Discussion on the success and failure of Rigid Cardboard Cigar Paper Boxes lithography and alcohol free printing

With the introduction of more stringent environmental protection regulations, environmental supervision and safety production investigation wave after wave, VOCs pollution charges, the majority of printing and packaging enterprises are facing increasing pressure, we must pay attention to energy saving and emission reduction and continue to improve the workshop production environment, and realize the urgency of alcohol-free printing need not be added.

However, "alcohol-free fountain solution" is not a new topic, as early as around 2005, the relevant enterprises in China have tried to promote alcohol-free fountain solution, but due to technical reasons, the real realization of alcohol-free printing enterprises are few and far between, the results are not satisfactory.

Fortunately, the research and development work of the domestic alcohol fountain solution did not stop, a group of excellent enterprises, after another, constantly summarize experience, the introduction of foreign advanced technology, and combined with the actual production environment of the domestic printing enterprise and the captain use habits, developed a series of more successful alcohol fountain solution products, Frushelai ®HD-31 is one of them.

What are the benefits of using alcohol-free fountain? You may say that it is more cost-effective than the use of alcohol, more environmentally friendly and safer, effectively improve the workshop environment, and avoid the long-term corrosion of alcohol on cots. In fact, regardless of the printing enterprise management, technical and purchasing departments, or the majority of printing consumables dealers, are convinced of the advantages of alcohol-free fountain solution. However, if an alcohol-free fountain solution is not used smoothly in practice, the water level of Heidelberg and other German machines often rises to 80, 90, no matter how good the publicity campaign is, it will be prohibiting.

Flying Lion company adhering to the "quality flying lion, service the world" concept, the introduction of German technology and combined with national conditions to modify the formula, to "stability" for breakthrough, through a variety of active agent interaction, precise control of ink balance, firmly press the "water level", whether shallow net or large field, do the same water level as the use of alcohol and maintain long-term stable printing.

At present, the domestic general alcohol-free fountain on the Japanese machine use do not encounter too much problem, can long-term stable printing, occasionally encountered ink drying too fast or too slow, fountain solution pH control or improper use of additives caused by plate damage, bad screen situation, but in general, the Japanese machine smooth implementation of alcohol-free printing has no doubt, to congratulate.

German machines, such as Heidelberg, Roland and Gaobal, achieve full alcohol-free printing, but also need to be cautious, careful selection of brands and manufacturers. Because the market can truly achieve full alcohol free and maintain long-term stable printing of the fountain liquid brand is still very rare, the widespread existence of high water level, shallow net and large field coexist in the same layout, the captain is at a loss. Taking a large color box factory in Guangdong as an example, the machine is mainly based on Heidelberg 102 5+ 1,6 +1, Gao Bao 105 6+1 and other models. Almost every set of plates will encounter spot colors, less than one spot color, more than 3-4 spot colors; In order to develop the international market and create a high-end image, the factory decided to realize green printing. It has tested more than a dozen different brands of alcohol-free fountain solution, but none of them succeeded. The problems are reflected in: the water level is difficult to control, the water level of the spot color group reaches more than 80, and the ink color of some color groups is light. The captain takes the way of large ink and large water to continue printing, and then there is a failure such as heap ink flying ink.

In view of the problems encountered by the enterprise, our company sends technical engineers to guide on the spot to help solve the problems. After checking the machine waterway to confirm that it is basically normal, we configure the working liquid according to the specified proportion, and start the water refrigeration and circulation. After the water temperature reaches the standard, the machine will start the trial printing. After using the Frashlay ®HD-31, the water level of the machine is 10 lower than before, and the water level is almost the same as the water level of the previous printing with alcohol. As the live parts are mainly short single and spot color, our engineers recommend regular water change, clean the water tank, and shorten the water change interval, to ensure that the ink cleaning agent and other chemical components on the fountain working fluid adverse effects.

With the increasing pressure of environmental protection, green printing has become a hot topic, but the problems and contradictions such as the environment of the domestic printing workshop, the operation level of the captain and the use habits and concepts are still very prominent. To achieve full alcohol free printing, it is necessary for the majority of consumables dealers to select manufacturers with real product development capabilities and upgrading strength, with authoritative certification, and through strict third-party agency testing and printing enterprise testing and long-term use of products. Only printing enterprises, consumable distributors and manufacturers work together to update the concept, keep up with the pace of The Times, and constantly bring forth the new, in order to truly usher in the era of green printing.
