The application process for Heat transfer paper and heat transfer vinyl is different. For heat transfer paper, the image is printed on the transfer paper first using a regular inkjet or laser printer. Then, the image is transferred onto the garment using heat and pressure.

For heat transfer vinyl, the vinyl is cut into shapes first using a cutting machine or scissors. Once the design is cut out, it is weeded, removing the unnecessary vinyl around the design. Then, the vinyl is heat-pressed onto the garment, adhering to the fabric permanently.

Heat transfer paper designs can last anywhere from a few washes to several years, depending on the quality of the transfer paper used. High-quality transfer paper can produce designs that can withstand machine washing with no issues. However, it may not be as durable as heat transfer vinyl under heavy use cases.

Heat transfer vinyl, on the other hand, has excellent durability and is one of the most long-lasting image transfer options available. Vinyl transfers typically last much longer than heat transfer papers, especially when the vinyl is of high quality.

The choice of using heat transfer paper or heat transfer vinyl depends on the specific needs of the project. Heat transfer paper benefits are that it can create excellent printing quality, photographs, and full-color designs. In contrast, heat transfer vinyl is better for cutting simple designs, letters, and durability.

Additionally, the process of application and materials differs in application time, transfer pressure, and cutting software. It's essential to ensure that you select a transfer method that best fits your needs to achieve the best result.
