm seeing is top to bottom fine horizontal banding but only when using thinner glossy papers. When I use Canson Platine, I don't see the banding, or perhaps it’s obscured by the paper’s texture. (So this limits my paper choice, obviously).

But what I'm *hearing* is the printer speeding back and forth even at unidirectional / 2880, which is what I'm curious about. When I print via the Epson driver, the printer slows to a crawl and there’s no banding on the thinner glossy papers.

By the way, I'm printing using a modified version of UT-14 inks, using all 8 channels for maximum smoothness. I'm very surprised to see any banding, even on the cheaper glossy paper.

Sandy,

I have a friend who has a 3000 and similar issues. Does the same thing happen with larger sheet sizes?

The result is that I consider the top and bottom 1.5" of a letter size page dead space and limit image size to a maximum height of about 8.5 inches. I have no understanding of the reason for this, but know that several other people who use QTR and the Epson R3000 have experienced it in printing digital negatives on letter size Pictrorico.
