Chapter 1: The Dawn Sprouting from Difficulties

In early 20th century New York, Allen Smith was a young engineer passionate about printing technology. He witnessed the various limitations of the printing industry at that time, especially the threat to workers' health posed by the toxic ink used in aniline printing, which deeply touched him. So he began to study day and night in his own rudimentary laboratory how to improve this technology.

The ink transfer principle of flexographic printing machine is a relatively complex but efficient process, which mainly involves the transfer of ink from the ink hopper to the printing plate, and then to the substrate.

The divergence of inks used in flexographic and gravure printing is a result of the distinct printing principles and requirements of each process. Correct ink selection and optimization are crucial for achieving high-quality prints with the desired effects. Understanding the characteristics and properties of these inks is essential for making informed decisions in the printing process.

From its inception as a promising concept to its current status as a mature and widely used technology, corona treatment has come a remarkable journey. Its ability to efficiently modify surface properties without extensive material processing has made it a cornerstone of modern manufacturing. As we move forward, the opportunities and challenges ahead present exciting possibilities for further innovation and growth.

Flexographic printing, often referred to as flexo printing, is a popular printing method due to its efficiency, cost-effectiveness, and adaptability to a wide range of substrates. Corona treatment, a crucial step in the flexographic printing process, plays a pivotal role in enhancing the overall print quality and productivity.

Expanding upon this outline, the article thoroughly dissects the core distinctions between flexographic and gravure printing, examining their individual strengths, limitations, and suitability across different contexts. It provides a comprehensive reference for businesses to make informed choices based on their unique requirements and market dynamics.

Introduction: Flexographic printing, characterized by its versatility and efficiency in the 

packaging industry, has evolved significantly from its inception to becoming an

environmentally sustainable solution. This article delves into the journey of 

flexographic printing technology, tracing its roots to its present status as a leading 

eco-friendly packaging printing technique.
