1. Name: DOIE CTcP 32 Channels laser diodes white color ceramic drum
prepress printing machine like SCREEN
2. Application: Worked as plate making machine with laser diode exposing dot on
plate,showing image on plate.
3. Feature: entirely scrap by hand for the guild rail to meet the highest
precision in the world, 3 independent vacuum space design of the
drum to avoid plate fly off. Also the 405nm laser diode ensure the
good resource of laser.
The theory of CTcP named is starting from X-,channel decides the
name also,the end of the name means the type,thermal machine is
T,UV machine means U.For example,X-0322U means the 32channels laser
diodes CTcP machine.DOIE company pride customer with processor,CTP
machine,stacker,bridge,software. It achieves the integral workflow
Manual scrap by hand of the guild rail promise the highest
precision. Lead screw structure is very easy to operate,aslo easy
to clean and maintain.
DOIE CTP machine ueses start sensor and side guild technology
together to ensure the the loading plate center position,meanwhile
to improve the precision.
DOIE CTP machine has tested most of CTP or CTcP plates from market,
it can meet most plate demand.On the basis of the widely choosing
of plate, customer can easily reduce the cost and increase profit.

Worked as plate maker printing area,useing 405nm laser diode which
made in JAPAN for the core part of machine. To meet the demand of
different customers,DOIE company invent the bridge and stacker to
make one integral prepress printing workflow. This integral
workflow can easily and effectively to reduce cost of customer.
1: Guild rail chasis with most highest precision,V-Groop scrap by
hand scrap entirely.
· The chassis is integral becoming one with the guild
rail,effectively to imporve the stability and wear-resistance.
· The guiderail precision is very high wich can achieve
1-3μm/m,effectively ensure printing precision.
· Scraping guiderail is made by cast-iron material of the guiderail
achieves more stability, there is lubricant grease on the
guilderail surface to make a protective role;
· Using import soft guide pairs and precise grinder guiderail
technology, make optical platform move has little wear; the moving
of platform has better smooth, precision.
2. Totally Independent vacuum drum structure, effectively absorb
various plates,avoiding plate off.
· By using the three-cavity technology, the drum could effectively
absorb various plates, avoid the plate.
· According to different size of plate, adjust absorptive power,
could achieve best printing effect.
· Using negative pressure checking before printing, avoid the plate
· Using negative pressure checking in printing, avoid the plate
· Using negative pressure and prevent air leakage technology.
3. Continue feeding plate system, automatically loading and
· Advanced belt conveying plate system achieve continue feeding.
· Mechanical head clip automatic positioner is more stable and easy
· Using mechanical tail clip automatic positioner.
· Automatic negative pressure absorption technology.
4. High precision side-guide technology, improve printing
· Fusing advanced start sensor checking technology and side-guide
technology together to improve the printing repeatability
· High precision side-guide technology, making the equipment
running more stable.
· According to the requirement, increase dynamic balance data
automatically, make the production conveniently.
