Also known as clear acrylic stamps, photopolymer stamps or polymer stamps are made up of photopolymer material. These stamps are higher in quality as compared to acrylic stamps. If you have been using rubber stamps, cling stamps, and acrylic stamps for a while, and have just started using a photopolymer stamp set, you would agree that it is life-changing. Essentially, this stamp is used to transfer a design or an image onto a surface, using inks (dye inks, pigment inks, etc.). Because of this stamp’s sticky nature, the ink sticks very well to the stamp’s design, therefore resulting in a crisp stamped image.

How Do You Use Photopolymer Stamps?

If you aren’t new to stamping, you already know the whole process and the basics. Similar to acrylic stamps, using photopolymer clear stamps is pretty much straightforward. They are super easy to use that even your kids can figure them out. 

Here are 6 easy steps on how to use photopolymer stamps:

  1. Condition the stamp with a stamp conditioning eraser or a watermark/embossing ink, especially if they are new. (Read more on stamp conditioning below!) 
  2. Peel back the stamp’s acetate backing sheet.
  3. Peel the stamp from the clear acetate liner. 
  4. Place it onto a clear acrylic stamping block. Since it will quickly cling to it, there is no need to use any kind of additional adhesive or a cushion. 
  5. Press it firmly onto the acrylic stamping block to ensure that it is well-adhered. 
  6. Next, simply ink it up with your chosen ink and stamp away!

Piece of cake, right? Once you get the hang of it, you can stamp with your photopolymer stamp set even with your eyes closed.  

The video below will show you a quick and easy tutorial on how to use DIY photopolymer stamps in card making.

What Is Stamp Conditioning and How Do You Condition Clear Stamps? 

Do you want to avoid blotchy stamped images? Are you tired of your stamp sticking too much to your cardstock or paper? Do you want to get clean and crisp stamped images every single time? The most important thing you have to remember when using clear stamps is that you need to condition them.

Here are some tools that you can use to prepare or condition your stamps:

  1. Use a clear watermark ink or embossing ink.
  2. Use a rubber eraser.
  3. Use your fingers. Yes, you can use your fingers if you find yourself without an embossing ink or a rubber eraser. Simply rub the sticky part of the photopolymer clear stamp using your finger. It’s as simple as that.  
  4. Use alcohol prep pads. You can use these to clean up any rubber eraser residue.
  5. Use a stamp cleaner. This is a handy tool to have since it is designed to clean stamps better than anything else - especially when you have no access to clean water and soap. 
  6. Use a stamp shammy. This is basically a piece of cloth that you need to soak with water.

New photopolymer stamp sets are sometimes too sticky and shiny. The stickiness is both a good thing and a bad thing; it allows it to stick well to an acrylic block or a stamping platform, but it also prevents the ink from sticking to it. This is due to the fact that clear stamps are made using a resist method. The chemicals that cause that “resist” will create that stickiness. The same chemicals will also resist ink. Conditioning your stamp will give you a clean, crisp, and smooth stamped image and get rid of the unwanted lumps, fiber, dust, or other strands.

How to Clean Photopolymer Stamps?

Now that you know how to use photopolymer stamps, it’s also essential to learn the process of cleaning photopolymer stamps. Even beginner stampers should know that stamps must be cleaned every after use. Not cleaning them afterward will affect their quality and might permanently stain them.

Here are a few stamp cleaning tools that you can use:

  • Water
  • Mild soap
  • Clean cloth
  • Stamp cleaner
  • Stamp shammy
  • Baby wipes or wet wipes (not highly recommended since there are instances where it would leave fibers onto your stamps)
