Coding on Glass: CIJ Printers versus Laser Printers

Glass surface marking presents a unique challenge when it comes to product identification. Whether it's glass bottles, jars, or even intricate glassware, finding the right solution for coding on glass surfaces efficiently and effectively is crucial for manufacturers in the food industry. In this blog post, we'll delve into the best practices for glass surface marking and explore the benefits of two primary solutions: Continuous Inkjet (CIJ) printers and laser printers.

Understanding the Challenge

Glass surfaces pose a challenge for coding and marking due to their smooth and non-porous nature. Traditional marking methods like labels may not adhere properly or could be prone to smudging or damage. Additionally, the need for clear, high-quality printing is paramount to ensure product traceability and consumer safety.

Solution 1: Continuous Inkjet (CIJ) Printers

Continuous Inkjet (CIJ) printers are a popular choice for coding on glass surfaces due to their versatility and speed. These printers use a high-pressure pump to propel ink through a nozzle, creating small droplets that form characters on the surface. Here's why CIJ printers are beneficial for glass marking:

Versatility: CIJ printers can mark on various types of glass surfaces, including curved or irregular shapes commonly found in bottles or jars.

High-Speed Printing: CIJ printers offer rapid printing capabilities, making them suitable for high-volume production lines.

Durable Marking: CIJ printers can produce durable codes resistant to abrasion, moisture, and other environmental factors, ensuring long-lasting product identification.

Solution 2: Laser Printers

Laser printers are another effective solution for marking on glass surfaces, offering precise and permanent coding. These printers use a laser beam to etch or ablate the surface, creating high-resolution marks. Here are the benefits of using laser printers for glass marking:

High Precision: Laser printers can achieve extremely fine details, ideal for intricate designs or small characters required for product identification.

Non-Contact Printing: Laser marking is a non-contact process, minimising the risk of damage to fragile glass surfaces.

Permanent Marking: Laser markings are permanent and resistant to abrasion, making them suitable for applications requiring long-term durability.


When it comes to marking on glass surfaces in the food industry, choosing the right solution is essential for maintaining product quality, traceability, and compliance with regulatory standards. Continuous Inkjet (CIJ) printers and laser printers offer distinct advantages, providing manufacturers with versatile, efficient, and reliable options for glass surface marking. By understanding the benefits of each solution and implementing best practices, manufacturers can ensure clear, legible, and durable coding on glass products, enhancing brand visibility and consumer trust.

For coding on glass to be fully effective it requires a combination of advanced technology and industry expertise. By leveraging the benefits of CIJ printers or laser printers, manufacturers can overcome the challenges posed by glass surfaces and achieve superior results in product identification and traceability.
