QTR-Quadtone RIP

Hi

Further to my problem with QTR, The Epson 2000P printer and the lack 
of curves, I have been experimenting today and I have found that I 
can use QTR with my 2000P and get a good print.

I simply treated the image as usual in Photoshop to get the best on 
screen representation of the scene, as if editing for a Photoshop 
print, then I converted it to greyscale, then I went to Image > 
Adjustments > Curves. Then I clicked on the curve line and put the 
following values into the Input / Output boxes as follows:

Input              63

Output           128

This gave me a pale image on screen with blown out highlights. I 
then saved this curve for future use. Your values may be a bit 
different depending on your printer characteristis but it will do as 
a trial and you can adjust the Input / Output values to your taste. 
I then saved the image. I opened QTR and loaded the image. I chose 
the Printer as Epson 2000P, set Printer Model to Quad 2000, chose 
Resolution 1440 Super, chose Speed – better, and pressed print.

The image produced was free of casts and metamerism, but was not as 
fine as an image produced by Photoshop in that the printer dots were 
more noticable under a magnifier, were much like the grain one gets 
with film and a wet print, but were not visible to the naked eye. It 
seems that QTR was only using the black ink. 

I am amazed that this simple method was not known by the other group 
members. I dont see why this method will not work with other 
printers for which profiles are not included in the Rip download.

Best Wishes,
John
