If you observe the surface
of electrolytic grained plate with an electron microscope,
there is one thing that is clearly distinctive between
plateau flat part) and
crater dented part) as table 1 of crater shape and there
is another that is not acknowledged a plateau because
it is full of a lot of honeycomb (minute hold) as honeycomb
shape.
And among craters there is a bowl type whose mouth is
open, a jar type whose inside is deep and medium type
which is between above mentioned two type, which have
their strong and weak point of printing characteristic. |
|
| DTOP Inc.
has developed plate surface organized by various types
of roughness structure, which is called multi-grain. We
can show complete printing characteristic by mixing three
sorts of wave types having their wave length, namely Primary(20μm
~ 50μm), Secondary(2.5μm ~ 20μm)
and Micro(0.01μm ~ 2.5μm) as side picture
and integrating different printing function cause by their
wave types. |

Anodizing layer is
made by precipitating aluminum in electrolytic solution
on the positive pole and flowing electric current. when
film called barrier layer or blocking layer is formed.
Anodizing layer has a great effect upon the efficiency
of p.s. plates since it stands strongly against erosion
and abrasion and has minute pores in cell which is generated
in anodized layer.
Minute pores affect greatly on preservation is very strong. |

FOR YOUR NOTE
it is necessary
for the user to take up a positive attitude to study DTOP
Inc. p.s. plates in order to know correct
data for production of high quality prints.
that is because every p.s. plates has its special trait. |
|
● By Multi-Electrolytic Graining
of aluminum surface, it gets Fine Grain smoother.
● By Special treatment of Photosensitive layer, the film
adheres closely.
to the surface and light exposure time gets shortened
and the tone reproduction gets realized.
● The excellence in ink rising at image area, better operation
and easier maintenance at Non-Image area, guarantees high
quality color printing and other high quality printing
as well.
● High quality polishing printing is possible without
rubberizing because of easy maintenance. |
