1325mm Offset Printing Positive Thermal CTP Plate

Our 1325mm Offset Printing Positive Thermal CTP Plate is designed for commercial printers that need dependable image quality, efficient plate making, and stable offset press performance. As a professional printing plate manufacturer, we produce positive thermal CTP plates with carefully treated aluminum bases and consistent thermal coatings to support clear, accurate printing results.

What Is a Positive Thermal CTP Plate?

A positive thermal CTP plate is an offset printing plate imaged by a thermal CTP machine. During imaging, the laser exposes the non-printing areas of the plate coating. After development, the image areas remain on the plate and accept ink during printing, while the non-image areas hold fountain solution.

This plate type is widely used by commercial printing companies because it offers reliable image reproduction, clear dots, and stable performance on press.

How It Works (Positive-Working Process)

1.Laser Exposure: When the thermal laser hits the plate's photosensitive blue coating, it alters the chemical structure of the exposed areas, making them soluble in an alkaline developer.

2.Development: During processing, the exposed coating washes away, revealing the hydrophilic (water-loving) aluminum base.

3.Image Area: The unexposed coating remains intact, hydrophobic (ink-receptive), and forms the actual image area used to transfer ink onto paper.

Why Choose Our 1325mm Thermal CTP Plate?

The 1325mm width is suitable for many medium- and large-format offset printing applications. We manufacture our plates to help printers maintain quality throughout plate making and production printing.

Clear Image Reproduction

Our positive thermal CTP plates support sharp text, smooth gradients, fine lines, and detailed image reproduction. They are suitable for printing work where consistent visual quality matters, including brochures, books, magazines, catalogs, and packaging materials.

Stable Press Performance

A stable plate helps reduce interruptions during printing. Our thermal CTP plate coating is designed to provide dependable ink-water balance, helping operators achieve a smoother production process and more consistent printed sheets.

Strong Aluminum Base

We use quality aluminum base material with controlled graining and anodizing treatment. This structure supports good water retention in non-image areas while helping the image areas perform reliably during offset printing.

Efficient Plate Making

The 1325mm positive thermal CTP plate works with compatible thermal CTP systems and standard plate processing workflows. It enables printers to move from digital file to printing plate efficiently, reducing the steps associated with conventional film-based plate making.
