You do not need them for a digital negative. It is just that everone has

You vary the exposures and the pigments to achieve what you want. But then I
prefer to have most of my exposures at the minute or couple of minute.mark

Three and a half hours, do you mean three and a half minutes? If you can
achieve 2 minute exposures that harden the gum properly your UV light source
must be extremely bright compared to mine or your negatives are extremely
thin.

At the risk of being called pompous, there is a full explanation on my web

I've just looked at your web site and I see nothing there that explains how
to make or print digital negatives for gum, not even close.
