Why not print ink light part no light we are using what method can improve the ink, ink brightness
There are roughly the following situations: 1, the ink layer thickness is not enough;2, the ink itself add brightener is not enough;3, ink imbalance (usually large water);4, the brightness of the paper itself is not enough.
Some suggestions: 1. Increase the thickness of the printing ink layer (pay attention to rub dirty, sticky back [can be properly added auxiliary solution].)2, add light oil and light syrup (also pay attention to rub dirty, sticky back);3, proper adjustment of water consumption (proper increase of wetting powder to reduce water consumption);4, full color printed version of light ink (ink transfer the harmonic, not a single light ink product);5. Replace ink or paper.
