One of the advantages of digital printing is the ability to transfer ink to different materials and
substrates. However, most of these materials require a special type of ink that would be permanent.
Colour fastness test against friction is a test to determine the long-term use quality of printed products.
The purpose of this test is to determine the quantity of colour that can be transferred from the surface
of a coloured substrate to a test cloth by rubbing. Also surface macro nonuniformity before and after
colour fastness test was investigated. The results show significant surface change after colour fastness
test on plastics, and a slightly improvement on other tested materials.
