LONGER How to：How to use laser to engrave ceramics

Laser engraving white porcelain can be challenging because the smooth ceramic surface reflects laser energy instead of absorbing it. In this guide, we explain how to perform laser engraving white porcelain using the RAY5 10W laser engraving machine, including surface preparation, LightBurn settings, engraving execution, and post-processing cleanup. This workflow helps improve energy absorption and achieve clear, detailed engraving results on porcelain surfaces.

What This Guide Covers

This article explains the complete process of engraving white porcelain using a laser engraver. Using the RAY5 10W laser engraving machine as an example, the workflow includes:

• Surface pre-treatment using color paper
• Engraving setup in LightBurn
• Parameter configuration (speed, power, constant output)
• Engraving execution
• Post-processing cleanup to reveal the final result

Quick Answer

To laser engrave white porcelain successfully, the surface must first be treated because porcelain reflects laser energy. A color paper masking method is used to improve absorption. Then, engraving is performed using LightBurn with specific settings, followed by soaking and cleaning to remove the masking layer and reveal the final engraved design.

Why Laser Engraving White Porcelain Matters

White porcelain is widely used in ceramics, tableware, and decorative items, but its reflective surface makes direct laser engraving ineffective. Without preparation, the laser may fail to mark the surface or produce inconsistent results.

Using a masking method improves energy absorption and allows the laser to interact more effectively with the surface. This makes laser engraving ceramics more reliable and consistent, especially for detailed patterns.

Before You Start

Requirements

• RAY5 10W laser engraving machine
• White porcelain object
• Color paper (for masking)
• Clean water container
• Soft scraping tool
• LightBurn software

Precautions

• Always work in a ventilated environment
• Do not touch laser components during operation
• Ensure the porcelain is stable during engraving
• Handle sharp tools carefully during cleaning
• Follow official machine specifications or instructions when unsure

Step-by-Step Tutorial

Below is the full workflow for engraving white porcelain using the RAY5 10W laser engraving machine.

Step 1: Material preparation

White porcelain cannot retain energy on the surface for engraving due to reflection, so it is necessary to paste color paper on the white porcelain before engraving:

i. Cut the color paper according to the size of the required engraving pattern
ii. Soak the cut color paper in water
iii. Paste the soaked color paper on the white porcelain and let it dry

Action: Prepare and apply color paper as a surface mask before engraving.
Expected result: A fully covered porcelain surface with dried color paper ready for engraving.
Important notes: Ensure no bubbles or wrinkles remain under the paper, as this may affect engraving consistency.

Step 2: Engraving parameter setting

Speed 1000mm/min; Power 100%; Open constant;

Action: Configure LightBurn settings according to the specified parameters.
Expected result: The laser is ready to engrave with stable output settings.
Important notes: These settings are critical for achieving consistent engraving results on masked porcelain surfaces.

Step 3: Engraving execution (implied workflow step)

After completing parameter setup, the engraving process is carried out using the prepared design in LightBurn on the RAY5 10W laser engraver.

Action: Start engraving the design onto the prepared porcelain surface.
Expected result: The laser engraves the pattern onto the color paper layer.
Important notes: Ensure the workpiece remains fixed during operation to prevent misalignment.

Step 4: Post-engraving processing and effect display

After engraving, put the white porcelain in water, soften the color paper again, and then use tools to scrape off the excess color paper

Action: Soak the engraved porcelain and remove the softened masking layer.
Expected result: Clean engraved pattern is revealed on the porcelain surface.
Important notes: Be gentle when scraping to avoid damaging the engraved area.

Common Problems and Solutions

Tips for Better Results

• Ensure the color paper is fully soaked before application for better adhesion
• Allow sufficient drying time before engraving begins
• Use smooth and even pressure when applying the masking layer
• Keep the engraving surface completely stable during operation
• Test on a small sample before full production
• Adjust color paper thickness depending on pattern complexity for improved precision

These small adjustments can significantly improve results when performing laser engraving white porcelain or other ceramic materials.

Frequently Asked Questions

1. Why is color paper needed for porcelain engraving?

White porcelain reflects laser energy, making direct engraving ineffective. The masking layer helps improve energy absorption.

2. Can I engrave porcelain without pre-treatment?

It is not recommended, as results will likely be inconsistent or unclear.

3. What software is used for engraving setup?

LightBurn is used for configuring engraving parameters.

4. Why is soaking required after engraving?

Soaking softens the color paper so it can be removed easily without damaging the engraved pattern.

5. What is the best laser engraver for this process?

This guide uses the RAY5 10W laser engraving machine as an example.

6. Can this method be used on other ceramics?

Yes, similar ceramic surfaces may use this method, but adjustments may be required depending on material properties.

7. What should I do if engraving results are faint?

Check masking quality, ensure correct LightBurn settings, and verify surface preparation.

Final Thoughts

Laser engraving white porcelain requires careful preparation due to the reflective nature of ceramic materials. By using a color paper masking method, correct LightBurn settings, and proper post-processing, users can achieve clean and detailed engraving results.

The RAY5 10W laser engraving machine provides stable performance for this workflow. The key to success lies in surface preparation, consistent parameter settings, and careful cleaning after engraving.
