Your getting a bit mixed up with your paper sizes, there is no such paper size as 594x 210, booklets are usually done on SRA2 size and SRB1 size.The size for A4 landscape booklets is 594x210 mm, minus the trimmed border. Does it have a name? Thanks
If you follow the RA and SRA size papers then you’ll have no problems... Does anyone have any more tips?
