Comprehensive Guide to Printing and Packaging
1. Understanding Paper Weight and Thickness
What is Paper Weight?
Paper weight is measured in grams per square meter (gsm). For example, 80gsm means that one square meter of the paper weighs 80 grams. The thickness of paper is usually measured in microns, which can be determined using a micrometer.
Choosing the Right Paper Weight for Different Products:
- Premium Gift Boxes : For gift boxes or hardcover books, the outer paper should ideally be between 110gsm to 160gsm. Coated paper should be laminated to prevent tearing and ink smudging.
- Paper Bags : Paper bags should use paper between 200gsm to 300gsm for better durability. Coated paper and white cardstock should be laminated to avoid tearing.
- Brochures and Catalogs : For image-heavy brochures, coated paper is recommended for vibrant colors. The cover should be between 200gsm to 350gsm, while inner pages can range from 80gsm to 200gsm.
- Color Boxes : Color boxes can use both coated and uncoated paper. Coated paper typically ranges from 250gsm to 400gsm, while uncoated paper ranges from 150gsm to 250gsm.
2. Structural Design of Color Box Packaging
Tubular Packaging Structure Design
Tubular packaging is one of the most common types of packaging, especially for consumer goods. The design focuses on ease of assembly and opening while ensuring product protection.
# Lid Structures:
1. Insert Flap Type : The lid has three flaps, with a main flap that extends to insert into the box. This is the most widely used lid structure.
2. Lock Type : The front and back flaps interlock, providing a secure seal, though assembly and opening can be slightly more complicated.
3. Insert Lock Type : Combines insertion and locking for a more secure closure.
4. Double Insurance Insert Type : Provides a double-lock mechanism, making it very secure and suitable for repeated use.
5. Adhesive Seal Type : Offers excellent sealing but is not reusable, ideal for powdered or granular products.
6. One-Time Anti-Counterfeit Type : Features a perforated tear line to prevent reuse, commonly used in pharmaceutical and small food packaging.
7. Press Seal Type : Utilizes the paper's flexibility for easy assembly and opening, ideal for small product packaging.
8. Continuous Flap Interlocking Type : Highly decorative but more complex to assemble, often used for gift packaging.
# Bottom Structures:
1. Self-Locking Bottom : Uses interlocking flaps for easy assembly and good weight-bearing capacity.
2. Automatic Lock Bottom : Pre-glued for easy assembly and strong weight-bearing, suitable for automated production.
3. Double Insert Flap Bottom : Simple to use but has lower weight-bearing capacity, ideal for lightweight products.
4. Partitioned Bottom : Creates internal partitions to protect and separate products, offering high compressive strength.
Tray Packaging Structure Design
托盘包装常用于纺织品、服装和食品。主要结构变化在主体部分，底部基本保持不变。
# 主要组装方法：
1. 插入组件 ：无需胶水或锁，易于使用。
2. 锁组件 ：提供更安全的结构。
3. 预胶合组装 ：简化装配过程。
# 主要结构：
1. 封面类型 ：由两个独立的、相互配合的托盘结构组成，常用于服装、鞋类。
2. 襟翼类型 ：一侧具有延伸的翻盖，类似于管状包装。
3. 连续插入式 ：类似于管状包装中的连续翻盖互锁类型。
4. 抽屉式 ：由托盘和外套组成。
5. 書籍類型 ：打开方式类似精装书，常用于高端包装。

3. 印刷知识问答
为什么FSC-COC认证很重要？
FSC-COC 认证确保木制品来自负责任管理的森林。这是一项全球公认的标准，可提高公司的声誉，帮助赢得更多订单，并降低市场准入风险。
印刷和包装的关键工序有哪些？
1. 印前 ：包括设计、排版、制版。
2. 按 ：实际的印刷过程。
3. 印后 ：包括装订、层压、切割和质量检查。
什么是大豆油墨？
大豆油墨是传统石油基油墨的环保替代品。它由大豆制成，颜色鲜艳、光泽度高、稳定性极佳。它还可生物降解，对环境更安全。
什么是特种纸？
特种纸用于名片、邀请函和豪华包装等高端印刷应用。它们通常具有独特的纹理、图案或饰面，与标准纸张不同。
什么是ISO9001认证？
ISO9001 是一项质量管理体系认证，可确保公司能够持续提供符合客户和法规要求的产品和服务。它不是产品质量认证，而是侧重于组织的流程。
印刷车间对环境的要求有哪些？
印刷车间应保持清洁、无尘的环境，温度为23±3°C，相对湿度50±10%。
什么是绿色印刷？
绿色印刷是指在整个产品生命周期中使用可持续材料、减少浪费和最大限度减少污染的环保印刷实践。

4. 先进的印刷技术
层压选项：
- 哑光和光泽层压 ：保护印刷表面的标准选项。
- 柔软触感层压 ：提供天鹅绒般的触感，并增强了抗划伤性。
- 防刮层压 ：提供卓越的防划痕和磨损保护。
使用分光光度计进行颜色匹配：
对于一般产品，∆E* 值≤2.5 是可以接受的，而对于高精度产品，∆E* 应该是≤2. 这可确保不同印刷批次的颜色一致性。
装订技术：
- 骑马钉装订 ：适合页数较少的小册子。
- 完美装订 ：常见于平装书。
- 精装 ：用于高级书籍和相册。
