I have an i1 spectro and use EyeOne Match to make printer profiles. I often see discussions of d-max in reference to max black density. How do you perform this measurement? Can I use EyeOne Match to do this, or do I need some other software?
Use Eye-One Share, available for download from X-Rite/GM's site. This will give you an L* value which you can plug into Bruce Lindbloom's online calculator:
