The thickness and sturdiness of paper, often measured in pounds (lbs) or grams per square meter (gsm), determines its suitability for various applications. A heavier paper, generally classified as card, offers increased durability and rigidity compared to standard printing paper. For instance, paper utilized in business cards or greeting cards requires a substance providing resilience against bending and tearing.
Selecting an appropriate paper strength is crucial for ensuring print projects meet functional and aesthetic requirements. A robust material enhances perceived value and longevity, making it ideal for items subject to handling or display. Historically, the development of heavier papers has allowed for advancements in packaging, crafting, and marketing materials, contributing significantly to visual communication.
