Combination Mark vs Emblem Logo

thanks, this is great information,
my situation currently is that I’m working backwards.
I’m not designing from scratch but adapting what the client sends me,
in which I have little control over.

I’m struggling currently with this problem.

the sponsor logos are uploaded first as a color PNG
and then a group filter is applied over all of them afterwards…
I then need to backtrack and identify all the logos with detail loss,
restore the layers, modify them to be filter proof then re-upload them..
but there is just so much variety in complexity,
in the batches I receive…and the time spent ranges from 5min-16hours.
so I can’t give a predictable time estimate…
