Is this ink compatible with other Fine Line techincal pens in general?

The packaging doesn’t say the ink is for any specific technical pen so I should have thought it would be OK. I use mine in a staedtler marsmatic 700, 0.35 and it’s fine

Is it suitable for calligraphy on canvas??

The ink is very thick and black so you may need to dilute with water or a medium. Test if possible on a small area of the canvas first if possible (Perhaps the side or reverse) to make sure it will dry and adhere to your surface the way you want it too. These drawing inks are not designed primarily for canvas but for paper. As the cost is low for this ink, might well be worth a try.? Hope it goes well. Acrylic inks are another possible alternative that are designed for canvas, but not nearly as thick.

Could you use this ink in refillable Calligraphy Pens?

I'd advise against it - these inks use binders and other chemicals to make them water resistant and those chemicals will solidify in all the wrong places in your calligraphy pen. The solvents you need to break the ink apart may do damage to your fountain / calligraphy pen - they are not designed for that kind of cleaning.

Suitable for rotring artpen?

Yes I would say so, I bought a Rotting ink pen that uses ink cartridges and this ink for the TechnoArt ink pen. It's similar but cheaper in price.
