The halo is due to the jpeg compression which introduces blocky artifacts on details to reduce file size. Black and white / lineart pictures should be png since it's lossless, but still small for pictures of that kind.
I suggest putting a layer underneath the lineart and set the lineart layer to multiplication, that way you will be able to draw below the lineart with it blending on top of it.

This is a cry for help. How can I separate the lineart from a flat image created in SAI in Photoshop? When I tried to move the lineart David kept getting a weird halo around his lines
And I dont know how to color in SAI because Im a noob to coloring on a computer
Anyway uhh x enjoy???
