Major printing ink failures and solutions

The "Tianhe" brand ink produced by our company adopts synthetic resin and alkyd resin as the main raw materials, and has the characteristics of fast drying, large gloss, good fluidity, strong water resistance, good transfer and transferability, and clear outlets. Since it was put on the market, it has always been favored by users. In order to serve the users better, we now have a series of major failures, causes, and remedies that have appeared in the printing, for reference by customers.
First, flying ink Ink is the ink from the ink roller between the fog and scattered dispersed in the printing room for a long time does not fall.
Analysis: Cause 1. The ink viscosity is too large, resulting in long wire drawing. Solution: Add a part of the spreader to reduce the viscosity, but avoid too much, otherwise it will affect the drying speed.
Cause 2. Ink storage Electrostatic charges are attracted to the opposite charge in the air. Solution: Install a static eliminator on the press.
Cause 3. The printer has poor accuracy and excessive vibration. Solution: Correct ink roller roundness and uneven pressure.
Cause 4. Seasonal replacement temperature suddenly changed. Solution: Adjust the shop temperature and temperature.
Cause 5. The ink viscosity is too small. The solution reduces the fluidity and controls the amount of ink.
Second, plug version phenomenon: ink mixed with paper powder was like ink residue attached to the printing plate and the surface of the printed product.
Analysis of the reasons 1. Ink viscosity is too large or too small. Solution: Adjust the viscosity of the ink and the appropriate degree to reduce the amount of ink used.
Cause 2. The surface strength of the paper is poor, and the paper powder easily falls off. Solution: Replace the paper with good surface strength.
In addition, the clog on the plate should be cleaned frequently.
Third, rub the dirty phenomenon: printed materials are easy to wipe off by hand.
Cause: The surface of the paper is too smooth and the paper is hard and dense, and is not suitable for penetrating ink. Solution: Increase the printing pressure, reduce the speed of the machine, and use ink with high viscosity and high color concentration.
Fourth, the phenomenon of text blur: The printed text strokes are thick and fuzzy.
Analyze the cause 1. The ink supply is too large. Solution: Reduce the ink supply.
Cause 2. Printing pressure is high. Solution: Reduce the pressure.
Cause 3. Paper is thin and poor in strength. Solution: Replace the paper.
In summary, some of the major problems in the use of ink for the user's reference, in general, the printing problem is summarized in three reasons: First, the ink problem. The second is the status of printing presses and printing objects. The third is the printer's skills. These three reasons may be the main factors causing the failure in printing. When the problem arises, the user will carry out a detailed analysis of the three to clarify the cause of the failure so as to take corresponding countermeasures.
