Booklet is compact and holds plenty of information. Usually the booklet is folded up to tree times and printed on both sides.
For printing a booklet, paper with density 150-200 g / m2 is usually used, but it is also acceptable to use more dense material.
If the paper density does not exceed 150 g / m2, the booklets can get folded easily, that is, get quired. At higher material densities, a creasing is needed: the machine makes a groove in the paper, on that groove the booklet will be folded.
