Discussion on the influence of environmental temperature and humidity on the flatness of cigarette mark

Cigarette label printing industry is a special packaging industry, almost all the latest ideas and the most advanced technology will be reflected in the cigarette label first. If the flatness of the cigarette label is not good, it will bring a lot of trouble to the production of cigarette labels, which will seriously affect the production schedule and the packaging of the cigarette label after it is put on the machine. Therefore, tobacco factories generally have high requirements for cigarette label printing enterprises. In order to meet the product quality requirements, the flatness of the cigarette label must be strictly controlled in the printing of the cigarette label.

The flatness of the cigarette label is closely related to the moisture content of the paper used in production. Because the paper fiber has the characteristics of water absorption, water swelling, water loss and shrinkage, when the air humidity is higher than the moisture content of the paper, the paper will absorb the water in the air to expand and elongate. Conversely, the release of water shrinks and shortens to achieve a relative balance with ambient humidity. The water absorption and loss of paper have a great relationship with the level of the ambient temperature. The higher the temperature, the faster the rate of water loss. It is because of the nature of the paper that the size changes with the change of environmental temperature and humidity. At ℃ ~ 20 ℃, the bending degree of the paper will change from 5 ° to 10 °. As the main substrate, if the paper is deformed during the printing process, it will inevitably affect the quality of the printed matter. The most representative is the unstable paper size. The shortcomings are inaccurate color registration, hot mold deviation, etc., so it is extremely important to control the temperature and humidity of the environment where each process is located and the management of the circulation program.

First, the paper printing environment should be properly controlled to prevent unevenness due to factors such as preheating, drying, and excessive moisture.

Secondly, control the temperature and humidity of each process environment to ensure that the paper matches the temperature and humidity during the handover of printing, hot stamping, die cutting, overturning and other processes. The temperature of the printing workshop should be controlled as much as possible at 18 ℃ ~ 24 ℃, and the relative humidity should be maintained In 60% ~ 65%.

In addition, there should be zero-contact management of paper between each process, and strict use of wrapping film to wrap the semi-finished paper stack to ensure the stability of its moisture content. In order to prevent the deformation of the paper caused by the long or short interval between the front and back processes, production should also be reasonably and effectively arranged to control the turnaround time of each process, and the doors and windows of the printing workshop should not be opened.

During the inspection process, if the cigarette label is found to be curled, it should be remedied in a timely manner. Humidification and dehumidification equipment should be installed in the workshop. At the same time, the temperature and humidity of the workshop should be closely monitored.

If the cigarette label is curled due to other reasons after the re-examination, the cigarette label should be placed in a certain environment for a period of time, and then packaged after the flatness is restored. Some pressurized instruments can also be used to add the cigarette label up and down Press to restore flatness.

Finally, the packaging must be strictly controlled to prevent the deformation of the cigarette label during transportation and inventory.

Flower Rack

Flower stands are designed as a kind of shelves and intended as an elegant stand for flowers grown not only indoors, but also on porches and balconies. They come in numerous designs – high or low – in a variety of styles, richly decorated or with strict minimalist lines, and they contribute to the appearance of every room. Flowers and plants make a room more inviting, comfortable and add freshness to the decor. However, when indoor plants and flowers become too many, homeowners are faced at the question how to arrange them in such a way so that to enjoy their beauty, but not overload the space? The obvious answer is to get a flower stand which will allow you to display your flowers and save valuable living space.

Flower stands can be designed either as a separate vase for home plants or as a composition which accommodates a miniature garden. Flower stand ideas differ in shapes, sizes, height, width, color and material. You can choose from classic designs, as well as unusual and original models. It may be a single stand for a pot with flowers or a stand for several pots. The advantage of a flower stand compared to any other furniture pieces is that it can help you to arrange the flower pots at different levels, combining them so that the larger flowers do not overshadow the smaller ones.

Typically flower stands are used to organize the pots in a vertical installation and the largest plants are placed on top while smaller plants are arranged at the lower levels.modern-flower-stand-design-ideas-modern-home-accessories-plant-stands-ideasDespite the fact that flower stands are not considered as the most important furniture pieces they often are an accent in the interior or exterior designs. For example, wrought iron options will perfectly complement the interior of a bedroom or living room and, at the same time, will look good as an element of the garden or patio decor. Wooden designs also perfectly fit into the interior and can be used in almost any style – from rustic, Provence, Shabby chic to modern, contemporary and minimalist.
