How do different reducers affect the erasing of Createx Illustration Colors? Ok, the results are in! The results were less exciting than I was expecting. Using a soft eraser, aggressive eraser, fiber pencil, and blade, there was barely a noticeable difference between the different reducers. I excluded 4020 because Createx states on their website, " The soft erasing trait time window is removed as 4020 will aggressively air cure Createx illustration colors." This experiment was done on Yupo synthetic paper so the blade test is poor. As Dru Blair says, "Yupo can't take the blade like Blair synthetic." The paint was a mixed bottle of a "buffered" color. All were done with a 50% reduction at 20 psi. The 4030 was done at 10% (as recommended by Createx) reduced 50% with 4012. The water & 4011 were slightly easier to erase than both the 4012 & the 4030 reduced with 4012. Createx claims that 4012 dries faster & cures with improved film properties. I would agree that soft erasing with the 4012 is more subtle because it doesn't erase as fast or easy as the water & 4011. And subtle is what you are trying to achieve with soft erasing. The 4012 takes more elbow grease to erase & is more forgiving. I learned a few other comparisons with this test other than how these different reducers erase. The paint reduced with water was much grainier than the rest. Since this test was done on non-porous synthetic paper this was more noticeable and I would think that it would be noticeable on other hard surfaces. The smoothest was the 4012. Results may differ using different reductions and/or psi. The 4030 did flow good but the test wasn't long enough to compare tip dry differences of each. The coverage of the 4030 wasn't as much as the rest even at the recommended 10% (as should be expected). As a result the 4030 was less uniform. Part of that could be user ability. And just for fun, I did a "homemade" reducer test using the Jason Jones recipe easily found online. It erased about the same as reducing with water and was even more grainy. I mean, bad. Pigment migration. In my opinion, save your money and use tap water. It will come out better. In a pinch I might would use it for Wicked since water cannot be used to reduce Wicked. This was a quick test and your results may vary. My conclusion is that Createx Illustration is great paint and will do great reduced with water, 4011, 4012 or no reduction at all at the right psi. I honestly don't think I could tell a difference between 4011 & 4012 unless I had them side by side. Don't take my word for it, I'm just another guy with an airbrush.
