> Case example: adhesive plastic envelope on parcel
An adhesive envelope attached to a cardboard box is removed using Heptane.
The sticky side of the envelope was treated with Wet Powder Black.
Immediately after brushing, the envelope was rinsed under running water.
One high quality print was secured.
The same method can be applied to the adhesive side of tape, plastic bags, and vinyl gloves.
> Discarded vinyl gloves
A vinyl glove was turned inside out and then discarded.
The glove was blown up using an air pressure pistol.
