Causes of Sublimation Print Fading and solution：

The greatest method for printing on textiles and other materials is sublimation printing. Although it is strong and long-lasting, if improper care is not taken, the sublimation print fades soon.

The most frequent reason for fading is being exposed to light. The sublimation inks can occasionally fade as a result of poor handling and storage.

How to Prevent
Utilize the advice below to prevent fading: Keep your prints in a box or bag that is tightly closed. When not in use, wrap them in paper, tissue, or plastic.
Keep the prints away from bright light. Never put them in the freezer or fridge. Try to avoid letting your prints touch one another when storing them.
Keep them away from heat and harsh light if at all feasible. You should not clean your sublimation prints with common home cleaners like bleach, alcohol, or ammonia.
