Concentrated pigments from Sebastar water-based screen printing inks, to be added to an extender base. Each of our ink colours are also available as a colour concentrate pigment. These highly pigmented Colour concentrates are compatible with the Sebek water-based inks. The concentrates can be added to any of the ink colours in a ratio between 1%-10% giving you the flexibility to create an endless range of ink colours. You can also mix your own ink by adding the colour concentrates to the transparent base.  We find a ratio between 3% - 10% is best.
