Gravure ink is a very important raw material for plastic flexible packaging color printing. The perfect presentation of product colors comes from the performance of the ink itself and the correct typesetting printing. When purchasing inks, companies will consider a variety of factors such as performance, color density, printability, price, and environmental protection. How to properly and correctly choose the ink that best suits the conditions of the company is in the purchasing department of the company. important topic.
I. Basic competence requirements for flexible packaging buyers
To purchase the most cost-effective inks, first of all, we need a professional buyer.
Buyers must first have certain professional knowledge. They need to know the basic performance of the ink, the company's own customer product structure requirements, the performance of the company's own equipment and the skill level of the employees, and also understand the product quality and business of the ink supplier in the market. Image, corporate strength, etc.
Second, the procurement principle
1.Purchase different types of inks according to the product structure of the enterprise
The main categories of inks for the flexible packaging market are benzene composite inks, benzene surface printing inks, benzene-free and ketone-free chlorinated polypropylene inks, benzene-free and ketone-free polyurethane inks, and alcohol-soluble acrylic inks. At present, the competition of inks in the flexible packaging market is very fierce. In some regional markets, prices are still used as the key marketing method. In fact, this is very undesirable, and it is also the lastest marketing method in marketing. Ink suppliers should focus on thinking. It's quality and service, not price. Price is not the most important factor in the entire marketing model. Similarly, when choosing flexible inks for flexible packaging companies, they should consider more about the performance of the inks, the ink technology strength of the suppliers, and the professionalism and complete continuity of after-sales service. When selecting ink, first choose according to the product structure of the enterprise, as shown in Table 1:
Table 1: Suitable ink types and procurement directions for different structures
2.Select ink according to equipment
After clearly identifying the positioning of the company's product structure, we then select the appropriate ink supplier based on the overall state of the equipment, and then cooperate with the printing technicians to make some evaluations of the ink technology and make a decision. Especially with regard to the transition direction of the ink, the relationship between the existing operation methods and the operation of the transition ink should be analyzed, as shown in Table 2.
Table 2: Ink selection based on equipment
Third, screening ink suppliers
After doing the above analysis, the purchasing department knows which inks can meet the requirements of the enterprise, and can start to find ink suppliers that meet the requirements.
We usually know which ink suppliers are through magazine advertisements, friend recommendations, ink salesperson self-recommendation, and tendering. When purchasing inks, we focus on the following aspects: the size of the supplier, the commercial reputation of the supplier, and the market. Feedback from quality customers, value for money, etc.
Before the product of the ink supplier is officially tried out, the ink supplier must first report the company's overall information to the flexible packaging company for record review, and then according to its information, the flexible packaging company is better to visit the supplier site to understand. Focus on inspecting the production process monitoring and quality management of ink companies. Really outstanding suppliers are welcome to inspect, which is also the basis for establishing a good and long-term cooperative relationship.
Fourth, trial ink
After obtaining the procurement qualification, we usually have to conduct a trial, as shown in Table 3.
Table 3: Ink trial steps
In this sample link, our enterprise purchasing department or technology department, quality control department, and production department must do a good job of the sample product quality, printing data, and product process data, which can provide data for subsequent ink quality tracking. This is used to check the quality stability of the supplier's products. During the sample period, we recommend that the technical service personnel of the ink supplier communicate with the production and technical personnel of the enterprise throughout the process. If the prenatal ink operation and knowledge training can be achieved, the correct and standardized use of ink will have some impact on the overall skills of flexible packaging companies. Promotion will be a win-win situation for ink suppliers and enterprises.
Table 4: Application Form for Ink Samples of Flexible Packaging Enterprises (see table below)
After the sample link is completed, the technical department, quality control department, production department and purchasing department of the flexible packaging enterprise shall conduct on-site inspections of the production and quality of the supplier enterprise, analyze and evaluate the data of the sample, and evaluate the overall quality of the printed sample and ink. Evaluate the printing adaptability, understand the customer's feedback on the sample, etc., summarize some of the problems in printing, and report to the ink supplier for improvement. The improved ink will then be tested in the above way, to be in line with the company's quality After the standard, a comprehensive summary is made and signed to determine the final entry qualification of the ink supplier. There is one more point that we should pay attention to: the calculation of the comprehensive cost of the ink is also a very critical point in our final selection of the ink supplier.
After confirming the supplier, we began to enter into the contract communication and signing phase. This phase mainly involves the supply and payment methods of the goods, and the establishment of the supplier's after-sales service. Most of the qualified ink companies have their after-sales technical service departments, but many of them are not perfect. In this regard, ink suppliers need to improve their technical level, integrate service teams, and perform professional operations and services. This is also what many flexible packaging companies need at present.
Proper and reasonable selection of ink is the most critical first link in the production process of flexible packaging enterprises. It determines the printing effect of the company's products, determines the degree of product packaging acceptance by customers, and also determines the packaging image and technical strength of the company. Proper and reasonable selection of ink is the beginning of the entire production cost accounting, which determines the important cost proportion in the production cost accounting. In the overall ink procurement process, the sample is the final basis of the procurement department. We recommend quantification in this regard to highlight the ink supplier's ink performance and printing adaptability, and finally confirm the purchase direction of the ink.
