Flexography
As we indicated in
previous article (Offset printing), flexography (= flexo printing) is direct
printing transferring the ink from the plate to the paper on roll other than
offset. Following are the main features of flexo printing.
Flexography
requires the product of so-called printing plates. Regarding printing plate,
with its slightly raised image and letterpress, is rotated on a cylinder and coated
by fast drying ink. Ink applied to the printing area, which is then pressed
against the paper so it transfers. Therefore flexo printing is also known as
“surface printing”, is a relief printing method that the image to be printed is
higher than the background (See below picture).
Flexography
compared with offset printing, it uses water-based inks are solvent-free, not
only quick-drying but also more environmentally friendly. However, drying of
water-based inks is extremely affected by the surrounding environment. When the
weather is humid, printing sheets are easily affected with damp. When it comes
to rain or splashing by water, the surface of printed image may easily reprint
to other objects.
The main difference
with both processes is that offset printing is only done on flat and smooth surface
while flexo printing can be used on a wider range almost any substrate with a
flexible surface. For example, it can be applied to corrugated cardboard, paper,
cellophane, plastic and fabric. By using different machines provides a clear
impression image on diverse materials. While offset printing is
well-suited for short-run work, flexography provides more economical production.
What are Advantages
of Flexo Printing:
·
Runs at high press speeds
·
Economical, with high-visibility graphics when it requires the use of
only a few colors.
·
Printed material range is more widely than other printing processes.
·
Lower investment costs for printing related equipment and maintenance.
·
Water-based printing ink is more environmentally friendly.
