The phrase "went to press" is commonly used in the publishing industry to refer to the point when a publication is sent to the printer for printing. However, there are several synonyms that can be used to convey the same idea. These include "sent to the printers," "finalized for printing," "ready for production," "set for publication," and "printed and bound." Each of these phrases indicates that the publication has reached the stage where it is ready to be printed and distributed to its intended audience. No matter which phrase is used, the underlying meaning is the same - the publication is ready to go out into the world.
