I just have a matter regarding how to buy on your System. What is the measurement of an A5 doc (half of the A4) on the System? I choose to get a double sided flyer. I want to verify that "Total Shade" within the back aspect signifies this? Thank you! https://flyer-printing75295.ourcodeblog.com/31314059/the-2-minute-rule-for-flyer-printing
