Advantages of CO2 Laser Printing
The fact that no ink is required is one of the most significant features of CO2 laser printing, which is suitable for printing soft capsules because the CO2 laser irradiates the capsule and turns the film white. Due to the characteristics of the printing method, CO2 lasers are suitable for printing soft capsules. In addition, there are other advantages unique to CO2 laser printing. On this page we will discuss some of the advantages of CO2 laser printing and what it has to offer that other printing methods do not.
No ink required and easy to maintain
Since printing is done by irradiating a CO2 laser, no ink is required as in other printing methods. The fact that no ink is required is one of the most significant features of CO2 laser printing. This eliminates the need for ink cleaning, which is a time-consuming process in factory production, and reduces the burden on operators. As a result, the time and operator effort required for item changeovers can be reduced, improving production efficiency.
No design roll required
In the case of offset printing, a design roll, an intaglio plate for ink transfer, must be made for each printed design and storaged. This is a consumable item and needs to be recreated periodically. On the other hand, CO2 laser printing, like UV laser printing, uses electronic data to create the print design, eliminating the need for a design roll.Furthermore, since the print design can be directly reflected in the printing process, there is no need for pre-production test printing or inspector confirmation as with design rolls.With CO2 laser printing, you can easily create and change the print design.)
High yield
Less than 0.01%* of printing defects are caused by CO2 laser printing. Since no ink is used, printing defects such as missing characters, double printing and ink transfer (smearing) do not occur.
Since there are far fewer printing errors, production is more efficient and waste can be reduced.

Halal support
In general, printing ink may contain alcohol or animal ingredients.
With CO2 laser printing, no ink is used, so there is no need to worry about the ingredients contained, and Halal compliance is possible.
Therefore, those who have reasons related to religious doctrines or beliefs can take printed tablets/capsules with peace of mind.
Environmentally friendly
There are no harmful emissions from the equipment.
It also meets the regulations of the Ministry of Health, Labor and Welfare for occupational safety during operation.
It is environmentally friendly due to the elimination of organic solvents, and contributes to ISO 14000.(ISO 14000 is the collective name for the international standards for environmental management systems issued by the International Organization for Standardization (ISO), the most widely used organization in the world.)
