What are the storage conditions for circular colored copperplate paper?

The storage conditions for circular colored copperplate paper mainly include the following aspects:

1、 Environmental temperature and humidity

Temperature: Copperplate paper should be stored in a suitable temperature environment, avoiding excessively high or low temperatures. Generally speaking, the temperature should be controlled within the normal temperature range, avoiding prolonged exposure to high temperatures (such as exceeding 38 ℃) or low temperatures (such as below 10 ℃). Because high temperatures may cause a decrease in the mechanical properties of paper, while low temperatures may make the paper brittle and affect the printing effect.

Humidity: Humidity is a factor that needs special attention when storing copperplate paper. Copperplate paper is prone to sticking and peeling off when exposed to moisture, and cannot be stored for a long time. Therefore, it is necessary to ensure that the humidity of the storage environment is moderate and avoid moisture and mold. Usually, the relative humidity should be maintained within a certain range to avoid excessive moisture absorption or drying of the paper.

2、 Lighting conditions

Long term direct sunlight may cause discoloration and aging of copperplate paper, so direct sunlight should be avoided. When storing copperplate paper, choose a cool place or use shading materials to block sunlight.

3、 Stacking method

Neat stacking: Copperplate paper should be stacked neatly, avoiding heavy pressure and bending to prevent deformation and damage. When stacking, ensure that the paper is flat and avoid creases or indentations.

Avoid pollution: When storing copperplate paper, it should be kept away from sources of pollution such as dust, oil, etc. These pollutants may adhere to the surface of the paper, affecting the printing effect.

4、 Insect prevention measures

Insect repellents should be placed in the warehouse or room where copperplate paper is stored to prevent insect damage to the paper. At the same time, the storage environment should be regularly inspected to ensure that there are no pest infestations.

In summary, in order to ensure the quality of circular colored copperplate paper, special attention should be paid to environmental temperature and humidity, lighting conditions, stacking methods, and insect prevention measures during storage. Reasonable control of these conditions will help extend the shelf life of paper and maintain its good printing adaptability.
