Octopus Fluids Sheen Ink - Unicorn, 30ml

The fountain pen inks in this collection are water-based dye-based inks. The special feature of these inks is the so-called sheen effect, which makes the writing shine in a colour different from the base colour. This is made possible by a very high dye content. 
Sheening fountain pen inks are not new to the market, but a comparison often reveals that the variety of colours is limited, the sheen is very low or the inks smudge easily. Many sheen inks also contain glitter pigments to enhance the sheen effect. However, these can build up in the ink fountain and cause problems when writing.

How do you get the best sheen effect?

The intensity of the sheen effect depends largely on the paper used and the ink flow of the fountain pen. Use a fountain pen with generous ink flow and/or a wide nib. Glass nibs or calligraphy nibs also give very good results. 
On uncoated paper, especially very rough copy paper, the sheen effect cannot be achieved because the dye penetrates too deeply into the paper fibre and does not remain on the paper. Only the strong base colour of the ink will be visible.
For this reason, we recommend the use of high quality, very smooth, coated writing paper when using Sheen inks.
