Coincidentally, I received an unsolicited email via the blog today, and I'll quote some of the contents without naming the author, because it summarises my views and those of others that I speak to: "Unfortunately I find InkjetMall and the Piezography web sites to be a little difficult to digest. Information can be contradictory, incomplete, scattered or just not explained as fully as I would like. It does not help that it is an evolving process and often posts are written for a previous time, and may not apply today. I do wish the New manual was clearer, and I suspect I am not alone." No, that person is most definitely not alone. Which is precisely why I created the blog.
Getting back to the OP Andy's request for "a graph of L* values that would appear linear to a standard observer", my suggestion was to convert the standard 21x4 to an ICC generated by QTR-Create-ICC, print and measure. I suggested this because it remains my understanding that this was the science behind QTR-Create-ICC. Is there a better suggestion?

I suggest you download and read The New Piezography Manual. It’s the first place to look for Piezography workflow related stuff, and the documentation on this is there. Some things certainly need updating, but that will come in the 2016 edition.
