What screen printing is and how it has evolved in the graphic industry

Screen printing is a printing method based on the use of a mesh stretched over a frame, which allows ink to be transferred onto a surface by applying pressure. It is a technique used in various sectors, but it has found one of its main fields of application in physical advertising.

Origins and evolution of screen printing

The earliest records of screen printing date back to ancient China, where silk stencils were used to reproduce patterns on paper and fabrics. Later, this method was adopted by other civilisations, such as Japan, which perfected the technique by incorporating more resistant and precise materials.

During the 20th century, with the development of photosensitive emulsion and process automation, screen printing became established as one of the most widely used printing techniques in the graphic industry. Today, screen printing has evolved with the incorporation of new technologies, such as UV inks and hybrid processes that combine digital printing with screen printing.

What is screen printing like in the graphic industry?

Today, screen printing remains one of the most widely used printing techniques in the production of physical advertising. Its ability to generate resistant, high-quality prints in different formats makes it an essential tool for manufacturing posters, signs, banners and signage.

In addition, screen printing is characterised by its ability to print on difficult materials, such as acrylic, metal, glass or wood, which sets it apart from other more conventional printing methods.

Basic principles and essential materials in screen printing

To understand what screen printing is like, it is essential to know the basic principles that govern this process and the essential materials used to achieve a quality print.

The screen printing process

The screen printing process is based on the selective transfer of ink through a mesh stretched over a frame. This mesh has blocked areas and open areas, allowing the ink to pass only through the desired zones to form the image on the surface to be printed.

The main steps of the process are:

  • Design preparation: A film positive is created with the image to be printed.
  • Emulsion application: The photosensitive emulsion is spread over the screen printing mesh.
  • Exposure to UV light: The film positive is placed on the mesh and exposed to ultraviolet light to harden the areas that should not transfer ink.
  • Cleaning and developing: The non-hardened parts of the emulsion are removed, leaving the mesh ready for printing.
  • Printing: Ink is placed on the mesh and a squeegee is used to transfer it to the desired surface.
  • Drying: The print is left to dry or cured using a drying oven if special inks are used.

Essential materials in screen printing

To achieve a quality print, it is essential to have the right materials. Among the most important are:

  • Screen printing frame: Usually made of aluminium or wood, with a stretched polyester mesh.
  • Photosensitive emulsion: A chemical product that allows the printing stencil to be created.
  • Screen printing ink: It can be solvent-based, UV ink or plastisol ink (for textiles).
  • Squeegee or scraper: Rubber tool used to distribute ink evenly.
  • Dryer or curing tunnel: Essential for fixing the ink and ensuring its durability.

Each of these elements plays a key role in the production of high-quality screen prints.

Screen printing techniques applied to physical advertising

In the field of advertising, screen printing is one of the most widely used techniques for the production of promotional graphic material. Its ability to print on different materials makes it ideal for advertising campaigns that require high durability and instant impact.

Types of screen printing

There are several screen printing techniques used in the production of physical advertising. Among the most notable are:

  • Flat screen printing: Used to print posters, adhesive vinyls, banners and promotional displays.
  • Cylindrical screen printing: Applied to the printing of curved objects, such as bottles, glasses or advertising packaging.
  • UV screen printing: Allows printing with inks cured by ultraviolet light, ensuring greater durability and weather resistance.

Each of these techniques has specific applications within the advertising sector and allows customised products to be created with excellent quality.

Applications in advertising

Screen printing is widely used in the production of advertising graphic elements such as:

  • Advertising posters for events and promotional campaigns.
  • Corporate signage in offices and commercial spaces.
  • Large-format signs for façades and shop windows.
  • Point-of-sale displays (POS) used in supermarkets and shops.

Thanks to its versatility and durability, screen printing remains one of the most widely used options in the advertising industry for the production of graphic elements.

Advantages of screen printing used in posters and physical advertising

Screen printing has established itself as one of the most effective techniques in the production of advertising material thanks to its versatility, durability and print quality. Compared with other printing methods, it offers significant advantages that make it the preferred option for posters, signs and signage. What is screen printing like? We explain it to you.

High resistance and durability

One of the main benefits of screen printing is the resistance of prints over time and to adverse weather conditions. Thanks to the application of special inks, printed designs can withstand exposure to sunlight, humidity and abrasion without losing quality or colour intensity.

In outdoor advertising, where exposure to the elements is constant, screen printing guarantees a long service life compared with other techniques such as conventional digital printing.

Adaptability to different materials

Screen printing allows printing on a wide range of surfaces, making it ideal for multiple applications in physical advertising. It can be applied to materials such as:

  • PVC and vinyl: Used in posters and lettering.
  • Acrylic and polycarbonate: Common in corporate signage.
  • Metal and aluminium: For plates and industrial signs.
  • Wood: Used in displays and customised decorations.
  • Textiles: In the production of advertising flags and promotional banners.

This versatility is key for companies looking for customised graphic solutions for their marketing campaigns.

Vibrant colours and high opacity

Unlike other printing systems, screen printing allows thick layers of ink to be applied, achieving intense and opaque colours, even on dark or transparent surfaces. This is especially useful in advertising, where visibility and visual impact are decisive factors.

In addition, the use of fluorescent, metallic and special-effect inks adds extra value to designs, allowing them to stand out from other graphic elements in commercial and urban environments.

Differences between screen printing and other printing techniques

In the graphic industry there are several printing techniques, each with its own characteristics and applications. If you have wondered what screen printing is and how it differs from other options such as digital and offset printing, mainly in terms of durability, costs and versatility, we explain it in detail.

Screen printing vs. digital printing

Characteristics Screen Printing Digital Printing
Durability High, ideal for outdoors Medium, more sensitive to weather
Materials Can be applied to multiple surfaces Limited to paper and vinyl
Cost in large volumes Economical for large print runs More expensive for large productions
Colour quality More intense and opaque colours Less saturation and shine
Production speed Slow in small quantities Fast for individual jobs

Digital printing is more suitable for projects that require speed and customisation in low quantities, while screen printing is ideal for mass productions with high requirements for resistance and quality.

Screen printing vs. offset printing

Offset is a traditional technique used mainly for printing on paper and cardboard. Unlike screen printing, offset does not allow printing on rigid materials or the application of thick layers of ink.

Another key difference is that screen printing does not require expensive printing plates, making it more accessible for medium and large print runs without compromising quality.

What is textile screen printing?

To understand what textile screen printing is, we need to understand that it is a variant of traditional screen printing adapted to print on fabrics. It uses specific inks that penetrate the fibres of the fabric, ensuring that the print withstands washing and wear without losing quality or colour intensity.

This process is ideal for large production volumes, as it makes it possible to obtain high-quality results at a reduced cost per unit. It is the preferred technique for many companies that need to distribute promotional clothing at events, trade fairs and advertising campaigns.
