Example: Our Book has 250 pages printed on uncoated paper 80 g/m2, spine width = 250 x 0,05mm = 12,5mm ~ 13mm
Preparing cover for A4 size (210mm x 297mm)
horizontal length: 210mm x 2 + spine + 6mm bleed = 426mm + spine;
vertical length: 297mm + 6mm bleed = 303mm
Preparing cover for A5 size (148mm x 210mm)
horizontal length: 148mm x 2 + spine + 6mm bleed = 302mm + spine;
vertical length: 210mm + 6mm bleed = 216mm
Preparing cover for B5 size (170mm x 240mm)
horizontal length: 170mm x 2 + spine + 6mm bleed = 346mm + spine;
vertical length: 240mm + 6mm bleed = 246mm
