If you are doing sublimation printing, you will know that moisture is an important factor which can influence your normal work. As a sublimation paper supplier, when our customers want us to recommend a suitable paper for them, the first factor we consider is the printing environment, especially the moisture. Then, how does moisture influence the sublimation printing?
If everything checks out, moisture may play a role in spotty transfers. Moisture can warp flat items and can act as a barrier between the surface and the sublimation ink trying to penetrate it. This step is not always listed on the instructions, but it is good practice to pre-press items for 5-10 seconds at high heat and light-medium pressure to let moisture escape and flatten out the substrate. For warped items, such as MDF boards, pre-pressing both sides may be necessary.
If you don’t want to be influenced by the moisture, please let your sublimation paper and other materials keep dry.
