Are Sublimation Plates Food Safe? [Here’s How to Check it]

Sublimation plates are popular as showpieces. They brighten up the atmosphere and make an excellent present for Christmas. But after using dozens of sublimation mugs and tumblers, you start wondering, can you serve food on sublimation plates? 

To provide you clarity on this topic, I’ve written this article describing the in and outs of sublimation plates. You’ll get to learn whether sublimation plates are food-safe, how you can make them, and how to detect a food-safe sublimation ink. 

So, stay tuned and keep reading the article till the end. 

Are Sublimation Plates Food Safe?

Yes, sublimation plates are food safe. They don’t contain any toxic or harmful ingredients. But most of the manufacturers don’t recommend using them for serving food. It’s because most of the sublimation plates don’t use food-grade sublimation ink. 

Can You Eat Off A Sublimation Plate?

Yes, you can eat off a sublimation plate if the plate has food-safe certifications like ISO-9001 and MSDS. ISO-9001 approves the quality of the sublimation plates. 

On the contrary, MSDS or Material Safety Data Sheet informs if there are any potentially hazardous chemicals in the plate and how you should use it. 

Is Sublimation Ink Food Safe?

Yes, sublimation ink is food safe. Usually, the inks are BPA-free and don’t contain any toxic ingredients. BPA means Bisphenol-A which is a harmful chemical for human body. 

Usually, it’s used in manufacturing plastics and epoxy resins. Sublimation inks from reputed brands don’t contain BPA. 

But some sublimation inks can produce fumes when heated on a neoprene substrate. As a result, a strong odor will contaminate your food on the sublimation plate. 

So, if you’re using low-grade sublimation inks, you shouldn’t use them for making a food-safe sublimation plate.  

What are the Sublimation Plates?

Sublimation plates are blank polymer-coated plates that support sublimation ink with heat and pressure. You can sublimate on different kinds of plates like metal, ceramic, and glass plates. 

Now, whatever the material is, if the plate doesn’t have a polymer coating, the sublimation ink won’t embed into the plate. You can either buy a blank plate and put a polymer coating yourself or purchase a blank sublimation plate having already coating on it. 

How Are They Made?

The sublimation plates are made with sublimation inks pressed with a heat press on the preferred part of the plate. First, you have to print out the design on Teflon paper. Then, put the paper on the plate and place it on the heat press. 

By adding the correct heat and pressure, the patterned ink will embed into the plate. Finally, let the plate cool down and you have a beautiful sublimation plate. 

You’ll get to learn more about the process in the later sections. But for now, you should know why generally sublimation plates are considered food-safe.  

Reasons Why Sublimation Plates Are Safe

There are 4 reasons why sublimation plates are food-safe. 

These are: 

  • They are made of high-grade, BPA-free material.
  • They have a special glaze at the end of sublimation for protecting against food contamination. 
  • The plates are usually non-porous to prevent bacteria buildup. 
  • The plates are sublimated with non-toxic printing materials (e.g., sublimation ink, heat press, sealants). 

Now, let’s dive into the details to learn how these characteristics actually make a sublimation plate safe.  

Reason 1: High-Grade Material

A safe sublimation plate is made from high-grade melamine or ceramic material. Melamine and ceramics contain BPA-free properties. So, they are widely used in serving foods. 

Moreover these sublimation plates can withstand high temperatures. So, even if you serve hot food on sublimation plates, it doesn’t affect the ink.  

Reason 2: Special-Glazed Plate

Another reason sublimation plates are safe is having a special glazed coating at the end of the sublimation process. This glaze seals the sublimation ink and prevents it from mixing with food. So, this coating makes your plate food-safe whether it’s put in an oven or a dishwasher.   

Reason 3: Non-Porous Surface

Sublimation plates usually come in non-porous material. So, there’s no chance of bacteria growing up on the plates. This prevents foods to get poisoned or contaminated by the sublimation ink.  

Reason 4: Harmless Printing Materials

Finally, food-safe sublimation plates are made of non-toxic, food-grade materials and sublimation ink. They don’t melt in heat and contaminate the food. 

Check List On Is Sublimation Ink Food Safe

So, you understand, sublimation inks play a huge role in the safety of a sublimation plate. 

Here’s a checklist on how you can be sure if the sublimation ink is food safe. 

  • Check for manufacturer food-grade certifications (like ISO-9001 and MSDS certified) in the label.
  • Inspect confirmation about migration testing of the inks. 
  • Ensure that the sublimation ink doesn’t have any strong odor or taste.
  • Check the manufacturer’s reliability by reading customer feedback from Amazon, eBay, and Walmart.

So, now that you’re aware of all the food-safe reliability options, check out how you can make a food-safe sublimation plate. 

How To Check If Old Sublimated Plates Are Food Safe Or Not?

To check old sublimated plates are food safe or not, you have to figure out what type of coating and glazed were used in the plates. 

You can check the labels or user manuals browsing the web. But if you fail to extract these information, you should contact with manufacturer directly. 

Now, there are a few signs which confirms your old sublimated plates aren’t food safe anymore. In most cases, you’ll notice cracks, chips, or flaking on the plates. This means the ceramic is damaged and lead is leaching through those spots. 

Note that lead is highly dangerous for human consumption. If lead comes in contact with your food, it’ll turn your food into poison. That’s why the FDA marks old and vintage ceramics unsafe for serving food. 

Apart from ceramic damaging issues, the polymer coating or glazed coating can also deteriorate in your old sublimation plates. 

You can check it by simply leaving some food on the sublimated area for several hours. If you notice the color, odor, or taste of the food changed, this means your plate isn’t food-safe anymore.

So, this is how you can check if old sublimated plates are still food safe or not. 

How to Make a Food-Safe Sublimation Plate? 

Making a food-safe sublimation plate isn’t too complicated. It’s almost similar to sublimating on a mug or tumbler. 

Materials

Now, before you start, you should collect the following tools and materials for sublimating a plate.

  • Sublimation Plates
  • Sublimation Printer
  • Sublimation Ink
  • Heat transfer paper
  • Heat press machine

So, the first step is to get a blank polymer-coated ceramic or glass plate. Note that if the plate isn’t polymer-coated, the dye won’t stain the plate. 

Then, print your preferred design on heat transfer paper using a sublimation printer. Let the sublimation ink rest for 2-3 minutes. 

After that, put the designed transfer paper under the plate in a heat press and heat it for 385°F- 400°F at 35 psi. Keep it for around 80-120 seconds depending on the manufacturer’s guideline. 

Finally, turn off the heat press and take out the plate. You’ll get a beautiful customed design imprinted. Let the sublimation plate cool down and it’s all set!
