So you want to know how to ink watercolor? It’s actually a very simple three step process. First you draw it in pencil. Then you ink it. Then you erase the pencil after the ink dries.
That’s all there is to it. But, let’s not end this article just yet. You probably need a lot more detail than that.
Drawing your piece
There are two types of artists who use watercolor. Some of us just paint. I’m not that type.
I’m the type that has to ink watercolor. The drawing is the most important and the most difficult part of the entire process for me.
That’s because I do pinup art. You pretty much have to draw a reference for it to be any good.
That said, you could keep the drawing in pencil. Or you can ink your painting.
I’ve done both, and every single painting you see in my Opium Tales store is inked. To my eyes, it looks way better.
But let’s go back to drawing the piece. Some folks use high tech or expensive pencils. I just use plain America’s Pencil HB 2 pencils. They’re good pencils. Then I put those erasers you get in a ten-pack to put over the eraser it comes with. I swear, I probably do just as much erasing as I do drawing.
I strongly suggest you try different kinds of pencils. Try the high tech ones and try the simple ones. There is no right answer here. You need to find the tool you’re most comfortable with. Once you find that tool, you’ll more than likely use the same tool for years.
Inking the piece
Now the fun part. If you mess up the inking, you’ll need to use a little bit of watercolor ground to fix it.
Inking is the scariest part for me. Drawing is easy. You can always erase. Once you ink, it’s permanent.
The kind of ink to ink watercolor? Good question.
Once again, try different tools until you find the one you like. Now this is very, very important. You need to buy a permanent ink that is waterproof. If you don’t, it will smear all over your painting once you add water. I’ve made this mistake once and I’ll never, ever make it again.
I have one ink brush and I never use it. It’s simply too thick for me.
If you’re doing something with super fine detail, you can’t use an ink brush. However if you’re doing something a little bit more abstract, ink brushes look cool!
I actually love how ink brushes work. But since I’m doing pinup art, I have no place for it. It depends on what you’re doing though. You may love it.
This is what I use. Once again, it needs to be waterproof.
I swear by Sakura Micron pens. I think they’re dang good pens for watercolor and gouache.
Personally, I’m using the 005 because I need very fine lines. You may not need something that fine. Buy a few of these pens and see which ones you like the best.
Note that you need to wait until the ink is completely dry before going to the next step.
Hot tip - Store your pens upside down. They'll last longer that way.
Testing the ink first
Sakura Micron pens won’t run. But, one thing I learned the hard way, not everyone who works at the art store knows everything. I had one employee suggest a “great pen for watercolor” and when I actually started watercoloring, it ran all over the place and completely ruined the painting.
If you’re not sure, test it on your test notebook. You do have one of those, right?
If you don’t know what I’m talking about, they’re these little watercolor notebooks. Strathmore and Moleskin both make decent ones.
I don’t use them for anything other than testing and making notes. You can clearly see that I write in the thing just as much as I actually paint in it. It’s for experimenting only.
Erasing the pencil
Finally, you erase the pencil, leaving behind only the ink. All the shading, depth, shadowing, etc, you do with the watercolors. You won’t need to see any of the pencils.
For this, I either use the eraser I put on the pencil or a gum eraser. Either are fine.
Watercolor is transparent so if you leave behind any pencil, there’s a good chance it will show. Some of the pencil gets wiped away in the water. Some of it does not. So if you don’t want it showing, it’s in your best interest to not skip this step.
Make sure you’re not leaving any eraser residue behind. Wipe that off well, and you’re now free to paint!
How much ink to use
I’ve been asked how much do you ink and how much do you just paint?
Well, that’s up to you. For some paintings, I like to do more ink than others.
For the girls, I ink the outlines and let the watercolors (and gouache if applicable) do the rest.
But it really depends on the painting and how much detail you want to give it with it. Keep in mind, you do want to keep some of the magic for the watercolors. Totally up to you.
