Step#1 Prepress Preparation
Before any printing begins, prepress preparation is crucial for ensuring a smooth and efficient process. This involves tasks like creating the design layout, selecting the appropriate inks, and preparing the printing plates. Attention to detail in this phase can significantly impact final print quality and overall project success. Proper prepress preparation also minimizes the risk of costly errors during the printing stage.
Step#2 Plate Mounting
The next step involves mounting the printing plates onto the printing cylinder. This is a critical step, as improper mounting can lead to misalignment issues, affecting the final print quality. The plates must be securely attached and properly aligned to ensure that the print comes out as intended. Advanced narrow web flexo printing machines often come with automated plate mounting systems to reduce human error.
Step#3 Ink Mixing and Application
Consistency in ink formulation is vital for achieving uniform color throughout the print run. The ink is then applied to the printing plates through an anilox roll, which ensures a precise and even distribution of ink. Otpack offers machines with advanced ink mixing systems that provide consistent color matching and reduce ink wastage.
Step#4 Printing and In-Line Finishing
The actual printing process involves running the substrate through the machine, where the inked plates make contact and transfer the design. In-line finishing options like die-cutting, laminating, or varnishing can also be performed simultaneously. High-quality machines ensure that the printing and finishing are completed in a single pass, reducing the need for additional steps.
Step#5 Quality Control and Inspection
After the printing and in-line finishing is complete, the final step involves quality control and inspection. Each print is examined for any defects or inconsistencies, and corrective measures are taken if necessary. This step is crucial for maintaining brand integrity and customer satisfaction. Automated inspection systems are increasingly being integrated into modern narrow web flexo printing machines to expedite this process.
