Screen Printing

Are you planning to get your business cards or letterheads printed or perhaps looking for a banners birmingham company to print your sales promotional banners? The traditional letterpress is outdated and you will find a hard time finding a company that offers printing via that method. Moreover, even if you did, the size of the printed material would be restricted to A4, as that is the approximate limit for such manual printers. However, you should not let this fact bother you as you have many other printing options to choose from such as offset, rotragravure, digital, and silk screen for your business printing services. The last method is the best as it allows deposition of maximum density of ink on the printed material, ensuring that they last for a long time. In addition, one can opt for this process to print on a wide variety and shape of materials, such as banners, tshirts, coffee mugs, pens, apart from business cards and letterheads.

What is screen printing?

This is a special method of printing in which the printer employs a special fabric, fixed on a frame containing hinges that allows the printer to lift it up and lower it, and containing the image to be printed on it. The remaining area is covered with a special chemical mixture that does not permit ink to permeate through it. Typically, the printer first coats the fabric with a light sensitive chemical compound, places a transparent film containing the image to be printed on it, and exposes the film to a bright light source (typically sunlight or a powerful halogen lamp).

As the light passes through the transparent areas of the ink, it causes an oxidation reaction on the chemical compound background. After this, the printer uses another chemical to wash the cloth. This process removes the oxidized chemical, allowing ink to flow through it. He then places the material to be printed directly under the frame, pours ink on one side of the frame, lowers the frame, and pulls the ink to the other side with a squeegee. This causes the ink to be deposited on the material underneath, completing the printing process.

Who needs screen printing?

Printers need this process for printing on materials as diverse as paper, fabric, ceramic, glass, and even metal. The quality of printing depends on the DPI (dots per inch) the fabric contains. For high resolution printing, the printer uses cloth containing a minimum of 150 dots per inch. He can repeat the process multiple times for printing images and text of different colours on the object.
