I just have an issue about how to get on the System. What's the measurement of an A5 doc (half of the A4) on the System? I desire to order a double sided flyer. I need to substantiate that "Comprehensive Shade" on the back again side suggests this? Thank you! https://flyer-printing90156.like-blogs.com/36390963/the-definitive-guide-to-flyer-printing
