Metalized Paperboard

1. Three Methods to Add
the Metallic Finish

• Metalized Paperboard Printing
Three Methods to Add the Metallic Finishing:

3. • Foil stamping
• Foil stamping has 2 categories:
• hot foil stamping
• cold foil
================================
• Hot Foil
The metallic finish is created by transferring a
very thin layer of aluminum coating on the foil
paper to the intended paperboard by using
heat and pressure. The heat activates
separation coatings and adhesive coatings that
affect the permanence of the resulting finish on
the paper box.

4. • Cold Foil
• Cold foil has been growing dramatically
recently both in brand owner use and in
technical development.
• The metallic coatings from the film will
only transfer to the paper sheet where the
adhesive has been applied. The adhesive is
cured to set the metallic look with
permanence to the sheet so that additional
colors of ink can be applied directly to the
metallic surface.
• With regard to the metallic effect, the cold
foil can not rival the hot foil stamping at
present.

5. • Metallic Inks Printing
• Two types of technology are widely
used to produce metallic inks and
coatings. Of the two, the oldest
technology dates back several decades
and has traditionally been referred to
as metallic powder technology.
• The finished results of products
using metallic powder suffered from a
number of shortcomings.
• Reflectivity and brilliance was dull
at best and resistance levels to in-use
exposures were often a risk.

6. • Metalized Paperboard Printing
• The metallic effect of this method is realized by the natural
metallic color of the metalized paperboard.
• During the printing process, the CMYK inks are only
printed on the text area and the colored area. While the
transparent area on the artwork has no inks applied on the
metalized paperboard.
• Generally, there are 4 kinds of metalized paperboard used.
• The metalized paperboard can be glossy or matte.

7. Aluminum Foil Board Laminates
Foil board laminates were among the first type of processes for creating a
metallic look on paperboard. This product is produced by physically
laminating with an adhesive – a sheet of aluminum to a sheet of paper. The
manufacturing process is very efficient, however there are relatively few
companies involved in the production of aluminum foil board globally. The
finished product usually has the higher grammage value than other metallic
decorating alternatives.

8. • PET/BOPP-Metalized Paperboard
• The product is produced by
metalizing the PET or BOPP film of
choice and laminating the
metalized film to the paperboard
with an adhesive.

9. Transfer Metalized Paperboard
Transfer metalized film is
produced to create a metalized
surface on thinner caliper papers
and when weight reduction in an
application is desired. The
manufacturing process is similar to
cold foil transfer processes, but on
a larger high-volume scale.
A film is coated and metalized to
allow the layer of aluminum
metalizing to be released away.
This metalized film is placed in
contact with a paper or
paperboard that has an adhesive
applied to it. The adhesive can be
applied in a flood manner,
covering all of the sheet, or a
discrete manner, allowing
selective elements to transfer.
The paper and the film is then
stripped away releasing the
metallic aluminum, which remains
on the sheet only where the
adhesive has been applied. The
finished product is among the
lightest weight options for metallic
finishes.

10. Direct Metalized Paperboard
Direct metalized boards and
papers are typically
produced using vacuum
metallization which deposits
a very thin vapor of
aluminum directly onto the
coated paperboard. The
resulting aluminum layer
will take on the attributes of
the paper fibers or surface
profile.
Very smooth papers will
provide higher reflectivity
than less smooth papers.
Direct metalized papers and
boards are most commonly
coated with a clear coating.
The coating will provide
attributes for printing,
exposure resistance features
and final finish to the paper.
The coatings can be
cellulose-based or acrylic-
based.
Application methods will
cure using oxidation,
ultraviolet light or electron
beam. It is one of the
lightest weight options.

11. How do print offset
printing on metalized
paper?
need a UV dryer / Lamp
(because it is impossible for the
ink to dry naturally on metallized
sheet)
There are 2 options to print on
metallized sheet:
1. Buy the paper sheet and
laminate it with metallic film, now
when you buy the film, ask your
vendor to give you a ready to print
film. If you're already getting that
its no problem.
2. But if not , then you need to a
base coat (Primer Base) run on
your offset machine (offline)
for ready to print sheet:
First run: White ink opaque
Second run :White ink transparent
(if required)
Third run : 4 colour uv printing
Fourth run : Top Coating varnish
(if required)
All these processes will require a
UV dryer (UV Lamp).
* UV Cured ink can not dry with IR
* Even normal ink with an IR on a
metallized sheet (need aging
time).
