Postcards can be printed on various types of paper and finishes to achieve different looks and durability levels. Common paper options include glossy paper, which has a shiny surface that enhances colors and images, making them vibrant and eye-catching. Matte paper offers a non-reflective, smooth finish that gives a more elegant and sophisticated appearance, perfect for a more subtle presentation. Additionally, postcards can be printed on uncoated paper, which has a natural and textured feel, suitable for a more traditional or rustic look. Finishes such as UV coating provide added protection and glossiness, while matte coatings offer a softer, understated sheen.

Designing an effective commercial postcard involves several key practices to ensure it grabs attention and delivers its message clearly. Start with a captivating headline that instantly communicates the main benefit or offer. Use high-quality images or graphics that are relevant and eye-catching. Keep the design clean and uncluttered, focusing on the essential information. Include a clear call-to-action that prompts recipients to take the desired next step. Use contrasting colors to make important elements stand out, and ensure the postcard complies with postal regulations for mailing. Finally, proofread thoroughly to avoid errors and ensure the postcard is visually appealing and impactful.
