Change direction of production machines

Over 30 years of witnessing transformation and changes in production machinery I am proud of Hong Kong people. 

The machines in the 1980s were all made in Hong Kong! And very durable. As the mainland opens up, machines 

become more and more advanced and efficiency becomes higher and higher. Previously letterpress printing (offset 

printing). Developed to gravure (copperplate) printing. Produce better quality plastic bags. Offset printing simple 

patterns, we can print up to 12 colors at the same time Copperplate printing can print portraits, and the efficiency

is quite high! Computer color matching. Both printing presses have their own advantages and strengths
