As early as the 1950s and 1960s, the predecessors of the domestic printing industry had introduced this printing method to the country, but at that time it had another name: flexographic printing press. Due to the printing knowledge and related supporting reasons at that time, flexographic printing failed to develop. On the contrary, the lithographic printing presses and gravure printing presses that entered China during the same period were recognized.
Until the 1970s, flexographic printing technology developed rapidly after major breakthroughs in printing plates and ceramic anilox rollers. Most packaging printing in Europe and the United States began to switch to flexo printing. my country has also introduced related flexo printing equipment from abroad in the 1990s, and has developed rapidly in recent years.
The structure of the flexographic printing machine, to put it simply, is currently divided into three types: stacked, unit type, and satellite type. Now we will introduce the satellite type flexographic printing machine in detail.
Satellite-type flexographic printing presses are the flexographic printing method that is less used in China and its development is slower. This has a greater relationship with the industry’s understanding of it and historical reasons. In fact, satellite flexographic printing has many advantages, except for the advantages of high overprinting accuracy and high speed. In fact, there is a very big advantage when printing large-area color blocks (solid), which is comparable to gravure printing.
Due to the use of ceramic anilox rollers to precisely control the ink loading, when printing large solid color blocks with flexographic printing, it only needs about 2~3g ink per square meter without affecting color saturation. The gravure printing needs 5g/m2 or even higher (the data in the article shows 4~6g/m2), plus the supporting solvents, the actual cost of ink is far higher than the flexo printing method. Another advantage is that the user is worthy of concern-energy consumption. Due to the relationship between the flexographic printing structure, ink, ink volume, etc., it does not require too much heat to completely dry the printed job. . So usually an 8-color flexographic printing machine, under the premise of a speed of 300m/min, the power of the electric heating method used does not exceed 80KW/hour.
Other printing methods usually require more than 150kw/hour of energy consumption, or even higher. This can be said to be very good news when the current domestic electricity consumption situation is not optimistic.
