Puff printing, also known as puff ink or puff screen printing, is a popular method used to add texture, depth, and visual interest to various garments, including t-shirts, sweatshirts, hoodies, and more. In this type of printing, you can elevate your designs to a whole new level by incorporating unique and eye-catching effects.
The process involves using special puff inks that contain a blowing agent. When heat is applied, the blowing agent expands, resulting in a raised effect that adds dimension to the printed design. Not only is puff printing visually appealing, but it also offers durability. The raised design withstands regular wear and wash, making it suitable for everyday use. This makes it a popular choice for custom apparel, promotional merchandise, and even sportswear.
In this blog, we will guide you through the step-by-step process of puff printing, providing you with useful tips and insights to help you achieve successful results, and puff printing advantages and drawbacks. So, let’s explore the world of puff printing.
How to Puff Print Step-by-Step Process
Material and Equipments For Puff Screen Printing
- Puff ink
- Screen and frame
- Emulsion and scoop coater
- Heat source
- Palette knife or spatula
Preparing the Design: Begin by creating or selecting a design that you want to puff print on your garment. Keep in mind that simple, bold designs work best with puff screen printing. Intricate details may not translate well due to the raised effect. Once you have your design ready, transfer it onto a transparent film or create a digital stencil for screen printing. Cotton fabric is best for puff ink.
Preparing the Screen: Apply emulsion to the screen using a scoop coater, ensuring a smooth and even coating. Let the emulsion dry and then expose the screen to light with your design stencil in place. This process will create a stencil on the screen. Rinse the screen with water to remove the unexposed emulsion, leaving behind a clear design stencil.
A mesh count between 90 to 110 threads per inch ( TPI ) is commonly used for puff screen printing, it allows for a higher deposition of puff ink, resulting in a more pronounced raised effect.
Mixing the Puff Ink: Follow the manufacturer’s instructions to mix the puff ink thoroughly. Make sure the blowing agent ( puff additive ) is evenly distributed throughout the ink. Use a spatula or a palette knife to achieve a consistent texture. You can add 10 to 20 % puff additive by weight to your standard plastisol ink.
For example, 100 grams of ink requires 10 to 20 grams of puff additive.
Applying the Puff Ink: Place your prepared screen onto the fabric, ensuring it is aligned correctly. Apply a generous amount of puff ink onto the screen, just above the design area. Use a squeegee to spread the ink evenly across the stencil. Apply enough pressure to push the ink through the screen and onto the fabric. Ensure that the ink covers the entire design area.
If you want more depth in your design you can stock ink 8-10 times with a squeegee, and dry each layer before applying the next.
Curing the Print: Once the puff ink is applied, carefully remove the screen from the fabric. Transfer the printed garment to a heat press or a conveyor dryer. Apply heat according to the manufacturer’s instructions. The heat will activate the blowing agent in the ink, causing it to expand and create the raised effect.
Types of Puff Printing Techniques
There are several types of puff screen printing techniques, these techniques allow designers and printers to create unique and eye-catching designs with raised and puffy textures. Here are some common types of puff ink techniques.
Raised Puff Printing, is the most traditional and widely used technique. It involves applying a special puff ink onto the fabric using screen printing. The ink contains additives that expand when exposed to heat, resulting in a raised effect. The level of puffiness can be controlled by adjusting the ink thickness and curing conditions.
Foam Puff Printing, involves using foam-based puff inks. The ink is applied onto the fabric, and when cured the foam expands, creating a three-dimensional effect with a softer and spongy texture.
Glitter Puff Printing, combines the sparkle of glitter with the raised effect of puff printing. Glitter puff inks contain glitter particles that are suspended in the ink base. When applied and cured, the ink expands, creating a raised glittery texture on the printed design. This technique adds a touch of glamour and shine to the final product.
Suede Puff Printing, aims to replicate the soft and velvety texture of suede fabric. Suede puff inks typically contain additives that create a fuzzy or suede-like surface when expanded. This technique is often used to add a luxurious feel to designs, giving them a soft and velvety touch.
Metallic Puff Printing, involves using metallic puff inks to create a raised metallic effect on designs. The metallic particles in the ink provide a shiny and reflective surface when expanded. This technique is particularly popular for creating eye-catching and glamorous designs that stand out.
Glow-in-the-Dark Puff Printing, combines the raised effect of puff printing with phosphorescent additives. The ink is applied onto the fabric, and when exposed to light, it absorbs energy. In the dark, the ink emits a glow or luminous effect. This technique is commonly used for creating unique and attention-grabbing designs with a glow-in-the-dark feature.
Tips for Successful Puff Printing
- Test your design and puff ink combination on a sample fabric before proceeding with the final prints.
- Ensure that the screen is properly tensioned to achieve clean and crisp prints.
- Experiment with different ink thicknesses to achieve varying degrees of puffiness.
- Take care not to overcure the puff ink, as it may result in discoloration or loss of texture.
- Clean your equipment thoroughly after each use to prolong its lifespan and maintain print quality.
