Printing conditions
Plate Material
- Use PS or CTP.
- When using an on-press development plate (unprocessed plate), confirm its suitability in advance.
- Plate materials based on paper or polyester should be avoided, as it is difficult to drain water from them, triggering excessive emulsification of the ink. (If you plan to use such plates, consult with your plate manufacturer.)
- For UV offset printing, use the manufacturer's recommended product that is suitable for UV printing in terms of printing durability, etc.
Printing-Pressure Settings
Set the printing pressure as specified by the printer manufacturer. If ink transfer is unsatisfactory when following standard procedure, it may be that that the ink has over-emulsified as a result of excessive dampening water.
If the ink condition is good and ink transfer is still unsatisfactory, lower printing pressure slightly (about 10% relative to paper thickness).
