Paper flatness is not at all critical for most enlarging ratios. The image depth of field at the easel level is several millimetres and a good 4 blade easel will hold paper much flatter than is actually needed. On the other hand depth of focus at the negative level is very small and a tiny change of focus makes a big difference in the sharpness of the projected image.

@maris,
ok so i am getting sections of the print that are out of focus while most of it is in focus.
the negative is sharp and is not the problem
any recommendations?
We need more details. Is the paper held down on the edges, or not? If it is, does it pop up in the middle?
Have you aligned the enlarger with the baseboard? You can do this by taking a scrap negative, cutting an "X" in the emulsion from corner to corner with a needle, etc., putting it in the enlarger and focusing one of the corners. You can usually do this "by eye". If all the corners are not sharp, you need to align the enlarger and the baseboard. Check you owner's manual.
hi
using a saunders 4 blade easel and a lpl 4550 enlarger
the enlarger is a one post and head enlarger on a baseboard so theres no alignment option
the easel is holding down the paper but i am getting areas of out of focus while the negative is tack sharp
using Ilford warmtone fiber 11x14 paper
@jac
ok thanks appreciate the insight
There may not be an option to adjust it, but a scratched negative is still a good test -- unless you have a focusing aid that you can use in each corner. If nothing else, open up the lens all the way and tell us if the image on the easel appears focused in ALL corners -- WITHOUT the paper.
I keep small flat magnets on each blade, but I'd check the alignment as well...
