Here is an inexpensive and easy technique for creating an effect like scratchboard art.

Step 1: Supplies

1 write-on transparancy sheet (I used the kind used for overhead projectors)
1 crayola dry erase marker (black)

This crayola dry-erase marker is awesome. It pumps out a really bold black line better than others I've tried.

Step 2: Coat the transparency in dry-erase ink

start at one edge and apply the marker in even strokes. Make each stroke go the same direction each time. See the video.


Step 3: Scratch your design in

Etch your design by hand onto the transparency now that it's all coated with dry-erase ink.

Use some sort of blunt tool to scratch your design onto it. I used the wrong end of a paintbrush, but you can use almost anything. I've also had success using a pencil eraser to remove the dry-erase ink. A clay modeling tool works too.

If you make a mistake, you can just color back in using the dry-erase marker, let the ink dry and re-do it.

Be careful not to rest your hand or fingers on the drawing, or the dry-erase ink will come up off of it and leave a nice big palm print on your artwork.

You might want to leave some margin of non-drawing around the edges so you can handle the thing easier, without getting fingerprints in it.

Step 4: Put something colorful underneath

Lay the transparancy sheet over a colorful surface so it shows through the clear bits you scratched away.

I used my cheap watercolor block with some random paint on it.

Step 5: Scan it in

Once your design is complete, you can lay it over the colorful background and then scan the image in on a flat bed scanner as a way to preserve it.

In other words, create a two-layer sandwich with the ink facing up. This means you can re-use the colored background, and wipe and re-use the transparency as needed. [thanks Canida for the clarifying words].

Be sure to wipe away any dry erase ink that may get onto your scanner surface when you're done.

This is a very inexpensive way to create scratchboard art. Have fun and be fearless.

Cool! So just to clarify - I think you're not placing the transparency ink-down on your watercolor pad to transfer the ink to the colored sheet, you're creating a two-layer sandwich with the ink facing up. This means you can re-use the colored background, and wipe and re-use the transparency as needed. Does it work the other way around, transferring the dry-erase ink to the watercolor paper?

I added some new wording to hopefully clear the confusion up. Thanks!

whups, I see, I didn't explain it well. Yes, the transparancy sheet is laid over the colored surface so it shows through the clear bits you scratched away. The other way around, as you suggest, definitely would not work.
Why not skip the transparency and do the scratching right on the scanner?

ha, very funny
That's awesome! Does your scanner not produce any glare on the image?

Thanks! Oh, the third and fourth pictures on the first page are made by my scanner, the others by my camera.

Okay, now I rearranged the pictures so the first image is the one from the scanner, it's much cleaner.

I have a little scanner from Canon, pretty nice really, only $50 bucks when I bought it (it's gone way up now for some reason) and it's as light as a pad of paper: canoscan
