Application Overview
In many industrial production lines, black or dark-colored products require clear white coding for better visibility and traceability. Common examples include rubber parts, hoses, cables, plastic components, automotive parts and industrial packaging.
OMA JET G8500W small character CIJ printer is designed for white ink coding applications. It can print clear white text, date, batch number and product code on black or dark surfaces, helping manufacturers improve product identification and production tracking.

Application Materials
G8500W is suitable for printing on different dark-colored materials, such as:
Black rubber parts
Fuel hoses and rubber tubes
Black plastic parts
Cables and wires
Automotive components
Industrial molded parts

Printing Content
The machine can print variable information including:
Production date
Batch number
Lot code
Product model
Serial number
Simple text
For example, on black rubber parts, G8500W can print white date and batch information clearly, making the code easy to read during production, storage and inspection.
Why Use G8500W?
G8500W uses white ink to create high-contrast coding on dark surfaces. Compared with black ink, white ink provides better visibility on black rubber, plastic and cable materials.
It is suitable for continuous production lines and can support stable online coding for industrial products.
Sample Testing Support
Different rubber and plastic materials may have different surface treatments, which can affect ink adhesion. OMA JET can provide sample testing before order confirmation. Customers can send real product samples, and we will test the printing effect and provide photos or videos for confirmation.
