SUREPRINT
Doctor Blades are manufactured from highly refined strip
steel specially selected for Doctor Blades.
The final finished
product is finished with a extra-smooth edge ensuring that the blades
perform a clean wiping action on the gravure cylinder/anilox roller
immediately on start-up.
"Every
metre of Doctor Blade manufactured by Sureprint is physically inspected
to ensure that the customer receives a totally defect free product
every time thereby eliminating expensive press downtime."
SUREPRINT
Doctor blades can be used for Rotogravure and Flexographic printing
as well as for coating applications.
These doctor
blades are available in several varieties and edge configurations
based on customer application and process requirements.These are
enumerated below:
HIGH
CARBON STEEL BLADES
SUREPRINT-STANDARD:
High density carbon steel blades having a refined microstructure
suitable for Standard Rotogravure & Flexographic printing
and coating applications with solvent and water based inks.
SUREPRINT-PLUS:
High density carbon steel doctor blades having an Ultra-refined
microstrucuture which allows for low friction doctoring with minimum
wear ensuring LONG RUNNING LIFE. This blades is useful for long
run jobs and/or when working with abrasive inks to ensure efficient
printing press performance with minimum downtime.
STAINLESS
STEEL BLADES
SUREPRINT-STAINLESS:
Ultra-refined High quality doctor blades for high corrosion resistance
and long running life.Useful when printing with water based inks
with high PH value.
BLADE
EDGE CONFIGURATIONS:
SUREPRINT
Doctor Blades are available in several edge configurations:
1. LAMELLA
EGDE : also commonly called STEP Edge is the most commonly
used edge configuration preferred by customers.
Incorporating
the latest technology,SUREPRINT Doctor blades increase
productivity, improve quality and reduce wastage or rejections.
The unique shape of the lamella ensures that a constant contact
area with the cylinder is maintained throughout the life of the
blade. Resulting in uniform printing throughout the print run. Thus
no resharpening is required.
The novel shaping
process of the lamella ensures that there are no longitudinal grinding
scratches or shed marks.Also, The parallel zone of the lamella ends
in a smooth taper called dynamic zone which reduces vibrations and
fatigue.
The
Sureprint advantage - over conventional blades:
The
blade life is atleast upto 6 times longer than a conventional
blade.
The
contact area remains constant throughout the entire life
of the doctor blade.
No
change in the tonal values through blade wear.
Minimal
doctor blade pressure reduces chrome destruction and
extends cylinder life.
Less
wastage and rejections.
No
running-in time required.
No
doctor blade grinding equipment required.
Less
downtime caused through replacement of doctor blades
Constant
conditions for proofing(no tonal variations and easy colour
matching.
2.
STRONG LAMELLA: This is basically a lamella type blade
where instead of the edge being absolutely parallel to the main
blade body it is tapered between 5 to 30 microns depending on customer
requirements.This doctor blade edge helps to minimize print errors
with poor doctor blade settings and to make it a little more"forgiving".
The blade has a gradual contact edge and has increased strength
to better support the lamella.
3. Other
edge configurations are available on request.
