Sublimation Slate Rectangle 11.5" x 5.5" – Personalized Photo Plaque (SBBH16)

Q:  What are the correct Time and Temperature for Sublimation Slate?

A:  Quick Settings: 400°F (204°C) for 480–600 seconds with medium-firm pressure.

Achieving vibrant, high-definition results on sublimation slate blanks requires more heat and time than standard ceramics because the stone absorbs significant energy.

• Temperature: Set your heat press to 400°F (204°C).
• Time: Press for 8 to 10 minutes depending on the slate's thickness and surface area.
• Technique: Always press face down (slate on top of the paper) using a green conductive heat pad or silicone mat to ensure the heat penetrates the uneven stone surface evenly.
• Cooling: Either allow the slate to cool in air gradually to prevent cracking OR cool in warm/lukewarm water; do not dunk in cold water.

Q:   How do I stop white spots and uneven pressure on rock slate edges?

White spots and "ghosting" near the center of rock slate are common issues caused by moisture and uneven pressure. Here is how to get a perfect edge-to-edge transfer:

1. Pre-Press: Heat the blank for 60 seconds before applying the image to evaporate trapped moisture (the main cause of white spots).
2. Use a Heat Pad: Place our specialized conductive green pad over the front of the slate during pressing. This helps the heat press contour to the rock's natural imperfections.
3. Taping: Use our high-quality JM148 heat-resistant tape to secure the paper tightly. Loose paper near the rough edges causes blurring.

Q:  Are sublimation slate blanks suitable for outdoor memorials and garden use?

Sublimation photo slates are an excellent choice for outdoor memorials, garden plaques, and house signs due to their weight and natural stone construction.

• Weatherproofing: The stone itself is water resistant and wind-resistant.  Leaving the slate outside in freezing temperatures may cause it to split unless weather proofed.  Use the acrylic mentioned below or use a sealed frame.
• UV Protection: While the hard coating is durable, all sublimation ink eventually fades in direct sunlight. To extend the life of an outdoor slate, we highly recommend applying a UV-resistant clear coat (like Krylon UV-Resistant Acrylic) after pressing. This simple step protects the vibrancy of black-and-white and full-color photos against sun damage for years.

Q:  Do you have matte vs. glossy finish options for photo rock slates?

We offer both matte and glossy sublimation slate blanks to suit different artistic styles.

• Glossy Finish: The most popular choice for family photos and vibrant artwork. The high-gloss coating enhances contrast, making blacks deeper and colors pop. It gives the stone a polished, premium look.  This is the most popular option and is always available from us.
• Matte Finish: Ideal for vintage photos, rustic home décor, and text-heavy awards. The matte coating reduces glare, making it easier to read from different angles and giving the rock slate a softer, more natural stone appearance.  This is available on request as a specialty item.
