Is this ink waterproof?

Hello,It is water‐soluble.It is not waterproof.Thank you.

How can I thin this ink for small tip technical pens without diluting it?

Thank you for your interest in our Rotring brand. This ink is only meant to be used with our Isograph line of pens and is not suitable for non-isograph technical pens.

Does this ink work with alcohol markers?

If you're asking if alcohol dissolves (smears) this ink, no, not in my experience. I use the Isograph pens (with this ink) for my marker drawings with no problem at all. I also use it to line my watercolor stuff, also no smearing.

Can i use this ink with a rapidograph pen or only rotring isograph pen?

Please be advised that only rOtring Isograph pens have refillable ink reservoirs ideal for drawers using bottle inks. The rOtring Rapidograph pens are compatible with rOtring 's unique capillary cartridges exclusively.
