Opacity

Opacity: The Measure of Paper’s Light Transmission

Opacity refers to how much light passes through a sheet of paper. A higher opacity level means less light can penetrate, which significantly improves readability and print quality — especially for double-sided printing. High-opacity papers prevent images or text from the reverse side from showing through, ensuring a clear and professional look. This helps maintain the visual integrity of the printed pages and provides a more pleasant reading experience.

It's different with traditional newspaper paper, which tends to allow more light to pass through. Low-opacity newspaper paper has its own unique charm and captures the authentic feel of classic newspapers. For readers, it evokes a nostalgic touch and the familiar feel of daily papers. Additionally, low-opacity newsprint is more affordable and eco-friendly, often made from recycled fibres. These qualities make it an ideal choice for high-volume printing projects where cost-efficiency and authenticity are key.

Why Is Opacity Important for Printing?

• Readability: Higher opacity prevents show-through from the reverse side, enhancing readability
• Print Quality: Ensures crisp, vibrant results without distracting transparency
• Perception: More opaque papers often feel higher in quality and more professional due to their tactile nature.

Key Factors That Influence Paper Opacity

• Paper Thickness and Quality: Thicker, high-quality papers generally offer higher opacity
• Fillers and Coatings: Additional substances in the paper reduce light transmission
• Ink Coverage: Dense ink coverage can also impact opacity levels.
