General guidelines
The following guidelines will assist you when you are preparing page material. The more carefully you prepare the material before it is sent to press, the more time will be saved in the production stage. Unnecessary costs will be avoided and the end result will meet your expectations.
Page size and trimming margins
The size of the publication has to be exactly the same as the final trimmed size of the product. Bleed should extend 5 mm over the trimming line. Please, set bleed for cover and case according to the template you recive from Grafostil.
Avoid text cutting
You will avoid text cutting if you do not position text or other essential elements (e.g. logos) closer than 5 mm from the trimming line. With perfectbound products the effect of the spine has to be taken into account for headline text that crosses the double-page spread. In normal cases a 3 + 3 mm margin between letters is sufficient.
NOTE! With perfectbound products do not cross body text over the spread due to a poor readability.
With perfectbound products the effect of side glueing has to be taken into account with the inside covers and on the first and last pages of the contents. Side gluing reduces the usable page area by around 8 mm starting from the spine.
Picture over the spread
With perfect bound products a part of a picture will be hidden due to glueing in product’s back. Grafostil do not pay attention to this in its imposition process. Therefore, if you want the picture shows without ”break”, you should move picture from back to outward on both pages of the spread. Our recommendation for perfect bound products is 3 mm per page (3+3).
NOTE! With perfectbound products the side glueing between the inside covers and on the first and last pages of the contents shortens the page 8 mm from the back. This means you must move a spread picture 8+8 mm.
