Thick Steel Clichés
The Cliché or Steel Plate is the carrier
of the print that will be required on the product or component.
Traditionally the plates are generally of thick steel material which is
made by a very special process of hardening and etched by chemical milling
process. As clichés or plates for pad printing have very high
importance hence selection of proper plates or clichés is extremely
critical for quality.
Varying types of clichés are used depending on the desired print
quality and quantity. The motif is recessed, etched into or washed out of
the cliché. In order to assure smooth fitting and printing, the motif
should be at a distance of at least 25 mm (1 inch) from the outer edge, and
centered on the plate. In the case of long or fine lines, the motif must be
at an angle of approx. 5° to 15° to the blade track in order for
the doctor blade not to dip too low and scoop out too much ink.
Numerous trials have shown that an etching depth of 30-35 ?m is optimal for
pad printing. Since the pad can only transfer a limited quantity of ink, a
greater depth is pointless. At an etching depth of 30-35 µm, the pad
only picks up an ink film of 12 µm. The rest remains in the depressions
of the cliché. Because the ink film consists of approx. 40 % to 60 %
thinner, which evaporates during the transfer and drying, the actual
thickness of the ink film left on the substrate comes to around 5 µm -
8 µm, in some cases, as little as 2 µm. As an exception to the
above statement, very fine fonts are etched at approx. 15 µm, and very
large motifs, at approx. 30 µm. For very large surfaces, the dip of the
doctor blade can be avoided by additionally copying a fine screen into the
Our Cliché is produced from special
tool-grade, abrasion-proof steel.
Its area of application is found primarily in the industrial sector. Steel
clichés are especially suited to high quantity printing runs and
closed ink systems. The quality of these clichés is unequaled. This
is evident from their absolute sharpness of contour, multi-stage etching,
utilization of screens of all types, very fine surface, low susceptibility
to physical damage and consistency in high quantity printing runs. The
number of prints which can be achieved using this cliché comes to at
least 1,000,000 doctoring operations.
These plates are sized, ground, toughened, lapped, polished and etched. The
whole process cycle take about 25 days. Hence standard sizes are mostly in
stock and special clichés/ plates need time.
