Yellow Stamps?  Here's what it means...

If you are new to the stamping world, you might be wondering what photopolymer stamps are.  So, let's answer that question first.  Photopolymer stamps are stamps created with polymer and UV light,  Raised lines in the polymer creates the designs/images that can then be inked up and stamped onto paper. 

 

Since photopolymer stamps are created with light, if they are stored in direct sunlight or UV light, they will tend to turn yellow.

​

However, the good news is that just like ink staining on clear stamps, yellowing of stamps will not affect the stamped image.  If you are using a good quality stamp, that stamp with proper care, will last for years if not decades.  

 

To care for photopolymer stamps, simply clean after use with a stamp cleaner or soap and water and store away from direct sunlight.
