What is screen printing? How does it work?

What is screen printing? Screen printing has advanced from the ancient craft of stenciling that occurred in the last part of the 1800s. And after sometimes, with adjustments, the strategy has developed into an industry.

Screen printing overcame barriers between hand took care of production and automatic printing, which was absolutely more costly. It immediately changed from handcraft to large scale manufacturing, especially in the US. In doing so, screen printing opened up a new zone of print abilities and changed the advertising business.

Today it has become an extremely complex process, using modern textures and inks joined with computer innovation. Frequently screen printing is used as a substitute for different processes, for example, offset litho. As a printing method, it can print a picture onto any surface, for example, paper, card, wood, glass, plastic, calfskin, or any texture. The iPhone, solar cell, and the hydrogen power module are all screen printed items – and they would not exist without this printing method.

Production:

Screen printing is a procedure that includes using a woven work screen to help an ink blocked stencil to get an ideal picture.

The screen stencil structures open zones of mesh that move ink or other printable materials, by squeezing through the mesh as a sharp-edged picture onto a substrate (the item that will get the picture).

The squeegee is moved over the screen stencil, driving ink through the openings to wet the substrate throughout the time of squeegee stroke. As the screen bounces back away from the substrate, the ink remains. Fundamentally it is the way towards using a mesh-based stencil to apply ink onto a substrate, regardless of whether it is a shirt, banner, sticker, vinyl, wood, or different materials.

One reason that the screen printing method is so broadly used is that it produces distinctive colors, even on more obscure fabric. The ink or paint additionally lies in the outside of the fabric or paper, which results in a good material quality print.

Usage:

Screen Printing is most usually connected with T-Shirts, cords, inflatable’s, packs, and various products. Anyway, this method is additionally used while applying latex especially to print scratch cards or for a beautiful print measure called spot UV.

All using a similar cycle of squeegees and screens, the clear covering is then presented to UV radiation lights for the drying purpose. Principally used to improve logos or portray certain content, spot UV is an extraordinary method to take your print to a high level.

Step by Step printing process:

There are many strategies for screen printing, they all work on a similar basic technique. The kind of printing we’ll discuss uses an uncommon light-responsive emulsion to make a custom stencil; this will in general be the most famous sort of business printing, as it very well may be used to make complex and detailed stencils.

Here, we’ll talk about the screen printing method in detail.

Design creation:

To begin, the design is given to the printer which it needs to create on the product and prints it out onto a straightforward acetic film. It will be used to make the stencil.

The screen is prepared:

The printer will pick a working screen to suit the complication of the design and the surface of the cloth or poster which will be printed. The work screen is then covered with a layer of light-receptive emulsion, which will solidify when created under splendid light.

Creation of Stencil:

The sheet is then placed onto the emulsion-coated screen, and the entire thing is presented to vivid light. The light solidifies the emulsion, so the pieces of the screen which are secured by design stay in fluid structure.

If the design has more than one color, at that point a different screen must be used to apply each layer of ink. To make multi-color items, the printer must utilize his expertise to design each stencil, and line them up in perfection to guarantee that the final plan is seamless.

After the screen has been uncovered for a set time, the area of the screen, not secured by design, will have turned hard. An unhardened emulsion is then deliberately flushed away. This leaves a good impact on the screen for the ink to go through.

When the screen is dried, the printer will make any important final details or revisions to make the print as exact as the design is. The stencil is set up to be used.

The product is ready to be printed:

The screen is then positioned on the print machine. The thing or piece of clothing being printed is set down on the printing board, below the screen.

There are various presses, consisting of manual and automatic styles. Yet most present-day business printers will utilize an automatic rotational printer, as this permits many distinct screens to work without a moment’s delay. For printing multi-color products, such a printer can be used to apply the different shading layers with hardly a pause in between.

Checking and finalizing the product:

The printed item at that point goes through a dryer, which ‘fixes’ the ink and makes a smooth, colorfast finish. The final item will be checked and washed completely to eliminate any buildup, before being given to an owner.

Advantages:

  • Ease to set up and speed of pivot.
  • Simple to print in a scope of various colors.
  • Move photographic pictures precisely.
  • Prints can be altered in many ways.

Disadvantages:

  • The scope of printable fabric is more restricted to screen printing.
  • The print isn’t so solid.
  •  White color cannot be reproduced within the print.

 

Conclusion:

In this article, we have discussed in detail about Screen Printing and how it works. We have only discussed that screen printing is used to design clothes, it is also a very popular process of creating posters and many other artworks. So if you are a poster designer then screen printing will also help you to create different designs. Hope you will find this article effective.
