Ask 10 shirt artists the best way to airbrush onto black shirts and you may very well get 10 different answers. However, all should agree that, if done well, black shirts provide a canvas for some of the most awesome examples of T-shirt art.
This article shares a technique that I’ve practiced for 14 years involving the use of bleach in lieu of white paint to establish a white base for spraying transparent colors. This innovative approach clearly makes the color-on-black process easier, and also lends itself to some very interesting textures and effects. Balck shirts I have painted using this method are some of the most popular and attention-grabbing displays, I’ve used.
For the bleaching process, begin by stretching the T-shirt tightly over a piece of cardboard or shirt board. This will protect the areas of the shirt you don’t want to bleach (for this demonstration, a 100-percent cotton Fruit of the Loom shirt was used). Not all black shirts produce the same results when using bleach and you may have to experiment with different brands in order to find one that gives you the results you want.
Begin by mixing a 50/50 solution of bleach and water in a trigger style spray bottle. Set the spray pattern to stream and spray the shirt. The pattern you spray should be random and have a speckled look to it. Covering the shirt with too much bleach will cause the shirt to have a uniform color and lose some of the character gained from this technique.
Once you have a good pattern defined, switch the spray bottle to mist. The mist spray pattern will give you a solid, more uniform look than the previous stream pattern did. Begin by saturating only the center areas of the shirt where the focal point of your design will be, leaving the drips and splatters around the outside edges for effect. These areas can be used later to your advantage in the finished design. Once, you have achieved a look you are happy with, let the shirt sit for about 10 minutes to give the bleach time to work. At this point the bleached areas probably will have an orange tint to them; do not worry, this will change. Carefeully remove the shirt from the board, trying not to let any wet areas touch the remaining black parts of the shirt. Place the shirt into a washing machine that has been prefilled with water. Wash and dry the shirt as you normally would to remove the bleach.
Once the shirt has been washed and dried, stretch it tightly onto the shirt board. Using an Ebony drawing pencil, make a detailed drawing of the bear into the shirt. Because of the bear’s dark fur, these pencil lines won’t show through in the final image.
Start the painting by spraying in the areas of the teeth using opaque white. The overspray from colors used later will land on the teeth, giving them a stained and more realistic appearance. Small details like this are easily overlooked but can help make a painting more convincing to your customers.
With createx light brown, using short dagger-like strokes, start defining the fur in the chin area. Create a sense of shape by curving these strokes slightly in unisom from top and bottom. This will create the illusion of a tuft of fur on the bear’s chin.
Continue with the longer fur on the chest and neck area of the bear using longer, more tapered dagger strokes. Varying the length and direction of these strokes will create realistic, thick fur. Refer to your reference often and be very careful to precisely follow the direction of the animal’s fur.
Using tight dagger strokes, define the area of short, flattened hair on the bear’s muzzle and around the eyes. While working on this area, sculpt the bear’s nose with light brown, using a combination of hard lines and soft shading.
Finish the brown areas of fur around the eyes and on the forehead of the bear. At this point, furs should look natural and transition well from one area to another.
To give the bear its natural golden appearance, spray a glaze of Createx yellow moderately over the whole painting except for the mouth area. Be careful not to add too much color. Using florescent orange, very lightly glaze over the yellow. You only want to take the edge off the yellow, not shift the color to orange.
Use black to fill in the nose area leaving some of the brown under painting to show through. This gives the nose added depth and a more natural appearance. Then, add the darker shadow areas of fur using opaque black, mimicking the strokes used earlier with the ligh brown.
Finish the darker areas of fur around the bear’s head. Follow the same direction and angels as you did earlier but don’t completely cover the black strokes. This creates dimension and depth in the fur and makes the bear blend well with the blackness of the shirt. Use the black to define the areas around the eyes and brown. The fur should look thick and have a nice flow to it.
Start defining the teeth using a mixture of transparent gray with a few drops of ultramarine blue. Use this same color to fill in the shadow areas of the mouth, lips and gums. This color will serve as an underpainting for the next step.
Spray florescent pink lightly over the gray areas in the mouth, staying away from the teeth. To create a little more depth, spray a light mist of florescent violet in the shadow areas around the mouth. Add a little light brown and yellow to further â€œstainâ€ the bottom areas of the teeth.
Use opaque black sparingly to fill In the deepest shadows o f the mouth and lip.
Add color to the eyes using red to define the darker areas around the pupils and outside edges, and florescent orange to fill in the brighter areas in the middle. This makes the eyes look bright and life like.
Finish the shirt with opaque white by adding small highlights to the nose, mouth, and eyes.
