Unlocking the Potential of Rotary Printing on UV Printers: A Step-by-Step Guide
Body:
Rotary printing devices offer a unique and versatile solution for printing on cylindrical objects such as bottles, mugs, and cans using UV printers. This guide provides detailed instructions on how to install and use a rotary printing device to achieve high-quality prints on curved surfaces.

Preparation Before Installation

  1. Power on the Machine: Switch the UV printer to machine mode.
  2. Open Software in Platform Mode: Move the platform out of the printer.
  3. Move the Carriage to the Highest Position: Ensure the printhead is elevated.
  4. Quit the Software and Switch to Rotary Mode: Prepare the printer for rotary printing.

Installation of the Rotary Printing Device

  1. Locate the Screw Holes: Identify the four screw holes around the platform, which correspond to the rotary device’s mounting points.
  2. Adjust the Stand Height: Use the four screws to adjust the height of the rotary stand. Lowering the stand allows for larger objects like bigger cups.
  3. Install Screws and Signal Cable: Secure the rotary device using the screws and connect the signal cable.
  4. Check Installation: Open the software, switch to rotary mode, and use the feed or back function to ensure the device is correctly installed.

Setting Up and Printing

  1. Adjust Y-Axis Movement Speed: Set the Y-axis movement speed to 10.
  2. Place Cylindrical Material: Secure the cylindrical object (e.g., bottle or mug) on the rotary holder.

Calibration Steps

  1. Create a Calibration Image: Design a calibration image with dimensions 100mm x 100mm.
  2. Create a Wireframe Image: Set the image height to 100mm and width to 5mm, centered.
  3. Select Mode and Send: Send the calibration image to the printer.
  4. Set Print Head Height: Adjust the print head height to 2mm above the material surface.
  5. Enter X Coordinate: Input the starting X coordinate based on the platform scale.
  6. Print Calibration Image: Print the calibration image without selecting the Y coordinate.

Adjusting Print Length

  1. Measure Actual Print Length: Use a tape measure to check the actual printed length. If the set length is 100mm but the actual length is 85mm, adjust the input value.
  2. Update Parameters: Enter the set length (100mm) and actual length (85mm) into the software. Click “Calculate” and “Apply” to save the parameters.
  3. Confirm Calibration: Reprint the calibration image to confirm the adjusted settings.

Final Printing

Once the calibration is complete and the printed length matches the set length, you can proceed with printing your final design. If minor adjustments are still needed, continue to fine-tune the settings in the software.

Conclusion

Rotary printing devices significantly expand the capabilities of UV printers, allowing for high-quality prints on cylindrical objects. By following these steps, users can achieve precise and consistent prints on a variety of materials.
