Fixing Misalignment and Ghosting in White and Color Layers

4.1 Step Calibration: Adjusts the feed distance to ensure accurate image scaling.

Step-by-Step Instructions:

4.1.1 Access the Calibration Menu
Open the printer control software and Click the “Adjust” section.

4.1.2 Access and Print the Calibration Chart
Click “Step Adjust”, then click “Print Adjust” to start printing the step calibration chart.

4.1.3 Find the Line That Overlaps Perfectly and Record the number.
Look at the printed chart and find the line where the two sets overlap most clearly. Write down the number shown next to that line.

4.1.4 Adjust the Calibration value
Enter the number and click “Calculate”

Step ①: Rough Adjustment (Initial Calibration)
Use the value that gives the best overlap — for example, if -3 looks best, enter -3 as the calibration number.

Step ②: Fine Adjustment (Precise Calibration)
If the result is still not ideal, make fine adjustments using decimal number, such as -2.1, -2.2… up to -2.9, until the best result is achieved.

4.1.5 Enter and Save the Calibration value
Input the final calibration number and click “Save” to apply it.

4.1.6 Check if Calibration is Complete
If the number where both left and right lines overlap is “0”, calibration is complete. If not, repeat the above steps until it is.

4.2 Vertical Alignment Calibration: Ensures white and color layers align correctly in the vertical direction.
Step-by-Step Instructions:

Step-by-Step Instructions:

4.2.1 Access the Vertical Calibration Menu
Open the printer control software and Click “Adjust”section.

4.2.2 Access the Vertical Calibration Page
Click “Head Space”→Click “Vertical”→Click “Print Adjust” to print the vertical calibration chart (Ensure the media is loaded and the printer is ready)

4.2.3 Find the Value Where Black and White Overlap
Look at the printed chart and identify the number where the black line and white background overlap most perfectly. Record that number.

4.2.4 Calculate and Set the Final Calibration Value
Use the following formula:
Final Value = Original Value + Overlap Value
Example: If the original value is 731.8 and the overlap value is -4, then:
731.8 + (-4) = 727.8
Enter 727.8 into the H2 parameter field in the system. (No need to modify the number in H1)

• Rough Adjustment: Start with the integer value where overlap is most obvious.
• Fine Adjustment: If needed, fine-tune using decimal values (e.g. -0.2, +0.3, etc.) until the overlap is perfect.

4.2.5 Save the Calibration Settings
Click “Save” to apply the new calibration value.

If the overlap value is 0, the calibration is complete. If not, repeat the steps until it is.

Step 1: Left Distance

1.1 Access the Calibration Page
Open the printer control software and go to “Adjust”section.

1.2 Print the Horizontal Calibration Chart
Click “Head Space” → then click “Horizontal” → select “Left Distance” and click the “Print Adjust” button to print the horizontal calibration chart.

1.3 Find the Overlapping Number
Check the chart and identify the number where the black and white lines overlap best. Write down this number.

1.4 Calculate the Final Number
Use the formula:
Final number = Original number + Overlap number
Example:
If the original number is -2.6, and the overlap number is -3, then:
-2.6 + (-3) = -5.6
Enter -5.6 into the H2 field. (No need to modify the number in H1)

• Rough Adjustment: Start with the integer value where overlap is most obvious.
• Fine Adjustment: If the result is still not ideal, fine-tune by using decimal values (e.g., -5.1, -5.2… -5.9) until the white and color layers align perfectly.

1.5 Save the Calibration
Click “Save” to apply the new setting.
If the overlap number is not 0, repeat the steps until it is.

When the number where black and white overlap is “0”, the calibration is completed; if it is not “0”, repeat the above steps.

Step 2: Right Distance

2.1 Access the Calibration Page
Open the printer control software and go to “Adjust”section.

2.2 Print the Horizontal Calibration Chart
Click “Head Space” → then click “Horizontal” → select “Right Distance” and click the “Print Adjust” button to print the horizontal calibration chart. (Ensure the media is loaded and the printer is ready)

2.3 Find the Overlapping Number
Locate the number where the black and white lines overlap perfectly. Record it.

2.4 Calculate and Enter the Final Number
Use the following formula to calculate the adjustment:
Final number = Original number + Overlap number
Example:
If the original number is 0.9, and the overlap number is -3, then:
0.9 + (-3) = -2.9
Enter the final number -2.9 into the H2 field.(No need to modify the number in H1)

• Rough Adjustment: Start with the closest whole number where the lines overlap best (e.g., -3, +2).
• Fine Adjustment: If the result is not ideal, fine-tune using decimal values (e.g., -2.1, -2.2…) until the white and color layers are perfectly aligned.

2.5 Save the Calibration
Click “Save” to apply the value.
If the overlap number is not 0, repeat until it is.

When the number where black and white overlap is “0”, the calibration is completed; if it is not “0”, repeat the above steps.

This issue is typically caused by uncalibrated bi-directional printing. Use the “Bidirect Adjust” function to correct it.

How to Perform “Bidirect Adjust”
Check and Adjust Bi-directional Calibration Parameters

1. Access the Adjust Page
Open the control software and Click the “Adjust” section.

2. Click “Bidirect Adjust”, then click “Print Adjust” to print the bi-directional calibration chart(Ensure the media is loaded and the printer is ready）

3. Find the Number Where Black and White Lines Overlap Best
Examine the chart and identify the number where the black and white lines align most perfectly. Write it down.

4. Calculate and Enter the Final Number
Use the formula:
Final number = Original number + Overlap number
Example: If the original number is 14.5 and the overlap number is -3, then: 14.5 + (-3) = 11.5 Enter 11.5 into Bidirect Value.

• Rough Adjustment: Start with the closest whole number where the overlap looks best.
• Fine Adjustment: If the result is still not ideal, fine-tune with decimal values (e.g., 11.1, 11.2…) until no ghosting appears

5. Save the Calibration Data
Click “Save” to apply the setting.

If the overlap number is 0, calibration is complete. If not, repeat the steps above until it is.

Part of the Printed Image is Aligned, While the Other Part Shows White/Color Misalignment

Step 1: Check if the Film is Installed at an Angle
Inspect the film on the print platform. If it’s not parallel to the platform edge, it can cause partial misalignment during printing.

Film Not Installed Parallel

Left Not Parallel

Right Not Parallel

Step 2: Release the Paper Clamps on Both Sides
Loosen the clamps on the left and right sides of the film to allow adjustment.

Step 3: Measure the Distance Between the Film Edge and Platform Edge

Using a ruler, measure the distance between the edge of the film and the edge of the platform at three points (e.g., using the outermost 3 dots on the film as reference).

If the distances are not equal, adjust the film until they are.

Step 4: Re-fix the Clamps
After confirming the film is parallel to the platform edge, re-tighten the left and right clamps to secure the film in place.

Left Clamp Aligned

Right Clamp Aligned

Step 5: Perform a Test Print
Print a test pattern to check if the image is now fully aligned without any white/color offset.

If aligned correctly, the calibration is complete.

If misalignment remains, repeat the steps above.
