When manufacturing various goods it is important, and often also a legal requirement, to include certain information in the packaging, labelling or directly onto the product itself. A date printer/coding machine is used to print a batch number, manufacturing date, expiry date, retail price or any other information that the manufacturer chooses.
Coding machines range in size and function and can print on a wide variety of materials and surfaces for small and large production lines.
The two basic types of coding machines are:
- Contact Coding
- Non-contact Coding.
Contact coding machines make markings through direct contact with the packaging material, which is normally in roll form before the package is formed. This packaging material can be embossed on with metal types, which are heated and transferred onto the product packaging, rubber date stamps or with thermal transfer printheads, the latest technology in printing which transfers ink onto packaging material using a thermal transfer ribbon.
Non-contact coding machines do not come into direct contact with products and can be used on the finished product, direct printing, packaging and end of line printing. They use a beam or spray ink to imprint directly onto the product. A sensor detects when a product is in range and sends a signal to the coding machine to begin printing. Types of non-contact coding machines include inkjet printers, laser printers, industrial inkjet coding machines and laser marking systems.
Coding machines range in functionality from automatic, semi-automatic and manual. This enables them to accommodate the size and speed of different production lines in the manufacturing and packaging of goods. This is something that has been taken into careful consideration at where a variety of product lines ensure that you can find a solution to any coding need. Pyrotec PackMark’s printing and coding products include Continuous Inkjet Printers, Touch Dry® Hot Melt Printers, Thermal Transfer Overprinters, Laser coders, Drop-on-demand Valve Jet Coders, Print & Apply Labellers and other labelling machinery. They also provide all of the necessary support and software to keep production running smoothly.
Pyrotec PackMark keeps up to date with advancements in coding machinery so that clients benefit from the latest technology. A great example of this is shown in Pyrotec PackMark’s relationship to a leading Johannesburg-based manufacturer of PVC refuse bags. Some of the manufacturer’s customers were disputing the number of plastic bags within the packs they purchased. The packs only contained a manually inserted date slip which was discarded when the pack was opened; making it impossible to verify or track the number of bags within the pack.
Pyrotec PackMark was able to provide a coding solution to this problem with a Markem-Imaje 9040 yellow printer, which could print directly on the manufacturers white refuse bag line, and 5 Markem-Imaje 9040 white contrast printers which could print on the black refuse bag lines. The date of manufacture, batch and machine numbers could now be included on packs; this meant they were easily traceable and so could prevent customer disputes.
