Looking for a QTR profile for printing negatives for carbon transfer on an R1800

[John Lockhart]

I am getting ready to start printing carbon transfer and I wanted to now if anyone has a QTR profile for carbon transfer suited for the R1800. I have had good results with that printer using ChartThrob to produce curves for kallitypes. However, I want to start using a less destructive means to linearize the process.

If you have anything I could start with, I would greatly appreciate it and would be certain to share any modifications or useful results I produce.

Regards,

John,

1. You can input CharThrob curves into QTR. It's very easy to do. That way, you won't have to mess with adding a curve directly to your file.

2. If you have a palladium curve, start with that. You need a very contrasty negative for carbon. You'll also have access to all the usual carbon contrast controls, ie, pigment load, dichromate level, etc.

Thanks, I will give that a shot.

But remember that the CT curves are for positives (right? if I recall...) and you'll need to use a curve for the negative in QTR that reads in ink densities rather than the "0-255" curve we usually work with in PS.
