In addition to our existing range of web cleaning systems, Weducon develops custom cleaning solutions for various applications. At the request of flexo press manufacturer Celmacch, we developed a single-sided sheet cleaning system built into the press infeed. The system, based on our proven cleaning concept, improves printing results to such an extent that we now offer it as a standard feature for both flexo and digital printing.
The new cleaning system complements our established web cleaning program for dust-free production. This program delivers significant benefits, such as clean products, a safe production environment, increased productivity and significant cost savings.
Cleaning the substrate before printing
Weducon’s single-sided sheet cleaning system removes contamination from the substrate just before it is fed into the printing press. Although many manufacturers already apply web cleaning to eliminate contamination during manufacturing, several processes follow after production. Think of stacking and transport. These processes again generate dust and fibers which build up on the substrate.
When these particles enter the printing press during sheet transport, they contaminate the first printing unit quickly. For printers, this causes problems such as contaminated ink, imperfections in the printed image (donuts, hickeys, bullseyes). Ultimately, this results in production loss or complaints. A simple and sufficient way to avoid these problems is to clean the substrate before it enters the printing press.
Because single-sided printing uses a vacuum system to transport the substrate, only cleaning the printable side of the substrate is possible at this stage. Therefore, we implement our single-sided sheet cleaning system before the first printing unit. Here it performs a final cleaning – contactless and without slowing the feeding process.
Like our web cleaning systems, our single-sided sheet cleaning system typically requires minimal modifications to existing equipment. By preparing the installation process to the last detail, your new cleaning system can run within most routine maintenance stops.
