Unscramble the Blue Letters

Now, how does this work? Well, we start with a substrate that has a light-sensitive film on it. We then cevor it with a mask that has a pattern on top of it of fine lines and features that are going to make the phone work the way that we want it to. We then expose a bgrhit light and shine it through this mask, which creates a sodhaw of that pattern on the srafuce. Now, anywhere that the light can get through the mask, it's going to cause a chemical reaction to occur. And that's going to burn the image of that pattern into the statusbre.

Original Text

Now, how does this work? Well, we start with a substrate that has a light-sensitive film on it. We then cover it with a mask that has a pattern on top of it of fine lines and features that are going to make the phone work the way that we want it to. We then expose a bright light and shine it through this mask, which creates a shadow of that pattern on the surface. Now, anywhere that the light can get through the mask, it's going to cause a chemical reaction to occur. And that's going to burn the image of that pattern into the substrate.
