No one does paper bag printing better than the packaging industry, and specializing in quality control means industry-related printing defects are also more than average and impact the end user customer experience and void the supplier control efforts to build their brand through proper visibility and product image. Printing in a wide range of paper thickness adds to the complexities of this problem. Not enough printing pressure and the image is ambiguous, too much printing pressure and damage is caused to the substrate. Quality control can help impact the end-user customer experience and help the supplier control their brand image. With over 20 years in the industry, Qiangtuo is focused on crafting their solutions to this problem of printing quality pressures and their reputation for R&D, Design, Production and Maintenance Service are Industry Awards winning, making them the equipment of choice for thousands of companies globally.
Handling Different Paper Weights
To achieve this, Qiangtuo's paper bag printing machine utilizes an automatic constant tension control system. The system automatically adjusts its tension based on the paper's thickness. For instance, when printing on 30gsm paper, the system reduces its tension to avoid tearing. In contrast, when printing on 80gsm paper, the system increases its tension to ensure the paper stays flat. Control And Accuracy Of Printing The Machine Control System's Optimal Accuracy Super
The Super Precise Servo Control System is the second technology employed by the machine. The system controls the printing drum's pressure and speed, which is up to 80m/min, and therefore regulates the printing pressure to ensure that every register of each color is aligned with an accuracy of 0.2mm regardless of the thickness of the paper. Continuous Monitoring Of Paper The Third Technology Of The Double Photoelectric S
The third to none double photoelectric sensor deviation correction system continuously adjusts the positional deviation of the paper during the machine's operation, therefore exceeding the required standard of uneven thickness of the paper on which offset printing. The performance of these systems ensures consistent printing.
Qiangtuo's paper bag printing machine has a uniquely flexible design to accommodate different paper thicknesses. The machine's printing plate cylinder is capable of raising and lowering itself automatically. When changing from thin to thick paper, the cylinder raises to increase pressure, and when changing to thinner paper, the cylinder lowers to reduce pressure, the ink is then automatically stirred to prevent ink from settling when not in use. Also, the material loading and unloading use a pneumatic lifting structure. This structure optimally positions the paper roll vertically by its thickness and weight to ensure smooth paper feeding without damaging the paper. The machines touchscreen interface allows the user to preset the parameters (pressure and speed) to fit a required paper thickness at the push of a button, and the working status is realtime displayed to allow the user to react quickly, thereby greatly improving operational efficiency and quality stability.
A lot of consumers use Qiangtuo’s paper printing machine and thank Qiangtuo about their food packaging for its machine that does 35gsm bread bag printing and 70gsm shopping bag printing. A packaging company in Guangzhou had issues with their bread bag printing and shopping bag printing because they would get blurred patterns and their paper would be thin. Qiangtuo’s machine does automatic printing with paper bag printing and made their company have 99% printing for their products. Another example is with a gift bag company in Zhejiang. They print with a Qiangtuo machine thin 40gsm gift bags and thick 65gsm gift bags. Because of the consistency in coloring customers appreciate the printing and valued the company for their success in avoiding returns with color issues. These customers strongly appreciated their machines.
Qiangtuo has strict quality contro,, with the hope that all their machines provide the same level of performance and stability. Indeed, stability begins with construction. Qiangtuo only purchases quality components, and each machine is run factory tested for 24 hours with varying thicknesses of paper, ensuring that all machines pass quality control. Qiangtuo’s customer support has a year warranty and lifetime maintenance. Technical assistance is provided remotely and if necessary, components are shipped. A customer from Southeast Asia had issues with printing 50gsm paper, and in 2 hours Qiangtuo's engineers adjusted machine parameters remotely to get the customer in production. This guarantees that all machines in the field will continue to provide the same support and functionality.
To sum it up, Qiangtuo's paper bag printing machine offers the most advanced technology, integrated seamlessly, thoughtfully, and human-centered, along with quality assurance and a good attention to after-sales service with respect to constant printing quality irrespective of the type of paper thickness.The machines’ constant tension control, absolute servo system, and deviation correction system address the most pertinent challenges of printing on various thicknesses of paper, as evidenced by diverse clients across multiple sectors and validated by Qiangtuo’s two decades of service. For companies tasked with printing on paper bags of varying thicknesses in the market, Qiangtuo’s paper bag printing machine is the best option as it offers superior productivity. Moreover, Qiangtuo enhances the quality and brand value of their product.
