Solvent or alcohol inks are NOT compatible with alcohol based markers.
For best results use pigment based inks and allow ink to dry or heat set before coloring.
We recommend if you want to just colour then use Memento Dye Based inks (comes in a variety of colours including Tuxedo Black).
If you do not own any Memento inks then you can use a pigment ink, but you must set it with clear embossing powder before you colour otherwise it will smudge. Do not used coloured embossing powders as they will damage/stain your nib.
