The gathered sections of the book are milled; the single pages brought about by this are glued in the cover by means of hotmelt.
+
- Cheap binding method.
–
- Poor lay-flat
- When you bend the spine of the cover, the glue will break, causing the glue to lose its functionality.
- When the hotmelt gets warmer than 60 degrees Celcius, the hotmelt will get soft again, as a result the book will fall apart.
- When the hotmelt gets colder than +8 degrees, the hotmelt, when used, will break, causing the book to fall apart.
- The hotmelt is sensitive to the solvents present in the ink, the glue might soapen. Especially in uncoated kinds of paper a lot of solvents remain in the paper.
