Re: [PPLetterpress] Re: relief inks that bronze
- hi Susan,Thanks for the description. I probably need to experiment some - I've never noticed this kind of problem, but I rarely print a large solid surface of black. No such effect on a woodtype poster I did in Van Son black for the recent APA large tube mailing (which has a good-sized black border ornament as well as solid black wood type letters), and I don't see anything like this on any of the other blacks using larger wood type and other images in that same APA mailing.Most black inks (excepting the Pantone Black for color mixing) do have blue pigment added - apparently to make it seem more opaque somehow. But that blue mostly shows when black is mixed to try to make a dark yellow (thus turning it green) or if it is mixed with a warm red (thus turning it a muddy purplish brown). I've never really noticed the blue in straight black ink, though I suppose color in the paper could affect it.For anything I do, I generally wouldn't print with such litho inks lacking dryers. I suspect the effects you describe may be a result of the paper surface as much as the ink itself? Does this Japanese paper have variations of fibers which might alter the absorption in different places? An ink that dries more by oxidation than absorption could be an answer.Best wishes,TomTom Parson/ Now It's Up To You

I print it flat black, laying it on the print racks to dry. As it dries it develops a kind of blue sheen to it, no longer looking black everywhere. Very annoying if you do not want that bluish color. The "spikiness" that I notice, or interpret as a blotchiness, that again, starts showing up after a few days drying.

Sorry but I just don't quite know what it means that an ink "bronzes" nor what a "weird spiking effect" might be. Technical language baffles me 96.2% of the time. Probably means something I've seen but I don't know what.best wishes,TomIn a message dated 10/1/2012 8:36:14 P.M. Mountain Daylight Time, smakov@... writes:Gerald,Thanks for your insights. Yes I have gotten that spiking you mention, though not what I wanted. Off to buy some new ink. Thanks.

Thinking about this some more I suspect the bronzing might simply be the effect of your mixing a relief ink with a matte litho ink. I once mixed Handschy Crayon Black (a stone litho ink) with good ole tried and true Van Son 10850 (which works in some applications) and got this weird spiking effect. Kind of liked it for the piece but probably could never replicate it no matter how I tried.

The Stiff Opaque White is to die for and the Laketine extender is bizarrely cool. Best line of inks I have found.

I am printing on Tosa Hanga Japanese paper. I air dry it (I live in a very arid area) because it seems to take at least a week to dry. Any additives or special relief inks that do not bronze? Thanks for your ideas.
