Adhesion Properties of Innova 73 H
For printing cylinders with repeat lengths below 600mm, INNOVA 73H is the right choice because it will hold the plates down and enables easy plate and tape removal at the same time. Especially if you are using a thick printing plate-like 1.7mm. That means for thinner plates and larger sleeves, the INNOVA 73 version is safer to use.
Printing Properties of Innova 73 H
The choice of the appropriate hardness depends primarily on the ink coverage of the printing plate. Fine lines and ink coverage up to 20% require a soft Plate Mounting Tape like Innova 69H. But solid areas with 100% ink coverage require a hard tape like Innova 73H. It gives it a perfect print performance above 80% ink coverage. But if you are uncertain, it can be helpful to also to try one level softer with our Innova 72H. In fact, the majority of press runs get ideal results with one of the three medium adhesive tapes. That is why most customers use Innova 70H-72H. However, it is recommend taking a look at the printing plate type. Hard printing plates may require softer tape. Other factors are the substrate and ink viscosity. On uncoated paper, soft tapes will provide the best results. But with PE-film, it is safer to go with medium hardness. Because Flexo Printing has few standards, we recommend a fingerprint test. The fingerprint test is the most scientific way to get to the right combination.
