CTCP Plates Manufacturers In China

 

CTCP (Computer To conventional Plate) plates are not a replacement or downgraded version of CTP plates, but a derivative form of Computer to Plate Technology (CTP), which utilizes conventional PS plates for computer to direct plate making. CTCP plate manufacturers are usually able to produce a wide range of specifications and types of CTCP plates to meet different printing needs. Common CTCP plate specifications include 0.15mm, 0.20mm, 0.25mm, etc., with different customisation options for sizes.

The production process of CTCP plates includes the following steps:

- Preparation of plate: Choose high-quality PS plate as the substrate, and make sure that its surface is flat and free of defects.

- Coating process: Coating a layer of photopolymer on the surface of the plate, which is the key to CTCP plate making. The coating process requires strict control of the amount of coating, uniformity and drying degree to ensure that the photopolymer can be firmly attached to the plate.

- Exposure Processing: Using computerised direct plate making equipment to expose the plate coated with photopolymer. During the exposure process, a computer-controlled light source will accurately expose the plate according to a predetermined pattern, so that the photopolymer will undergo a chemical reaction under the action of light.

- Developing: The exposed plate needs to be developed to remove the unexposed portion of the photopolymer to form the desired pattern and text.

- Subsequent treatment: After developing, the plate may also need to be dried, polished and other subsequent treatment to improve its printability and durability.

The quality control of ctcp plates manufacturer is carried out throughout the whole production process, mainly including the following aspects:

- Raw material control: Ensure that the raw materials such as PS plate and photopolymer meet the quality standards.

- Process control: Strictly control the operating parameters and conditions of coating, exposure, development and other processes to ensure stable and reliable product quality.

- Equipment maintenance: regular maintenance and repair of production equipment to ensure that the equipment is in good working condition.

- Inspection and testing: Strict inspection and testing are carried out during the production process and before the finished products leave the factory to ensure that the products meet the relevant standards and customer requirements.

CTCP plates have the following advantages over other plate making technologies:

- Lower cost: Since CTCP plate adopts traditional PS plate as the substrate, the cost is lower compared with dedicated CTP plate.

- Simplified process: CTCP plate making technology simplifies the steps of film and plate making in the traditional plate making process and improves the production efficiency.

- Easy to operate: CTCP plate making equipment is easy to operate, easy to master and use.

- Good compatibility: CTCP plate can be compatible with the existing printing equipment and process, without the need for large-scale equipment transformation and upgrading.

- Environmental protection and energy saving: CTCP plate making process does not require the use of a large number of chemicals and consumables, which is conducive to environmental protection and energy saving.

Overall, CTCP plate manufacturers are able to produce CTCP plates of various specifications, ensure stable product quality through strict production process and quality control, and have the advantages of high precision, high efficiency and environmental protection.
