You are to compose it in ink. 

It is to be composed in ink.

It is to be composed in ink.

Explanation:

• It is to be composed in ink.: This passive construction correctly maintains the original meaning and reverses the subject and object while using the appropriate phrasing for the passive voice.
• It is composed in ink by you.: This passive construction reverses the subject and object, but it introduces "by you" which is not present in the original sentence.
• It has to be composed in ink.: This passive construction changes the tense from present ("are to compose") to present perfect ("has to be composed"), which doesn't accurately match the original meaning.
• It should be composed in ink.: This passive construction changes the modal verb from "are to" to "should," which may alter the original intention.
