WHAT DOES FLYER PRINTING MEAN?

I just have a question regarding how to purchase on the platform. What is the measurement of an A5 document (50 % of an A4) on the platform? I wish to get a double sided flyer. I want to verify that "Full Shade" around the again aspect usually means this? Thank you! one ReplyBukit Panjang is often a household city located in the West Area of Singap
