This blog is about preparing your screen and coating it with photo emulsion prior to exposure.
Making great screens isn't rocket science, or expensive.
Getting great results and perfect prints comes down to following procedures, proper preparation, set up and limiting variables.
Have all the right equipment and materials ready to use. Do procedures in the right order and everything will come together.
Preparing and coating screens.
A smooth blemish free emulsion coating makes for much easier exposure and wash out. Details will hold better and prints will be sharper as the coating will be more even.
If you are having problems with your Photo Emulsion such as it not coating well on the screen, fish eyes and blemishes in the coat then it is most likely a poorly prepared screen.
Degreasing your screen is really important!
A clean degreased screen means the emulsion will adhere to the mesh better.
New screens must be degreased as well.
This means it will not break down as easily and ultimately last longer. Using a Mesh Prep / Degrease before you start is the answer. Mesh Prep will remove any grease, dust and dirt that may be on the screen. Its surprising how dirty the cleanest looking screen can be!
Use a soft sponge and a bit of mesh prep and wipe it all over both sides of the screen.
Rinse off really well.
When you think you have washed off all the degreaser, rinse it again until there's no bubbles. Do this on both sides as the degreaser / mesh prep gets right in the mesh particularly around the staples and corners.
Let it dry in a clean dust free place. The same place you are going to leave it to dry once its coated is perfect. It must be fully dry before you coat it, so be patient. Do not be tempted to dry it with a fan or hair drier. This will recover it with dust.
Top tip: Water this degreaser down a bit. Its very concentrated. You can go 2:1 with water but keep it full strength if screens are dirty.
