Gouache Or Poster Paint?…
What is gouache paint and is it exactly the same as poster paints? Well, this really is a paint that is opaque. You can use this to reproduce materials and cards, because of this factor. I have known friends to actually scan prints to go on to make printed items.
I think it is fairly safe to say that many people are under the impression that poster paints are exactly the same, but this is not the case. Poster paint is a cheap paint consisting of proteins and a substantial amount of egg.
This creates a different type of surface and it is highly likely that you will end up with your paper wrinkling. You will find that it is very cheap, so maybe this is why it is used so much for craft projects.
However, this paint is in great demand for use with children. After all, it is one of the safest paints around, so it is very useful in schools etc. Also being an ideal choice, being that it is inexpensive. The only downside is, that it is not particularly durable and it can flake.
Gouache may appear similar to poster paints, this is not so, as this medium has a water base. The colour finish obtained, is much improved in comparison to poster paints. Gouache is packaged in tubes and poster paints are in bottles, so they are easily distinguished.
Gouache is deceiving when used, as we have all experienced, as you will find, that when they dry, they do not reflect the same colour they were when they were wet. Dark shades seem to dry lighter and light shades dry darker, in the main. They also have a matt finish.
You could try using this paint, if you are into landscapes, using a cold pressed paper. I would choose the 140lb. It has so many uses as it can be used wth all different papers, on colllages, for decoupage and many other surfaces.
Gouache has gum arabic added to its pigment which makes a nice consistency, similar to cream, and therefore produces a good flow when you use it. It can vary however, as not all paints have a similar amount of chalk added to the pigment. You will notice too, they may be labelled as permanent or semi permanent.
Artists often use this as their first layer of paint wash on their work. As for the type of brush you should use with this, I would say a sable, or synthetic sable brush. Should you make errors these are easy to rectify and can easily be repainted. You can also add thick layers when you are nearing the end of your painting.
This can crack as the paint is quite thick, so I would not recommend painting too many layers, but whatever you may do, refrain from diluting this too much with water. You can put these in a glass frame, but you would need a passe partout mat to stop them touching the glass.
This paint is used quite predominately by artists in the commercial field for advertising, posters, designs and general illustrations. This medium is used by famous artists like Matisse for instance.
