Color printing carton products appear ink drying speed is slow, it is easy to cause printing is sticky, and bring some difficulties to post-processing, this problem we think can be solved from the following three aspects: 1, appropriate extension of the post-processing interval or the printed goods spread out to dry. 2, use ink absorption performance slightly stronger base paper: such as coated white board in this respect is better than bleaching hanging paper white board absorption performance. 3, choose fast drying ink or according to the characteristics of the ink to add the appropriate amount of drying additives, and reduce the amount of ink. Second, the ink part of the product be broken stick or stick, the emergence of the problem because the material of white board paper, coated paper, gelatine printing paper, paper structure and the production process is different, especially in winter, due to the temperature low ink viscosity, white board paper liners or coating layer often arise ink parts be sticky hairs or stick broken phenomenon, seriously affect the appearance of the print quality. In view of this problem, our Guangzhou Baiyun carton factory gives the solution as follows: 1, choose the white board with strong wool, and the printing pressure should not be too big. 2, the rubber blanket under the pad of the lining paper can not be more, the pad can not be soft, the rubber blanket used for a period of time after the application of cleaning agent scrub clean. 3, you can add wetting powder and alcohol in fountain solution (the proportion is 5% ~ 20%) to reduce the tension on the edge of the inking part, or according to different types of ink, choose the corresponding ink oil, destick or diluent to reduce the viscosity of the ink. 4, the printing workshop and room temperature control, generally controlled in 19℃ ~ 28℃ is appropriate, into the winter is best to properly heat the ink, which is conducive to improve the fluidity of ink, and reduce the viscosity of ink.
