Screen Printing Ink with Additives: Understanding Ink Composition, Types & Applications

Screen printing is a widely used and well-established printing technique that entails several steps. It’s pretty adaptable, as it may be done on a variety of surfaces of various shapes and sizes. A traditional approach can be used to create this strategy. In many applications, Screen Printing Ink with Additives is also considered to enhance ink performance and achieve better results. Screen printing inks that are either available as one or two-component inks provide excellent color consistency and adhesion to various surfaces, making them suitable for a wide range of applications.

The Evolution of Screen Printing and Screen printing inks/paints/coatings

Screen printing is a centuries-old art form. Around 950 AD, an early form of the process was pioneered in China as a method of printing designs onto fabric. Several centuries later, Japanese artists used a stiff brush to force ink through a mesh screen woven from human hair to transfer designs onto paper and textiles.

Screen printing first appeared in Europe in the 18th century, but it was sluggish to gain popularity as a method of fabric printing due to the excessive expense of silk mesh at the time.

By the early twentieth century, printers had created photo-sensitized emulsions, allowing craftspeople to manufacture complicated stencil designs much more quickly.

Screen printing is now employed as both an artistic medium and a commercial printing method. Because a single stencil can be used to replicate the same pattern hundreds — if not thousands — of times, it’s an excellent method for generating huge printing impressions on the various substrates such as plastic, glass, leather, wood, garments, and many others.

How does Screen printing technology  work  ?

Screen printing is a type of direct printing that follows a set pattern. A blade and squeegee, a mesh (screen) made of synthetic polymers such as nylon and polyester is used to transfer the stenciled design onto the substrate and define the final image.

First, the printer prints the design on the final product onto a transparent acetate film. Then the printer will next select a mesh screen that is appropriate for the design’s intricacy and the substrate which is being printed.

He will print the design on the mesh and then the screen is placed on the printing press over the product that needs to be printed.

A squeegee is used to drag the ink along the whole screen length once it has been applied at the top end. After that, the printed object is dried, curing the ink and giving it a smooth, colorfast surface. Finally, before being passed on to its new owner, the completed product will be cleaned to eliminate any residue and properly examined.

Press for screen printing

While screen printing may be done with simply a mesh screen and a squeegee, most printers prefer to utilize a press since it allows them to print many things quickly. As the press keeps the screen in place between prints, it’s easier for the user to change the paper or clothes being printed.

Screen for screen printing (Silkscreen)

In silkscreen printing, silkscreen is a metal or wooden frame with a thin mesh cloth stretched across it. Traditionally, this mesh was made up of silk thread, but polyester textiles have replaced it, providing the same performance at a cheaper cost. The mesh may be customized in thickness and thread count to match the surface or printed fabric texture with smaller gaps between threads allowing more detail in print.

Squeegee

A squeegee is a long wooden, metal, or plastic handle with a rubber blade attached. It is used to force the ink through the mesh screen onto the printed surface. The printer will generally choose a squeegee of the same size as the screen frame, providing excellent coverage.

The Pigments (Inks)

The ink, pigment, or paint is forced through the mesh screen on the product that leaves a colored imprint of the stencil pattern on the product.

Selecting the ink is much more than simply picking a color. Several special inks may be employed to provide various effects on the completed product.

Screen Printing Ink with Additives: Understanding Ink Composition

Pigments – They make up between 5% and 30% of ink. Typically,  Pigments are finely shredded solid particles that are distributed in the binder rather than dissolved in it.   In most cases, a larger concentration of a certain pigment influences the intensity of its color. In practice, however, optimum doses of pigments are employed, above which no change in color is noticeable.

Binders  – comprises between 15% and 50% of the ink’s makeup Its purpose is to moist the pigment, allowing its particles to disperse more easily. The adhesive determines the printing characteristics of the ink as well as how it adheres to the substrate. These materials also provide appropriate gloss and wear resistance. As binders, several types of resins are often employed.

 Additives – How Screen Printing Ink with Additives Improves Print Quality and Performance, it is unavoidable for printing employees to actively adapt to changing printing conditions, utilize good inks, and enhance printing quality. It is unavoidable to add several types of ink additives with distinct characteristics to the ink. Certain ink characteristics can be improved by using ink additives.

Types of Screen Printing Ink with Additives and Their Applications 

– Solvent-based screen printing inks paints/coatings/color: 

These screen printing inks are often not ready to use and require the addition of specific thinners, hardeners, or retarders. Solvent inks work well with a variety of surfaces and can meet higher opacity and performance requirements. 

– Water-Based screen printing inks/ paints/ coatings/colors 

To communicate the color pigment, water is used as a solvent basis in water-based ink. The water-based ink is then printed on a product during the screen-printing process. The product is subsequently put through a conveyor dryer, where the water evaporates, but the pigment remains. Spinks has a wide range of water-based screen printing inks.

– UV inks or UV curing inks/paints/coatings/colour: 

Except for appropriate mixing before use, these inks are essentially ready to use. Some additives must be added in particular cases to get better outcomes on various substrates. It has a reduced footprint, faster throughput, and simple process management. UV inks appear to be the winner in display and graphics applications.

– UV LED curing Screen printing inks/paints/color: 

LED curing inks are only appropriate for commercial use. This curing process differs from mercury light curing. One of the most used techniques currently, in which there is minimal heat, and hence no cooling is necessary, which might be helpful for particular substrates like polycarbonate. It is now mainly utilized in the Narrow Web business for curing UV inks. It has significant advantages over mercury light restoration. In contrast to traditional UV screen inks, UV LED inks can travel on high-speed screen printing equipment.

– Acrylic screen printing inks/paints/colors

Acrylic inks are a relatively new type of screen printing ink. They are gaining popularity alongside their water-based cousins. Acrylic inks provide a wide range of printing processes and unique effects. In addition, acrylic screen printing inks have the potential to dry naturally. This can be useful for printing on polyester fabric, which is notorious for having curing difficulties (dye migration, discoloration, and other concerns). Screen printers have long wanted high-quality air-drying inks.

On which substrate Screen-printing inks is applied?

By utilizing the stencil, screen printing may be used to imprint on a wide variety of flat and shaped surfaces of varied forms and sizes. Fabric and paper are the two most frequent substrates used on industrial grounds, although in the event of specialist inks, other base materials may be utilized. Such as 

Screen printing inks drying techniques :

The inks are usually classified into categories based on their capacity to concentrate. In their most basic form, printing inks are liquids or extremely close to liquids. The process of changing from a liquid to a solid form is known as drying of the ink, and it can be accomplished physically, chemically, or a mix of both techniques. There are several forms of drying:

• Absorption drying- The ink dries when it travels through the surface fibers and is absorbed by the surface itself.
• Oxidation drying – The ink dries as a result of the oxygen absorption process from the environment. The gas reacts rapidly with resins, changing their mechanical state from liquid to solid.
• Evaporative drying – The evaporation rate of chosen solvents, as well as the affinity between the resins and the solvents employed, determine this form of drying.
• Chemical drying – In this type of drying is done using chemicals. These chemicals are used to keep the type of ink we are using and the surrounding condition. As chemicals react under predefined environments.
• Radiation-induced drying –  under this drying is done using different types of radiation such as ultraviolet radiation (UV ),  infrared.
