QTR-Quadtone RIP

Hello,

I am looking for some guidance with using Museo Silver Rag in an Epson 1400 with MIS UT14 inks. I have searched the archives but have not found enough to help me. 

Does anyone have curves already developed for this combination? I have found them for IGFS. I decided to start with the IGFS curves and remove the linearity values, print step wedges and read with my densitometer to create new linearization values. The initial unlinearized prints do not have a very good dmax. I noticed that the ink limit is set to 32. 

Any help would be appreciated.

Scott

Scott,
    I made the Ilford GFS curves. It may well be that your paper requires more ink to reach its dmax.  The thing to do is to print the ink separation file using the QTR calibration mode to determine the appropriate ink limits for your paper and inks.  Take a look at the documentation that comes with QTR, especially the file Calibration.pdf in the Curve Design folder and the User Guide by Tom Moore, available on the QTR web site.

To be honest, the documentation is not as clear as it might be, and it took me a while to sort it all out.

Good luck,
David

David,

Thank you so much for the reply and the starting point with the IGFS curves. 

I think my biggest problems have been lack of experience with QTR and difficulty sorting through the documentation. 

After I posted the first message I did go back and print the calibration targets and found that MSR can take much more ink than I was giving it. I changed the ink limits in the MSR curves I had made and put in a black boost of 5. Then linearized.

Another mistake I was making (and I have no idea how I missed this) was that I was simply assigning "no" profile to my tiff files and then saving them with no embedded profile. After re-reading all of the notes and documentation I have found, I realized that I needed to convert to the QTR_Gray_Photo_Paper profile before saving. 

So clearly I had two major mistakes in my workflow. Not finding my ink limits and not prepping the file properly.

The prints that I made on MSR since fixing these two problems are quite nearly everything I was hoping for with this paper. Now I need to find a fix for these pizza wheel tracks.

Thank you again for the reply.
