Oulette's modular pad printing unit aims at the combined printing track, with overprint accuracy of 0.02mm

As the Shanghai All Print Exhibition approaches in October, combined printing has become a hot topic in the industry. The linked production line of offset printing, digital and screen printing/pad printing is moving from concept to implementation, and the pad printing unit is a key module to make up for the shortcomings of printing curved and special-shaped parts, and its supporting value has attracted more attention. The modular servo pad printing unit recently disclosed by Kunshan Oulet Printing Machinery Industry Co., Ltd. is a product response to this demand.

Judging from the public technical parameters, the core design of the pad printing unit revolves around "production line embedding". The equipment adopts a sealed environmentally friendly oil cup structure and cooperates with a CCD visual automatic positioning system. The overprinting accuracy is nominally 0.02mm. This means that it can be directly installed at the back end of a digital printing press or offset printing unit to achieve the continuous operation of "digital priming + pad printing and fine color registration", eliminating the need for semi-finished product transfer and secondary loading and unloading. According to data disclosed by the manufacturer, the overall production efficiency has been improved by more than 35%, and ink loss has been reduced by about 20% compared with traditional open oil pan models.

The background to this product direction is a change in the order structure. Traditional offset printing and digital printing are difficult to directly handle the LOGO and scale printing of special-shaped workpieces such as bottle caps, plastic buttons, medical catheters, and cosmetic hoses, and the pad printing process just covers this range. Transforming pad printing from a stand-alone operation to a functional module in the production line puts forward higher requirements for equipment miniaturization, interface compatibility and positioning accuracy.

Oulette is located in Kunshan, Jiangsu Province. It was recognized as a high-tech enterprise in 2015. It specializes in intelligent pad printing machines, screen printing machines and non-standard customized equipment. Its products have passed CE certification and are exported to European, American and Southeast Asian markets. In addition to the modular pad printing unit, the company"s recent shipment records show that long rod screen printing machines and automated pad printing machines are still being delivered to domestic and foreign customers. Whether combined printing can become the next growth point of special printing equipment, the production line adaptability of the pad printing module will be one of the key variables.
