How to Select the Appropriate Copperplate Paper?

I. Define the Usage Scenarios and Purposes

High - end Albums and Magazines: For these printed materials, which emphasize visual texture and color expressiveness, copperplate paper with high gloss and smoothness should be selected, such as double - sided copperplate paper. Copperplate paper processed by supercalendering can achieve a smoothness of 600 - 1000 seconds, allowing the ink to adhere evenly, accurately presenting complex patterns and delicate texts with vivid and rich colors, thus enhancing the visual impact.
Food Packaging and Cosmetic Packaging: In addition to aesthetics, waterproof, moisture - proof properties, and safety are of great importance. Copperplate paper with special coating treatment can be chosen. It can not only isolate external moisture, prevent the contents from getting damp and deteriorating, but also ensure that the material meets food contact safety standards while maintaining the beautiful appearance of the packaging.
Book Covers and Product Instruction Manuals: For items that need to be frequently read and preserved for a long time, the copperplate paper is required to have good strength and toughness. Selecting copperplate paper with high coating strength, good tear resistance, and abrasion resistance can reduce the risk of damage during use or circulation.

Gram Weight Selection: Copperplate paper has a wide range of gram weights, with common ones including 80g, 100g, 128g, 157g, 200g, etc. The higher the gram weight, the thicker the paper and the stiffer the texture. For ordinary leaflets, 80 - 100g copperplate paper is more suitable as it is lightweight and cost - effective; for the covers of high - end albums, copperplate paper with a gram weight of more than 200g can be selected to enhance the sense of thickness and quality.
Thickness and Stiffness: Thickness is related to gram weight, but the thickness and stiffness of papers with the same gram weight produced by different manufacturers may vary. For packaging printed materials that need to be folded and formed, it is necessary to ensure that the paper has sufficient stiffness to maintain a stable shape and avoid sagging and deformation.
Whiteness and Gloss: Copperplate paper with high whiteness can make the printed colors more vivid; gloss affects the reflective effect of the image. Generally, for scenarios such as advertising posters and high - end product packaging that pursue visual impact, high - gloss copperplate paper can be selected; for the inner pages of books and literary albums, low - gloss or matte copperplate paper can provide a softer and more comfortable reading experience.
Adaptability to Printing Methods: Different printing processes have different requirements for copperplate paper. For example, offset printing is suitable for most copperplate papers and can present rich colors and fine graphics and texts; for digital printing, copperplate paper with a more delicate surface coating and better compatibility should be selected to avoid problems such as color difference and smudging. Before making a choice, it is advisable to communicate with the printing factory to understand the types of papers suitable for their equipment.
Ink Absorbency: The coating on the surface of copperplate paper affects the speed and effect of ink absorption. If the ink absorption is too fast, it may lead to insufficient color saturation; if it is too slow, problems such as smudging and incomplete drying are likely to occur. High - quality copperplate paper should have moderate ink absorbency to ensure that the printed products dry quickly and the colors are bright and long - lasting.
Environmental Standards: With the increasing awareness of environmental protection, more and more enterprises pay attention to the environmental friendliness of materials. It is recommended to give priority to copperplate paper produced with water - based coatings and recyclable materials, and ensure that it meets relevant environmental certification standards (such as FSC forest certification, SGS environmental testing, etc.), which can not only meet the social responsibility requirements of enterprises but also conform to the trend of the market demand for green products.
Cost Budget: The price of copperplate paper is affected by factors such as raw materials, production processes, and brands. On the premise of meeting quality requirements, it is possible to compare the prices and supply stability of different suppliers, and also consider preferential policies for bulk purchases to balance quality and cost and achieve maximum cost - effectiveness.
