SCRATCH ART
|
Scratch Art is a graphic technique. It is used to create value drawings. Most common is a black-and-white technique. Also popular are metallic backgrounds – they make a drawing look like etching.
Scratch board is a paper (or foil) board that is covered with wax or gesso and coated over with black ink. Using scratch tools (stylus, scratch brush, or scratch knife) you can create value drawings by scratching off the black ink and revealing the board beneath. This technique is similar to drawing with white pencil over a black paper. |

You can use a variety of strokes as you scratch. Depending on the object that you are working on – you should use different value techniques to show texture of this particular object. As a rule – USE SMALL STROKES!!!! Smaller the stroke – easier it is to control the scratching process. Remember, you cannot “undo” or erase a scratch. Once it is there – it stays. That’s why it is a good idea to take your time and scratch with smaller strokes – in case you mess it up – you still might be able to fix it and not start over. Which saves time in a long run! Another rule – don’t press too hard on the tool – it will rip the paper. TAKE YOUR TIME!!!! . |
EXAMPLES OF VALUE SCALES

PRACTICE: VALUE SCALE
DUE: Thursday March 19 Watch the video on the left to give you a idea of what the practice project is about. As you can see it is possible to show values and textures just by scratching small strokes. Assignment: Create 3 value scales. Each scale should be 1 inch x 6 inches. Two scales should have 6 boxes in them that are 1 in x 1 in. One scale should demonstrate the crosshatching technique (from light to dark) the other the hatching technique (light to dark) and the third value scale needs to show a variety of different lines and doodles. Turn in all three practices on Thursday March 19. Upload them into your online portfolio when you're finished. |
Texture Experiments
Each student will be provided a 2"x2" piece of scratchboard to try scratching. Use different tools like a thumb tack, X-acto knife, and the scratch tool. Also try hatching, cross hatching, dashes and dots. Create a small value scale using a texture that gets darker and darker. Have an are that is totally scratched out. See the example to the left that shows what your piece practice piece may look like. It does not need to look exactly the same or need to be labeled. |
