these disc shaped pieces of thin card“Analogue Tachograph Media” are printed on paper, not card (however thin you may like to describe it).
The difference between paper and card, contrary to common belief and even some marketing, is not in any way related to the actual thickness (or even mass) of the media post-production. The difference is simply defined by the production methods and component chemicals used to generate the pre-production product (or pulp) from which is processed to form what we commonly refer to as paper or card. Different processes are used to enure that card, when pressed and cut, will maintin its relative physical characteristics throughout a wide temperature and humidity range whereas paper (even when processed into thick sheetage) will behave very differently at the extremes of the environmental ranges.
Card is very expensive to produce, hence paper being much more common. Even card-board is actually made from paper stock, in order to keep it low-cost. Analogue Tachograph Media have no need to be made from card, as the wax coating provides almost all the additional benefits but the manufacturer saves the additional raw material cost of the stock, at the expense of course of the seconary waxing process which is necessary anyway in order to make the product functional.
And before anyone asks, no I’m not a sad individual who reads magazines about paper production processes (and such ‘fanzines’ do exist!), but I did work in the industry for a while.
Paper schmaper.
