Thank you so much! I have always been looking for a "modified version" of lithography that is meant to be much easier to do than the traditional way. So I think maybe I can do the following: first, I take a SURFACE that absorbs water very well, then I paint, with OIL-based color, the NEGATIVE space, then, I apply water-based color all over the surface, so the surface absorbs the water-based color meanwhile the negative space does not hold the water-based color. If I put paper on the surface and press it, a print can be made. In your demonstration, "the surface that absorbs water" is the silk screen which is attached to the plastic plate, which makes sense. And I tried attaching an ordinary piece of cloth to a piece of plastic, it absorbs water equally well. You paint the negative space with white acrylic paint, but I found that acrylic paint still hold SOME water-based color (because acrylic itself is water-based) so the negative space in the print is not absolutely white. So I'm trying the real paint which is for FURNITURE on the negative space, and I'm waiting for it to dry right now, I hope it can make absolutely white negative space in the print.
Thanks for watching! This is an intaglio method where the ink is in the groves and that is printed onto paper. A water-based method, using water soluble ink. So using acrylics to build up the positive areas (lights/highlights) can resist the ink or can be wiped away is helpful to be painted in white. These acrylic based inks vary in porosity or sheen/ gloss making the printmaking ink easier to wipe or leaving plate tone. which you can experiment with. You can use water soluble printmaking inks such as Akua, Caligo, Charbonnel, etc instead of oil. Easier to clean up and better for your health.
