Why board book will warping in childrens book
printing? Material, environment and packaging
methods are the factors that cause the
deformation of children's board books. In terms
of appearance, the warping deformation of
children's board books can be divided into two
types straight warping and bending
deformation. 1.Straight Warping Straight up and
warping deformation is manifested as the cover
and inner pages are opened at a certain angle,
but they can all be kept straight. After
Childrens book printing, the Board books are
usually treated with UV coating, and then
indented. If the size and shape of the
indentation line are not suitable, the
indentation direction is not parallel to the
cardboard texture, or the cover ridge is too
small. It may cause the cardboard book to appear
straight and upturned after the book is finished,
even if it does not happen after the book is
finished, it will appear straight up and upturned
after flipping and cannot be restored. 2.Bending
Deformation Bending deformation is manifested by
bending deformation of the cover or inner page,
which cannot be kept straight. This phenomenon
usually occurs after delivery to the customer.
The main reason is that the moisture content of
the cardboard book is too high or too low. When
the external humidity is too large, the cardboard
book will expand due to moisture absorption or
shrink due to moisture loss. As a result, the
cardboard book is bent and deformed.

How to solve it when children book printing in
China? 1.For Straight Warping Adopting a
back-indentation line and increasing the
thickness of the spine by 0.5mm larger than the
thickness of the book block can better control
the cardboard book from being straight and
warped. In addition, the choice of indentation
line is also very important. Usually when using
single-end thread, the size of the indentation
line should be selected according to the paper
specifications. You can choose according to the
comparison table of the book printing company in
China, For example, if cardboard with a basis
weight of 350g/m2 , use 0.5mm1.5mm indentation
line. 2.For Bending Deformation After printed
children's books, the book has high water
content.. Therefore, it is very important to
control the moisture content of the cardboard in
children's book printing to avoid warping and
deformation of the finished book. After the book
is printed and before packaging, the children's
book should be placed in a constant temperature
and humidity environment to keep the water
content of the cardboard book stable. At the same
time, if children's board books need to be
displayed, customers should be advised to place
them horizontally. If they are placed vertically,
even if the water content is normal, they may be
bent and deformed.
