How to exposure your own screens at home:

Step 1: 

Mix emulsion

You'll need to activate your emulsion before coating your screen. To do this, Fill the small diazo-sensitiser bottle with room temp water (from the tap is fine), screw the cap on tightly and shake. Once shaken, Pour the liquid into your emulsion tub and stir until completely mixed. Let it settle for 2 hours once mixed to elminate any air bubbles. Make sure the lid is re-applied during this time to prevent light from getting to it. 

Step 2:

Coat and dry screen

Put some of your mixed emulsion into the well of your emulsion coater and coat your screen both sides. Follow this video for instructions on how to do this: How to coat a screen using a scoop coater

as this is a polymere based emulsion, It's best to do this is a low light area - Out of direct sunlight to prevent early exposure. 

once coated, Leave to dry for 24hrs in a dark area such as a cupboard or airing cupboard. IMPORTANT TIP: Leave your screen facing print side up (the well of the screen facing upwards). This prevents any drips forming on the print side of your screen which causes an uneven surface when it comes to printing

Step 3

Print your artwork 

Whilst your screen is drying, print your artwork using the film provided. This can be done on an inkjet printer using black cartridges. The more opaque the design, the better the final exposed screen. 

Step 4

Expose your screen

Now your screen is coated and dry, You're ready to exposure.

Fit your bulb into a lamp (We recommend a desk lamp as it can be angled over the top of your screen). For good exposure, it needs to be at a height of 12-15" above your screen. (the higher the bulb is, the longer your exposure time - The lower your bulb is, the more risk of missing some of your design depending on the size of your design). We recommend starting with an exposure time of 10 - 12 minutes although the kit does also have an exposure calculator to test your exposure times. You simply expose your screen with the exposure calculator film like you would with you design, And once exposed and washed out, It should be able to tell you whether to decrease or increase exposure time from the gauge. 

Step 5

Wash your exposed design 

Using a hose (we recommend a high pressured washer as it's much quicker), Wash your screen. Your exposed design should wash out easily. If it doesnt, your screen is over exposed. If all our your emulsion on your screen starts to break down or feels slimey, Then your screen is under exposed. If thats the case, you'll need to re-do the process again from the begining.
