What Is Sandwich Printing?
In sandwich printing, we print several layers of ink on a transparent label in such a way that the inside of the back label can be seen through the bottle and its contents. This effect is achieved thanks to a transparent front label that is made of PP film and implemented in the so-called no-label-look. Or, alternatively, through a cut-out in the front label through which one can look into the bottle – as in our example on the left.
A transparent sandwich printing label (also called a “double-sided label”) creates a unique effect that tells the story of your product in a very special way. This special production method is particularly popular for manufacturers in the spirits industry. Sandwich printing labels can of course also be finished with an additional hot foil. You can embellish the front layer with a foil in the colour of your choice. But please be aware that all hot foil colour contains a silver backing. For this reason only silver hot foil colour is possible on the back of your labels.
How Does Sandwich Printing Work?
With the sandwich label shown above, that was not only created by our own talented design team but which also won the HP Inkspiration Award 2018, we want to illustrate in concrete terms how sandwich printing is implemented:
#1 On the front is a no-label-look label on transparent PP film.
#2 Sandwich printing was used for the back label: two Euroscale layers were separated by a double-printed layer of opaque white (HPI White).
Please note: Depending on the design you want, the HPI white layers may not be 100% opaque. In any case, please contact our customer service for detailed advice on the possibilities and limitations of sandwich printing.
#3 The front label gives the impression of looking through a cage. This was embossed onto the transparent material of the label using golden hot foil. The cage thus frames the image of a bird on the first layer of sandwich printing on the back label. The legal information is separated from the bird by the HPI white layer and can be read from behind.
