Description

Technical Field

[0001] The invention belongs to the field of printing materials, and in particular relates to a novel Van Dyke glass printing material and a preparation process thereof. Background Art

[0002] As a classical photographic process based on iron salts, Van Dyck printing has gradually exposed many defects in the course of its historical development, which has greatly limited its application and promotion.

[0003] In terms of durability, early Van Dyck prints were made on paper, but the physical and chemical properties of paper make it difficult to maintain a stable state for a long time. As time goes by, paper is easily affected by environmental factors such as light, humidity, and temperature, and fades, turns yellow, and becomes brittle, making it impossible to preserve prints for a long time. This makes this process gradually lose its appeal among users who pursue the long-term value of their works, and its popularity has dropped significantly.

[0004] In terms of production costs, the materials required for Van Dyck printing are relatively special. The production and supply of these special materials often involve high costs. Both the purchase of raw materials and subsequent processing require a lot of money. This undoubtedly increases the cost of the entire production process, making many potential users discouraged due to economic factors, limiting the widespread popularity of this process.

[0005] In terms of operational convenience, the Van Dyke process has a very short shelf life. To ensure the printing effect, the user must dispense the medicine on site, and the prepared medicine must be used immediately. This immediate operation requirement not only puts great pressure on the user's time arrangement, but also requires them to have high professional knowledge and operating skills, which is difficult for ordinary users and seriously affects the operability and practicality of the process.

[0006] In summary, these drawbacks of the traditional Van Dyck printing process urgently require a new process to overcome them, so as to promote the continued development and application of this process in modern society. Summary of the invention

[0007] The purpose of the present invention is to provide a new type of Van Dyke glass printing material and its preparation process, aiming to solve the problems existing in the above-mentioned background technology. To achieve the above-mentioned purpose, the technical solution adopted by the present invention is:

[0008] A new Van Dyke glass printing material comprising gelatin, ammonium ferric citrate, tartaric acid, silver nitrate, potassium alum, fillers and water.

[0009] Preferably, it comprises 5-40 parts of animal gelatin, 3-6 parts of ammonium ferric citrate, 0.2-2 parts of tartaric acid, 1-10 parts of silver nitrate, 1-10 parts of potassium alum, 0.1-1 parts of filler and 10-100 parts of water.

[0010] Preferably, the bulking agent is thymol.

[0011] Preferably, the preparation method is as follows:

[0012] S1: Take 5-40g of animal gelatin and add 170ml of water to swell for 3-5 minutes;

[0013] S2: Mix 3-6 grams of ammonium ferric citrate with 500 ml of water to form liquid A;

[0014] S3: Take 0.2-2 grams of tartaric acid and mix it with 50 ml of water to make liquid B;

[0015] S4: Take 1-10 grams of silver nitrate and mix it with 50 ml of water to make liquid C;

[0016] S5: Take 1-10 grams of potassium alum and mix it with 80 ml of water as a replenisher;

[0017] S6: Take 0.1-1 g of thymol as a filling agent;

[0018] S7: Set the temperature of the expanded animal gelatin to 90 degrees on a magnetic stirrer with a heating function and stir and dissolve it at 300 rpm per minute, then pour liquid A into the completely dissolved animal gelatin and stir and mix at 300 rpm, add liquid B at 300 rpm after complete mixing, and then continue to add liquid C at 300 rpm, when liquid ABC and animal gelatin are completely mixed, add 15-30 ml of potassium alum solution, and then add 1-10 grams of thymol and stir and mix at 300 rpm;

[0019] S8: The mixed reagents are matured at 30 degrees Celsius for 2 hours to obtain a working solution.

[0020] Beneficial effects of the present invention:

[0021] Precise color tone control: This invention has successfully overcome the long-standing technical difficulty of achieving uniform color tone in paper printing. Through a unique material formula and process design, it can stably present a unique brown and white tone. This retro and artistic tone is highly consistent with the creative concept of artistic photography and personalized works, providing creators with a new and highly expressive visual language, which helps them better convey the emotions and themes of their works.

[0022] Convenient and efficient operation: Aiming at the pain point of extremely short retention period of paper prints, the present invention has been comprehensively optimized. The new process design makes the operation process simple and easy to understand. Users do not need to rely on complex professional equipment and superb operating skills, which greatly reduces the threshold for participating in Van Dyck print creation. This improvement enables more people to easily participate in the creation, laying a solid foundation for the widespread dissemination and application of this process.

[0023] Excellent storage performance: The traditional Van Dyke process has serious defects in storage, and problems such as short storage time and cumbersome user operation have always plagued the development of the industry. The present invention successfully solves these problems through innovations in materials and processes. It significantly extends the service life of printing materials, simplifies the storage and use procedures, and greatly improves the dissemination of the process, allowing more people to have the opportunity to contact, understand and use the Van Dyke printing process.

[0024] Green environmental protection concept: With the increasing awareness of environmental protection, this invention has shown obvious environmental protection advantages compared with modern photographic technology. The materials used will not produce harmful chemical waste liquid during the entire production process, effectively reducing pollution to the environment. This not only meets the pursuit of green and sustainable development in modern society, but also provides a more environmentally friendly and healthy direction for the future development of photographic technology.
