possible and release all that it picks up onto the object without any perceptible distortion.
There are 4 factors which affect this process:
1 The shape of the pad
2 The hardness of the pad
3 The condition of the surface of the pad
4 The material that the pad is made from.
The question that is always asked is what should be used to print a particular job. There is no
definitive answer, as there are thousands of different shapes of pad. They tend to come into
three basic shapes: round, rectangular, and square, and one of these is generally likely to do
the job. The shape has to be such that when the pad contacts the plate and then the object to
be printed, the surface of the pad rolls over the image. This required rolling action and the
size and shape of the image, to a large extent, will determine the pad that you use. Unless
the surface to be printed onto is very irregular, then the rule is the harder the pad is the better
the ink transfer. The ideal printing surface of the pad is very smooth but slightly matt. If pads
when new are very shiny it is necessary to dull the surface to achieve a satisfactory print. This
can be done by carefully rubbing the pad with a soft tissue soaked in solvent. Care must be
taken not to damage this surface. Maintaining surface quality is very important. The pad must
be changed if it shows signs of wear. Life of a pad is about 50,000 prints.
INK
Pad printing inks are those quick drying type because of the thin film that is required. You
should choose the ink according to material of the printing item.
PAD PRINTING MACHINE
There are different types of pad printing machines:
Manual machines
Semi-automatic machines
Fully automatic machines
In which, they can be also made to open ink tray system or closed ink cup system. The
advantage of open ink tray system is that it is normally good for large area printing. While
closed ink cup system is environmentally friendly and no bad smell. Besides those basic
printing machines, automatic pad cleaning system or automatic loading and unloading
system is also available.
