The term watercolor implies a painting method, the medium of the painting and even the artworks where paints are suspended or dissolved in water. The medium on which the watercolor painting is done often vary still the commonest of all is the paper. Some other types of watercolor canvas include papyrus, bark papers, plastics, vellum or leather, fabric, wood, and canvas.
Watercolor canvas is especially designed sturdily to support the paint and can bear the whole painting process. The watercolor canvas is made thick. The surface of the canvas varies in its smoothness from rough to smooth. A water color painting done on a rough canvas looks different from a similar painting done on smooth paper. Watercolor painting is also done on paper but there remains some difference between the two. The painting done on a watercolor canvas differs in following ways:
- To 'fix' a layer of paint, you need to paint over it with a clear acrylic medium.
- The paint can be lifted off very easily.
- The canvas stays wet for long than a paint done on a sheet of paper would.
There are certain advantages of doing painting on watercolor canvas all discussed below:
Watercolor Canvas, Lifting Capabilities:
In comparison to paper the lifting capability of a canvas is more than paper because of the greater durability of canvas than paper. In the watercolor canvas the color can be lifted by simply wetting the area to be recovered using a damp brush or moist cloth, and then blotting or brushing off the color. There is also provision of completely washing out the complete image and start again.
Watercolor Canvas, Signature Lifting:
While painting on paper you can sign your painting with ink or paint, but with Watercolor Canvas, you can accurately "lift" your signature for doing so apply clear water with a brush and then blot.
Glazing and Layering on Watercolor Canvas:
Because of the unique lifting capabilities of Watercolor Canvas, layering or glazing of the color may remove the previous color layers hence some special techniques are required for doing so. Use transparent liquid colors for glazing. Use Krylon for fixing each layers of the pigments used.
