Troubleshooting Registration Issues: White Base and Color Layer Alignment

If you've encountered registration problems when printing with a white base and color layer, you're not alone. This issue can be frustrating, but fear not, as we've gathered some valuable insights and solutions to help you get your prints back on track. In this tech overview, we'll explore common causes of misalignment and provide step-by-step instructions to resolve them.

Identifying the Problem

Symptoms: The white base consistently starts at the same spot, but the color layer's registration varies. Sometimes it prints 1/4" higher than the white, other times 1/8" higher, and it's never consistent.

Software Used: EKPrint

Potential Causes and Solutions

1. Limit Switch Position

Issue: The limit switch may not be consistently triggered at the same point during printing.

Solution: Ensure that the limit switch is not obstructed or hitting any objects during its operation. Check for items like shirts hanging over the back of the printer that might interfere with the limit switch.

2. Mechanical Stability

Issue: Mechanical components may not be securely in place, leading to registration issues.

Solution: Confirm that all mechanical parts, including belts, rails, and wheels, are firmly in position. Loose components can cause misalignment, so tighten any loose connections as needed.

3. Belt Tension

Issue: Incorrect belt tension can affect the accuracy of movement during printing.

Solution: Check the tension of the belts in your printer. Adjust them as necessary to ensure they are taut but not overly tight. Proper belt tension is crucial for precise registration.

4. Motor Current

Issue: Inadequate motor current settings can result in erratic movement.

Solution: Adjust the motor current settings on your printer's driver. Ensure that the current supplied to the motor is appropriate for its specifications. In some cases, slightly increasing the current can lead to smoother and more accurate movement.

5. Secure Placement of Garment

Issue: The garment may not be securely placed on the table, causing shifts during printing.

Solution: Ensure that the garment is placed securely and evenly on the printing table. Any irregularities in the garment's placement can lead to misalignment.

Troubleshooting Steps

Here's a step-by-step guide to resolving your registration issues:

1. Check the Limit Switch: Verify that the limit switch is not obstructed and is consistently triggered at the same point during printing.
2. Inspect Mechanical Components: Examine all mechanical parts, such as belts, rails, wheels, and the platen mount, to ensure they are secure and not loose.
3. Adjust Belt Tension: If necessary, adjust the belt tension to achieve the correct balance between tightness and flexibility.
4. Motor Current Adjustment: Review and adjust the motor current settings to match the motor's specifications.
5. Secure Garment Placement: Ensure the garment is placed securely and evenly on the printing table.

By following these troubleshooting steps and addressing the potential causes of registration issues, you can significantly improve the alignment between your white base and color layer prints. Keep in mind that a combination of factors may contribute to misalignment, so thorough inspection and adjustment are essential for optimal results.
