payslips and ILR

Am applying for wifes ILR next week
I am in full time employment and the payslips i receive from work. are just on normal A4 paper cut in half and they are also in black n white, these are the company payslips that are issued to everyone,

My question is would these need to be certified as can the assesing officer turn round and say these are not genuine

I would say, Better to have them attested.
