Spine thickness
To estimate spine thickness for straight spine please count inside block thickness and add 4 mm or 6 mm as for cardboards.
for uncoated paper 80 g/m2 - page count should be multiplied by 0,05mm (round up to 1mm);
for uncoated paper 90 g/m2 - page count should be multiplied by 0,055mm (round up to 1mm);
for uncoated paper 70 g/m2 - page count should be multiplied by 0,045mm (round up to 1mm);
for volume paper Ecco-Book Cream and White vol. 2.0, 70 g/m2 - page count should be multiplied by 0,0685mm (round up to 1mm);
for volume paper Ecco-Book Lux vol. 1.8, 90 g/m2 - page count should be multiplied by 0,078mm (round up to 1mm);
for volume paper Munken Print White and Cream vol. 1.5 90 g/m2 - page count should be multiplied by 0,0675mm (round up to 1mm);
for coated paper matt and gloss 115 g/m2 - page count should be multiplied by 0,045mm (round up to 1mm);
for coated paper gloss 150 g/m2 - page count should be multiplied by 0,052mm (round up to 1mm);
for coated paper matt 150 g/m2 - page count should be multiplied by 0,06mm (round up to 1mm);

Inkjet papers
To estimate spine width
for JetStar uncoated paper 80 g/m2 - page count should be multiplied by 0,05mm (round up to 1mm);
for volume paper Alto vol. 1.5 90 g/m2 - page count should be multiplied by 0,0675mm (round up to 1mm);
for volume paper Bio Top 3 vol. 1.35 90 g/m2 - page count should be multiplied by 0,06075mm (round up to 1mm);

Example: Our Book has 250 pages printed on uncoated paper 80 g/m2, spine thickness = 250 x 0,05mm + 4mm = 16,5mm ~ 17mm
To estimate spine thickness for rounded spine please count inside block thickness and multiply by a factor from tabel below and add 3 mm.
| Under 20 | 1,225 | | 20 to 25 | 1,195 | | 25 to 30 | 1,175 | | 30 to 35 | 1,145 | | 35 to 40 | 1,125 | | 40 to 45 | 1,115 | | 45 to 50 | 1,105 | | 50 to 60 | 1,095 |
Example: Our Book has 250 pages printed on uncoated paper 80 g/m2, spine thickness = 250 x 0,05mm = 12,5 * factor * 1,225 = 13,72 + 3mm = 16,72mm ~ 17 mm
Preparing cover for
A4 size (210mm x 297mm)
horizontal length: 210mm x 2 + spine + 30mm bleed = 450mm + spine;
vertical length: 297mm + 30mm bleed = 327mm
A5 size (148mm x 210mm)
horizontal length: 148mm x 2 + spine + 30mm bleed = 326mm + spine;
vertical length: 210mm + 30mm bleed = 240mm
B5 size (170mm x 240mm)
horizontal length: 170mm x 2 + spine + 30mm bleed = 370mm + spine;
vertical length: 240mm + 30mm bleed = 270mm
Inside block should be 3 mm smaller then a cover from each of four sides:
I.e.
A4 (210x297) - 204mmx291mm
A5 (148x210) - 142mmx204mm
B5 (170x240) - 164mmx234mm
There is no bleed required for black&white pages
7 mm margins is required.
Note: Do not put any text on books spine thinner then 6mm
Lines
Minimal line thickness is 0,25p (0,088mm)
Fonts
Minimal font size is 4p
All fonts in text should be converted to curves or embedded with the pdf file.
Background
Minimum colour use is 5% of any component (i.e.: C-0 M-0 Y-0 K-5)
Full blackness is achieved by using only black component (C-0 M-0 Y-0 K-100), no need to use other components
Colour - only CMYK scale in every graphic project. If you want to use spot colours (Pantone, HKS, etc.) you should look for
adequate CMYK representation.
Gradients
Gradients shouldn't be less then 5% of tonal transition.
Resolution
Pictures and graphics should have 300DPI resolution and CMYK colour space (SWOP Coated CMYK)
Files
Prefered file format is PDF. Other file formats are accpeted but we will charge additional fee for converting.
Accepted file formats:
CDR CorelDraw ver. 11, fonts converted to curves, CMYK
JPG resolution 300 DPI, maximum quality, CMYK
