How to achieve the best results in offset coating with our effect pigments
Effect pigments in offset coating allow creative designs on various materials. For trouble-free printing and strong effects, it is important to select the correct anilox rollers and photopolymer plates. We have experienced excellent pigment transfer and coverage with the following photopolymer plates:
• Nylocoat® Gold A 116 and Seal F 116 by the Flint Group
• Cyrel® DVS by DuPont
The cell geometry of the anilox rollers and the effect pigments should be matched according to the table below.
Offset coating guidelines
| Pigment particle size | Theoretical dispensing volume (cm^3/m^2) | Screen angle hexagonal | Lines/cm | Lines/inch |
|---|---|---|---|---|
< 15 μm 5 – 25 μm |
10 – 13 | 60° or hachure | 80 – 120 | 200 – 300 |
| 10 – 60 μm | 12 – 20 | 60° or hachure | 60 – 80 | 150 – 200 |
10 – 100 μm 10 – 125 μm |
20 – 25 | 60° or hachure | 40 – 50 | 100 – 130 |
| 20 – 200 μm | 24 – 30 | 60° | 30 – 34 | 75 – 85 |
Stop crushed edges
To avoid crushed edges, we recommend adding base leaders to the polymer plates. For double coating applications, ensure that the base leaders for the two coating units are next to each other.
