REA JET Marking Blocks
Inkjet - large character
Very Large Distance Marking
Marking information remains clearly readable up to print heights of approx. 700 mm, suitable for large products and long reading distances.
Modular Spray Mark Blocks
Multiple spray mark heads are combined into marking blocks for flexible alphanumeric texts, batch numbers, logos, and symbols.
Suitable for Harsh Steel and Aluminum Environments
Can work with heat-resistant and glow-proof paints for hot surfaces in steel and aluminum production lines.
Product information
REA JET Marking Blocks (Spray Mark Blocks) are pneumatically controlled spray mark solutions for large, clearly readable markings from a distance on industrial products. By combining multiple spray mark heads into one block, alphanumeric texts, material designations, batch numbers, logos, and simple symbols can be applied with print heights of approximately 40 to 700 mm, depending on type and configuration. This makes the technology particularly suitable for heavy industries such as steel and aluminum production, where markings on hot, often dirty or dark surfaces must remain clearly visible.
The systems support different nozzle diameters for variable dot sizes and can apply two-dimensional contrast layers (“color mirror”) on dark substrates. Marking blocks are typically integrated into existing REA JET ST spray mark systems and controlled via the REA JET TITAN Platform, allowing them to work in line with other coding and marking techniques.

Frequently Asked Questions
Below you will find the most frequently asked questions about GSI Colorize and how it improves your printing and packaging processes.
What are REA JET Marking Blocks mainly used for?
REA JET Marking Blocks are used where markings on products must be clearly readable from a large distance, for example for material designations, batch numbers, and logos on large steel and aluminum products.
What print heights are possible with these marking blocks?
Depending on type and configuration, marking blocks can spray alphanumeric information with print heights from approximately 40 mm to about 700 mm.
What paints and media can the systems work with?
The systems can process paints and lacquers, including heat-resistant and glow-proof paints suitable for hot surfaces in aluminum and steel production lines.
How are the REA JET Marking Blocks controlled in the line?
The marking blocks are typically integrated into REA JET ST spraymark systems and controlled via the REA JET TITAN Platform, so they synchronize with transport speed and other marking processes.
