I think I tried inking my pencil drawings before, but I’m getting better at this. I tried doing this last year, I wasn’t that good at it yet and I didn’t have whiteout markers then. But I’m getting better at this, so practice really does make perfect. When it comes to the kinds of ink that make a very dark black, there’s one in the form of Blink but I think gel pens like the ones from Panda tend to be darker because the material holds more pigment so you get a dark black this way. The sign pens from Artskills are dark enough to be legible, but look pretty grey compared to the Panda pens.
To be fair there are Philippine pen brands that have ink just as grey as these, if only I made somebody buy those it would be fun to check which ink is darker. But a really black ink would be fun as it contrasts with white better and it still looks pretty black compared to the black inks of other pens, which looks rather grey and I could get that’s how people feel around Blink. It’s really dark, so dark it makes all other black inks look grey. Looks like the efforts to make a black ink have really paid off, that’s something that I like.
For a regular (read greyish) black ink, almost any pen would do but for a darker black go for gel pens like those from Panda for instance if you can’t afford Blink. It’s not the same thing, but it’s as close as one gets within one’s budget and logistics.
