Sublimation on slate has become increasingly popular due to its ability to produce stunning, durable images on a unique, natural surface. This guide will walk you through the entire process, from preparation to troubleshooting, ensuring you achieve perfect results every time.
1. Preparation for Sublimation on Slate
Materials Needed:
- Sublimation printer with sublimation ink
- Sublimation paper
- Heat-resistant tape
- Heat press (flat heat press machine/3D vacuum machine/mini iron heat press machine)
- Protective paper or Teflon sheet
- Heat-resistant gloves
- Sublimation slate blanks
Steps:
- Design Creation: Start by creating or choosing a design suitable for sublimation. Ensure your design is mirrored before printing to transfer correctly onto the slate.
- Printing: Print your design on sublimation paper using a sublimation printer with sublimation ink.
- Slate Preparation: Clean the slate surface thoroughly to remove any dust or debris. Use a lint-free cloth for this purpose.
- Aligning the Design: Position the printed sublimation paper on the slate, ensuring it aligns correctly. Secure it with heat-resistant tape to prevent any movement during pressing.

2. Pressing Times and Temperature
Getting the time and temperature right is crucial for successful sublimation. Here’s a general guideline:
Temperature: 400°F (204°C)–Because the hot press machine is different, here is the test temperature, can be adjusted according to the actual effect
Time: 7-10 minutes
Pressure: Medium to firm

Steps:
- Heat Press Setup: Preheat your heat press to 400°F (204°C).
- Pressing: Place a protective sheet or Teflon sheet on the heat press to prevent any ink bleed. Position the slate with the sublimation paper facing up, then cover it with another protective sheet.
- Applying Heat: Close the heat press and apply firm pressure. Start the timer and let the press do its work for 7-10 minutes.
- Cooling: Once the time is up, carefully open the press and use heat-resistant gloves to remove the slate. Let it cool before handling further.
Begin by selecting and printing your favorite images onto sublimation paper using a sublimation printer. Ensure that you reverse the images before printing to account for the mirror effect during the sublimation process. While the printed images may appear dull initially, they will become vivid and vibrant after heating. Adjust the size of the images to fit your ornaments.

3: Techniques for Successful Sublimation on Slate
- Even Pressure: Ensure the pressure is evenly distributed across the slate to avoid any uneven prints.
- Correct Positioning: Double-check the alignment of your design before pressing to ensure it’s correctly positioned on the slate.
- Protective Covering: Always use protective sheets to avoid any ink transfer onto your heat press and to protect the slate surface.
4. Troubleshooting Common Issues
Issue 1: Faded or Dull Prints
Solution: Increase the pressing time or check the temperature settings. Ensure you are using the correct sublimation paper and ink.
Issue 2: Ghosting or Blurry Images
Solution: Secure the sublimation paper firmly with heat-resistant tape to prevent any movement. Ensure the slate is immobile during pressing.
Issue 3: Uneven Color
Solution: Ensure even pressure is applied across the slate. Check for any debris on the slate before pressing.
Issue 4: Residue or Marks on Slate
Solution: Clean the slate thoroughly before sublimation. If residue remains, use a mild solvent to clean the slate post-sublimation.
Issue 5: Ink Bleeding
Solution: Use high-quality sublimation paper and ensure the protective sheet is in place during pressing.
5. Advanced Tips for Perfect Results
- Pre-pressing: Pre-press the slate for a few seconds to remove any moisture, which can affect the sublimation process.
- Testing: Conduct a test run on a small piece of slate to fine-tune the time and temperature settings for your specific heat press.
- Consistent Conditions: Maintain consistent environmental conditions, as temperature and humidity can affect sublimation results.
- Select a good slate: Select a blank slate with good coating quality and sufficient baking time, which can ensure solid color and will not stick to the printing paper.
Conclusion:
Sublimating on slate can create beautiful, lasting images with a unique touch. By following this comprehensive guide on preparation, pressing times, techniques, and troubleshooting, you can achieve professional-quality results.
