introductory:
In today's increasingly environmentally conscious and thriving printing industry, the choice of ink is crucial. With its unique advantages, ordinary economical offset printing inks occupy an important position in the printing field. It has bright colors and can accurately restore the color of the pattern; Good adhesion, making the printed matter durable; The drying speed is moderate, which effectively improves the printing efficiency. Whether it is a book or magazine, or a commercial poster, ordinary offset printing inks play a key role. Let's dive deeper into its benefits and applications.
1. What is ordinary economic offset printing ink
Ordinary economic offset printing ink is a type of ink commonly used in offset printing, which is mainly composed of pigments, binders, fillers and auxiliaries. The pigment gives the ink its color, and the binder is the key component of the ink, which acts as a binder to the pigment and allows the ink to be transferred to the substrate during the printing process. Fillers can adjust some of the physical properties of inks, and auxiliaries are used to improve the printability of inks, etc. It has the characteristics of relatively low cost and can meet the general printing needs, and is widely used in the printing industry.
2. the working principle of ordinary economic offset printing ink
The working principle of ordinary economy offset printing inks is based on the basic principles of offset printing. In the offset printing process, the graphic part and the blank part on the printing plate are distinguished by different physical and chemical properties. The ink is first transferred to the graphic part of the printing plate, and due to the principle of incompatibility between oil and water, the blank part will not adsorb the ink. The printing process is then completed by transferring the ink from the plate to a substrate (such as paper) via blanket. In this process, the viscosity and drying speed of the ink have an important impact on the printing quality.
3. the use of ordinary economic offset printing ink
Preparation before printing: Before using ordinary economic offset printing inks, it is necessary to ensure that the printing equipment is clean and free of other inks or impurities. According to the requirements of the printing task, select the appropriate color and type of ink, and check whether the performance of the ink meets the requirements.
Ink blending: If you need to mix colors, you should accurately mix different colors of ink according to a certain ratio. At the same time, according to the specific situation of printing, such as printing speed, paper type, etc., auxiliary agents can be added appropriately to adjust the viscosity and drying speed of the ink.
Printing on the machine: Add the prepared ink to the ink fountain of the printing machine, adjust the ink volume and printing pressure and other parameters, and start printing. In the printing process, it is necessary to pay close attention to the transfer of ink and printing quality, and make adjustments in time.
4. how to store ordinary economic offset ink
Storage environment: Ordinary economic offset printing inks should be stored in a cool, dry and well-ventilated environment, avoiding direct sunlight and high temperatures. The storage temperature is generally recommended to be between 5°C-25°C, and the relative humidity is maintained at 40%-60%.
Packaging sealing: The packaging of the ink should be well sealed to prevent the ink from oxidizing and drying out in contact with the air. If the ink barrel is not used up after opening, the lid of the barrel should be tightened in time and used up in a short time as soon as possible.
Classified storage: Different types and colors of inks should be stored separately to avoid confusion. At the same time, care should be taken to store the ink separately from other chemicals to prevent chemical reactions.
5. the advantages of ordinary economic offset printing ink
Cost advantage: The production cost of ordinary economic offset printing ink is relatively low, which is an economical choice for some printing enterprises that are more sensitive to cost.
Good printability: It has a moderate viscosity and drying speed, can print smoothly on different types of printing equipment, and can adapt well to different paper and printing conditions.
Color expressiveness: Although it is an ordinary economic type of ink, it can still provide richer colors to meet the color needs of general printed matter, such as ordinary books, brochures, etc.
Wide applicability: It can be used for many types of printing, whether it is text printing or image printing, it can achieve good results, and is suitable for different printing processes and substrates.
6. the applicable scene of ordinary economic offset printing ink
Book printing: In the field of book printing, ordinary economic offset printing inks are widely used in the body and cover printing of books and magazines. It can meet the requirements of clear text and good color reproduction, and at the same time, the cost is low, and it is suitable for large-scale book printing production.
Commercial printing: such as leaflets, posters, product manuals and other commercial prints, ordinary economic offset printing inks can also give full play to their advantages, achieve better printing effects at a lower cost, and meet the publicity and promotion needs of enterprises.
Packaging and printing: For some packaging and printing that have high cost requirements and are not particularly demanding on printing quality, such as ordinary carton and carton printing, ordinary economic offset printing ink is a commonly used choice.
7. The development prospect of ordinary economic offset printing inks
With the continuous development of the printing industry and the increasing requirements of environmental protection, ordinary economic offset printing inks are also facing new opportunities and challenges. On the one hand, in order to meet the needs of environmental protection, the research and development of more environmentally friendly ordinary economic offset printing inks will become a trend, and the application of environmentally friendly inks such as water-based offset printing inks may gradually increase. On the other hand, with the continuous progress of printing technology, the performance requirements of ink will be higher and higher, and ordinary economic offset printing inks need to be continuously improved and innovated to improve their color expression, printability and other properties to adapt to market changes. At the same time, in some cost-sensitive printing fields, ordinary economic offset printing inks will still occupy an important position, and its market demand will remain stable for a certain period of time.
