Glow-in-the-dark puff printing on shirts is a creative and eye-catching printing technique that combines two unique features: a raised 3D effect (puff printing) and the ability to glow in the dark. This method is used to create designs on shirts that appear as regular prints during the day but emit a glowing effect in low-light conditions or darkness. It's particularly popular for adding fun and engaging elements to custom apparel.

The design is printed on the shirt using a special ink that expands when exposed to heat (puff ink). This process creates the raised 3D effect on the fabric. The puff ink is applied to the specific areas of the design where the raised effect is desired.

Once the puff ink has been applied and dried, a layer of glow-in-the-dark ink is added on top of the puff print. This ink contains phosphorescent pigments that can absorb and store light energy when exposed to light during the day.

Once the shirt is in a dark or low-light environment, the glow-in-the-dark ink will emit a soft, luminous glow, creating a captivating visual effect. The glowing effect may gradually fade as the stored light energy is released over time.

Glow-in-the-dark puff printing adds a unique and captivating element to shirts, making the design stand out and generating interest. The glow-in-the-dark effect ensures that the design remains visible even in low-light or pitch-dark conditions, making it ideal for safety-related applications as well.
