Re: Gum calibration (was: Paper negatives- Ink Selection)

Hi Keith,

You can't tell by just looking - what counts is what the coating sees in
wavelengths it's sensitive to. Unfortunately, it can only help to see the
tonal distribution... Perhaps your inks are denser than mines in the UV
region, printed using the Tyvek paper profile. Have you tried plain paper
profile? Maybe it lays less ink compared to Tyvek?
