Thermal transfer ink is a special type of ink used in the thermal transfer printing industry, and its basic components are pigments, resins, additives and soluble solvents. Thermal transfer ink heats the printing template at a high temperature to transfer the ink from the template to the surface of the product to be printed, thereby realizing the printing process. Thermal transfer ink has the characteristics of stability at high temperature, clarity of printed patterns, bright colors, etc., and it can be printed on a wide range of materials, including plastics, ceramics, metals, etc. Thermal transfer inks are widely used in daily necessities, clothing, electronic products and other fields.
Detection performance
The performance of thermal transfer ink can be tested and evaluated from different angles. Here are some performance types that may need to be tested and metrics that may need to be recorded:
| performance type | index |
|---|---|
| D | Clarity, color accuracy, gloss, adhesion of printed patterns |
| heat transfer effect | Transfer rate, transfer time, full cure time |
| Packaging material adaptability | The adaptability of ink in different materials and different temperatures |
| Packaging Durability | Durability, heat resistance, chemical resistance of packaging under different conditions |
| packaging cost | Packaging material usage, printing speed, ink cost |
Test Methods
The performance indicators that need to be tested depend on the specific application scenarios and requirements of the thermal transfer ink, so when testing, it should be selected and recorded according to actual needs. The following are commonly used test methods:
Printing effect test: Use a thermal transfer printing equipment to print according to standard test methods and requirements, and check and evaluate the printed matter. Aspects such as graphic clarity, color accuracy, gloss and adhesion are typically checked.
Thermal transfer effect test: Use standard test methods and equipment to test the thermal transfer effect of ink, including indicators such as transfer rate, transfer time and complete curing time.
Packaging material adaptability test: Apply thermal transfer ink to different packaging materials and test its adaptability under different temperature conditions.
Packaging Durability Test: Put the packaging under different conditions, such as high temperature, low temperature, humidity, chemicals, etc., to test its durability, heat resistance and chemical resistance.
Packaging cost test: record the usage of packaging materials and printing speed, calculate the cost of ink, etc.
Before testing, it is necessary to formulate a test plan and test process, clarify test objectives and indicators, select appropriate test equipment and methods, and record test results and data. After the test, it is necessary to analyze and evaluate the test results, propose improvement measures, continuously optimize and improve the performance of thermal transfer inks, reduce costs, and increase production efficiency.
