How to adjust the printing angle on an inkjet rewinding machine?
Sep 18, 2025
As a supplier of inkjet rewinding machines, I often receive inquiries from customers about how to adjust the printing angle on these machines. Adjusting the printing angle is crucial for achieving high - quality prints, especially when dealing with different types of materials and printing requirements. In this blog, I'll share some in - depth knowledge and practical steps on how to adjust the printing angle on an inkjet rewinding machine.
Understanding the Importance of Printing Angle
The printing angle on an inkjet rewinding machine can significantly impact the final print quality. A proper angle ensures that the ink is applied evenly on the substrate, reducing issues such as blurring, smudging, and uneven color distribution. Different materials may require different printing angles to achieve the best results. For example, when printing on smooth surfaces like glossy paper, a slightly different angle might be needed compared to printing on rough or textured materials.
Types of Inkjet Rewinding Machines
Before we delve into the adjustment process, it's essential to understand the different types of inkjet rewinding machines available. There are manual and automatic models. Manual inkjet rewinding machines require more hands - on adjustment, while automatic ones often come with advanced features that can simplify the process.
- Inkjet Print Rewinding Machine: This type of machine is designed for general inkjet printing and rewinding tasks. It offers flexibility in terms of the materials it can handle and the printing patterns it can create. You can learn more about it Inkjet Print Rewinding Machine.
- Automatic Inkjet Rewinding Machine: These machines are equipped with automated systems that can adjust various parameters, including the printing angle, with minimal human intervention. They are ideal for high - volume production environments. Check out Automatic Inkjet Rewinding Machine for more details.
- Automatic Inkjet Print Rewinder Machine: Similar to the automatic inkjet rewinding machine, but with enhanced features for print quality control. You can find more information about it Automatic Inkjet Print Rewinder Machine.
Tools Required for Adjusting the Printing Angle
To adjust the printing angle on an inkjet rewinding machine, you'll need a few basic tools:
- Allen wrenches: These are used to loosen and tighten the bolts that hold the printing head in place.
- Level: A level helps you ensure that the printing head is at the correct horizontal and vertical angles.
- Measuring tape or ruler: This is used to measure the distance and alignment of the printing head.
Step - by - Step Guide to Adjusting the Printing Angle
Step 1: Prepare the Machine
Before making any adjustments, make sure the machine is turned off and unplugged to avoid any electrical hazards. Remove any materials from the machine and clean the printing head and the surrounding area to ensure accurate adjustments.
Step 2: Locate the Printing Head
The printing head is the part of the machine that sprays the ink onto the substrate. It is usually located near the top of the machine, above the rewinding mechanism. Use the machine's manual to find the exact location if you're unsure.
Step 3: Loosen the Bolts
Use the Allen wrenches to loosen the bolts that hold the printing head in place. Be careful not to remove the bolts completely, as you'll need them to secure the printing head in the new position later.
Step 4: Use the Level
Place the level on the printing head to check its current angle. If the bubble in the level is not centered, it means the printing head is not at the correct angle. Adjust the printing head by gently moving it up, down, left, or right until the bubble is centered.
Step 5: Measure and Adjust
Use the measuring tape or ruler to measure the distance between the printing head and the substrate. This distance can also affect the printing angle and quality. Make sure the distance is consistent across the entire width of the substrate. If necessary, make small adjustments to the printing head's position to achieve the desired distance.
Step 6: Tighten the Bolts
Once you're satisfied with the new angle and distance, use the Allen wrenches to tighten the bolts that hold the printing head in place. Make sure the bolts are tightened evenly to prevent the printing head from shifting during operation.
Step 7: Test the Printing
After adjusting the printing angle, turn on the machine and run a test print. Examine the print quality carefully. Look for any signs of blurring, smudging, or uneven color distribution. If the print quality is not satisfactory, repeat the adjustment process until you achieve the desired results.
Troubleshooting Common Issues
Even after following the steps above, you may encounter some issues with the printing angle. Here are some common problems and their solutions:
Uneven Printing
If the print is uneven, it could be due to an incorrect printing angle or a dirty printing head. Check the angle again using the level and make sure the printing head is clean. You may also need to adjust the pressure of the inkjet nozzles.
Blurred Prints
Blurred prints can be caused by a misaligned printing head or a problem with the ink flow. Make sure the printing head is properly aligned and that the ink cartridges are not empty or clogged.
Color Mismatch
Color mismatch can occur if the printing angle is off or if the ink cartridges are not installed correctly. Check the angle and ensure that the ink cartridges are properly seated and have enough ink.
Tips for Optimal Printing Angle Adjustment
- Regular Maintenance: Keep the machine clean and well - maintained to ensure accurate angle adjustments.
- Calibration: Periodically calibrate the machine to maintain the correct printing angle and other parameters.
- Training: Make sure your operators are properly trained on how to adjust the printing angle and other machine settings.
Conclusion
Adjusting the printing angle on an inkjet rewinding machine is a crucial process that can significantly improve the print quality. By following the steps outlined in this blog and using the right tools, you can ensure that your machine is printing at the optimal angle. Whether you're using a manual or an automatic machine, taking the time to adjust the printing angle will result in better - looking prints and increased customer satisfaction.
