Reading scores in orchestras for å visual impaired with need for enlargement

Hi

I am just wondering if musescore is handy for reading music scores as a visual impaired with need for enlargement 200x zoom. I have a student which are playing trombone but with sight problems and need to enlarge the scores 200 times. Can Musescore do that job on for instance a iPad? Can i t follow the score so you don't have to change focus manually. ?

Thx
