1. Vinyl Heat Transfer (HTV)

Vinyl heat transfer involves cutting a design outline from vinyl, applying heat, and transferring it onto a material.

This process is often used for simple designs, such as textual graphics, names, numbers, and logos on T-shirts.

The ease of use makes it perfect for single-colored designs, though printable heat transfer vinyl (HTV) allows for multi-color, detailed, and vibrant images to be printed, cut, and transferred onto fabrics using a heat press.

The transfer process provides an expanded range of possibilities, making it ideal for both basic and more intricate designs, enhancing the versatility of vinyl heat transfer.

2. Sublimation Heat Transfer

Sublimation heat transfer stands out when printing full-colored, realistic picture images on synthetic fabrics.

This method involves using sublimation ink, a type of dye that transforms into gas when heated.

The design is printed onto special paper with a sublimation printer, such as the Epson Sure Color Series, before being applied to the item using a heat press machine.

When pressure and heat are applied, the sublimation ink turns into gas and seeps into the material.

Once it cools, the gas solidifies, ensuring the design becomes a permanent part of the fabric, rather than simply sitting on top.

This technique offers vibrant, long-lasting designs that won’t peel or fade, but it works best on polyester fabrics or items with a special coating to accept sublimation ink.

3. Screen Printed Heat Transfer

Screen-printed heat transfer uses a manual screen printing technique to create vibrant designs directly on transfer films, often incorporating plastisol ink.

The printed designs are then heat pressed onto various fabrics, ensuring the top layer adheres firmly to the material’s surface.

This method is ideal for adding textured details and works well across multiple materials.

Pre-made heat transfer decals are also available, offering a convenient solution for applying designs to garments or other items.

The process ensures a noticeable touch, making screen printing a versatile and reliable choice for high-quality heat transfers.

4. DTF Heat Transfer

DTF heat transfer is a modern method where designs are printed directly onto a specialized film using a DTF or inkjet printer.

This process uses water-based pigments for high-quality, vibrant colors. The printed design is then coated with thermally activated adhesive powder, which bonds to the wet ink.

The film undergoes a curing stage, where the powder is melted at a specific temperature to ensure optimal adhesion.

Once cured, the transfer film is heat-pressed onto various substrates, including light and dark fabrics like T-shirts, hoodies, and even accessories like bags and shoes.

The controlled heat and pressure help the design to firmly adhere to the material, leaving a durable print.

This method is especially advantageous for custom apparel because it doesn’t require pre-treatment, making it ideal for creating unique designs on a wide range of products.
