Demo : Acrylic Illustration Board
So this is a kind of standard illustration board, and to my mind, and these are very similar, they say that this is called pressed and this is rough, but the difference is so minor that I don't think you'd be able to tell even with the feel of it. It doesn't feel different to me. Alright, so I'm gonna test, I'm gonna grab a new brush, I'm gonna try using one of these round tipped brushes, which'll give a big, fat, round mark. You'd make like a circular shape with it, and just see how this feels. I'm gonna use some matte medium, and I'm gonna go test that green again. And again, mostly what you're seeing, the streak, is the streak of the paint itself, it's not really the surface. So what you're really exemplifying is what that brush is doing. So the brush gets to have a field day, and I'm gonna add, where's my white? Where did that go? Oh there it is, titanium white, I just want you to see. So it's really, it's a nice surface because again, it's slick, it's smooth, it's like a counterto...
p, so it's really quite pleasing, and it's still pretty wet, so I can blend into that in a way that it has some movement, it acts like oils, it's drying really fast. So because I used it in a little more impasto way, I can blend this while it's drying. I could use a little retardant, and that will slow down that drying time just a little bit more. But you can see, it's really nice, you can still mottle stuff on this surface because it is slick and because I'm using it thickly. So that's how you could see that, acrylics start to look a little bit like oil paints, it's still wet, it's still wet up here, so I can still mix this and blend it, and it's really quite lovely. And the retardant is helping to slow that dry time down. Again, this is a illustration board, it's smooth, and it's pretty similar to this. This is called rough, but I don't really feel much of a difference here. Let me throw some red. It moves very smoothly across the surface, and I'm keeping it much more thick, if I go thin, it acts more like watercolor paper, it's getting neutralize the red, look at how the red gets neutralized because green is mixing with it, and that's just because I didn't wash my brush very thoroughly. But that's okay because I kind of what you to see what happens when you neutralize the color. A red and a green are opposites in the color wheel, they make gray when they're combined. Now if I thin it out even further, again it starts to feel more like watercolor. It's a very smooth surface, what you're really seeing here is the stroke, the streak, look at how much green is in here, of the brush. So these are nice surfaces, you don't have to gesso them, the only reason why you would gesso them is if you love that streak that happened, that I showed you, it looks like wood grain. If you like that, you should gesso a surface of a board, but make sure you X the back of it.
