The context is important, since the term has two meanings (see the definition below, form The Typesetting and Publishing Glossary). But considering the fact you mention it's related to a logo design, I tend to believe it's "set de caractere" (set of characters used for designing a logo, like Times New Roman etc.)

"Typeface - the raised surface carrying the image of a type character cast in metal. Also used to refer to a complete set of characters forming a family in a particular design or style."
