Q1:How to avoid color difference?
A: Use new ink each time. Avoiding water adding, if it is needful, try to add little each time and mix evenly. Use the same substrate each time(the base color of the substrate will cause color difference. Maintain the printing press, anilox roller, andscraper in time; clean the ink box in time.Q2: Why there is odor from the ink?
A: Tap water will shorten the ink shelf time. It will deteriorate easier if too much tap water added. Stock the ink in sealed condition and in ventilated place.Q3: How to solve the edge fluffing problem?
A: In low printing speed, restart the press or tune the press until the scraping plate appears. In normal high speed printing, add slowing dry agent or stabilizer to solve the fluffing problem.Q4: What are the reasons for the printed words are too slim and not clear?
A: The printing is too slow but drying is fast, poor converting. Printing pressure is too big and the ink loading is too much.Q5: The printing drying condition is not good, what are the reasons?
A: The ambient temperature is too low; the humidity is too high;the power of the drying tunnel or infrared lamp is low. Substrate surface is too smooth, and the ink absorption deviate.Q6: The ink become thick after long storage, how can I reuse it?
A: Generally speaking, if stored in our suggested way, the ink will keep in good condition. It become thick because it is stored unsealed and the water volatilized. you can add some stabilizer and water, stir evenly and filter. Then you can use again.
