Printer's Tip: 

 To take advantage of the new Postal Service standards for automation compatible letter-size booklets (effective Sept 2009), keep the size to no more than 6-1/8" x 10-1/2". The standards require that a stitched booklet have 3 tabs placed on the sides. The address must be positioned to read on the long dimension (addressed similar to a #10 envelope).  Following the revised regulations will enable you 
to take advantage of standard letter rates.
