Watercolor paper such as the Tombow watercolor pad is well suited for working with wet paints such as watercolor painting. There are various techniques for this. You can moisten the paper with water before actually painting. The colors can then be applied well and the firm paper still lies on the block without waves, even when wet, because it is glued to the block at two edges. You can also paint wet-on-dry by picking up the paint from the palette with a brush or water brush and painting it onto the dry paper. Or you can paint directly onto the dry watercolor paper with the ABT Dual Brush Pen and then blend the paint with a brush and water.
If you like to work a little more artistically with different media (mixed media), you can also print out designs that you have created on the computer with digital graphics programs, for example, on watercolor paper and then work on them with watercolors. It is important that you do not paint on the printed color, as water-based paint does not adhere to it, but complete the design on the free areas with watercolor paint.
