Ill give it a try right now !!

youre welcome !! I hope it works ^^"

The thing is I don't use the move tool:( I’ll try the paint bucket lines thought !! thank you:))

the move tool thingy can blur your lines sometimes !
To fix it i paintbucket the lines till it looks clear ...
I think that coukd be the problem?

If not maybe it could be the pen size, but I just tested it and it didnt blur for me .. hm
