High-resolution inkjet printer: At present, there are two main technologies for high-resolution inkjet printers on the market. One is that Searle's nozzle adopts piezoelectric technology, and the other is HP's thermal foaming technology. Both of them use high-resolution inkjet printer to print electronic supervision codes online with clear and variable information, which can be used for printing paper materials or secondary packaging boxes in pharmaceutical enterprises or printing enterprises. Its characteristics are flexible coding and low initial investment. It is more suitable for enterprises with few types and quantities of products and manual packaging lines.
Thermal transfer: Intelligent thermal transfer coding is mainly used for coding film packaging products. Thermal transfer equipment is installed in the peritoneum, bag making, rewinding, cutting and setting after printing in the printing factory to realize product packaging coding. Adding thermal transfer equipment to the automatic packaging (filling) equipment of production enterprises can realize the coding of product packaging. It is characterized by high quality and clarity of spray-printed bar code, which can be matched with existing packaging machinery for coding. Suitable for a small number of products.
Labeling and coding: for the enterprise itself, the number of products is small and there are many kinds. It can be considered that the printing factory can provide coding labels, and the product coding can be realized by manual or labeling machine, which is suitable for all kinds of packaging materials. On the semi-automatic or full-automatic production line, a printing and labeling machine can also be set on the secondary packaging to realize online labeling and coding. Its characteristic is that it can be applied to products of any material, regardless of ink adsorption. Bar code printing is neat and easy to reach grade C or above; You can make personalized labels according to your own preferences.
Laser marking and coding: laser engraving and coding is suitable for all kinds of materials, whether it is the first-class coding or the second-class coding in pharmaceutical factories, it can be printed online at high speed, and the laser logo is a permanent logo, which is better than the traditional one. Its characteristics are high precision, high efficiency, unchangeable laser marking, environmental protection, no pollution and no consumables, but the initial investment cost is relatively high.
Bar code printing and coding: the electronic supervision code is printed by a bar code printer and pasted on the primary packaging and secondary packaging. Three-level packaging is suitable for all kinds of materials and production lines. However, in pharmaceutical enterprises with a large variety and quantity of production, it takes time to assign codes to the first-class packaging by bar code printing, while it takes time to assign codes to the second-class and third-class packaging by bar code printing.
Variable printing code: In the pharmaceutical packaging and printing factory, the variable coding printing technology is adopted to print the variable drug supervision code at a fixed position, which is suitable for large-scale and various types of pharmaceutical enterprises. At present, there are three main types of variable printing technology, namely oily inkjet equipment, water-based inkjet equipment and UV inkjet equipment, and each has its own advantages and disadvantages. Oily ink jet is mainly used to spray codes on materials such as bill printing and carbonless copy paper. Oily ink belongs to quick-drying ink, which is waterproof and sun-proof; Water-based inkjet has flexible configuration, wide application and fast printing speed, and is mainly used for permeable materials such as paper. UV ink can spray a variety of materials. After UV curing, the bar code is firmly attached, waterproof and scratch-proof, and the bar code level is more guaranteed. Using this method to assign codes to a large number of essential drugs and various pharmaceutical enterprises can save costs.
