How to Print on Cardboard Boxes

Knowing how to print reliably on cardboard boxes with high-quality codes every time is essential. It could mean the difference between long periods of productivity and periodic workflow stoppages. To meet regulations and ensure the traceability of your products, the labels must be well-placed for clear legibility. Depending on your industry, type of products, and other factors, you may need to outfit your cardboard boxes with the following information:
 

To maximize uptime, read on to learn how to avoid some of the common complications that can arise during the process and how to print on cardboard boxes efficiently.

Challenges of Printing on Cardboard Boxes

As with any printing task, you must consider the unique properties of the base material to make the best operations and hardware choices. As a porous, brown surface, cardboard is susceptible to the following printing challenges:

Extra-Absorbent Surface

Cardboard is more porous than other materials like plastic or glass. Due to this increased absorbency, ink tends to sink deeper into the surface than with other materials. Accordingly, printing A-grade-level codes directly onto cardboard is nearly impossible. However, if correctly tested and verified, a reliable printer can still print legible codes that meet ISO/IEC standards.

Reduced Scannability

Compared to white label printing, the contrast between brown cardboard and applied black ink tops out at a significantly lower rate: 600 dpi for the former versus 200 dpi for the latter. To overcome this contrast deficit, plant managers need to use the ideal printer to apply a clean, clearly marked lot code. This crisp labeling will accentuate the difference between the material's light background and the ink's darkness, effectively neutralizing the dpi difference.

Print Mark Inconsistency

While not unique to cardboard printing, poor ink distribution can compound with a dpi deficiency, creating major readability issues on cardboard packaging. The key to avoiding this problem is ensuring your printer applies consistent pressure on the material surface. A high-quality, well-adjusted printer will ensure evenly applied characters on an ongoing basis, helping you avoid delays and shutdowns.
 

Don’t let your $10,000 printer shut down your multi-million dollar production line.

InkJet’s Cardboard Box Printing Solutions

To tackle the challenges outlined above, InkJet, Inc. has a range of products that are perfect for cardboard printing: thermal inkjet printers, high-resolution case coders, laser systems, and print-and-apply label machines.
 

Each solution has distinct application specialties, specifications, and cost factors. This table lists our various hardware options and notes their specifications. Additional information on each machine can be located further below on the page. Click the title in the table’s leftmost column to jump to a specific solution.

Thermal Inkjet Printers: Anser X1 and A1 Models

Thermal inkjet (TIJ) printers are compact, cost-effective machines with impressive coding specifications. TIJs like the Anser X1 and A1 can create 600 x 600 DPI codes up to 2” tall with stitched printheads. These qualities enable TIJ operators to complete product-marking tasks and case-coding applications.
 

TIJ printers also offer:
 

• Simple Installation. TIJ printers are compact and lightweight, enabling easy and quick line integration.
• Zero-Maintenance Operation. Thermal inkjet printers do not require printhead cleanings, ink system maintenance, or professional servicing. Users can maintain proper TIJ operation for years by performing simple cleaning tasks and following basic usage guidelines. 
   

TIJ printers are often designed for slower speed lines and intermittent coding tasks, but some TIJ models offer high-speed capabilities. InkJet, Inc. carries TIJ printers of varying specialties and price points.

See the chart below for a closer look into how our TIJ options compare to one another:
 

 High-Resolution Case Coders: Precision Series 18mm & 72mm

High-resolution case coders (hi-res) excel at placing high-quality images and codes on cardboard boxes. InkJet, Inc.’s Precision Series 18mm and Precision Series 72mm are ideal for secondary and tertiary packaging tasks. 

 High-resolution case coders use powerful piezoelectric printheads to create large messages, intricate graphics, and stark images. Hi-res ink is oil-based and thicker than TIJ ink, making hi-res codes more durable and visually appealing. For some cardboard boxes, hi-res ink is better suited to achieve barcode scan ability and contrast at the most economical ink price. As case-coding solutions, Precision Series systems enable users to replace physical shipping labels with printed codes, text, and images by directly printing on the box. 
 

 

Direct printing offers numerous benefits over manual labeling, including:
 

• Faster coding times
• Fewer material costs
• Lower risk of coding errors
• Better code durability
• Improved print quality
   

In addition to these factors, Precision Series case coders provide users with these unique features:
 

• Internal Barcode Generation. Precision Series case coders can operate as completely standalone machines. Equipped with label design software and internal memory, Precision Series case coders allow users to create and store designs without an external computer.
• Seamless System Integration. Precision Series case coders are compatible with NiceLabel and Windows systems, enabling easy integration with external networks.
• Dual-Head Functionality. Precision Series printers can be equipped with two printheads, allowing operators to print on two box sides simultaneously, whether for repeat images or independent codes. Users can stack heads to increase image size as well.

Laser Marking Solutions: Fiber, CO2, and UV Laser Models

Laser marking systems are perfect for companies that require high-coding speeds, reliable accuracy, and exceptional code appearance. High-output operations frequently use laser systems to meet demanding quotas, minimize coding errors, and enhance their products’ visual appeal. As laser marking machines have become more affordable, they have become increasingly popular with smaller-scale companies.

 

 

Laser systems are more expensive than printers but do not use any consumables. Moreover, they have minimal maintenance needs and do not require annual servicing. Depending on your output needs, these factors can make laser marking more cost-effective than printing.
 

InkJet, Inc.’s F8100C CO2 Laser Marking Machine is compatible with cardboard materials and offers the following benefits:
 

• Marking speeds up to 2000 characters/sec.
• 24/7 uninterrupted coding
• Reliable ingress protections
• Long laser tube life
• Enhanced high-resolution mark quality
• Plug-and-play laser module for easy line replacement
• User-friendly control panel via computer or smartphone app

Print-and-Apply Label Machine: Evolabel Systems
 

Print-and-apply labeling machines (PALM) streamline the labeling process by continuously creating and applying labels to passing products or shipping cartons. Predominantly 

used to label shipping cartons, PALM systems can complete primary, secondary, and tertiary applications with the right equipment. 

Users can customize their print-and-apply labelers to complete specific tasks. PALM systems consist of multiple components, with two of the most important being:
 

1. The printer module prints labels on-demand.
2. The label applicator dispenses and applies each label to a product, carton, or pallet.
    

By selecting the ideal printer/applicator combo, you can use a PALM system to label your cardboard boxes quickly, accurately, and efficiently.

By investing in an Evolabel system, you can simplify your case package labeling process, reduce risk of error, and maximize packaging efficiency.
