After the English cards went to print, we did the whole set again in French.
This sounds like a copy-paste job and it is not. French runs roughly 15–20% longer than English for the same meaning. So The First Lap Starts Here becomes something noticeably longer, and every headline you carefully sized to fill one line now wraps to two — which pushes the subhead down, which pushes the price block into the QR code, which breaks the card.
You do not fix that by shrinking type until it fits. That is the tell of a translated layout, and people can read it instantly even if they can't name what's wrong. You rebuild the layout to hold the longer text at the same weight it carried in English, so the French card is not visibly the lesser version of the English one.
There is terminology to get right rather than translated, too. Race craft has an accepted rendering in French motorsport — « stratégie de course ». Program names like Super Sonic Road Race School stay in English with the trademark intact, because that is the actual name of the thing, not a phrase to be converted.
The set went through three revisions before it was right, which is about normal for bilingual work.
Worth doing properly. Canada has two official languages, and a francophone family looking at a badly-set French card can tell in about one second that they were the afterthought.
