This issue may occur when using silicone-type plastic card holders.
Silicone-type card holders can absorb and retain heat during the printing process. When the printed card is placed inside the holder while it is still warm, the retained heat can cause the printed surface to soften and transfer onto the card holder.
For this reason, we do not recommend using silicone-type card holders with cards printed using direct-to-card printers.
Instead, we recommend using the following types of card holders:
These types of card holders are recommended to help minimize the risk of print transfer or damage to the printed surface.
