Why Positioning Matters for Bottle Coders

Positioning is also essential for bottle cap coding, as the cap is typically a small, often round surface that can be tricky to print on. Here’s why correct positioning for bottle cap coding is critical:

1. Size of the Cap: Caps are often small, and space is limited. Accurate positioning ensures that the text or logo fits within the space on the cap, maintaining legibility and aesthetic appeal. Coding too large or off-center can lead to wasted products or illegible codes.

2. Durability of Codes: Bottles and caps are often exposed to rough handling, moisture, and chemicals. Proper positioning ensures that the code or label stays intact, even under such conditions, making sure it remains scannable throughout the product’s shelf life.

3. Avoiding Smudging: Incorrect positioning or poor ink application can result in smudged or blurred codes, especially on caps that may be subject to more friction and handling. Ensuring proper placement and high-quality ink application is crucial for durability.

Printhead Facing Downward (Top-Down Position)

• Application: This position is ideal for printing codes on the cap or lid of a bottle.

• Advantages:

  • It allows for precise positioning of the code directly on the cap, ensuring visibility and legibility.

  • The printhead can directly apply the code to the flat surface of the lid without much risk of misalignment.

Printhead Facing Horizontal (Side Position)

• Application: This is the most common print position for sidewall printing on bottles.

• Advantages:

  • It is well-suited for high-volume production as it allows for efficient sidewall printing, ensuring that the printed codes (like batch numbers or expiration dates) are clearly visible to consumers and regulatory authorities.

  • Works well for standard bottle shapes with smooth, even surfaces.

Printhead Facing Upward (Bottom Position)

• Application: Ideal for printing codes on the bottom of a bottle.

• Advantages:

  • This position allows for discreet placement of codes (e.g., manufacturing codes or QR codes), ensuring that they are not visible during normal usage but are available for batch tracking and traceability.

Why RNJET Printers are Perfect for Bottle Coding?

• High-Quality, Crisp Printing: RNJET printers provide high-resolution printing (up to 600 dpi), ensuring that even small text, logos, and barcodes are clear and legible on bottle surfaces, regardless of size. This is crucial for both the bottle body and the cap, where fine print is often required.

• Precise Positioning: RNJET printers offer adjustable printhead positions, making it easy to position codes accurately on bottles and bottle caps. This flexibility ensures the right alignment, especially when working with different bottle shapes and sizes in high-speed production lines.

• Fast Printing Speeds: RNJET printers can operate at high speeds (up to 90 meters per minute for certain models), ensuring that they can keep up with high-volume bottle production lines without compromising print quality. This is important for maintaining production efficiency while ensuring that codes are applied correctly.

• Low Maintenance and Reliability: RNJET printers are known for their reliability and low maintenance needs, which is a significant advantage for businesses looking for continuous, trouble-free operation. This means fewer interruptions to the production line, improving overall productivity.
