Variable Data Printing for Mailing, Logistics and Direct Marketing Applications
In bulk mail production, every envelope may require different printed information. This can include addresses, customer data, promotional messages, barcodes and campaign-related graphics.
For this type of application, the coding and marking system must be fast, accurate and able to manage variable data at high production speed.
Application Overview
The reference application is focused on labeling of bulk mail. The production requirement is to print 650 letters per minute, with variable information changing from label to label, including a barcode. The promotional bitmap also needs to alternate from letter to letter.
This makes the application suitable for companies working with:
- Bulk mail processing
- Envelope labeling
- Direct marketing campaigns
- Logistics and postal sorting
- Variable data printing
- Barcode printing on letters and envelopes
Production Challenge
Bulk mail production is not only about speed. Each letter can carry different data, which means the printing system must receive, process and print new information continuously.
The document highlights several key requirements: extreme product speed, new variable data for each single letter, changing advertising bitmap from letter to letter, and high storage capacity for different customer and advertising logos.
REA JET HR Solution
For this application, the proposed system is REA JET HR with 2 print heads mounted to a linear motion device. The ink used is REA JET HR Black Eagle.
REA JET HR is suitable for high-resolution printing where clear text, barcodes and variable information are required on fast-moving products such as envelopes and mailing materials.
Main Advantages


The REA JET HR solution provides important advantages for bulk mail and envelope labeling applications.
It supports maintenance-free coding and marking operation, high-speed data communication via Ethernet, and active event-driven communication. The system can also transmit events such as print start and print end from the HR system.
The document also mentions 4 GB storage capacity, which is important when handling different customer data, advertising logos and variable print layouts.
Why It Matters
For mailing and logistics companies, every printed code must be readable and printed in the correct position. A missing barcode, wrong customer data or incorrect promotional print can affect sorting, delivery and campaign quality.
With REA JET HR, manufacturers and mailing companies can support high-speed envelope labeling while maintaining clear print quality and flexible data handling.
Suitable Printed Content
The system can be used to print:
- Customer-specific data
- Mailing barcodes
- Campaign codes
- Promotional bitmap graphics
- Sorting information
- Variable text
- Tracking and identification codes
