Digital BW, The Print

Cleavis,

Interesting idea.

I've rubbed black patches with my finger and measured the dmax drop to test
the effectiveness of a light fixative spray.  However, I suspect that a
change in the reflectance of light at an obtuse angle occurs well before one
could measure the rub-off with the densitometers we typically use.

I'll be interested to see what you find.

Subject: [Digital BW] How to set-up an abrasion test?


  I'm not much of a scientist, at least in developing a procedure.

  How to set up a theory and test parameters for abrasion resistance of
  inkjet prints, particularly as they would be applied in a book format?

  Ideas?

  Thanks,
  Cleavis
