As pioneers of ceramic-coated doctor blades, we have
accompanied the printing industry over the half century
since our establishment. As a leading company in the
industry, we promise to continue to provide sound
reliability and the highest quality.
COMMITMENT TO MATERIALS
OUR 3 COMMITMENTS
・We endeavor only use sheet steel with minimal impurities and the highest
quality straightness and flatness.
・We always have various sizes of sheet steel on hand in order to be able to
accommodate customer requirements, making it possible to deliver promptly.
COMMITMENT TO COATING
・With our unique surface treatment technology, adhesion is extremely good for
sheet steel and as the dispersion of particles is fine and uniform, it is possible to
reduce the occurrence of burrs that can cause printing problems during use.
・As blade edges uniformly and finely wear down, durability is greatly improved.
COMMITMENT TO GRINDING
・With our independently-developed grinding technology, the blade edge, the
most important part of the doctor, is extremely smooth and is finished to a
high degree of precision.
・We offer order-made compatible blade edge sizes and formats for each
customer.
・Final sharpening inspections are painstakingly conducted for all blades.
・We can respond to diverse requests such as the processing of double-edged
blades or angled blade edges.

K Ceramic Doctors are high-grade doctor blades that we
can recommend with confidence, developed by
combining our company’s unique grinding technology
and surface treatment. Compared to our conventional
products, coating adhesion and wear and abrasion
resistance have been greatly improved. This product is
interspersed with the know-how that our company has
built up over many years.
The K Ceramic Doctor HQ®
Series was developed with the aim of
reducing printing stains such as doctor lines, scatter and dropouts
about which we receive an extremely high number of requests
from customers. As a doctor manufacturer, we have gathered
research and data over many years to develop doctor blades that
make it possible to extremely effectively reduce printing stains.
The K Ceramic Doctor HQ®
Series uses the highest quality
Swedish steel carefully selected by our company and blade
edges are processed with our unique high-precision grinding. In
addition, the surface ceramic coating has been improved and
adhesion to sheet steel and coating has been reinforced. Synergy
by improving our unique high-precision grinding and coating,
blade edges that fit quickly to the cylinder surface, good doctor
cutting and blade edges finely wear down in a uniform manner.
The lifespan of blade edges has been improved through fine
wearing down.

Ceramic Doctor Hi-Blade
The Ceramic Doctor Hi-Blade Series consists of high-grade doctor blades with improved wear
and abrasion resistance and wiping properties through surface treatment of steel doctor
blades.The product is instilled with the history and reliability that we have built up over many
years as a pioneer of long ceramic doctors.
Roots Doctor
Roots Doctor are a model that pursues slide and doctor cutting properties by adopting
components with high lubricity on surface coating. It is particularly suitable as a water-based ink
doctor. Dedicated white-type Roots Doctor are also available.
Soft Doctor
Soft Doctor are a model that maintains wear and abrasion resistance capacity while preserving a
low level of stiffness and thinly administering the thickness of the surface coating.
It is possible to reduce damage to the plate.
