Principal of Pad Printing |
|
The basic
principal behind the pad printing technology is that the
flexible rubber silicon pad picks up the image from the etched
surface of ink flooded cliché and than transfer it to the
component, where printing is required.
Steps of Tampon printing:-
1st step- Flooding of the metal surface of plate through
forward movement of ink container.
2nd Step-Backward movement of the ink container and blade
attached to it. During this movement, the blade withdraws ink
from the plate, leaving ink in the etched area.
3rd Step - Downward movement of pad on the plate, thus
picking up the impression of the etched image.
4th Step - Forward and downward movement of pad on the
component and thus transferring the image picked up from the
etched surface.

You required pad printing machines for:
- Fine quality of printing
- Any possible size of the
component
- Difficult surface material
- Speedy production
requirements etc.
- precise registration,
excellent consistency
- Low running cost, easy to
run & maintain

How to choose Pad Printer |
|
It is quite
difficult to make a prudent decision to select a particular
pad printer when you have variety of options available in
front of you. If you are clear with the process design and
requirement details, then of course the selection becomes
easy.
To make the right pad printer
selection, we have the following suggestions:
-
You should
understand the cost of whole process, as cheaper machines
end up with higher costs in the first year itself due to
losses not accounted for during purchase i.e. ink costs,
energy costs, plate costs, downtime costs, bad quality
costs, lower yield costs.
-
Ink cup system
should be closed so that ink and solvent loss through
evaporation can be saved and ink can be prevented from dust,
dirt particles.
Machine needs to have special cross table with X/Y/Z axis ,
so that the component can be shifted according to the
precise printing position. This saves time.
-
Machine needs
to have suitable facility for quick change-over of ink cup
and etched plate, so that multiple jobs can be done in
limited time. Also the accessories for consistent print
quality should be available with machine.
Proper ink storage system in the ink cup should be
available. If, suppose during emergency, such storage is
required.
-
An advance
machine should have membrane keyboard with the following
panel functions -- inching mode, single cycle, continuous
run, multiple print, infinitely variable speed regulation,
infinitely variable doctor contact pregessure, adjustable
doctoring pressure. When less variables are to be printed
these can be avoided.
-
You need to
have clear idea of the quality desired (fine printing is
only possible with sophisticated technology like high
quality cup ring, metals for fabrication).
-
Understand, if
the supplier or manufacturer is competent enough to provide
all solutions at his premises i.e. designing studio, plate
and pad making facility, fixture or jigs making, ink and
pantone preparation, ink testing, sampling facility,
technical feed backs, after sales service, machine
guarantee, so that you need not run in different directions
for a single product printing.
-
Machine only
that machine, which can serve your customized purpose
(flexible speedy machines suitable for multicolor and
automations requirements).
-
Select the
machine that can cover maximum printing area, which can be
sometimes 360 degree as per the requirement.
-
Manufacturers
or suppliers should have proper set up (designers,
engineers, technicians) to guide you when required, as well
as display system at their site (showroom etc).
-
Machine needs
to be environmentally suitable so that it consume minimal
ink. Evaporation of solvents should be very low.
