DTP70 Question - White or Black Backer Surface?

Anyone out there have experience with this? I’ve dug through all the X-rite docs but can’t find an answers as to why/when you’d use the white vs. black strip on the backer tray? My intended use is inkjet & digitial press profiling.

Thanks for any help!

The balck surface is intended for making measurements on papers that might have inking on the opposing side.

Professionals tend to use the white backing.

I recommend you use the white backing.

I’ll agree with that…here’s a link to a PDF with some more info on backing:

Thanks guys - that’s what I thought but wanted some confirmation.
