Textile Screen Printing Formula

Description

Screen printing compound, other names are  textile screen printing ink or textile screen printing paste. It is a special ink or paste use in the screen printing process. Screen printing is a beautiful  and widely used method for converting the  images or designs onto various surfaces, including textiles, paper, plastics, glass, and more. Screen printing compounds has to provide good a adhesion, vibrant colors, and durability on the intended substrates.

Here’s an overview of screen printing compounds and their key characteristics:1.

Types of Screen Printing Compounds

There are different types of screen printing compounds designed for specific applications, including:
• Textile Inks: Used for printing on fabrics and garments. These inks having the ability  to adhere well to textiles, withstand washing, and provide soft and flexible prints.
• UV Cure Inks: These inks are cured using ultraviolet (UV) light and are suitable for printing on a wide range of substrates, including plastics, glass, and metal.
• Water-Based Inks: Environmentally friendly inks that use water as a solvent. They are mostly use for printing on fabrics and paper.
• Solvent-Based Inks: These inks use organic solvents as a carrier.
• Specialty Inks: These include metallic inks, glow-in-the-dark inks, and other specialized formulations for unique effects.

Characteristics and Components

Screen printing compounds  have a certain  specific properties, such as viscosity, color opacity, adhesion, and curing properties. They generally consist of several key components:• Pigments or Dyes: Providing a color to the ink or paste.
Binders:     Tight the pigments or dyes to the substrate after printing.
Solvents or Carriers:        Dissolve the pigments and binders to create a printable consistency.
Additives:         These can include thickeners, leveling agents, anti-clogging agents, and more to enhance the performance of the ink and achieve desired effects.

Printing Process

Screen printing involves the use of a fine mesh screen that has a stencil of the design. The screen is placed over the substrate, and the ink or paste is forced through the open areas of the stencil onto the substrate using a squeegee. The substrate is then cured, often through heat or UV light exposure, to fix the ink in place.
 

Considerations:

When making  a screen printing compound, there are many factors involves such as the type of substrate, the desired print quality and the curing methods available .Different compounds work better on different materials.
