Machine vision in printing

30 minutes, 800 kg of paper, and 2000€ - that's how much on average a large printing company loses during 1 downtime. How to prevent it? By proper quality control, detecting defective raw material and reducing time, costs, and defective prints in the production process. This is a task that a vision system can handle well.

Does the printing industry need machine vision?

Working in a print house is dynamic, with strict standards, tight deadlines, and multi-step processes. Damaged paper, creases on printouts, or paper tears causing downtime are problems, which the printing team faces every day. Leaflets and drug packaging, advertisements, newspapers, notebooks, textbooks, and hundreds of other orders are being made  hundreds of prin houses in Poland every day - this is important and necessary work that vision systems can successfully support.

Error = cost. Prevent it!

A mistake in printing with consequences - in such a responsible process it is worth finding allies. What kind of allies? For example, a set of very precise cameras synchronized with the line, which observes the whole production process and controls the quality of each printed sheet. It is a system of vision quality control.

How do vision systems work in printing?

The vision system first carefully inspects every inch of the paper roll and evaluates its quality - looking for defects, cracks, holes, and wrinkles. Then it will control the process of unrolling the sheet, and in case of a paper tear, it will take a series of photos, which will give information on whether the cause of the tear was a defect in the paper or a production error. Additionally, the system will check whether the color and size of the sheets are identical to the pattern, it will observe it and in a split second, it will provide information on whether everything is correct. In postpress the vision system, depending on the order, will check several things. The watchful eye of the camera will assess the correctness of folding, creasing, foiling, die-cutting, and laminating. It will check whether everything is correctly glued, joined, or stitched, whether the bleed has been cut correctly and whether there is a legible barcode on every product. You will be informed about the progress and results of each inspection in the form of a report.

What opportunities does this open up?

Free plant resources can be reallocated to other tasks such as verifying the progress of an order, reporting possible paper complaints to the supplier, and other activities that complement the production process. The vision system will take care of quality and the plant will gain time, money, and production. This will allow you to focus on producing more efficiently.

Making money through improvement

New technology is a chance to solve the problems of print houses. The human eye is not able to work effectively at the speed of industrial printing. A vision system that ensures that the indicated quality standards are met for every product will definitely do a better job. The time and availability of the plant employees can be utilized more effectively. The plant can earn more, and the team can focus on growing the business without worrying about the quality of the orders produced.

How to implement a vision system in printing?

The easiest way to start is to contact the experts. After talking and presenting the characteristics of the plant, the specialists will identify the areas and processes where a vision system is recommended. The next step is testing, pricing, and prototyping to ensure that the solution will work efficiently and effectively for your plant. Feel free to contact the Scanway Industry team for a free consultation to discuss your company's challenges and identify areas where a vision system could support your print production.
