Ecoline and water colour paint can be mixed without a problem,
but whether this is wise depends on what you intend to do with the
painting.
An important difference between both types of paint is that water
colours are made on the basis of pigments and Ecoline on the basis
of dyes. When choosing the pigment for water colours it is
important that the lightfastness of the pigment is optimal so that
the colour does not fade under the influence of light. This choice
can unfortunately not be made for dyes as the majority of dyes have
a poor to moderate lightfastness.
If a painting is made with the intention of hanging on the wall
for a long time (and therefore exposed to light) it is best to use
only water colour.
If the painting has only a temporary function, then the specific
properties (the transparency and colour intensity of dyes are
unparalleled) of Ecoline can provide many advantages. Consider, for
example, illustrations, designs and presentations. An illustration
would be reproduced in, for example, a book or a magazine, and a
design functions as a starting point for arriving at the final
product. The original can then be sealed and stored.
The carbon black pigment in Indian Ink is extremely fine, less
than 2 microns (1 micron = 1/1000 mm). These particles are in
constant motion in the ink, continually bumping into one another.
The special preparation method of the ink ensures that they do not
form lumps with one another. If a large amount of water is added
too quickly, however, the binder (shellac) that surrounds the
particles dissolves. The particles then clot to form larger
particles and sink to the bottom. When, therefore, the ink is
diluted the water should be added slowly and mixed to prevent this
from happening.
No, Talens Indian ink and Talens Drawing ink are not suitable for tattoo application.
These products are exclusively formulated and intended for applications on paper. For tattoo application these products are not tested, neither in terms of technical aspects nor in terms of health aspects. Besides this, more and more countries have special legislation for tattoo-colorants. The mentioned Talens products do not fulfill these requirements. For these reasons we label these products with the wording "Not for tattoo".
