CTCP (Computer-To-Conventional Plate) is a digital pre-press technology that outputs computer-generated digital files directly to traditional CTP (Computer-To-Plate) plates, eliminating the need for traditional printing film platemaking and improving printing efficiency and quality.

CTCP plate is a kind of photo-sensitive plate specially used in printing industry. Through CTCP technology, the electronic file is directly exposed on the surface of the plate to form the image of the printing plate, which is used in traditional printing process.

The specification, thickness and size of CTCP plate will be different according to the specific printing equipments and requirements, common specifications include: 420mm, 520mm, 650mm on the long side, etc.; the thickness is usually between 0.15mm and 0.40mm; the size can be customized according to the requirements of the specific printing machines.

CTCP plates are mainly divided into two types: traditional photopolymerized plates and heat-sensitive plates. Traditional photopolymerized plates require chemical development treatment, while heat-sensitive plates are developed directly by heat-sensitive materials without chemical treatment, which is more environmentally friendly.

The quality requirements of CTCP plates include flatness, surface smoothness, photosensitive speed and photosensitive stability. High-quality CTCP plates should have good photosensitive performance and printing stability to ensure the accuracy and stability of printed materials.

Advantages in printing: CTCP plates have the following advantages over traditional printing plates:

- Digital production: CTCP technology realizes digital pre-press processing, which reduces human operation and traditional plate making process and improves printing efficiency.

- High-precision printing: CTCP plates have excellent photosensitive performance and stability, which can realize higher-precision printing effects and improve printing quality.

- Environmental protection and energy saving: Heat-sensitive CTCP plates do not require chemical development, which reduces chemical waste liquid emissions and is more environmentally friendly and energy-saving.

Overall, CTCP plate is a digitalized, high-efficiency, high-quality printing plate with excellent printing effect and environmental advantages, and is widely used in the printing industry. When choosing CTCP plates, you need to choose the right specification and type according to the specific printing equipment and needs to ensure the printing quality and effect.
