(vi) Repellency This refers to a repulsive force of water. Oil is
repelled where there are water paintings, and water is repelled where there
are oil painting. Offset printing uses the repellency of water and oil.
Here the creation of various accident patterns will be tried utilizing
this nature. When we consider that all colors belong to either water-based
materials or oil-based materials, we discover there are many kinds. As
for oil-based paints, there are crayon, pastel, and so on including the
oil colors. Though colors are not included, the wax of a candle and others
is useful for pattern- making of repellency, also. Water-based paints include
everything which dissolves in water. In other words, the color materials
such as watercolors, poster colors, color inks, dye, and so on belong to
this group. If we try to force them to coexist, a fight happens since they
repel each other. Patterns generated by overcoming these resistances make
us feel profoundness and mystery coming from accidents. This is an extremely
good technique to pursue textures and materials.
