Direct Printing for Streamlined Package Production

A system and method for accurate positioning of dynamic prints on packaging materials like food containers to ensure correct scanning and readability of the prints. The system involves a separate printing station downstream of the decoration printing equipment. The position of each print is adjusted based on comparing the actual distance between the print and a reference position on the material to the desired distance. This compensates for variations in material dimensions and snaking due to factors like moisture content.

Printing technique for packaging materials like candy bags that avoids visible ink lines on the final pouch after bag making. The technique involves printing on the packaging base material, then determining the hidden areas that will be inside the final pouch after bag making. Ink is then flushed into those hidden areas during printing to prevent visible lines when the bags are formed. The technique involves obtaining position information of the hidden regions using a device, and flushing ink into those areas during printing using the nozzle.

Packaging apparatus that reduces waste of packaging material by printing packaging instructions in a specific sequence. The apparatus has a printing section that prints on the packaging material as it moves. It can print at two positions - an initial position downstream of the normal position. The initial position is closer to the packaging formation area. After printing at the initial position, the material is transported a shorter distance than the normal packaging width. Then it alternates between printing at the normal position and transporting the full packaging width. This prevents unnecessary waste by only printing closer to the packaging area for the first bag, then moving to the normal position for subsequent bags.

Digitally printing graphics and text on flexible and semi-rigid packaging materials like bags and pouches. The method involves using a separate digital printing system to pre-print the bags before converting them into finished products, or post-printing on already-made bags. The digital printing system deposits ink or toner onto the bag surface to form an image. The ink adheres using fuser fluid, heat, or UV curing. This allows customized printing on bags without requiring offset printing. The pre-printing allows consistent placement of images across bags. The post-printing allows adding customized graphics to existing bags.

Inkjet printing system for customizing and printing images on corrugated cardboard packaging without the need for multiple fixed print heads. The system uses movable print heads that can be easily accessed and replaced. The heads are mounted on a carriage that moves laterally over the cardboard. Ink supply is provided through flexible tubes connected to the heads. This eliminates the need for fixed heads and manual connections. The movable heads prevent ink flow issues and provide better coverage over the cardboard width. The accessible tube connections simplify maintenance. The heads are also protected from impacts since they are not cantilevered.

A multifunctional combination packaging printing machine that allows printing multiple processes on the same product without quality degradation. The machine has separate printing units for processes like offset, flexo, gravure, and foil stamping. The substrate unwinds, prints, and rewinds in a continuous loop between the units without intermediate transports. This avoids issues like ghosting, trailing, and mildew that can occur when moving printed material between machines.

Printing packaging material edges to improve aesthetics and prevent falling flaps. The method involves automatically printing the edges of packed products like cosmetics using a dedicated printing device. The device applies ink to the edges of the packaging material as it is wrapped around the product. This eliminates the need for separate colored paper or additional lamination steps to match the printed top surface. The edges are coated evenly using a rotating support plate and printing apparatus. This allows consistent edge printing without overlap issues.

A method for high-quality inkjet printing on flexible packaging materials without impairing flexibility. The method involves applying a thin inkjet receiving layer onto the flexible packaging material. An inkjet printer then prints onto the receiving layer to form the printed image. An adhesive layer and sealant film are added to complete the flexible packaging laminate. The receiving layer thickness is 2-20 μm. This allows the inkjet ink to be retained and prevent bleeding, while still allowing flexibility. The inkjet receiving layer improves print quality on the flexible packaging material without impairing its flexibility.

Inkjet printing system for high-speed packaging labeling that uses UV LEDs to cure the ink quickly and eliminate drying time. The system involves an inkjet printer with an UV LED curing device. The inkjet printer prints the packaging labels using UV curable ink. The UV LEDs irradiate the printed labels to cure the ink rapidly, enabling fast drying without needing heat or solvents. The UV LEDs can be moved with the labels or selectively activated to cure only the printed areas. This allows high-speed label printing without drying limitations.

On-line packaging printing system for cigarette packs that allows high speed printing without stopping the production line when print quality issues occur. The system uses multiple print heads, like inkjet heads, that can all print the packs individually at full speed. If one print head has quality issues, the others can take over printing. This provides redundancy to maintain production while the defective head is cleaned or replaced.

Flexible inkjet printer that can print on a variety of transparent and opaque packaging materials by allowing front or back printing. The printer has multiple ink heads, including a white head and process color heads, mounted on a carriage. It uses a control mechanism to selectively print white ink before or after process colors. This allows front printing with white background on transparent media or back printing with white background on opaque media. The white head positioning and carriage movement are optimized for consistent print quality.

Printing absorbent product packaging bags using inkjet printing to provide customized designs and patterns on each bag. This allows changing the printed patterns on continuously produced bags without stopping the production line. Inkjet printing is applied to a predetermined position of the packaging material during bagging or post-packaging. This enables customizing the printed designs for each bag without needing multiple roll changes.

Printing digital images directly onto packaging materials like cartons, bottles, and laminated packaging using inkjet printers, eliminating the need for plates, cylinders, and screens in conventional printing processes. The method involves generating a digital image electronically, transferring it to a printing site, and digitally printing it directly onto the packaging material at the site. This reduces the time and waste compared to traditional printing methods like offset and gravure.
