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, non-textured paper towel behind
the transfer sheet to absorb the moisture.
