ORA supply a range of squeegee edge profiles, In addition to the
common square edge there are a variety of single and double bevel
profiles that fulfil various mechanical and printing
requirements. For identification purposes each profile has been
given its own reference G1, G2 etc
G1
Square edge 90 deg blade is used for a wide range of graphic and textile
printing applications where a high ink deposit is required. Suitable for
manual and automatic printing.
G2
Single bevelled squeegees used for printing into non-absorbent surfaces
such as plastic, glass or metal. Conforms easily to irregular surfaces
while maintaining excellent ink deposit. Widely used on container
printing and also good on bottle printing.
G3
This double bevel edge blade (60 & 45 deg) provides excellent control for
direct printing onto cylindrical surfaces and irregular forms, also fine
print for textiles.
G4
This double bevel flat edge blade is used on most substrates including
direct ceramic printing. The profile allows for maximum ink shear and
good angle control when depositing ink with a wide range of viscosity
on multiple substrates.
G5
Blade will flex less preventing roll over, the angle is therefore
maintained giving excellent ink shear. The softer edge allowing
for good ink deposit.
G6
Square edge Composite Triple hardness blade gives the printer the
responsiveness of a soft to medium hard blade without the undesired
flexing created by increased secondary force squeegee pressure.
Excellent for printing on high mesh counts (120/140 threads/cm)
with high tension..
G16
The single bevel flat edge blade, allows for increase squeegee angle
while maintaining the sharp edge for maximum ink shear on cylindrical
substrates. Works well with high viscosity ink.
SOLVENT SWELLING
Although polyurethane is generally recognised as being highly resistant
to solvents, it is nevertheless recommended that where necessary, samples
of less common solvents be supplied for evaluation in our laboratory to
enable us to supply the most suitable grade. Resistance to solvent
swelling is increased as polyurethane hardness increases. All polyurethanes
will absorb solvents to some degree. However, what is most important is the
ability of the polyurethane to resist edge breakdown when subjected to solvent
ingression.
