barograph ink

I can't find composition for this ink but would buy some cheap fountain pen ink and try adding things to it to slow down drying. I even saw some mention of adding honey to the ink.* There are also water soluble solvents like diethylene glycol that
might work to slow down rate of evaporation.

Price of inkjet printer ink annoys us.* You used to be able to re-ink cartridges but now with HP and maybe others that will not work.

Reminds me decades ago of researchers at Kodak telling me that they sold their cameras at cost but made huge profits from their films.

They spend a fortune to design a 35mm film cartidge that couldnt' be
opened and reclosed without damaging it.

Now the printer makers are doing it, selling printers at no profit to make it up on ink.

They've been doing that for a long time. Or at least they've been making
it hard to refill cartridges or use aftermarket. Maybe they stepped up
their game recently??


I'm surprised Harbor Freight doesn't have a line of Chicago Electric inkjet printers with 1 gallon ink refills for $29.95.
