Know about how screen printing works!

The process of transferring a stencilled design using ink, a mesh screen, and a squeegee onto a flat surface is referred to as screen printing. Though paper and fabric are the most prevalent screen-printed surfaces used, one can make use of specialised inks to print on plastic, wood, metal, and glass. Creation of stencil on a fine mesh screen and later, pursuing ink or paint, if it is for craft and posters, is one of the primary methods involved in screen printing. So, let us quickly look at all the possible information about screen printing! What say?

Step-by-step process of screen printing!

Creation of design: To begin with, the printer receives the design we want to create on the finalised product and prints it onto a transparent acetate film. This will result in helping us to create a stencil.

Preparation of Screen: After the first step of receiving the design and printing the same, the printer chooses a mesh screen to match with the complexity of the design and the fabric’s texture being printed. When developed under bright light, it is coated with a layer of light-reactive emulsion to harden the mesh screen.

Exposure of emulsion: After the second step of the acetate sheet featuring the design, it is laid onto the screen coated by emulsion, and then the whole sheet is exposed to the brightest light ever. If the final design includes more than one colour, one should use a separate screen to apply each layer of ink.

Creation of stencil while the emulsion is washed off: After exposing the screen for a given amount of time, some areas not held with designs will turn hard. The unhardened part of the emulsion is rinsed away carefully, leaving a precise impression and print of the design on the screen so that the ink passes through successfully. After the screen gets dried, the printer will make necessary corrections and touch-ups, if needed, and now, the stencil is ready to be used!

Preparation of item to print: The garment or item that should be published is laid onto the printing board, while on the other hand, the screen is placed on the printing press. Also, for printing, there are various presses, such as manual and automatic styles.

Pressing the ink through the screen: The ink is added to the screen’s top-end as the screen is lowered down to the printing board. Along the entire screen length, the squeegee is used to pull the ink. This results in the pressing of the ink in the open areas of the stencil.

Drying, checking, and finishing the product: After the product is printed, it is subjected to pass through a dryer resulting in a curation of the ink and smoothening of the colourfast finishing!
