Inkjet digital photo paper is mainly used as the raw material for inkjet printing. Glossiness is an important indicator of the quality of inkjet digital photo paper, which directly determines the quality of printed products. So, what are the requirements for the glossiness of inkjet digital photo paper? How to measure it? This article introduces the requirements and measurement methods for the glossiness of inkjet digital photo paper.
Inkjet digital photo paper
With the continuous development of inkjet printing technology, inkjet printing has rapidly become popular due to its advantages of high image precision, bright colors, and environmentally friendly and pollution-free printing process. It has been widely used in the image output field. As one of the main consumables of inkjet printing, inkjet digital photo paper has also developed rapidly. However, with the continuous improvement of people's material living standards, consumers have higher and higher requirements for the quality of inkjet printing image output. The glossiness of inkjet digital photo paper is one of the main factors that determine the quality of printed products.
The glossiness of inkjet digital photo paper depends on the smoothness of the coating surface. The smoother the coating surface, the higher the reflectivity of the incident light on the ink-absorbing layer surface, and the higher the glossiness of the inkjet digital photo paper. There are two main factors that affect the smoothness of the coating: the particle size of the ink-absorbing pigment and the leveling property of the coating liquid. The smaller the particle size of the ink-absorbing pigment particles in the ink-absorbing layer and the narrower the distribution peak width, the higher the glossiness of the inkjet digital photo paper. This is because small-sized pigments have the ability to fill irregular coating surfaces and provide a smooth surface that is more closely in contact with the air interface. The incident light is reflected on the smooth surface, so that the inkjet coating has a higher glossiness. The better the leveling property of the coating liquid, the higher the surface smoothness formed during the drying process, and the higher the glossiness.
Gloss Measurement of Inkjet Digital Photo Paper
There are many indicators for evaluating the quality of inkjet prints, and the glossiness of the printed surface is one of the most important parameters. The glossiness of a printed product refers to the degree to which the reflectivity of the printed surface to incident light is close to the reflectivity of a complete mirror. The higher the glossiness of a printed product, the more light is reflected from its surface, and the brighter or glossier the appearance is. The glossiness of the printed medium after printing determines the beauty of the printed product. The glossiness of inkjet digital photo paper is an important prerequisite for ensuring the quality of printed products.
The glossiness of traditional inkjet digital photo paper is mainly measured by visual inspection, which is seriously affected by factors such as observation angle, light source environment and observer. Therefore, in order to overcome these influencing factors and accurately measure the glossiness of inkjet digital photo paper, a gloss meter can be used. There are many gloss meter products on the market. Here we recommend the 3nh dual-angle high-precision gloss meter YG47. The instrument has two measuring angles of 45° and 75°, and the glossiness at different angles can be measured simultaneously. The YG47 gloss meter is designed for ceramics, films, paper, plastics and other industries, and is used to measure the glossiness of mirror surfaces. The instrument has the following advantages:
1. Dual-angle design: The instrument has two measuring angles of 45° and 75°. It can measure at a single angle or at two angles at the same time, which is more applicable.
2. High measurement accuracy: The carefully adjusted measurement system and optical path layout ensure stable and accurate gloss measurement, meeting the requirements of JJG 696 working gloss meter, with superior performance, which can completely match the test data of imported gloss meters.
3. Multi-mode measurement: supports basic mode, statistical mode, continuous mode, and quality control mode switching to adapt to different application scenarios. The normal mode is for immediate measurement and fast reading; the quality control mode can customize the upper and lower limits to achieve rapid inspection of incoming materials.
4. Simple operation and easy to use: The instrument is easy to operate and can be used immediately after it is turned on. Data can be locked with one key. No complicated settings are required and the measurement can be completed in 0.5 seconds.
5. Lightweight and portable: The instrument is designed based on ergonomics, with a compact and beautiful appearance and a comfortable grip. It is not only suitable for precise measurement in the laboratory, but also convenient for flexible application in the production site.
When using the instrument to measure the glossiness of inkjet digital photo paper , make the sample as required, and then follow the operating instructions of the gloss meter to place the measuring aperture close to the sample surface to accurately measure the glossiness of the inkjet digital photo paper.
