Take strict control of the moisture content of the paper at the factory, shorten the transportation cycle as much as possible, and avoid exposure to sunlight during transportation or staying in the rainy weather for too long. These measures are the prerequisite for the printing plant to control the fineness of the product during the printing process. At the same time, it is recommended that printing manufacturers pay attention to the temperature and humidity of the warehouse and the temperature and humidity of the printing environment during storage.
1. The quality of the ink adjustment during the printing process directly affects the fineness of the flexo product
Fine prints usually need to meet the following quality requirements:
1) The ground is flat and delicate, with neat surroundings and no ghosting.
2) The network cable is partially satisfied: the network point is clear, the deformation is small, and the layer is clear.
3) If there are thin lines and small text, clear lines are required, and the text is exquisite and not confusing.
4) Multi-color overprinting requires accurate overprinting, no leakage, and no too many overlapping borders.
Then, under the premise that the printing pressure has been adjusted in place, only by adjusting the performance of the ink to maintain a stable viscosity and good printability, can the printed matter meet the above four requirements.
such as:
1) For general field products, the ink viscosity is 45 '～ 60' (coating 4 # cup), and the ink leveling and hiding power of this viscosity range are both. The ink has good hiding power and is solid on the ground; the ink has good leveling property and is fine and shiny on the ground. Otherwise, the viscosity of the ink is too large, the ink transfer ability is poor, and the solid printing is not real; the viscosity is too small, and there are water marks on the solid.
2) The viscosity of the ink used in the network cable product is 30 '～ 40' (coating 4 # cup), the ink transfer performance of this viscosity range is good, the reproduction performance of the dot is strong, and the printed product has clear dots and small deformation, which is not easy Paste edition, dirty edition.
3) For multi-color overprinted products, the trapping parameters should be designed to the minimum under the premise that the overprinting does not leak, and the printing color sequence should be arranged reasonably to ensure that the ink color of the latter color printing can cover the trapping of the previous color. live.
Second, the setting of the printing process has a crucial influence on the control of product fineness in the printing process.
Printing process settings: such as trapping parameter settings, printing color sequence arranged before and after, embossing, stamping is not set for the post-process mark, etc.
The company once had a product that was overprinted twice in dark, with many small inverse characters on it. We designed according to the normal trapping parameters, and the result was unclear and imperfect. Later, in practice, we found out the rule, set it according to the "anti-trap", and arranged the printing color sequence suitable for the trap parameters, so that the reverse white characters were printed very beautifully, and it was hardly seen that it was produced after two-color overprint. effect.
Compared with offset printing and gravure printing, the overprinting accuracy of flexographic printing machines is poor. If the products printed by the printing factory must be processed through the subsequent processes such as hot stamping and embossing, and can not be completed online with the flexo printing machine, then the simple and easy-to-read marks on the printing plate in advance are to ensure the hot stamping, The premise of accurate die cutting. This is a very small job in the printing process settings, but it is the key to ensuring whether the product packaging is beautiful after molding, and whether the product printing is suitable and perfect after packaging molding is an important aspect that reflects the fineness of the product.
In short, the improvement of the fineness of flexographic products has a direct relationship with factors such as printing equipment and plate production, as well as the overall operational human factors such as the selection of substrates, ink adjustments, printing technology and printing operation level Closer relationship. It can be said: "Who owns these software technical talents, who will control the fineness of flexo products in the printing process, who will truly have high-quality flexo quality."
Hotel chairs refer to seats used in hotel rooms, lobbies, restaurants, conference rooms, and other places. According to different functions and design styles, hotel chairs can be divided into multiple categories. Below, we will classify and introduce materials and design styles.
1. Material classification:
(1) Wooden chairs: Wooden chairs are one of the most common hotel chairs, commonly used wood including oak, beech, elm, etc. Wooden chairs have a natural and warm texture, making them suitable for use in high-end hotel rooms and lobbies.
(2) Metal chairs: Metal chairs are generally made of metal materials such as iron and aluminum, which are sturdy, durable, and stylish. They are suitable for use in hotel restaurants and meeting rooms.
(3) Plastic chairs: Plastic chairs are usually made of materials such as polypropylene, which are lightweight and easy to clean, making them suitable for use in budget hotels and outdoor spaces.
(4) Fabric chair: Fabric chairs are generally made of fabric or leather materials, with a comfortable texture, suitable for use in high-end hotel rooms and leisure areas.
2. Design style classification:
(1) Modern style: Modern style hotel chairs are designed with simple and smooth lines, emphasizing functionality and comfort. Commonly used materials include metal, plastic, and leather.
(2) Classical style: The design of hotel chairs in classical style emphasizes details and decoration, with commonly used materials such as wood and fabric, giving a sense of elegance and luxury.
Summary: Hotel chairs are classified based on material and design style, and different classifications are applicable to different places and needs. In the interior design of hotels, selecting appropriate hotel chairs can enhance guests' comfort and experience, while also coordinating with the overall design style to create a unique hotel atmosphere.
