Inkjet coders are non-contact printing systems that apply liquid ink onto products or packaging surfaces in precise, programmable patterns. These machines are commonly used to mark items with variable data such as expiration dates, batch codes, lot numbers, barcodes, logos, or traceability information. Utilizing either continuous inkjet (CIJ) or drop-on-demand (DOD) technology, inkjet coders can print on a wide variety of substrates including plastic bottles, metal cans, cardboard cartons, flexible films, glass containers, and shrink sleeves.

Widely employed in industries such as food and beverage, pharmaceuticals, personal care, and logistics, inkjet coders are valued for their speed, flexibility, and ability to integrate easily into existing production lines. Many systems also include software for centralized data control, helping maintain compliance with traceability and labeling regulations.

Typical products and applications include:

• Food and beverage cartons and cans: Expiration dates and batch codes applied during high-speed filling
• Pharmaceutical blister packs and labels: Serialized codes and barcodes for traceability
• Cosmetic packaging: Lot numbers or branding applied to curved or rigid surfaces
• Logistics and shipping boxes: Barcodes and identification labels printed directly on outer packaging
• Glass bottles or jars: Date codes and logos applied at high speeds using UV- or solvent-based inks

Additional Considerations:

• Ideal for high-speed production lines requiring real-time variable data printing
• Minimal product handling due to non-contact operation
• Available in high-resolution formats for legible graphics and small text
• Requires periodic ink and solvent replenishment and routine maintenance for optimal print quality
• Supports integration with scanners, databases, and enterprise systems for automated print management
