I don't know if I 'need' to harden it, just would like to now how so I can try using harder ink in comparison to a softer ink in my learning stage. By what Jerevan said a matix soaked in warmer water will accept the softer ink better. (i could not get the harder 1803)
I think one of the problems here is that there are probably as many variables in the modus operandi of making Bromoils, as there are people making them. I have always found achieving low contrast bromoils more difficult than high contrast versions. I have posted one on the experimental media gallery made with soft lithographic ink.

straight out of the can without any stiffening.
Graphic Chemical product.
You can use magnesium carbonate to stiffen lithographic ink. A source for this would be Bostick & Sullivan: http://www.bostick-sullivan.com/cart...=search&page=1
I had the pleasure to meet Maija McDougal last year who gave a demonstration of the technique and some advice. She told me that most inks sold today are to soft and she uses beeswax to stiffen it. I tried Silverprint Bromoil ink and was given a jar of Maija's ink, the later was much better! But then I am no expert.
I read that, do you know in what ratios of Magnesium to Ink. I tried a 1:1of Magnesium Sulfate but didn't seem to effect it.

one can also use starch such as dextrine or pigment powder itself to harden the ink
