Rigid Plastic Industrial Inkjet Printing and Coding Applications ij

Rigid plastic must be marked with various codes to comply with federal and state regulations and aid in distribution. Required codes frequently include:

  • Serial numbers
  • Traceable lot codes/batch numbers
  • Production date codes
  • Packaging facility information
  • QR codes/barcodes
  • Anti-counterfeiting codes
  • Regulatory symbols
  • Sell-by/best-before dates


For a plastic that puts up with so much use and abuse, you need a printing and coding solution that’s equally resilient. That's where InkJet, Inc. technologies come in with the perfect solution for rigid plastic printing. Our printers are as reliable as they are robust, and our nontransferable inks won't melt or smudge, even under the harshest printing and use conditions.

Marking Solutions for Rigid Plastic Printing

Rigid plastic comes in many shapes, sizes, and substrates. Your specific printing needs may differ for a lightweight PET plastic versus a heavy-duty HDPE plastic—and the surface area you plan to cover also makes a difference.

Thermal Inkjet Printers: Anser U2, X1, and A1 Models


Thermal inkjet (TIJ) printers are smaller, lighter, and more cost-effective than CIJ systems. While CIJ systems typically weigh around 100 lbs and can cost around $10,000, most TIJ models weigh 5-10 lbs and cost as low as $1,499.00.          

Although thermal inkjet systems are compact and lightweight, they offer impressive coding specifications. For example, the Anser U2 Smart can create 400 x 300 DPI codes up to 0.5” tall (1” tall with the Anser U2 SmartOne). Higher-end TIJs like the Anser X1 can create 600 x 600 DPI codes up to 2” tall with stitched printheads.          

TIJ printers are often designed for slower speed lines and intermittent coding tasks, but some TIJ models also offer high-speed capabilities. InkJet, Inc. carries numerous rigid-plastic-compatible TIJ printers with varying specialties and price points. Our current options include:

The Anser U2 Smart and SmartOne Thermal Inkjet Printer: Compact and cost-effective, the Anser U2 Pro-S is an excellent choice for rigid plastic printing in applications that do not require CIJ-level marking speeds. The Anser U2 Pro-S offers a 76.2 m/min max printing speed, 400 x 300 DPI max resolution, 0.5” max print height, intuitive operation, and easy installation. 

The Anser A1 Thermal Inkjet Printer: The first all-in-one TIJ that offers 2” printing and mid-message DPI adjustments, the Anser A1 is both powerful and affordable. Built with 2 cartridge slots, the A1 can create 2” tall markings with varying DPI elements (e.g., 300 DPI QR code with 150 DPI text). The A1 maxes out at 300 m/min for product marking applications with certain cartridges. Users control the A1 through a large touchscreen interface.

The Anser X1 Thermal Inkjet Printer

The Anser X1 Thermal Inkjet Printer: Even though the Anser X1 is a thermal inkjet printer, you wouldn’t know that from its spec sheet. With printing speeds up to 300 m/min, the Anser X1 is one of the most powerful TIJs on the market today. Beyond industrial speed marking, the Anser X1 offers a 600 DPI max resolution, a 3.87” max print height (with stitched printheads), IP66 protection, and the ability to control two production lines simultaneously.

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


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

High-resolution case coders use robust piezoelectric printheads to create large messages, intricate graphics, and stark images. Hi-res ink is oil-based and thicker than CIJ or TIJ ink, making hi-res codes more durable and visually appealing. As case coding solutions, Precision Series systems enable users to replace physical shipping labels with printed codes, text, and images.         

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 further benefit users with these unique features:

Print-and-Apply Label Machine: Evolabel Systems


Evolabel on a secondary packaging line.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 are made of multiple components, with two of the most important being:       

  1. The printer module, which prints labels on-demand.
  2. The label applicator, which 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 plastic bottles efficiently. 

The Evolabel Print-and-Apply Labeler is InkJet, Inc’s PALM option. Evolabel systems are compatible with three different printer modules:

We offer numerous applicators to fulfill diverse packaging requirements. Available applicators include


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