removing blue sketch lines

By oomizuao
hopefully this helps :)

there are probably a lot of different ways of removing blue sketch lines, but this is the best method that I've tried yet.
It should work on red lines too, but I don't sketch with red so I dunno how to remove red lines. It's probably the same, only that in Curves and Channels you remove different colors than you do for the blue lines *shrug*


This is my method. I'd previously learned two methods for removing blue lines, but they didn't completely remove the blue lines, at least not without leaving traces of gray instead of blue or messing up the lineart..
This method that I made completely removes the blue lines! So I thought I'd share this method to make things a bit easier for my fellow Deviants. <3

This works the best if the black lines are drawn with a pen/pigment liner/ink, and not pencil. I think this method would remove some of the details if used on pencil art.. hm... gotta figure out a method for that too.. ^^;


Hope some of you find this helpful :)



also, the blue I use is Pilot Color ENO 0.7 leads for mechanical pencils. These are awesome and can be found at [link] and probably other stores too :)

I recommend sketching with red (magenta) or blue (cyan) if you like drawing traditionally and coloring digitally, without having to erase your sketch lines with an eraser which often leaves the paper, well, not so white anymore.
I know a lot of professional cartoonists sketch with blue before they ink their work. And it does make digital coloring so much easier.

Another thing you can do, if you want to color your lineart traditionally without ruining the original: remove the blue lines in photoshop like in this tutorial, print out a copy of the black, clean line-art and color the copy :) I do it as good as all the time when I want to color traditionally, 'cos I'm afraid of ruining the original ;D

just some tips :)


feel free to ask me any questions you might have, and I'll try my best to answer them! <3

What settings do you put your scanner to? Mine won't scan color pictures without making the white bits an awful color of grey. :C

Thank you so, so much for this tutorial! I had already lost all hope for ever getting my lineart cleaned up from the blue pencil that I used, as I had completely forgotten how it was done! You absolutely saved my day! I think your tutorial is helpful, detailed, and doesn't leave the reader in any sort of tough situation where there's not enough guidance. Thank you, great work!

I ordered from this company, and it's taking quite a while. How long do they normally take for you?
oomizuao's avatar
I think it took 14 days or a bit more for me ^^; but you could always contact them, I guess, and ask any questions you might have :)

Alright, thanks...

i thought it could go easier, that you could use a layer for your sketches and then take another layer for you inking and then delete the sketch layer...
