And also – it's always nearly best to never account for CREEP in the design.

The printers do this manually based on the paper weight being used to print the job. It would be very hard to get this reprinted at a later date and the printer can't their hands the same weight or type of paper, if you've adjusted for CREEP already.

Unless the printer specifically request you add creep – which would be bizarre as they would have to calculate it based on the paper – then you should never do it.

Follow the printers instructions. If you have issues or concerns raise it with them. Good communication with the printers is vital.
