27 Feb The Science of Print: How Ink and Paper Work Together
Introduction
Printing is more than just putting ink on paper—it’s a carefully balanced process where chemistry, material science, and technology come together to create high-quality prints. At Star Print, we ensure that every detail, from ink formulation to paper selection, is optimised for the best results.
In this post, we’ll break down the fascinating science behind how ink and paper interact, why choosing the right materials matters, and how this impacts the final print quality.
1. The Role of Ink in Printing
Ink is a complex liquid designed to deliver vibrant colours, sharp details, and long-lasting results. It consists of four key components:
Pigments/Dyes – Provide colour and opacity. Pigment-based inks are more fade-resistant, while dye-based inks are brighter but less durable.
Binders – Help ink adhere to paper and prevent smudging.
Solvents – Control ink flow and drying time. Water-based inks are eco-friendly, while solvent-based inks are used for durability.
Additives – Enhance properties like drying speed, UV resistance, and adhesion.
The type of ink used depends on the printing method:
- Offset Printing – Uses oil-based or UV-curable inks for sharp details.
- Digital Printing – Uses toner or liquid ink, designed for fast drying.
- Large Format Printing – Often uses solvent, eco-solvent, or latex inks for durability.
2. The Science of Paper Absorption
Not all paper is created equal! The way paper absorbs ink dramatically affects the final print quality. Here’s how:
Coated vs Uncoated Paper:
- Coated paper (glossy, matte, silk) has a smooth surface that prevents ink from being absorbed too quickly, resulting in sharper images and more vibrant colours.
- Uncoated paper absorbs ink more readily, creating a softer look ideal for books and stationery.
Paper Weight & Thickness:
Thicker paper absorbs ink differently than thinner paper. Choosing the right weight ensures the print remains crisp without excessive ink spread.
Porosity & Absorption:
Some papers have high porosity, meaning they absorb more ink, which can lead to duller colours. Others have low porosity, preserving vibrancy and sharpness.
3. How Ink & Paper Interact for the Best Print Quality
To achieve the best results, Star Print considers multiple factors, such as:
Colour Matching: The interaction between ink and paper affects colour accuracy. For example, uncoated paper may cause colours to appear duller. Our colour management systems adjust for this.
Print Finishes: The final touch can transform the print. We offer laminations, UV coatings, and varnishes to enhance durability and appearance.
Sustainability Considerations: Choosing the right ink and paper isn’t just about quality—it’s about eco-friendliness too. We use FSC-certified papers and environmentally friendly inks to reduce our impact.
4. Why This Matters for Your Print Projects
Whether you need brochures, business cards, posters, or packaging, understanding how ink and paper interact helps you make the right choices. At Star Print, we guide our clients to select the best materials for their needs—ensuring professional, high-quality results every time.
