Among various types of flexographic printing machines, the CI (Central Impression) type stands out for its large size, high cost, and unmatched color precision. It is the ideal choice for high-end, full-color printing, such as paper cups.
A key challenge in flexographic printing is ink smudging, especially when ink transfers to the inner surface of cups due to incomplete drying. This typically results from slow printing speeds or limited drying zones.
The CI type solves this with ample drying capacity and a robust machine design, preventing ink transfer issues. Unlike line or stack types, it features a central impression cylinder that maintains strong web tension and stable substrate control, ensuring perfect color registration, even in complex multi-color jobs.
