> Dear all,
> I'm finishing my section on gum thicknesses, and was wondering a question or
> two of all one-time to inveterate gum printers:
> 1. How many of you are using premixed gum?
> 2. If not and you are mixing your own, what dilution are you mixing it at
> exactly--weight of gum into what volume of water, for instance? If it is
> 300g in a TOTAL volume of 1 liter, or 300g PLUS one liter please
> differentiate clearly. If, mixing more than one solution, also state. If
> not using gum/pigment 1:1 sensitizer at time of use please note.
> Any other practices, I'd love to hear--e.g. using a hydrometer or some such
> thing. Or if you use dry gum at time of use in your sensitized mix and do
> not premix a gum solution. Stuff like that. I've got the timeline almost
> finished on gum dilutions from beginning til now and I want the "now" as in
> 2007. Hopefully this isn't too pointless, misleading, and confusing!
