I'm updating Caeciliae with a few goodies, and in the process I'm adding a variant that many have requested: Caeciliae with heavier staff lines for clearer photocopying. I'd like feedback on the image below, which shows Caeciliae with 50% bolder staff lines, compared to the standard weights. If you photocopy your chants (I still highly recommend using standard Caeciliae with digital printing rather than photocopying! But some people find themselves constrained by their office/resources...), let me know if this will be strong enough for you, here or at matthew@osjoseph.org is fine.
