The 105g white testing paper, 128g double copper paper, and 157g double copper paper have significant differences in weight, material, use, and cost. The 128g double copper paper is of medium thickness and has good versatility. The 157g double copper paper is thicker and has a firmer texture. As the weight increases, the paper becomes thicker and stiffer, but the cost is also higher. The 105g white testing paper is usually common offset paper or lightweight coated paper; it has a smooth surface but lower glossiness, strong ink absorption, and average print color performance, often used for equipment debugging, test printing, paper feeding tests, and die-cutting machine calibration. The 128g and 157g double copper paper is double-sided coated copper plate paper, with a finely coated surface that is smooth and highly reflective, providing high color reproduction suitable for high-precision printing. The 128g double copper paper is commonly used for brochures, folding pages, magazine inner pages, lightweight packaging boxes, and other colored printed materials with lower thickness requirements. The 157g double copper paper is often used for high-end albums, covers, tote bags, and rigid card boxes that require higher stiffness and color performance. If further cost savings are needed, the 105g adjustment paper can be used during the debugging stage, and the production can switch to double copper paper.
