Common Paper Materials and Stocks
The choice of material influences durability, texture, and how colors appear on the surface. Matching the stock to the application ensures the final piece feels premium and performs reliably in its intended environment.
Offset and Uncoated Stocks
Offset paper, often found in 70–120 gsm, provides a soft, matte surface suitable for text-heavy documents. Recycled uncoached sheets add an eco-friendly touch with a natural look, commonly used for internal communications and sustainability-focused branding.
Coated and Cover Stocks
Coated papers, available in gloss, silk, and matte finishes, enhance sharpness and color vibrancy for marketing materials. Cover weights in the 100–350 gsm range are typical for postcards, premium brochures, and high-quality invitations that demand a tactile, luxurious impression.
Size and Format Considerations for Print Production
Selecting the right dimensions affects postage, compatibility with folding techniques, and overall design clarity. Standard formats reduce setup complexity, while custom sizes may require additional finishing and handling considerations.
Postage and Handling Tips
Verify regional postal regulations for size and thickness limits, especially for mailers and direct mail pieces. DL and C5 formats fit common mail classes and automated sorting equipment, helping streamline delivery and reduce surcharges.
