There are usually two reasons for the large graininess of white ink printed by UV flatbed printers: the quality problem of the white UV ink itself and the problem of the ICC curve. The solution is as follows:
1.Compared with other pigmented inks, the white UV ink itself has larger precipitation and ink impurities due to the addition of titanium dioxide. If the quality of the ink used is poor, on the one hand, it will accelerate the clogging process of the print head and shorten its service life. On the other hand, there will be large graininess and ink breakage during the printing process. This requires contacting the manufacturer to replace higher quality UV ink. TODOjet uses high-quality UV ink, so there is no need to worry about print quality and ink breakage.
2.ICC curve files When the white ink has a large graininess, it is generally because the ICC curve does not match. You can contact the manufacturer to send a matching ICC curve file, and this problem can be solved after replacement.
It should be noted that if the UV flatbed printer has ink stirring function, you can turn on the stirring for 5 minutes before printing. If there is no stirring function, it needs to be stirred manually.
TODOjet UV flatbed printers are equipped with ICC curve files that match the ink, and have a white ink circulation function, which is convenient to operate. Welcome to consult!
