Do GHS labels leave room for interpretation? They shouldn’t – at all.
Loads of companies out there still decide upon GHS labelling using the old method of buying pre-printed red diamond stock and then using a plain old thermal transfer printer to put the labels together. The required hazard pictograms get printed in black, and often the unused red diamonds get covered up with a black ink overprint.
Even though thats a pretty common practice its not always the best idea.
According to the ECHA Guidance on Labelling and Packaging, having empty boxes on your label can confuse people because it looks like a hazard pictogram got accidentally left off. So the guidance suggests completely blacking out any diamonds that dont get used to stop people getting the wrong idea.

But why bother with pre-printed diamonds in the first place then?
With the Microplex logiJET TC8, GHS labels get printed out just as they should be:
- Print only the hazard pictograms that are actually needed
- Don’t need any pre-printed label stock
- No blacked-out diamonds to clear up
- Super clear and professional looking labels that leave nothing to the imagination
- Loads more flexibility with changing label layouts and hazard classifications
Instead of trying to adapt your label to fit the limitations of a plain thermal printer, the logiJET TC8 just prints the whole GHS label – including red diamonds – directly onto blank label material from scratch in one quick go.
A smoother workflow.
A cleaner looking label.
And a whole lot more confidence in the GHS labelling you’re doing.
