DOIE UV-CTP 48 channels uses the most advanced and stable guide
rail technology, using automatic loading way and 405nm laser diode,
digital process workflow, high precision dot, low cost UV(CTcP)
plates, reducing the cost.
DOIE UV-CTP uses special laser diode and external drum design, to
ensure the biggest energy transfer efficiency and exposure
We use reliable control circuity system.By using control method of
negative feedback, the circuitry achieve constant-current control,
DA output power adjust continuously, LD output follow control
signal, which output pulse by using on-off mode, therefore the
standby power is low.
Also with ultrahigh frequency MOS pipe and high speed operational
amplifier made the voltage pulse rise and fall time on the LD
CTP platemaking machines generally divided into inside drum, the
drum type, plate type, curve type four major categories. In the
four types at present, the most use is the internal drum and the
drum; The performance with most high-grade CTP platemaking machines
are the drum type.
Worked in pre-press printing process, it can be used to connect
with bridge and stacker to make up an integral pre-press
workflow,which will improve production efficiency and reduce labour
cost. UV-CTP can fit the conventional plate whose cost is lower
than thermal plate. That is why UV-CTP will be the main stream
pre-press equipment in future development.
1. Precise guiderail chassis. Manual entire scrape.
- The chassis is HT300 inblock cast, guiderail and chassis became in
one, the high mechanical strength, the high heat stability, less
possibility of deformation.
- The guiderail precision could achieve 1-3μm/m,effectively ensure
- Scraping guiderail is made by cast-iron, the surface has one thin
oil slick, play an lubricant, 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. Independent vacuum structure, effectively absorb various plates.
- 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, achieve automatic loading plate.
- Using advanced belt conveying plate system.
- Using mechanical head clip automatic positioner.
- Using mechanical tail clip automatic positioner.
- Using automatic negative pressure absorption technology.
4. High precision side-guide technology, improve printing
- Fusing advanced plate-edge checking technology and side-guide
technology, improving the printing repeatability precision.
- High precision side-guide technology, making the equipment running
- According to the requirement, increase dynamic balance data
automatically, make the production conveniently.
