Unraveling the History of Heat Transfer Printing

Heat transfer printing appeared on the scene with the growing popularity of polyester fabric. The textile industry required a more refined and efficient printing technique and heat transfer printing was born. Initially, the method involved printing patterns on paper using selective dyes known as the design stencil. This printed paper was then positioned on the fabric to transfer the design.

At the outset, heat transfer printing was limited to novelty items, like polyester tops and t-shirts. The impressive results opened more avenues for this technology. Today, heat transfer printing has evolved significantly and is a key printing technology for the textile and manufacturing industries.

The Heat Transfer Printing Process: Step by Step

Heat transfer printing is an exceptional method for transferring custom logos or designs onto apparel. This technique revolves around printing the design on paper before transferring the print to the fabric.

Here's a detailed walkthrough of the various forms of heat transfer processes: inkjet transfers, dye sublimation transfers, digital applique transfers, and vinyl transfers.

  1. Gathering the Necessary Supplies

You'll need an array of supplies and advanced machinery for successful heat transfer printing. Here's what you'll typically require:

  • Computer
  • Printer
  • Ink
  • Heat Transfer Paper
  • Cutter
  • Heat Press
  • Heat Pads
  • Heat tape
  • Heat resistant sheeting
  • Substrates
  1. Creating the Design

At Printfits, we give you the option of using a template design, submitting your own design, or getting help from our experienced professional designers to create your desired design.

  1. Printing the Design

Once your design is ready, it's printed on a specialized heat transfer paper. Based on the type of product and its application, one of the following inks is used: inkjet ink, pigment ink, or sublimation ink.

  1. Cutting the Design

At this stage, the printed design is trimmed using a vinyl cutter. However, this step isn't necessary for all processes.

  1. Warming up the Heat Press

This critical step involves preparing the heat press. The ideal temperature range for the heat transfer printing process is between 350-375F.

  1. Adjusting the Pressure

The pressure is adjusted based on the thickness of the fabric. Thicker fabrics require less pressure. Medium or high pressure is generally applied to various types of fabrics.

  1. Setting the Time

Depending on the type of heat transfer process, the timing varies. Here's the usual time allocation:

  • Inkjet Transfer Paper: 14-18 seconds
  • Dye Sublimation Transfer: 25-30 seconds
  • Digital Applique Transfer: 20-30 seconds
  • Vinyl Transfer: 45-60 seconds
  1. Setting the Substrate and Transferring in Place

The product is positioned on the plate, and the design paper is placed at the correct location in the pressing area.

  1. Pressing the Product

The pressing machine is fully set up by this time, and you can pull the handle or press the start button to press the design onto the fabric.

  1. Removing the Film

Once the timer on the press signals that the process is complete, the press is opened, and the film is removed. At this point, your heat transfer paper will be hot, and the design will be perfectly transferred onto your product.
