Printing plates with different screencounts using the same anilox

Can we print higher plate screencounts using the same anilox roll?
What risks might there be?
Take a look at this video pill...

Hello friend.
Thank you so much from your training video. Would you please introduce me one book in this issue

Can you please suggest how to find the LPI of the printed matter? To reproduce a job, we need to know what LPI plates are used in the original printed material so that the plates can be prepared accordingly to match the output close to the original one?
