Thank you very much for your input. It is very much appreciated. I have also been through your website in my research. You use potassium oxalate, which at the moment I do not use and have no idea about, and as I am for the moment trying to keep things as simple as possible, maybe its better not to start on a new path for the moment.

I think I need to follow through with Sandy's instructions for the moment as he has explained things simply and in a way that makes sense to a novice like me.
There are a lot of things that I do not understant, and hope to find the answers to by communicating and reading all published material.
Things which are without doubt simple for all experienced in this technique, but certainly not obvious to me.
for example:

Difference between the K curve and the grey curve?

How to measure densities of the print as you mentioned. I have a color munki and it does allow me to measure the LAB values, but how does this translate to densities?

Why is the dmax on the transmission densometry of the steptablet negative low, but on the print (using the scanner), the blacks at 100% measure at 95% with the colourpicker in photoshop.

Alot to understand, and i really appreciate all the help that I get on this Group.
