How to Read Paper Spec Sheets
Choosing the right paper for your business, whether it’s for printing, packaging, or POS systems, starts with understanding paper spec sheets. These sheets provide all the technical details you need to make an informed decision.
1. Understand GSM (Grams per Square Meter)
GSM measures the weight of the paper per square meter and is a key indicator of thickness and durability:
- Low GSM (60-90 gsm): Thin paper, commonly used for receipts or flyers.
- Medium GSM (90-160 gsm): Standard printing and office paper.
- High GSM (160+ gsm): Thick paper or cardstock, ideal for business cards and durable documents.
2. Brightness and Whiteness
Brightness affects print clarity and contrast. Higher brightness results in sharper, more vivid text and images:
- Standard (80-90): Suitable for everyday office printing.
- High Brightness (90+): Best for professional documents and presentations.
3. Coating Type
Paper may have a coating for smooth printing and durability:
- Uncoated: Absorbs ink well, natural texture, often used for notebooks or thermal paper.
- Coated: Glossy or matte finish, ideal for high-quality graphics, brochures, or marketing materials.
4. Thickness and Caliper
Caliper refers to the actual thickness of the paper, usually in microns or mils. Thicker paper is more durable and can withstand heavy handling, while thinner paper is lighter and cost-effective.
5. Opacity
Opacity measures how much light passes through the paper. High opacity reduces show-through, which is important for double-sided printing.
6. Paper Color and Texture
Color can affect readability and aesthetics, while texture can influence printing performance. Smooth papers are better for detailed prints, while textured papers can give a premium feel.
7. Environmental Certifications
Check for eco-friendly certifications like FSC or PEFC if sustainability is important. These indicate that the paper comes from responsibly managed forests.
8. Practical Tips for Businesses
- Match GSM and coating to the intended use: receipts, packaging, or promotional materials.
- Consider storage and environmental conditions; high humidity or heat can affect some paper types.
- Ask your supplier for sample sheets to test print quality before large purchases.
Conclusion
Reading paper spec sheets may seem technical, but understanding GSM, brightness, coating, thickness, and other details helps you select the best paper for your business needs. A clear grasp of these specs ensures better print results, longer-lasting materials, and more cost-effective purchasing.
