Máquina de marcação a laser versus impressora jato de tinta: qual é a melhor para o seu negócio?

Laser marking machine vs inkjet printer: which is best for your business?

With the continuous development of science and technology, there has been a change in the laser electromechanical industry, from the first inkjet printers to today's laser marking machines, each with its own merits.

However, if we predict the winner in a contest between laser marking machines and inkjet printers, the trend is clear: laser marking machines are replacing inkjet printers.

Laser marking machines engrave a permanent mark that cannot be erased. This is achieved by directly vaporizing the surface of the object with a laser, creating an instantly visible mark that requires no auxiliary tools for recognition, making it easier for consumers to identify. Furthermore, laser marking machines do not require consumable materials, simplifying maintenance.

Breaking away from the norms and monotony of traditional inkjet technology, laser marking machines introduce a completely new coding method. This highlights the uniqueness of the product and the distinction of the brand, increasing competitiveness in an increasingly fierce market.

Furthermore, it provides a powerful tool to reduce product upgrade cycles and facilitate flexible production.

The function of laser marking machines to code randomly or for anti-counterfeiting purposes allows each wine bottle or small bottle cap to have a unique code, allowing direct, quick and convenient identification.

Furthermore, they can spread information such as prices and promotions on wine packaging, effectively controlling the sales price and avoiding market fluctuations.

An inkjet printer is a non-contact inkjet marking system controlled by a microcontroller.

It applies pressure to the ink inside the system by controlling the internal gear pump or by supplying compressed gas from outside the machine, causing the ink to be ejected from a nozzle with a hole diameter of several tens of micrometers.

The continuous line of emitted ink is divided into droplets of equal size and frequency at equal intervals by the crystal oscillating signal added above the nozzle.

The droplets are then charged individually as they pass the charging electrode, with the amount of charge controlled by the central processing unit (CPU).

After passing through the sensing electrode to check the charge and phase accuracy of each droplet, the charged droplets deflect in the deflection field formed by the deflection electrode, shooting from the nozzle and reaching different positions on the product surface to form various texts and standards.

Unloaded droplets are directed to the recycling chute, re-entering the machine's internal ink circulation system. Inkjet printers can only use dot matrix methods and are limited by the number of print lines (up to four dot matrix lines).

It is difficult for them to print complex patterns and multi-digit letters or numbers on a small product surface, and even if they can print, the results are often difficult to discern.

High-quality laser marking machines can quickly and clearly print various unalterable graphics, texts and numbers on packaging materials of various textures (such as: wine bottles, bottle caps, etc.).

They can print special marks (graphics, text, codes) on the product or packaging, or use the special features of laser marking to effectively prevent the inter-regional circulation and sales of counterfeit products.

They can print numbers, barcodes, destinations, etc., on product packaging and cartons. When connected to a database system, they can also track the flow and inter-regional sales of distributors, which is beneficial to protecting the legal interests of manufacturers.

Comparing the two, it is clear that laser marking machines replacing inkjet printers are the trend.
