This step is very important. Without this step there is nothing u can do. So i’ll shows u all everything i know. All my secret that i myself learn from somebody else – my guru.

First thing you need is film negative.

Image that u print black on a plain paper.

Exposure Table.

500w light (set 35cm from the glass) and a transparent glass.

Put the image on the exposure table.

Adjust it to ur needs.

The secret : Budget savings.

Uses cooking oil to turn the image’s paper into

hand made tracing paper.

Spread the cooking oil evenly.

Put the Printing Block (first step) onto the image.

Adjust to ur needs.

Put a black paper into the printing block.

Put any flat surface object onto the black paper.

I use plywood.

Put on a weight onto the plywood.

After that, Swicth On the spot light.

I use two spot light. Let it expose for 3 minutes.

After 3 minutes. Spray it with tab water.

Wash it untill the image is shown.

Lastly leave the block to dry.

Finished.

Exposure Concept :

The image will block the ligth to reach the photo coat mesh.
Because its make shadow on it.The other parts are expose to light directly. Its will become hardened.
Because the photo emulsion is water-based, its will dissolve when wash by a tab’s water.
The shadowed part will dissolve and the hardened part will not affected.
That why u get the finall picture above. u can see through the mesh.

Tips of the day :

We use the cooking oil – cost effective.
It’s important to adjust the image to be centre at the printing block. So when u want to print it manually, it’s easy to print the image “centre” on ur tshirt.
Black paper – to absorb the ligth without reflecting the light back to the image from the top of printing block.
Plywood – to make the screen mesh touch the image below evenly when put a weight on it.

Enjoy! and see u all next time.
