MakersLAB.TV S2E19 - Multi-Colour Screen Printing by Vinyl Applied Mesh on Carousel Screen Printer
Personalizing T-Shirts with a screen printer
On today’s episode Riley teaches us how to do multi-colour screen printing.
If you are printing multiple colours, you will need a way to separate the colours from each other so you can create different screens for your design. You need one colour per screen.
As soon as you have prepared your image on the vinyl, it is time to make the screen. A screen-printing frame consists of a wood or aluminium frame stretched with polyester mesh on it. The mesh holds the image onto the screen and let’s ink pass through when you press it with a squeegee.
You will need to coat the mesh with emulsion in order to expose the design onto the screen.
Before you coat the mesh with ink ensure that it is clean and has no dust or particles on it.
Set up the screens on your screen printing press.
A screen-printing press consists of a base that holds printing platen’s and a number of colour arms.
The advantage of having a higher amount of printing stations is that you can print faster.
Right before you clamp your screens into your press, you need to tape off the edges of your frame with screen printing tape. This helps keep ink from getting into places you don’t want it to.
Load your shirt onto the platen.
Load your shirt onto the press and get your printhead aligned.
Flood the screen with ink.
Once the print head is locked down, push or pull the screen printing ink across the screen to deposit the ink onto the shirt.
You may need more than one round of this depending on how much ink was deposited. If you are printing multiple colours, follow these steps with your other screens.
Cure the ink on your shirt with a dryer.
