We recently received a technical support inquiry into troubleshooting bad results when sublimating mugs. Our customer was getting faded, blurry images and we obviously worked with them individually to get their mugs looking beautiful and vibrant. So, what do YOU do if you start getting less than desirable outcomes?
Here’s a quick checklist for you to review:
- If you’re just getting yellow shading on the mug, there’s a good chance you’re actually using inkjet ink, NOT sublimation ink (which is required to sublimate onto mugs).
- Make sure you’re using the correct time and temperature for your mug press. Most mug presses will require different times and temperatures for pressing mugs (and water bottles, steins, etc.). Our Mug Master Pro actually has an idle temperature which is lower than the actual pressing temperature, allowing the mug to heat up with the mug press. Here’s a list of drinkware pressing instructions for the two mug presses we currently carry (and one that we used to carry).
- If it appears the image is blurry, there’s a chance you may be over-pressing the mug, meaning the ink is gassing out and spreading over more area than it should. You can also tell if you’re over-pressing the mug if the black colors appear brown-ish.
- If the black colors in your image appear green-ish after pressing, it usually means you’re under-pressing the mug.
- Use an ICC profile or PowerDriver when printing with Sawgrass inks in order to get the best color out of your sublimation ink.
- The quality of the image on the mug may be poor because the actual image quality is poor. We suggest a DPI of 300 for sublimation printing. Not sure what that means? Here’s a great blog that will help you understand the difference between a good image and a bad images.
