New to QTR and Creating curves, at a bit of a loss on where to continue.

2009-02-25 by mberkeypile

First off I'd like to thank you for reading this thread, and I ask
that you bear with me as I am quite new to QTR.

I followed the guidelines in the PDF explaining how to create a custom
curve to the following point:

I printed the 21x4-random greyscale step chart on a piece of my
desired media (Hahnemuhle Museum Etching).

I then moved the reference file for said chart to the EyeOne folder of
ProfileMaker, opened up MeasureTool, took a reading of the chart step
by step; and finally outputted the .txt file with all of the Lab
readings that I took.

From there I converted that txt into the graphed Lab values using
Drop-Quad-Profile.

This is the point at which I get very lost and confused.  The next
step in the process calls for a creation of the "ink description
file", with no truely informative instructions on doing so that I have
been able to find.  I tried copying one of the example ink
descriptions files from the examples folder and slightly modifying it,
but the results were very poor.

Firstly, the printer I am using is a Epson 2200, which has a 7 ink
set, but the most inks used on any of the examples was 6.  This I
suppose could be a factor.

Now, this next part is where I do something stupid, but with the
instructions I have, I didn't know what else to try.  After copying
the example ink description file and altering it to the best I could,
I created the curve, and printed the "Step-21-gray" file as suggested.
 I did not alter the "LINEARIZE" at the bottom of the ink description
file before making the curve.  The resulting print (from a greyscale
file) was a yellow --->green ---> blue ---> black step chart.

Being very confused, I figured that I was probably suppost to take the
LINEARIZE data from the first print I made and add it to the ink
description file that I created, then print and re-read to linearize.
 The result was even worse when I attempted this, with even more out
of whack colors (again, from a greyscale file!!!).





I know this has been incredibly long, perhaps confusing, and ignorant,
but I am at my wits end with this.  Any help you could give to me
would be absolutely appreciated to the fullest.

To further help analysis or steps to be taken:


Mac OS 10.4 Leopard - Epson 2200 inkjet printer using UltraChrome inks
- Hahnemuhle Museum Etching (a rag based paper with no optical
brighteners, 350gsm)

My apologies for not posting that before, and thanks again for even
reading this.
