724*615*0.30mm Double Layer Thermal CTP Positive Printing Plate
The 7246150.30mm Double Layer Thermal CTP Positive Printing Plate is a state-of-the-art plate designed for Computer to Plate (CTP) thermal printing applications, primarily used in commercial and packaging printing industries. Engineered for superior performance and reliability, this printing plate ensures high-resolution graphics, durability, and excellent printing stability in positive image imaging.
This printing plate features a double-layer coating technology, which significantly improves the thermal sensitivity and robustness of the plate during exposure and development phases. The 0.30mm thickness provides optimal rigidity to sustain high-volume runs without deformation, while the dimensions 724*615mm accommodate a broad spectrum of printing machines.
Features
- Double Layer Thermal Coating: Enhances sensitivity and plate life for high-volume prints.
- Positive Working: Optimized for positive processing; areas exposed become ink-rejecting.
- High Resolution: Supports line screens up to 300 lpi for crisp text and fine graphics.
- Chemical Resistance: Suitable for conventional lithographic inks and dampening solutions.
- Sustainable Use: Reduced chemical consumption due to the efficient coating and processing methods.
Applications
The 7246150.30mm Double Layer Thermal CTP Positive Printing Plate is ideal for:
- Commercial sheetfed and web printing
- Packaging printing for labels, folding cartons, and flexible packaging
- High-fidelity image reproduction requiring precise dot control
- Long-run printing tasks where plate durability is critical
