Working principle and advantages analysis of CTP plate making machine

1、 CTP working principle
Digital file input
Receive digital files such as PDF and PS generated by design software (such as Adobe Illustrator and InDesign), and convert them into high-precision dot data through RIP (raster image processor).
Plate exposure imaging
Laser technology: using infrared laser (thermal sensitive) or purple laser (photopolymerization) and other light sources to accurately expose the surface of the printing plate based on graphic and textual data.
Thermal version: Laser heating causes a chemical reaction in the coating, forming an oleophilic graphic area.
Photopolymerization version: UV laser triggers polymerization reaction to generate graphic and textual parts with high printing resistance.
Precise positioning: The movement of the laser head is controlled by a high-precision servo motor to ensure the accuracy of the dot restoration (such as 2400dpi or above).
Post processing of printing plates
Part of the plate material needs to be developed (chemically or treated with water) to remove the unexposed parts, and after drying, it can be printed on the machine.
2、 The core technological advantages of Chuangda CTP
High precision imaging system
Using imported lasers and optical components, it supports 1% -99% dot reduction, with a minimum dot diameter of ≤ 10 μ m, ensuring fine printing layers.
Intelligent automation design
Automatic up and down plate, laser energy calibration, focal length adjustment and other functions reduce manual intervention, and the plate making speed can reach 30 sheets per hour (for double-sided).
Strong compatibility of plate materials
Supports thermal sensitivity UV、 Mainstream printing materials such as photopolymerization are suitable for different printing needs (such as commercial printing and thick packaging).
Green and environmentally friendly
Low energy consumption design, some models support chemical free plate materials to reduce waste liquid emissions.
3、 Value created for customers
Reduce cost and increase efficiency
Save film costs and processing time, shorten plate making cycle by 70%, suitable for short version fast printing orders.
The printing plate has a printing capacity of over 200000 prints (such as thermal plates), reducing downtime during plate changes.
Improve printing quality
The network points are sharp and distortion free, supporting FM screening to achieve high fidelity color reproduction.
Long term service support
Chuangda provides 24-hour technical response, regular equipment maintenance, and operation training to ensure customers' sustained profitability.
4、 Application scenarios
Commercial printing: reproduction of fine network points for picture books and magazines.
Packaging printing: spot color printing, precision control of thick cardboard registration.
Newspaper printing: high-speed plate making (100+split sheets per hour).
