This little "homage" was drawn a couple of days ago by fan who prefers not to be credited. It was drawn on blue lined paper, which was a bit of a challenge... Converting the art to b/w and then hand painting the lines out, worked well enough, but I also had to use a cloning tool to mask parts of the art that still had lines through, but it seems to have worked well enough! In any case, it was a pleasing, cheerful little sketch that I much appreciated.

If you're working with black and white and using Photoshop, the easiest thing to do is duplicate the blue channel (in the Channels palette), do a slight levels correction to remove any faint remnant of the blue lines (which should be slight, since blue=white in the blue channel), and use that as to create a new black fill layer. Hmm, it's a little hard to explain just in words. Maybe it calls for a tutorial video. Stand by... I can make this a lot easier next time you have to do this. :)
Taral, maybe give this method a try the next time you need to undertake something like this... https://www.deviantart.com/qtmarx/a.....shop-873919662
There are two things I can think of; one you can control and one you can't. Assuming you were starting with colour scan (I think you said you converted it to B&W), it needs to remain a colour scan. There has to be blue colour information to differentiate the channels and give you a blue channel that makes the lines as light as possible. If you convert it to greyscale, all the channels will be exactly the same and you lose the advantage you'd have in the blue channel. It's akin to sewing your field with rocks before you start plowing. You can go greyscale after the work is done, but not before. The second possibility is that the original blue lines were so dark as to be practically black; a very dark navy blue. In that case, this technique isn't going to help all that much. It works best the lighter the blue actually is, and the less it's mixed with other hues. But, given the right circumstances at the outset, I've found this process yields terrific results.
I don't recall, but I think I wouldn't have tried to remove the blue lines after converting to greyscale. That would be rather boneheaded. But it might have been that the blue lines were just too intense to remove with a filter. I suspect, however, that there is just something simply I needed to know, but didn't know it. I may still have an old Photoshop book, but I have always hated trying to learn anything from it.
Go ahead. Brighten my day!
I wondered if there's some way to remove the blue lines, and perhaps Watercollar had it. I do know that a lot of newspaper comic artists did their 'underpainiting' with blue pencil. A blue filter on the copy camera lens eliminated most of it.

Back in day, we used to animate the roughs in blue pencil. If we were working cheap, we'd do the cleanup over the roughs. They were photographed—or later, scanned—using a process that didn't "see" the colour blue, so all but the messiest, hardest roughs automatically disappeared. When I started working with Photoshop in the mid-90s and was introduced to the concept of channels, I had tons of artwork that was either cleanups on blue roughs, or doodles on lined paper, and when I happened to look at the channels of these scans and realized the blue was faint or non-existent, well, the angels sang. I don't have as much use for it these days, of course, but Taral's chore brought it all back. :)
