Many users have had great success with sublimation; they have achieved consistent results every time. The images are bright, vivid, and match the colors that they have desired. A few users have had some problems with their images and here are some of the most common mistakes made when using sublimation. We have duplicated mistakes purposely so that you can compare with our results!
Nozzle Check problems
If the color of your image is off. For example, if your image has a red tint, or other color tints, there’s a high chance that it is because your nozzles are not firing properly in your sublimation printer.
At the beginning of the day, I always print a nozzle check before I start any jobs as this will ensure that all nozzles are firing. We suggest daily nozzle checks to prevent virtually all clogs.
Here’s a comparison between a perfect nozzle check and one that isn’t.
Here is a comparison between a print with a perfect nozzle check and one that has a nozzle check problem.
Fixing this problem is very simple. If your nozzle check isn’t perfect, just clean your nozzle head through your OEM printer driver or through the power driver that you downloaded. And then, perform another nozzle check. Sometimes it may require more than one head clean to clear the clog.
Check to make sure you are using sublimation paper.
Sublimation requires special sublimation paper for the sublimation inks to release properly when heated. It is easy to mix up sublimation paper with normal paper as they are both white and feel very similar to one another. Most standard sublimation papers are only coated on one side (however there are some that are coated on both sides). You can compare the two sides of the paper to tell sublimation paper and plain paper apart. The coated side is usually brighter than the uncoated side. With plain papers, both sides will be the same brightness.
Printing on the wrong side of the paper
You may be printing on the wrong side of the paper. As stated above, the coated side of the sublimation paper is brighter than the uncoated side. So be sure to print on the brighter side
If you are printing on the wrong side of the paper, you will get the same result as when you use plain paper.
Follow the instructions for your product
Most imprintable blanks will come with their own instructions. Please follow them carefully. Each type of blank may have a different set of instructions. If unsure, please confirm the instructions with your vendor.
As you can see images using too much heat turns the image a bit brown and in some cases the image and text on it will appear pixilated. And images with insufficient heat will appear faded.
Using the wrong inks
Sublimation is an easy to learn method to print onto a variety of substrates including 100% polyester clothing, bags, ceramic mugs, tiles, plaques, etc. But the instructions have to be followed accurately to achieve consistent results. Also the setup of your sublimation printer has to be correct. Sawgrass (A Manufacturer of sublimation inks) has posted excellent videos of how to setup your sublimation printers. Here are some useful links below for your reference.
