First, increasing the equipment's boot rate is the key to boosting efficiency.
Reducing the time needed for changing printing orders is one of the most effective ways to improve the productivity of a printing press. For example, if each machine handles 20 orders per day and each order change takes 20 minutes, that’s 400 minutes lost in downtime every day. However, if we can cut that down to just 10 minutes per order change, we save 200 minutes daily, which translates into a 50% increase in overall efficiency. To achieve this, we need to plan and organize all pre-printing tasks, on-site setup, and team assignments effectively. Only by maximizing the equipment's uptime can we truly reach that 50% efficiency gain. But how exactly do we do it?Second, focus on efficient pre-press preparation with minimal effort.
Let’s dive into the details of what needs to be done during pre-press preparation. What should we prepare before starting the print job? How can we ensure everything is ready on time? 1. Prepare the ink required for the printing press Before starting, receive the ink and check its pH level, viscosity, and color accuracy. The pH level affects how the ink adheres to the paper, especially in multi-color printing. If the pH isn’t properly adjusted—like setting red ink at pH 9 and then blue ink at pH 8—it can lead to poor overprint results. Viscosity is also critical; if it’s too high, the ink may not transfer well, leading to smudging or poor clarity. Color checks are equally important—if the ink is off, cleaning it could waste 2 kg of ink and take 15 minutes. After verifying the production schedule, assign someone to pick up the correct ink for the day and bring it to the workshop. Stir the ink thoroughly before placing it on the machine and recycle any leftover ink. 2. Prepare the printing plates A common issue is when a plate is incorrect or worn out, causing the press to stop. This leads to 30 minutes of downtime and 2–4 kg of ink wasted. To avoid this: - The printing room staff should retrieve the plates based on the production schedule. - The person collecting the plates should first check for errors, such as incorrect text or damage. - Then, verify the plate number and send it to the machine. 3. Prepare the cardboard Sometimes, after the plates and inks are set up, the cardboard isn’t ready, forcing an ink wash and order change. To prevent this: - Check whether the cardboard has already been produced. - Sort the cardboard according to the production schedule. Summary: By focusing on these three areas, on-site downtime can be reduced by 20%. It’s through careful attention to detail that we gradually boost the efficiency of the printing press.3. Manage internal and external tasks simultaneously to increase printing press efficiency by 50%
To improve printing efficiency, experts recommend recording your current workflow and categorizing tasks into internal and external ones. Convert as many internal tasks as possible into external ones, and reduce the time spent on external tasks. 1. Internal Tasks Internal tasks require the machine to be stopped, like changing plates or adjusting the impression cylinder. To complete them faster: - Assign roles clearly: one person as the leader, others as assistants. - Reduce idle time after an order ends by preparing ahead. - Avoid repeated tool searches once the machine starts. - Pre-check the next order’s settings and materials to save time. - Encourage teamwork so that if one person is delayed, others step in to help. Summary: Following these steps can save 4–5 minutes per order, meaning 100 minutes saved per day for 20 orders, resulting in a 20% efficiency gain. 2. External Tasks External tasks can be done while the machine is running, such as preparing plates, inks, or adjusting the stacker. To speed this up: - Clean the feed area quickly and start adjustments. - Assign specific people to handle external tasks efficiently. Summary: To achieve a 50% improvement, real-time on-site verification is essential. Using a camera to record the process and discussing improvements can lead to significant time savings after a few iterations.25Mm Lashes,3D Mink Eyelashes,Thick Fluffy Mink Lashes,Natural Long Mink Lashes
