Transform your customer's favourite memories into stunning, high-quality prints with this square sublimation rock photo slate. Designed with a smooth, glossy white coating, it allows for vibrant, detailed image transfers, making it ideal for personalised gifts, home décor, or corporate keepsakes.

With a 20cm x 20cm size and an approximate 19cm x 19cm printable area, this slate is perfect for family portraits, artistic designs, or unique signage. The natural rock edges create a rustic and elegant look, adding depth and character to any display.

Please note: As this is a natural rock product, slight variations in size and shape may occur. The edges of the slate may look rough but this is within the normal manufacturing paramaters. The white sublimation coating on these rough edges helps to create a seamless print that allows your design to look as if it is a part of the slate itself!

We sell these photo slates individuals or save 5% when buying in a wholesale bulk carton of 20 pieces. We are very competitive on our pricing and also hold very large stocks of all of our sublimation photo slates so that you can always be confident that we will have the stock you need at the price you'll love.

Please Note: Due to the natural composition of slate, slight variations in size, shape, texture, and edge finish are completely normal and to be expected. These natural characteristics are part of what makes each photo slate unique. All sublimation photo slates, regardless of manufacturer, may differ slightly from the stated dimensions. As such, minor discrepancies will not be considered defects and are not eligible for refunds or replacements.

Troubleshooting & Tips

We have tested these photo slates and recommend pressing them upside down so that the heat goes through the back of the photo slate. Heating the paper directly can cause the paper to burn and the result will not be as required.

If you are not getting good results by heating through the slate you can also heat the slate face up i.e. heating the sublimation paper directly. However if you are doing this please ensure you halve the heating time listed below. e.g. if it says 8 minutes change this to 4 minutes.

We always recommend using our 2mm thin silicone FAB Pad so that you can sublimate on the rough edges of the slate to create a seamless image.

Larger slates are generally not suitable for clamshell presses as placing the slate too close to the hinged area can apply too much pressure and crack the slate. Swing away presses are best suited for this.

We also recommend pre-heating slates if they have been stored in a colder area as the sudden temperature change can cause cracking.

Important Note: The times and temperatures below apply only to the equipment listed in the Specifications tab. These are guideline settings based on tests we've run using various machines to reflect typical customer setups. Your results may vary depending on your equipment, so some trial and error may be needed. Please contact us if you're unsure, as we can't be responsible for issues caused by incorrect settings.

Used many but never these

I am really happy with the result, I bought a box to see how they’d do and I’m over the moon with the result, I will definitely be ordering a lot more, hopefully I could claim some discounts as this is probably the best place to get your sublimation slates from, highly recommended

Longforte slates

I always use longforte for my slates however ive noticed the last few batches ive had the boxes are getting destroyed during transit, it makes it hard to give as a gift with crushed boxes, also noticing more white coating on the edges than i like making it hard to fully sublimate, but they are still the best quality slates ive had from suppliers.
