QTR for r1900

[Curt]

Can anyone tell me if I will need a QTR for my soon to arrive Epson r1900 printer?

Is this the QTR that is spoken about when people mention RIP's. I did see that the r1900 is listed on their page of printers. I've yet to figure out if it is a standalone program or if it is used by PS or an Epson driver.

I believe from what I have read that I can print a digital negative directly from the printer using all of the inks. If this is true what would be a starting setup for the printer, for those who know or have the r1900.

Thank you,
Curt

Yes QTR or quadtonerip is the software regularly referred to here for creating digital negatives. It is one of several methods for calibrating digital negatives along with Chartthrob, PDN, ect.

I use it as a standalone software, but I believe it can be used as a print driver. Others can chime in on that.

Yes, it allows you pretty complete control of all the various colors of ink. So for example, you can specify which color inks and their individual densities that will represent a middle grey in the image you are printing. In my case, for my cyanotype curve, middle grey will print a little density from matt black & yellow and more density from lt magenta, lt cyan and lt black.

It has a significant learning curve to get the hang of it. As you need to make an actual print from your revised curve to see it's effect. If you have a UV densitometer you can see the effects of your changes more quickly.

Go to Ron Reeders website for his most excellent tutorials on creating digital negatives with QTR and lots of curves you can download.

Rob, thanks for the info, I'll go to Ron Reeders site and read up, I needed to be pointed in the right direction, and your help is greatly appreciated.

I print digital negatives on an R1800. The R1900 has an updated ink set
(orange instead of blue) but may provide similar results. For the R1800 the simplest path to high quality negatives is just to print using all inks using a correction curve. The curve is easy to create if you have a reflection densitometer that can directly enter readings into a spreadsheet program like Excel. I use Inkpress, Arista, or Pictorico OHP; high-speed off; photo RPM (2880); premium glossy photo paper media; no gloss optimizer; icm with no color adjustment. These negatives may be even better than the ones I get from my 3800 (either QTR or colorized negatives).
