The most common type of binding is a hard­cover / book. Sometimes examination authorities demand a transparent front, for this case soft­cover and glued bond are available. Spirals are normally chosen for copies or personal use.
Basically papers pressed in steel rail are much more durable than glued ones. Every movement of glued paper is a strain which can lead to losses, whereas steel rail bindings don't back down, even under high pressure.
Front embossing grades up and increases usability, because without it is hard to decide from which side a book should be flipped open. Embossing is available for hard­covers, glued bonds and spiral bindings.
Selecting the front foil should take into account that frosted foils are transparent on contact, but also a bit less see-through at a slanting viewing angle, on the other hand they're also much less prone to traces of wear such as creases or finger prints.

The stated margins describe the width that is no longer visible after binding. They represent explicitly binding margins. Instructions concerning page margins are prescribed by examination authority if applicable and have to be added.

Paper is available with the grammage of 80g, 100g and 120g. All are FSC-certified, wood­free, chlorine-free, bright white and qualitatively at the fore­front of their segment. In addition and in consequence of their high opacity they're hardly trans­lucent already with 80g and thus very suitable for both-sided printing.
Differences basically consist of surface feel and texture: 120g paper has a considerably heavier and there­fore higher-grade feel than paper with lower grammage, with the feel of 80g paper due to the rougher texture corresponding to 100g paper. 100g and 120g paper were coated, which means their surface was flattened with fillings in order to achieve an exact print impression and more brilliant colours.
For the purpose of a homogeneous print layout and because of varying degrees of contraction of different paper in intense heat, it is advisable to work with only one type of paper per copy.

80g paper
The already in print prices included 80g paper Double A from Advance Agro represents the premium class of office paper. Because of its high volume it feels more like a 100g paper, has a low translucency (6%) and a high degree of whiteness (165 CIE) and is appropriate to b/w prints and copies.

100g paper
The 100g premium paper Color Copy produced by mondi was developed especially for use in colour laser systems. It is coated and satin-finished on both sides. This additionally flattened surface results in exacter outlines and more colour force. Coated paper is advisable to use for a view as high-class as possible, or if graphics are contained.

120g paper
Color Copy is also provided in 120er grammage. In addition to surface characteristics described at 100g paper, 120g paper scores with its maximum grip. It is turned over very easily and leaves a high-quality impression.
