If an object of certain mass in sitting on spring, does the act of it's compressing the spring absorb some of it's weight.

For example: - 

A) I place an object on a scale and the scale reads 100kg.

B) If I place it on a spring (pretend the spring as no mass) and place the assembly on the same scale under the same conditions will it now read less?

I realise the mass of the object is unchanged.  I am interested in the downward force acting on the scale.
