Four major problems in the development of UV printing inks

BAIDU_CLB_fillSlot("858283");
UV ink is an environmentally friendly ink developed in recent years. In the context of industry printing vigorously promoting green printing , it is increasingly valued by printing companies. Although UV inks have many advantages, their popularity and application must also solve and improve the following problems.

1. High cost of use

On the one hand, UV inks are currently on a smaller market and have higher research costs, which makes the price of UV inks higher than conventional inks. On the other hand, UV inks must use special UV blankets, UV ink rollers and cleaning agents, which greatly increases their application cost. At the same time, UV curing equipment associated with UV inks is expensive. These make the use of UV inks very expensive.

2. Adhesion needs to be improved

During the curing process of the UV ink, the internal components are cross-linked and polymerized, and the volume changes instantaneously, resulting in a large internal stress. At this time, it is difficult for the UV light to penetrate the thick coating containing the pigment, which is likely to cause the UV ink to be incompletely cured. Poor adhesion. Although this problem can be improved by treating the surface of the substrate, the most fundamental solution is to develop a UV ink that has good adsorptivity, low shrinkage stress, and low cost.

3. Must develop suitable dampening solution

UV inks are essentially different from traditional inks, which can be used for non-absorbent substrates, and UV inks have different formulations depending on the substrate. Therefore, in offset printing , the required dampening solution has a certain adaptability and is matched with the UV ink to ensure the required printing quality.

4. Short shelf life

At present, UV inks have a short shelf life, mostly for about half a year. This is mainly because UV inks are easily gelatinized and deteriorated.

With the deepening of the green printing strategy, people's environmental protection requirements for inks and other consumables will gradually increase. UV inks will surely receive people's attention because of their environmental characteristics. Although they still have some problems to be solved, they still have some problems to be solved. It is gradually maturing, and we are expecting it to shine.

Corner Desk

Corner desk is a type of desk specifically designed to fit into the corner of a room. It is a space-efficient solution that maximizes the use of corner areas, making it a popular choice for home offices, bedrooms, or any room where space is limited. Here are some key features and aspects of a corner desk:

  1. Shape and Configuration: Corner desks are typically L-shaped or sometimes even U-shaped, with one side of the desk extending along each wall of the corner. The L-shape provides ample workspace, allowing you to have separate areas for different tasks, such as computer work, writing, or organizing.

  2. Space-Efficient Design: The primary advantage of a corner desk is its space-efficient design. By utilizing the corner of a room, it makes the most of the available space and provides a large work surface while minimizing the footprint of the desk. This is particularly beneficial in smaller rooms or home offices.

  3. Work Surface: Corner desks offer a generous amount of work surface area. The size and dimensions of the desk can vary, so you can choose one that suits your specific needs and available space. The work surface can accommodate a computer, monitor, keyboard, and other work essentials, providing ample room to spread out and work comfortably.

  4. Storage Options: Many corner desks come with built-in storage features to help keep your workspace organized. These can include drawers, shelves, or cabinets for storing office supplies, files, books, or other items. Consider your storage needs and the available storage options when selecting a corner desk.

  5. Versatility: Corner desks are versatile and can be used in various settings. They are commonly used as home office desks but can also be placed in bedrooms, living rooms, or any room where a workspace is desired. They can be used as a dedicated workstation or as a multifunctional surface for various tasks.

  6. Ergonomics: Consider the ergonomic design of the corner desk, such as the height of the work surface and the placement of keyboard trays, to ensure a comfortable and productive workspace. Adjustability features, such as height-adjustable desks, can further enhance ergonomic support.

  7. Style and Material: Corner desks are available in a wide range of styles, designs, and materials. You can choose from various finishes, such as wood, metal, glass, or a combination, to match your existing decor and personal style preferences.
