Hallo thar, I've put this under painting tutorials because it's intended to inform you on water resistant inks, if you want to watercolour over them.
FW acrylic ink, still my favorite, thicker consistency so more sticks to my nib and I don't have to dip as often. Isn't sticky when it's drying.
Higgins Black Magic comes recommended by some fairly established Deviants, very thin consistency, had to dip twice just to write the name. still very nice if I can find a nib that holds alot of ink.
KOH-I-NOOR consistency sort of in between the other two, lifted most quickly when re-wetted but still not bad. very black, gets used by print students to block light during silkscreen making.
So all in all, I'd use any one of them twice, though the thicker FW ink with simpler pen nibs. I've tried several sorts of coloured inks and most of them bleed when re-wetted, even FW, making black inks no comparison for coloured inks of the same brand. Please note that most inks will eventually lift if you keep rubbing them with water, so be gentle and decisive with your brushstrokes. Letting the drawing cure for a day or two before painting over it will help prevent bleeding and smearing.
This was done on cheaper watercolour paper, the stuff with those mechanical wide dimples in it almost like a fabric texture. You'll likely get different results from papers with softer surfaces.
I used a archival pen, and is okay but I wish it had a softer tip so I could control the thickness better... But so far I've had no problems with bleeding or lifting!
AND I ADORE THE RAINBOW BIRDIES. Just sayin'.
I just like how drawing and watercolour work together, most watercolours I see don't involve ink.
it is a bit fidgetty.
