Problems solved by technology

[0003] 1. The decay is fast. When used on the traditional PS plate, due to the low requirement for dot reduction, it can be compensated by increasing the temperature of the developer or prolonging the development time. However, for the high-definition UV-resistant ink UV-CTP plate, the parameters of the change It is unacceptable to bring inconsistent results. If the frequency of changing the developer is increased, it will increase the labor intensity of the operator and delay time;
[0004] 2. It is easy to scale on the developing equipment. The scaling of the circulation pipeline will cause the flow to decrease. The scaling of the brush will affect the renewal of the liquid on the layout. In severe cases, the scaling will scratch the layout, and the scale that falls off will crush the layout;
[0005] 3. It is easy to crystallize in winter. When it is poured out of the barrel, part of the crystallization will remain in the barrel, causing the composition of the developer to change.

Embodiment 1

[0016] Example 1: Alkaline main agent: 3.0kg, solubilizer: 0.3kg, penetrating agent: 0.2kg, alkaline regulator: 15kg, coating protection agent: 0.001kg, water: 81.499kg to prepare 100kg of UV-resistant ink UV-CTP version developer.

Embodiment 2

[0017] Example 2: Alkaline main agent: 35kg, solubilizer: 10.0kg, penetrating agent: 8.0kg, alkaline regulator: 0.5kg, coating protection agent: 3.0kg, water: 43.5kg to prepare 100kg of UV-resistant ink UV-CTP version developer.

Embodiment 3

[0018] Example 3: Alkaline main agent: 19kg, solubilizer: 5.1kg, penetrating agent: 4.1kg, alkaline regulator: 7.8kg, coating protection agent: 1.5kg, water: 62.5kg to prepare 100kg of UV-resistant ink UV-CTP version developer.

[0019] The above materials were stirred, dissolved and filtered, and the tank body (33.8 liters) of Hu.q PT-90 developing machine was filled with Examples 1, 2, and 3 respectively, and the temperature was circulated to 25°C, and the developing time was set to 25 seconds. The UV-CTP plate coating of UV-resistant ink prepared in Examples 1, 2, and 3 is centrifugally coated on a surface with a roughness Ra of 0.38-0.4 μm and an oxide layer quality of 2.0-3.0 g / m2, which has been sealed. On the 1050 aluminum plate base, after drying at 137°C for 2 and a half minutes, take a 465mm×380mm format, and image it on the Kelei UVP-3324GX+ laser platemaking machine, develop in the above-mentioned prepared developer at 25°C for 25 seconds, and test the dots with iC...

Abstract

The invention relates to a UV ink-resistant UV-CTP plate developer. The UV ink-resistant UV-CTP plate developer is characterized by comprising the following raw materials in percentage by mass: 3%-35% of an alkaline main agent, 0.3%-10% of a solubilizer, 0.2%-8% of a penetrating agent, 0.5%-15% of an alkaline regulator, 0.001%-3% of a coating protective agent and 30%-95% of water. By adopting the technical scheme, according to the UV ink-resistant UV-CTP plate developer provided by the invention, the declination is slow, the UV ink-resistant UV-CTP plate developer is not easy to scale, and crystal is not easily generated in a low-temperature environment.

Description

technical field [0001] The invention relates to a developer, in particular to a UV-resistant ink UV-CTP plate developer. Background technique [0002] UV-resistant ink UV-CTP plate is a kind of offset printing plate that uses 405nm laser for imaging. Due to its convenient production, moderate cost and convenient use, it can be used for UV ink printing, and it can be used directly without baking in packaging UV printing. . UV-resistant ink UV-CTP plate developer is an essential consumable for the use of UV-resistant ink UV-CTP plate, but most of the developers on the market are traditional PS plate developers. Its disadvantages are: [0003] 1. The decay is fast. When used on the traditional PS plate, due to the low requirement for dot reduction, it can be compensated by increasing the temperature of the developer or prolonging the development time. However, for the high-definition UV-resistant ink UV-CTP plate, the parameters of the change It is unacceptable to bring inco...
