Edmund, I believe that you are looking for documentation from ISO 5 which defines the standards for calculating density. A simple introduction can be found at http://www.rps-isg.org/DF2008/ISO5Densitometry.pdf.

Two questions: - How do I convert spectro readings to something useful eg. density measurements?
ColorPort is really good for this.
Maybe you could explain some because when I read a wedge via Colorport all I see in the file is spectral measurements: BEGIN_DATA_FORMAT SampleID SAMPLE_NAME CMYK_C CMYK_M CMYK_Y CMYK_K LAB_L LAB_A LAB_B nm400 nm410 nm420 nm430 nm440 nm450 nm460 nm470 nm480 nm490 nm500 nm510 nm520 nm530 nm540 nm550 nm560 nm570 nm580 nm590 nm600 nm610 nm620 nm630 nm640 nm650 nm660 nm670 nm680 nm690 nm700 END_DATA_FORMAT
Is there software that spits out a file of such from a CGATS file eg. from i1 or DTP70?
Scripting can be used for this.
- How do I derive a good linearisation distribution from said measurements?
Have you used the "QTR-Linearize-Data.app" app? Fantastic stuff.
