Embodiment Construction

[0023] The technical solution will be described in detail below through a best embodiment, but the protection scope of the present invention is not limited to the embodiment.

[0024] A method for manufacturing a negative CTCP plate without processing, comprising the following steps:

[0025] 1) Alkali cleaning: first select high-quality aluminum plate base, in the temperature range of 70-80 ℃, add 12% sodium hydroxide and 10% sodium carbonate to the alkali cleaning tank Alkali washing is carried out on the selected aluminum base, and the alkali washing time is controlled within the range of 0.5-1h, and then cleaned with water;

[0026] 2) Neutralization: on the basis of step 1), neutralize with 18-20% dilute acetic acid solution, and control the neutralization time within the range of 0.5-1h, and then wash with water;

[0027] 3) Electrolytic deashing: on the basis of step 2), electrolyze the aluminum plate substrate three times in an electrolytic cell containing 12-15% hydr...

Abstract

The invention discloses a manufacturing method of a treatment-free negative image CTCP plate, wherein the manufacturing method comprises ten steps such as alkali washing, neutralization, electrolysis-ash removal, oxidation, pore sealing, water washing and drying, coating, secondary drying, exposure imaging, cutting, and inspection packaging. According to the present invention, the obtained productcan be directly fed to the printing machine so as to be subjected to exposure imaging printing without the adding of any chemical reagents and the developing, and is suitable for UV ink printing, wherein the UV-resistant ink has characteristics of wear resistance, weather resistance, corrosion resistance and the like; and the method has advantages of high sensitivity, fast development, high printing rate and low cost, and cannot generate a large amount of wastewater and residue polluting the environment so as to easily achieve environmental protection.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a method for manufacturing a negative CTCP plate without processing. Background technique [0002] The traditional CTCP plate is a positive plate, which wastes a lot of photosensitive adhesive. It needs to be washed with a large amount of developer. The developer contains a lot of alkali, surfactant, inorganic salt and other substances. The recycling cost is high and it cannot effectively protect the environment. [0003] Therefore, in the prior art, a large amount of developing solution is required to be washed, the cost is high, and the environment cannot be effectively protected. Designing a process-free negative CTCP plate manufacturing method is a technical problem that needs to be solved at present. Contents of the invention [0004] Purpose of the invention: Aiming at the defects and insufficiencies of the prior art, to solve the problems of needing a large amount of de...
