The
main difference between soft hardcover books and hard hardcover books is that
the cover materials and their processing equipment are completely different.
Generally,
the cover weight of soft hardcover paper is about 300g / m2, which belongs to
paper jam. The processing equipment is simple in comparison with efficiency.
The printed color cover is decorated on the surface, then die-cut in size, and
then put on the shell making machine or manual shell making. The equipment used
mainly includes film covering machine, oil passing machine, polishing machine,
calender, die-cutting machine, shell making machine, bronzing machine, etc.
The
processing of plastic cover is relatively complex. The pictures and texts of
plastic sheet are printed by screen printing machine, and then high-frequency
die-cutting is carried out after oil and drying process. The equipment used
includes screen printer, screen oiler, UV dryer and high-frequency die-cutting
machine. Plastic cover materials are mostly PVC synthetic materials, and
special screen UV polishing oil is generally used for oil passing.
Soft hardcover book printing is more
exquisite and durable than paperback books, and are more exquisite in materials
and binding than paperback books. In addition to paper plastic and plastic
covers, soft hardcover books also have coating, resin impregnation, coating
impregnation, PVC frosting, recycled leather, synthetic leather, fabric
composite, paper composite and other materials. Of course, plastic cover and
film cover are the most widely used. They have the advantages of oil resistance
and dirt resistance. They are the mainstream materials for the cover of soft
hardcover books.
With
the continuous development of post press binding technology, the cover design
and materials of soft hardcover books are becoming more and more mature and
colorful. Moreover, with the vigorous rise of fast printing stores, I believe
there are many personalized makeup frame books that favor the soft hardcover book printing method, such
as personalized scheme, bidding document, recipe printing and packaging, which
is also a new field of soft hardcover book processing. The wide application of
soft hardcover technology has brought vitality to the field of book binding and
book market.
