With the introduction of more stringent environmental protection laws and regulations, environmental inspections and production safety inspections, wave after wave, VOCs discharge charges, the majority of printing and packaging companies are facing increasing pressure, must pay attention to energy conservation and emission reduction and continuous improvement of the workshop production environment , The urgency of achieving alcohol-free printing needless to say.
However, "alcohol-free fountain solution" is not a new topic. As early as around 2005, domestic companies have tried to promote alcohol-free fountain solution. However, due to technical reasons, few companies have realized alcohol-free fountain solution. Too few, the results are unsatisfactory.
Fortunately, the research and development of domestic alcohol-free fountain solution did not stop there. A group of excellent enterprises went on and succeeded, continuously summing up experience, introducing foreign advanced technology, and combining the actual production environment of domestic printing companies and the use habits of captains. A series of relatively successful alcohol-free fountain solution products have been produced, and Fushley HD-31 is one of them.
What are the benefits of using alcohol-free fountain solution? You may say that it is more cost-effective than using alcohol, more environmentally friendly and safe, effectively improves the workshop environment, avoids the long-term corrosion of the rubber roller by alcohol, and so on. In fact, regardless of the management, technical and purchasing departments of printing companies, or the majority of printing consumable distributors, they are convinced of the advantages of the alcohol-free fountain solution. However, if an alcohol-free fountain solution is not smoothly used, the water level of German machines such as Heidelberg soars to 80 and 90, and it will be daunting to let the propaganda offensive do any better.
Adhering to the concept of "quality flying lion, serving the world", Flying Lion Company introduces German technology and revises the formula in accordance with national conditions, seeks breakthrough through "stability", and accurately controls the balance of water and ink through the interaction of multiple active agents to firmly hold down "Water level", whether it is shallow net or large field, should achieve the same water level as alcohol and maintain long-term stable printing.
At present, domestic general alcohol-free fountain solution has not encountered too many problems when used on Japanese machines, and it can print for a long period of time. Occasionally, the ink drying is too fast or too slow, the pH of the fountain solution is improperly controlled, or additives are used. Improperly caused the damage of the printing plate and the rotten net, but on the whole, Japanese machines have no suspense in the smooth realization of alcohol-free printing, which is gratifying.
German machines, such as Heidelberg, Roland and KBA, etc., to achieve alcohol-free printing, still need to be cautious and choose brands and manufacturers carefully. Because the brand of fountain solution that can truly achieve alcohol-free and maintain long-term stable printing on German machines is still very rare, there are generally high water levels. When the shallow screen and the large area coexist on the same page, the captain is helpless. occur. Taking a large color box factory in Guangdong as an example, the machine is mainly based on Heidelberg 102 5 + 1, 6 + 1, KBA 105 6 + 1 and other models. Almost every set will encounter spot colors, and at least one spot color In order to open up the international market and shape high-end image, the factory decided to realize green printing. It has tested dozens of different brands of alcohol-free fountain solution successively, but none of them succeeded. The problems occurred are mainly reflected in: the water level is suddenly large and small, it is difficult to control, the spot color group water level reaches above 80, and some of the color groups are printed with light ink, and the captain takes the method of ink and water to continue printing, and then there is a pile Mo Fei Mo and other faults.
In response to the problems encountered by the company, our company sent technical engineers to provide on-site guidance to assist in solving the problem. After checking the machine's water circuit to confirm that it is basically normal, configure the working fluid according to the specified proportion, turn on the water circuit refrigeration and circulation, and wait for the water temperature to reach the standard, start trial printing . After using FLEX® HD-31, the water level of the machine dropped by 10 compared with the previous level, which was basically the same as the water level printed with alcohol before. Due to the short work and spot colors, our engineers recommend regular water changes and cleaning of the water tank, and appropriately shorten the water change interval to ensure that the adverse effects of chemical components such as ink cleaning agents on the fountain solution are avoided.
With the increase of environmental protection pressure, green printing has become a hot topic, but the problems and contradictions of the domestic printing workshop environment, the captain's operation level, and usage habits and concepts are still very prominent. To truly achieve free alcohol printing, the majority of consumable dealers need to select manufacturers that have real product R & D capabilities and update and upgrade capabilities, have authoritative certifications, pass strict third-party agency testing and printing company tests and long-term use of products. Only when printing companies, consumable distributors and manufacturers work together to update their concepts, keep up with the times, and constantly innovate, can we truly usher in the era of green printing.
