Understanding Ghosting on Sublimation Tumblers
Sublimation tumbler printing is a fascinating technique that involves printing high-quality digital images on specially-coated tumblers. This process is known for producing vibrant and long-lasting graphics that do not fade or flake away. However, as great as the sublimation tumbler printing process is, there is one issue that can make things go terribly wrong- ghosting.
Ghosting on sublimation tumblers can ruin an otherwise great product. Ghosting occurs when the image that is printed onto the tumbler appears faded or distorted. The distortion makes the image look as though there is a shadow or ghost of the original image that is visible.
There are many reasons why ghosting occurs. For instance, if you do not properly prepare the image that you are printing, this could cause ghosting. Similarly, if you do not use the correct settings on your sublimation printer, this too could result in ghosting. In most cases, ghosting occurs when the image is not correctly aligned when it is being printed on the tumbler.
Fortunately, there are numerous ways to fix ghosting on sublimation tumblers. In this article, we will discuss some of the most effective methods of resolving ghosting on sublimation tumblers.
However, before we delve into the solutions, let’s first look at what causes ghosting on sublimation tumblers.
One of the most common causes of ghosting on sublimation tumblers is printing an image that has a low resolution or quality. When you use an image that is low in resolution or quality, it will not appear as crisp and clear as high-resolution images. This can result in ghosting, especially if you are printing on a larger tumblers.
Another common reason for ghosting is using the incorrect heat and pressure settings. If the temperature is too high or the pressure is too low, this can cause ghosting because the image will not be transferred onto the tumbler correctly. It is important to use a heat press that is specifically designed for sublimation tumbler printing and to follow the manufacturer’s instructions carefully.
Moreover, the surface of the sublimation tumbler must also be prepared adequately to avoid ghosting. If the surface is not cleaned and coated with sublimation ink correctly, ghosting can occur. For instance, if you do not remove all the dust and dirt on the surface of the tumbler, the image will not be transferred evenly, which will cause ghosting.
In summary, there are several reasons why ghosting occurs on sublimation tumblers, but the good news is that it is not too difficult to fix. The key is to identify the cause of the problem and then take the steps to resolve it. In the next sections of this article, we will look at some practical solutions to fix ghosting on sublimation tumblers that you can easily follow for optimal results.
Identifying the Cause of Ghosting
If you are experiencing ghosting on your sublimation tumbler, the first step to fixing the problem is identifying its cause.

Also, ensure that the temperature is constant throughout the pressing time. If the temperature fluctuates, the image will not transfer properly, or the transfer may be incomplete, resulting in ghosting. Therefore, invest in a good quality heat press machine that maintains consistent temperature and pressure throughout the transfer process.
3. Dirty or Contaminated Surface
Any dirt, oil, or contamination on the surface of the tumbler will result in incomplete image transfer. Even the slightest trace of dirt could affect the quality of the image transfer. Therefore, ensure that you thoroughly clean the surface of the tumbler before attempting to sublimate it. A gentle detergent, an LCF cleaner, or rubbing alcohol are the most effective cleaning agents for sublimation tumblers. Ensure that you thoroughly clean the tumbler, let it dry, and handle it carefully to avoid introducing any dirt or contaminant.
4. Poor Quality Ink or Paper
A poor quality sublimation ink or paper is another common cause of ghosting on sublimation tumblers. Low-quality ink or paper may not transfer fully or accurately to the tumbler, resulting in sub-par image quality. Therefore, it is essential to invest in high-quality sublimation ink and paper. Also, ensure that the ink cartridges are properly aligned, and there are no clogs or air bubbles in the system. The paper should also be smooth and free of wrinkles or creases for the best transfer results.
5. Incorrect Dye-Sublimation Profile Settings
The dye-sublimation profile settings on your printer and software can also cause ghosting on sublimation tumblers. Incorrect settings, such as low resolution, low color density, poor contrast, or unaligned image, could result in a sub-par image transfer. Therefore, ensure that your printer and software settings match the substrate and transfer process. Also, make sure that your printer is equipped with a color management system that adjusts the color density to the tumbler’s surface and material.
By identifying the root cause of ghosting on your sublimation tumblers, you can apply the appropriate measures to fix the problem and produce high-quality and vibrant images on your tumblers.
