How to Make a Screen Printing Stencil with Emulsion 

Thats awesome! Glad to hear that.

It really depends on your budget. Epson is the staple iconic inkjet printer but there are people out there using Canon, HP, etc. Look to see what size media you want to be able to print and go from there.

Check: - that the emulsion did not cure while drying, this is a light safe issue - the emulsion is not expired, could point to product/shelf stability issue (check manufacturers notes) Try washing a screen out after it has dried, but before exposing it, I know it sounds like a waste. But this is a dead giveaway if it’s a product issue or exposure issue. - the emulsion wasn’t mixed properly with an activator, scrape all sides and bottom, constantly folding. - exposure times, too much exposure can cure through the black ink of your film. - poor quality printer ink or film, this could mean the ink is not opaque enough on the film or the film is not holding enough ink (try 2 layers of film) - light source is too powerful, try exposing for far less time - the screen is being exposed on the opposite side, try placing non-reflective, black cardstock or a blanket on the opposite side of the screen to reduce reflected light curing the opposite side of your screen More often than not it’s just expired emulsion or user error and does not usually require equipment replacement. Let me know if I have to clarify anything!

All really good tips. The majority of the time it does come down to user error. Keep in mind that our ready to use emulsions have a shelf life of around 12 months if you store them properly. Thanks for jumping in and helping out.

That would be a registration template. It helps you light up your artwork to your screen so you get consistent results.

We recommend using a proper UV light for getting accurate exposure times.

Thats a really good question! So yes and no, there are different light wave lengths so certain UV black lights that make colors glow or fluorescent under them are not the proper wavelength to cure emulsion.

This is a Canon Pixma. They seem to be much more affordable than Epson printers. There are different sub model so you would have to check which fits your budget.

@@screenprintdirect Thank you I appreciate it

Great question, for this emulsion and with that light you are looking at an exposure time of around 30 seconds

@@screenprintdirect if I were to use sunlight, how long do you think I would need to expose it?

dejanos saber si tienes algun pregunta

the unit used would be the Screen Print Direct UV LED lamp link below! rb.gy/mt5sye
