Make line art look like a sketch in Photoshop?

[Serene_observer5E99]

Does anyone know of a filter or a method in Photoshop that will make digital line art look like it was sketched?

I have an image that is smooth solid black line, but I want it to look hand-drawn (without having to hand-draw it). Any suggestions?

How to turn photos into pencil sketches using Photoshop

-edit-

That tchnique probably works better with photos.

I changed tack and did it the old-fashioned way.

My attempt causes me to remember the scene in the movie Contact where the scientist Jodie Foster said they should've sent an artist into the worm hole.

You could get an outline using the Sketch > Photocopy filter

I have removed the background to show what is left. 

If you want to do that use Layer Style > Blend If and drag the highlight end slider to the left.

To knock it out completely, make the layer a Smart Object, and immediately Rasterize it.

This is what it looked like with the white background

What someone like an illustrator/cartoon artis etc would do, is to hand ink in the lines manually.  I personally am a bit shite at that and I have an Intuos 5, and an Xencelabs Pen Display (like a Wacom Cintiq).  It is much easier on the Pen Display, but I still find it difficult to follow the lines.

So what a lot of people do, and that includes industry greats like Bert Monroy, is to stroke workpaths.  You can get perfect placement that way, and stroke the path with whatever preset works best for you.
