Violet-sensitive photopolymer plates is a high-tech material used in the printing industry, which is mainly used for transferring digital image information directly to the printing plate. Combining the excellent photopolymerization properties of violet photopolymer resin with the strength and stability of a metal substrate, this kind of printing plate is widely used in commercial printing, packaging printing and other high-precision printing fields, bringing higher precision, efficiency and environmental friendliness to the printing industry.

Technical features of violet-sensitive photopolymer plates:

1, Violet light technology:

As a light source, violet light plays a key role in the CTP plate making process. With high energy density and short wavelength, violet laser light source can realize high-precision image exposure and improve the resolution and clarity of printing plates.

Violet light source also has better safety performance, such as violet laser system's safety light is usually yellow, compared with other light sources more convenient to operate and manage.

2, Photopolymerizing resin material:

Photopolymerizing resin is a special material that can react chemically under light to form the desired image. In violet photopolymer CTP plates, the photopolymerized resin, as the main component of the plate, has good sensitivity to violet light.

The photopolymerizing resin material has excellent imaging properties and physical properties that ensure high precision and durability of the printing plate.

3, Metal plate base:

Compared to traditional paper or plastic plate bases, metal plate bases have higher strength and stability, and are able to withstand greater printing pressures and a longer service life.

Metal plates also improve the thermal conductivity of the plate, which helps to better control the temperature during the plate making process and improve the quality of the plate.

Characteristics of violet-sensitive photopolymer metal plates are:

1. High resolution: Violet photopolymer metal printing plate can realize very high resolution, suitable for detailed patterns and text printing.

2. fast imaging: through CTP technology, digital files can be quickly converted into printing plates, shortening plate-making time and improving production efficiency.

3. Excellent image quality: the pattern formed after exposure is clear, sharp edges, and can maintain high-quality printing results.

4. Abrasion and chemical resistance: the cured resin layer has good abrasion and chemical resistance, suitable for long time use.

5. Environmentally friendly: Many violet-sensitive photopolymer printing plates are made of environmentally friendly materials, reducing dependence on harmful chemicals.

Application areas of violet-sensitive photopolymer plates:

- Commercial Printing: Used in the printing of books, magazines, brochures, etc.

- Packaging Printing: Widely used in food packaging, pharmaceutical packaging and other fields.

- Label Printing: Used for product labels and signs.

- Art Printing: Suitable for reproduction and printing of high quality art works.

When choosing a violet-sensitive photopolymer metal printing plate, consider the following factors:

1. Compatibility: Ensure that the selected printing plate is compatible with existing CTP equipment and presses.

2. Photographic characteristics: different printing plates have different photographic sensitivities and need to be selected according to the specific workflow.

3. Thickness and size: according to the requirements of the printing machine to select the appropriate thickness and size of the printing plate.

4. Post-processing requirements: Understand the post-processing processes such as curing and developing in order to obtain the best printing results.

Violet-sensitive photopolymer plates play an increasingly important role in the modern printing industry, and through advanced technology and material innovation, they continue to improve printing quality and production efficiency. Choosing the right printing plate and process can significantly improve the quality and market competitiveness of printed products.
