Sublimation Printing on Ceramic Mugs: The Basics

Sublimation Printing on Ceramic Mugs blog post

Sublimation printing is a popular method for personalizing and customizing ceramic mugs. This process involves using heat and pressure to transfer dye onto the surface of a ceramic mug. The result is a vibrant and long-lasting image that is both dishwasher and microwave safe.

What is Sublimation Printing?

Sublimation printing is a digital printing process that uses heat to transfer dye onto a variety of materials, including ceramic mugs. But not just any mug, as the process will only work with a polyester coated mug. The process begins by printing a design onto sublimation paper using specialized CMYK sublimation dyes (not inks believe it or not!) The sublimation paper is then wrapped around the ceramic mug and either placed directly into a clam-shell heat press or it is wrapped with a silicone sleeve (for pressure) and put inside a convection oven. The heat and pressure from the mug press or silicone wrap causes the dye to transform into a gas, which then permeates the polyester coating on the mug's surface and solidifies into the design.

Materials Needed for Sublimation Printing on Ceramic Mugs

Preparing the Ceramic Mug for Printing

Before starting the sublimation process, it is important to properly prepare the ceramic mug. This includes cleaning the mug thoroughly to remove any dust or debris, as well as ensuring that the surface of the mug is smooth and even. Any imperfections on the surface of the mug can affect the quality of the final print. Some have a air compressor setup close by to give the mug a quick burst of air to make sure there are no dust or any other debris (some fabrics can actually sublimate into the image if not wiped off prior!)

Designing for Sublimation Printing

When designing for sublimation printing, it is important to keep in mind the unique properties of the ceramic material. The design should be created at a high resolution and can be either CMYK or RGB color format. It is also important to note that sublimation printing can only reproduce a limited range of colors, so it is important to keep designs simple and avoid the use of very small text or detailed graphics. There is no white available to you since you are actually dying the surface of the mug. Any white used in your design with not actually have dye on the transfer paper once printed. Since the mug is white, it comes through as the design intended.

Setting up the Heat Press

The heat press is a crucial component in the sublimation printing process. It is important to properly set the temperature and pressure on the heat press to ensure the best possible print. Generally, the temperature is set between 400-420 degrees Fahrenheit and the pressure is set to medium. Time can vary on product and other factors. This can vary greatly with different materials. If you change paper, printers, presses, etc, you'll want to make sure your settings haven't been compromised. The correct time and temperature "recipe" can be difficult to achieve at first. Trial and error is the name of the game here.

Sublimation Printing Process

  1. Print the design onto sublimation paper using a sublimation printer.
  2. Wrap the sublimation paper around the ceramic mug, ensuring proper alignment and affix with heat tape.
  3. Place the mug and paper into the clamshell heat press.
  4. Set the heat press to the appropriate temperature and pressure.
  5. Press the mug for the recommended time which can vary greatly - see your manufacturer's recommended settings and adjust from there.
  6. Remove the mug from the heat press and allow it to cool. Typically the handle will be cool enough to touch, but a heat glove is recommended.

Caring for Sublimation Printed Ceramic Mugs

To ensure the longevity of the print, it is important to properly care for the ceramic mug. This includes avoiding the use of abrasive cleaning products and not exposing the mug to extreme temperatures. Although technically the mug is microwave and dishwasher safe, it is typically recommended to hand wash the mug rather than placing it in the dishwasher.


Sublimation printing is a great option for personalizing and customizing ceramic mugs. It is a cost-effective and efficient method that produces high-quality, long-lasting prints. With the right materials and equipment, anyone can create beautiful and unique ceramic mugs for personal use or as a business opportunity.
