Huaguang Thermal CTP Edition Technical Features and Applications (2)

Safe operating conditions: within 60 minutes under white fluorescent light; no more than 12 hours under yellow safety light, it is safe. Of course, if you do not use the best, or according to the original package.

Storage conditions: Protected from light, the temperature is not higher than 24°C, and the relative humidity is not more than 60% for 18 months. Processing conditions are shown in Table 2.

Third, Huaguang TN thermal CTP version of the technical characteristics

1. The exquisite color prints of high-grade aluminum base require detailed and uniform sand, which requires a high-strength aluminum plate base with a fine surface on the surface of the base plate as a support. Huaguang CTP version is now fully imported high-quality CTP plate special aluminum production TN thermal CTP version.

2. Surface roughening

In the advanced large-scale roll-type continuous PS plate production line, the advanced electrolytic oxidation process is used to chemically treat the aluminum base to form layers of fine and uniform sand layers.

Electrolytic and oxidizing fluids are automatically detected and automatically supplemented to ensure uniformity in the surface treatment of the aluminum plate base.

3. Link layer

In order to improve the fastness of the bonding between the heat-sensitive resin layer and the aluminum base, it is ensured that the product has a high resistance to the printing force. After the graining treatment, a tie layer is first applied on the base.

4. Coating a resin layer with good thermal sensitivity

Huaguang TN thermal CTP plate is based on the new principle of thermal acid-activated crosslinking imaging. A series of new functional resins have been synthesized and screened to select the best combination, so that the plate has a good thermal performance.

5. Spectral absorption band of thermosensitive resin layer

Huaguang TN thermal CTP plate uses special photothermal conversion materials to ensure that the plate absorbs heat energy with high efficiency and bright room operation performance.

6. Good dot reproducibility

The TN type thermal CTP plate has a certain threshold value. When the exposure dose received does not reach the exposure threshold, the resin in the resin layer will not react, and the cross-linking reaction occurs only when the threshold value is reached. The edge of the edition is very sharp, and the graphic and video images are clearly structured, delicate, with less dot expansion, and the ink has good adaptability and rich color.

7. Has good ink affinity

The thermal layer of TN type thermal CTP plate uses a special functional resin and a special ink additive. Therefore, the printing plate made with this version has excellent ink-receptive performance and fast ink balance function.

8. Plate printing force is high

Huaguang TN thermal CTP plate coating has excellent wear resistance due to the selected resin. Therefore, the printing plate is resistant to high printing force. Plates made under the recommended use conditions are resistant to 150,000 impressions and roasted. After the version up to 1 million India.
