QTR-Quadtone RIP

Hi Alan,

I'm not expert enough to give you a definitive answer, but as another 
Lyson user I thought I would add my little bit. I don't often see 
the "L-word" mentioned in this group!

I am using the Lyson Quad Black neutral, not the Small Gamut set and 
I believe they will be very different in QTR. I was having problems 
getting decent prints with the QB set until I discovered QTR - now I 
can print on glossy paper and easily achieve a Dmax greater than 2 
without losing shadow detail. Even on matt (fine art) paper I can get 
a really good black, so I'm very pleased with the Lyson ink set now.

It seems to me though that the SG set will be completely different in 
that you only have one true "grey" - that is the black ink. To keep 
the tone (chromaticity) consistent across the full density range you 
would have to use at least one of the "grey" inks at all densities. 
As I understand QTR this would only happen if you called the grey ink 
a "toner". Or am I missing the point?

I was considering changing to the SG set before QTR solved my 
problems with the QB, and then I was struggling to see how QTR would 
handle the SG. I guessed that you would have to generate three 
separate curves, one for each "toner" and then combine then in 
different proportions at the print stage to get the tone you want. 
Can one of the real experts help? I would still like to try the SG 
set if it can compete with my Quad Black.

I opened the software, I was prompted to select a printer. I have two 
connected so naturally I opted for the one on my system for B&W. This 
in itself caused a program error which persists - access code 
violation. I guessed this was due to the use of the & (ampersand?) in 
the printer name. I've since renamed it but the error persists in 
slightly different form.

Paper combo. I felt this was not a critical step so I chose K6.
> After your earlier reply the penny dropped slightly so I selected 
the inkseparation6.tiff from the bin folder. This is the correct ink 
set up for my printer. I loaded this into the RIP under the current 
printer Model but when I selected Calibration Mode several things 
happened: Firstly, after initiating the several .exes quadtoprinter; 
Rawprint etc, the program returned a simple error message: I/O error. 
Although it continued to print - the software simply defaulted to 
printing the calibration test sheet for the model loaded - in this 
case the K6 ink set - which as stated has eight ink channels. I don't 
think this is useful because even if I disregard the two unused 
channels, last night's print out shows just the black ink channel 
reaches its limit at 30%. This is not true for the other five inks.

overwriting this installation and resetting my starting point (I 
cannot discover how to actually reload a 'new' printer model. I seem 
to be stuck with this erroneous first choice).

attached but it does seem to be slightly less than completely user 
friendly. Trust me - I've read everything twice by now :0)
