Let us continue further and answer your doubts to ensure your heat transfer printing order at Custom One Online offers you the expected results. 

History of Heat Transfer Printing:

As soon as polyester became the new favorite fabric, there was a need for a more effective and quality-oriented printing technique and thus heat transfer printing was first invented. The process was very intricate and printed patterns on the paper with some selective dyes. The paper, also known as the design stencil, is then placed on the fabric and the design is finally transferred to the fabric. 

In the beginning, the use of heat transfer printing was limited to novelty items only. People orders polyester tops and t-shirts and the results were commendable. The practice has today evolved significantly and now the technique is one of the prime printing tech used by textile and manufacturing industries. 

The Process Steps of Heat Transfer Printing:

If you want to transfer your custom logos or designs on the apparel beautifully, choosing heat transfer printing is an excellent method. The process of transferring the print to a paper and then from the paper to the fabric is exemplary. There are different ways to perform the heat transfer process including inkjet transfers, dye sublimation transfers, digital appliqué transfers, and vinyl transfers. There are several steps involved in each one of the processes and in this section, we will discuss each one of these steps in detail. 

1- Gather the necessary supplies

You will need a handful of items as well as advanced machinery for effective heat transfer printing. Some core supplies required during the procedure include:

  • Computer
  • Printer 
  • Ink
  • Heat Transfer Paper
  • Cutter
  • Heat Press
  • Heat Pads
  • Heat tape
  • Heat resistant sheeting 
  • Substrates & more

The second step of the process is to create the design. At Custom One Online we offer you choices to choose a template, submit your own designs or create a design with the help of a pro designer from our team. 

3- Printing the design 

The final design is then printed on a special heat transfer paper for further process. We use three different types of ink including inkjet ink, pigment ink, or sublimation ink and the selection is made based on the product and application. 

4- Cutting the design 

In this step, the design is cut using a vinyl trimmer. However, this step is not used in all processes. 

5- Warming up the heat press

Warming the heat press is a critical step and must be done very efficiently. E press is first opened and the heat platen is removed from the heat pad. The heat platen and pad are placed open as it warms up. Usually, the ideal templates for the heat transfer printing process is between 350-375F.

6- Adjusting the pressure

Depending upon the thickness of the fabric, the pressure of the press is adjusted. If the fabric is thicker, it needs lesser pressure. In most cases, medium or high pressure is used on different types of fabrics. 

7- Setting the time

Depending upon the type of the heat transfer process, the rime caries significantly. The common time guide is as follows:

  • For Inkjet Transfer Paper the timing is 14-18 seconds.
  • For Dye Sublimation Transfer the timing is 25-30 seconds.
  • For Digital Applique Transfer the timing is 20-30 seconds.
  • For Vinyl Transfer the timing is 45-60 seconds. 
8- Setting the substrate and transferring in place

The product is now positioned on the plate and the design paper is placed on the right location at the pressing area. In the case of Vinyl transfer, the paper is covered with a thin cloth to protect the design. 

9- Pressing the product

As your pressing machine is fully set by this time, you can now pull the handle or press the start button to press the design against the fabric.  

10- Removing the film

There is a timer on the press, wait for it to go off and then open the press. Now remove the film. At this time your transfer paper will be hot and the design will be transferred onto the [product, just like you wanted it to be.
