The label as you see it, was created in adobe Premier, a program used to create vector-based artwork.
One element was not made from scratch, this being the black backing portion.
Some years ago Ken Heugel of HProps produced a series of Proton Pack and Ecto Goggle stickers (viewable
here), and I believe he was able to scan in one of the real Night Vision Goggle labels (as many of the gutted frames on eBay still feature them), or he was able to produce a very accurate facsimile.
A few months back, a member by the name of Busybuildr on GBFans uploaded a set of Ecto Goggle lense plans he'd developed, which also included a set of the stickers Ken had produced. At first I'd used these plans to make the lenses for my Ecto Goggles, but I later used the vector version of the label as both a reference, and in the instance of the background, one element to produce the new sticker.
Once I had the vector version, I set about drawing up a new diagram of the Goggles, featuring screen accurate lenses (this sketch will be uploaded later). The sketch was scanned and scaled in relation to the background element. Once I was satisfied with the size, I rendered the pencil lines as white elements, but also added slight detail (such as on the side adjust knobs) to make the style of the new rendering reference that of the older diagram.
Once that was complete, an appropriate font (arial, I believe) was selected as it was close to the original one, and I transcribed the original operating instructions and element labels, changing parts where appropriate to either reflect the nature of the prop, or where a part had been removed (such as the power switch on the base).
The label presented is not screen accurate to the one seen in the film, but that was never the intention. The intention was to create a label that would be applied to the Ecto Goggles.
