Equipment you'll need in print.

PAPER - It makes sense to practise printing on paper first, so if you mess up your not wasting a shirt, and you can see if you need to make amendmants to your design. For the best results on paper you should put a penny or some cardboard  between your screen and the paper so only the design is printed.

APRON/OLD SHIRT - Now unless your Mr.Miyagi, I suggest you get yourself either an apron or a shirt you dont care about, because it can get messy. Not to mention the paint you should be using, will stain.

T-SHIRT - This will become the proud flag of your art. Although anything can be used to print on, the printable objects are called substrates.

SCREEN PRINTING MEDIUM - Its best to use different paints for different surfaces, for instance you should use water or oil based inc for paper, fabric inc for fabric. The all round savior would be acrylic, Its what we used for our shirts and paper so I assume its an all rounder.

SQUEEGEE - It is whats used to drag the ink across the screen evenly. You will need a squeegee to also administer the emulsion to the screen after washing it of coarse. 

 
SCREEN - You apply the emulsion to the screen which seeps into the mesh. On the other side of the screen you place the image which you want burned and used. The mesh on the screen are like pixels, the smaller the holes the clearer and less jagged your picture will be.

PALLET KNIFE - Used for mixing acrillic paints and to scoop out emulsion to then place onto a scoop. It has a flexible, durable steel blade which makes it have more movement and therefore easier to use on thick liquids.
PHOTOSENSITIVE EMULSION - The reason we use photosensitive emulsion is because its so sensitive to light, when its exposed to light it hardens, so if we coat the screen with the emulsion it seeps through the screen filling the tiny holes, on the other side of the mesh we put our image, so when the light hits the emulsion it hardens with the shape of your image burned into it. We then wash off the rest of the emulsion to have a screen with your image ready.


LIGHTBOX -  When the screen is covered in the emulsion, the UV rays harden it. If you put any black screen infront of any part of the emulsion, it will not set what you've covered up and therefor will be able to get washed off with water.
