A reverse print is when you flip a t-shirt inside out, and print on the inside of the shirt. Some of the ink shows through on the other side, and it results in a natural texture determined by the qualities of the fabric.
You can achieve different looks, depending on the color and thickness of your t-shirt fabric, the color and type of ink, and also how much squeegee pressure is applied.
This Noosa Longboards tee uses a slub textured fabric, which results in uneven horizontal streaks in the print.
On dark shirts, you will typically need more ink and pressure for your graphic to show through, compared to a light t-shirt.
You can reverse print with waterbase ink or plastisol ink. Discharge printing work well too.
Most often, you will want to use water based ink because it will have a softer feel than plastisol ink.
Remember, the ink is printed on the inside of the shirt so a softer print is better!
If you want to get the look of a reverse print without printing on the inside of the shirt, you can use Inside Out Textures for a realistic effect.
Inside Out Textures come in T-Shirt Design Master Collection 1, The Big 3 T-Shirt Design Bundle, and The Big 5 T-Shirt Design Bundle.
