Types of Ink for Digital and Offset Printing

Selecting the correct type of printing ink is crucial for achieving optimal results in both digital and offset printing processes. Understanding the characteristics and advantages of various ink types can help you make informed decisions that align with your printing needs and desired outcomes.

From pigment inks and water-based inks to dye-based and sublimation inks and beyond, each has its own advantages and applications. Learn more below.

Offset Printing Inks

Offset printing, a traditional and widely used print method, typically utilizes several types of inks, each offering unique benefits:

• Oil-Based Inks: Commonly used in offset printing, oil-based inks are pigment particles dispersed in a drying oil, such as linseed or soybean oil. These inks provide vibrant colors, excellent coverage, and quick drying times, making them suitable for various applications.

• Vegetable-Based Inks: With a growing emphasis on sustainability and environmental responsibility, vegetable-based inks have become eco-friendly alternatives to traditional oil-based inks. Vegetable-based inks are made from renewable resources such as soybean or corn oil and offer similar performance and quality while reducing environmental impact.

Digital Printing Inks

Digital printing technologies, including inkjet and laser printing, offer versatility and efficiency, with various ink options tailored to specific printing requirements:

• Aqueous Inks: Widely used in inkjet printing, aqueous inks contain water and dyes or pigments. They produce vibrant colors, sharp details, and fast drying times, making them suitable for high-quality graphics and images on coated and uncoated papers.

• Solvent-Based Inks: Solvent-based inks are commonly used in large-format and outdoor printing applications. They contain organic solvents that evaporate during printing, leaving behind pigments or dyes on the substrate. Solvent-based inks offer excellent durability and weather resistance, making them suitable for signage, banners, and vehicle graphics.

• UV-Curable Inks: UV-curable inks are cured instantly using ultraviolet (UV) light during printing. They adhere well to various substrates, including plastics, metal, and glass, and offer exceptional durability, scratch resistance, and vibrant colors. UV-curable inks are commonly used in flatbed printers for applications such as signage, packaging, and promotional items.

Choosing the Right Ink for Your Project

• Consider the substrate: Different inks may perform differently on various substrates, so it's essential to select an ink compatible with your printing material.

• Evaluate color accuracy and vibrancy: Depending on your design requirements, choose an ink that offers the desired color gamut and saturation to achieve the desired visual impact.

• Assess environmental considerations: If sustainability is a priority, choose eco-friendly ink options such as vegetable-based or aqueous inks with low VOC emissions.
