Smooth Lines on scanned Image

I am having trouble trying to find a way to take a scanned line art picture and smooth out the lines in photoshop. The original artwork was done on paper with a black marker. The lines are pretty ruff though. I want to smooth out all the lines without using the pen tool to path out all the lines and refill. please help if you have any ideas. Thanks

This is a process I use at least 3 times a week with clients lineart.

Make a 600 dpi "grayscale" scan of the lineart, once the image is up in PS hit cmd/ctr L to bring up the levels pallet...

In levels, with "Preview" checked opt/alt click the highlight histogram arrow (the white on on the right) Holding opt/alt while you drag the highlight arrow toward the left will start changing your image visually... what it shows you in WHITE while doing this "IS" white.... so drag it to the left untill everything is white EXCEPT your lineart....

Now do the same thing with the Shadow histogram arrow, dragging it to the left.... What it shows you while doing this is 100% BLACK....

What you are doing is insuring your lineart is dense black and your background has a 0 (zero) value (eg. white)

When you like what you see click OK you close the levels pallet...

Now cmd/opt 1 (ctr/alt 1 in windows) this selects ALL the white pixels so you want to invert your selection.... cmd/shift I (ctr/shift I in windows)....

Now all your BLACK pixels are selected.... hit cmd J.... (ctr J in windows) that will copy your selection to a new layer. At this point I generally Make another copy of my newly created layer to insure I have an untouched layer at this point.

Hide your background layer to see what you've done... Next is the tedious part... get out your eraser and pencil and clean that joker up...

Now when I do this for print graphics I generally clean it up... Add a layer filled with white behind it and save it as a tiff file... followed by changing it to Image>Mode>bitmap... 600 dpi

But that depends on what you are going to do with it....
