Influence of environment on gravure ink.

      The printing adaptability of ink is related to ambient temperature and humidity. The selection of ink should consider the climate difference, and give priority to the ink of enterprises in nearby areas.There Are Two Factors Affecting Printing Quality: Environment And Climate

      The technical conditions of gravure printing include printing speed (linear speed), drying capacity, plate roller performance, gravure printing mode (table printing, back printing), printing color number, printing sequence, ambient temperature, humidity, etc. There Are Two Factors Affecting Printing Quality: Environment And Climate

      The technical conditions of gravure printing directly affect the ink transfer rate and drying speed, so the ink must be selected reasonably and economically according to the technical conditions.There Are Two Factors Affecting Printing Quality: Environment And Climate

       For example, when the humidity on the production site is high and the printing speed is high, select high-grade ink with high transfer rate and fast drying speed to prevent adhesion after film printing. Under the process conditions of air drying and fast printing speed, select the ink with high viscosity and anti-static agent to avoid the quality problems caused by static electricity.There Are Two Factors Affecting Printing Quality: Environment And Climate

The influence of environment on pad printing ink.

      Generally, ink manufacturers will give guidance on what kind of printing ink is suitable for, but this opinion is for reference only. To select the appropriate ink, you need to understand what kind of printed matter is used, the printed matter needs pretreatment before printing,.There Are Two Factors Affecting Printing Quality: Environment And Climate.

       what color of ink needs to be printed, the recommended drying or curing method, and various performance requirements such as wear resistance, chemical resistance and climate resistance of the ink.There Are Two Factors Affecting Printing Quality: Environment And Climate

      In the process of controlling ink performance, ambient temperature and relative humidity have a great impact on ink performance. The higher the temperature is, the faster the solvent volatilizes and the more viscous the ink is. However, the two extremes of relative humidity (very high humidity and very low humidity) are not so.There Are Two Factors Affecting Printing Quality: Environment And Climate

      When the relative humidity is at two extremes, it is difficult for the printer to control the ink performance, which has always been a problem perplexing the printer. Humidity above 80 ~ 85% will slow down the speed of ink viscosity, and humidity below 15 ~ 20% will also slow down the speed of ink viscosity. There Are Two Factors Affecting Printing Quality: Environment And Climate

      However, when the environment is at two extremes, simply controlling the characteristics of ink solvent can hardly improve the viscosity of ink.There Are Two Factors Affecting Printing Quality: Environment And Climate
