Viscosity Color Etching with Akua Inks, anyone??

I'm a new member and hope someone out there can help me out. Iím a printmaker whoís been doing viscosity color etching for many years, I print multiple colors of ink from a single plate rather than relying upon multiple plates for color separation. I use 2 different durometer of soft and hard rollers for the roll ups. I've discovered Akua Inks recently and am very excited about its potentials. Has anyone pursued viscosity color etching using Akua inks and their modifiers? I also have Aqua Wash by Charbonnel which I hope to incorporate. Hope to hear from some of you, printmakers! Thanks!!

Re: Viscosity Color Etching with Akua Inks, anyone??

I have briefly tried the Akua intaglio inks and didn't like it at all. Too low viscosity and very easy to mess up everything because of the low viscosity. Those inks seem to work well for many printmakers, but personally I like more stiff inks. I probably have so strong touch when wiping the plates that I'm not able to control such fluid inks.

Charbonnel Aqua Wash is good stuff and I use it as my everyday ink. I really love the fact that they have large number of black inks that are really different, so there is something for every purpose. For viscosity printing you may need also their Aqua Wash oil and some magnesium carbonate powder to reduce or increase the ink viscosity, since the ink viscosity varies a lot between different colors. I use only blacks and sometimes their process colors, and the colors are much lower viscosity than the blacks.

In viscosity printing there might be fundamental problems when mixing those two, since you would have to print the stiff Aqua Wash first and then the fluid Akua, but Akua inks dry by absorption (solvent is drawn off to the paper fibres) and any Aqua Wash ink layer might prevent it from happening. It might work, but my gut feeling says that it won't work. The opposite order would work, i.e. print Akua first and then Aqua wash, but it would require heavy usage of modifiers.

Re: Viscosity Color Etching with Akua Inks, anyone??

I appreciate your quick feedback and idea. Although I liked Charbonnel Aqua Wash, it would take a lot of ink to rolli up with 18Ē rollers. So, I used it for simple straight forward printing. I didnít even attempt to do viscosity etching with CAW. Itís rather an expensive way to experiment as those inks are not cheap.

I have yet to experiment with Akua intaglio inks and its modifiers. Iíll first try to alter the viscosities of the inks. The transparent base and magnesium carbonate powder are supposed to make the ink tacky, while mixing with the blending medium would make it runny. Subsequently, Iíll roll up these inks with my rollers over the wiped intaglio plate. I donít know whether this would work successfully or even work at all. I'll have to just try them out.

If anyone has tried and done viscosity printing, I would appreciate your insights as well as problems you encountered.
