Instrument name on parts pages

When making parts from a score, if there are multiple pages to the part, the instrument name appears nowhere on the second and following pages. I.e., I've written string quartet music, made the parts, and would like to print them for performers to play live. After the first page of the violin I part the term "Violin I" appears nowhere on the following pages. Am I missing something? Shouldn't the instrument be noted on an individual page of music? Like near a page number on the printed sheet?: "page 2 violin I".
Thanks for your help!
