Digital postage Machin printed wrongly on yellow paper.

My thanks to SM who sent this picture of a 2nd class Machin (digital postage) PPI printed son yellow paper.  The denomination appears white, so it would seem that the white square within the yellow envelope wasn't as large as it should have been, leaving the margins yellow instead of white.

This is certainly against Royal Mail's requirements last time I read them.

 

Other PPIs are discussed here, and if you click on the 'PPI' label in the Labels cloud at lower right below the calendar you will find more.
