One of the characteristics of HP Indigo digital inks in practice is that the light transmittance is so good that traditional gravure printing can’t achieve its cool translucency. On this issue, I am in the "HP Indigo Industrial Machine House" technical exchange group. There are open-ended questions and discussions. I believe this issue may also be of concern to you, so I hereby share it.
The translucent color performance of Indigo digital ink:
Through the above case, you can clearly see that the light transmittance of the digital ink is very good, especially after the yellow ink in the "Golden Celery" case on the right is transparent, the metallic gold texture presented against the aluminum film is particularly cool! ! Now we use traditional gravure ink for printing. After compounding the aluminum film, we find that the light transmittance of the traditional ink is much worse than that of the digital ink, and the metallic luster of the aluminum film is covered!
After discussion, the first thing that was determined is that Indigo digital ink is nanometer ink, fine and thin! ! Very good light transmission! ! The traditional ink is relatively thick and thick, and has strong shading properties. The gold and silver inks in the traditional ink have the strongest covering power. If you want to obtain a good light transmission and display gold effect, the ink must not contain gold or silver ink. ! ! The digital printing of film is a new issue. If you have any questions, you can exchange and discuss more. At the same time, I hope that more gravure printing factories can provide customers with diversified small batch and sample bag proofing services through the digital printing film we provide and their own back-end production capacity. , The industrialization process of thin-film digital printing will be even more exciting with your participation!
