UV cij printers often encounter the phenomenon of incomplete curing of UV ink and sticky surface during printing, and the printing effect is not ideal. The UV cij industrial inkjet printer may have the following problems: 1. UV curing light source power is not enough : That is, whether the light emitted by the UV lamp light source is consistent with the absorption spectrum of the ink. Intensity: Is the light emitted by the light source sufficient to stimulate the ink to undergo a photochemical reaction. Due to the different performance and dosage of the photosensitive agent in the ink, the main agent is light-transmissive and photosensitive Also different, so the curing strength requirements are different. Curing speed: The curing speed is too fast to complete the curing, and too slow will have an adverse effect on the ink. If the pattern is cracked, the adhesion is not good, etc., the curing speed is different due to the ink. The fast printing speed of the UV inkjet industrial inkjet printer is also the reason for the incomplete curing of the UV ink and the sticky surface. At this time, the printing speed of the UV cij industrial inkjet printer can be reduced.2. UV lamp aging As the electrode gradually decomposes when the lamp is used, the inner wall of the lamp will become black, transparency and ultraviolet light transmittance will gradually weaken, so it is necessary to check and test the UV lamp regularly. Replace and clean the lamp cover. 3. The curing speed of UV ink itself is slow. Photocuring refers to a certain photochemical reaction of the ink under the effective irradiation of ultraviolet rays, so that the ink becomes liquid and solidifies to form a pattern.
