There are 6 main types of printing processes: digital printing, flexography, letterpress printing, offset printing, rotogravure, and screen printing. Each uses different techniques such as raised plates, etched cylinders, or woven mesh to transfer ink in various applications like packaging, books, fabrics, and more. Digital printing refers to printing directly from a digital image source onto various media like photos. Flexography uses flexible plates to transfer images onto absorbent or non-absorbent materials like packaging. Letterpress is the oldest method using raised surfaces to imprint an image in reverse.
2. Types of printing?
Not one, not two, there are 6 types of printing
process:
• Digital Printing
• Flexography
• Letterpress Printing
• Offset Printing
• Rotogravure
• Screen Printing
3. Digital Printing
Digital printing refers to methods of printing from
a digital-based image directly to a variety of
media. It usually refers to professional printing
where small-run jobs from desktop
publishing and other digital sources are printed
using large-format and/or highvolume laser or inkjet printers.
6. Flexography
Flexible printing plates made of rubber or plastic.
The inked plates with a slightly raised image are
rotated on a cylinder which transfers the image
to the substrate. Flexography uses fast-drying
inks, is a high-speed print process, can print on
many types of absorbent and non-absorbent
materials, and can print continuous patterns
(such as for gift wrap and wallpaper).
9. Letterpress Printing
Letterpress is the oldest form of printing. In this
method, a surface with raised letters is inked
and pressed to the surface of the
printing substrate to reproduce an image in
reverse. Typically, metal type has been used
but other possibilities include carved wood or
stone blocks.
12. Offset Printing
Most common commercial printing technology in
which the image to be printed is photographically
transferred to a metal or plastic printing plate which
is wetted by water. The image portion of the plate
repels water but picks up oil-based ink from a roller,
and the non-image areas retain water but repel the
ink. The inked image is then transferred first to
a sheet of rubber or plastic which transfers it to
the paper. The objective of this double transfer it to
avoid the printing plate's contact with paper (and
thus reduce its wear) which has a rougher surface
than the blanket.
15. Rotograuve
An intaglio printing process in which letters and
pictures are transferred from an etched copper
cylinder to a web of paper, plastic, or similar
material in a rotary press.
18. Screen Printing
Screen printing is a printing technique that uses
a woven mesh to support an ink-blocking stencil to
receive a desired image. The attached stencil forms
open areas of mesh that transfer ink or other
printable materials which can be pressed through
the mesh as a sharp-edged image onto a substrate.
A fill blade or squeegee is moved across the screen
stencil, forcing or pumping ink into the mesh
openings for transfer by capillary action during the
squeegee stroke. Basically, it is the process of using
a stencil to apply ink onto a substrate, whether it be
t-shirts, posters, stickers, vinyl, wood, or other
material.
