MOISTURE & HUMIDITY PROBLEMS
The addition of moisture to the sublimation process can cause unwanted results. Under normal circumstances, the small amount of moisture that can accumulate in your paper is absorbed directly into the transfer substrate; however hard substrates like metal and ceramic are unable to absorb excess moisture. Some of problems that are attributed to moisture include: color shifting (colors lose accuracy), bleeding of the image, and uneven transfer of solid filled areas
To avoid these problems
Keep your paper in a dry place.
If you suspect moisture, set the paper on your press for a few seconds. Do not press it. Just expose it to the warmth. The heat radiating from the press should help evaporate most of the moisture.
To eliminate moisture in fabric, press the fabric for 10 seconds before doing the heat transfer.
Use an absorbent cloth or fresh,
