Offset printing is using the CMYK system, processing the four basic colors needed to print the image, a processing being made on the basis of halftoning. The paper surface is partially covered by circles in the four basic colors, which are small and dense enough that the eye will mediate the effects of the white surface and of the surface covered by the circles, creating a unified look.
It is good to know that in terms of chromatic images are directly influenced by media type characteristics (degree of white, glossy, matt or metallic, etc). The more absorbent is the support, the less the contrast and brightness of the printed image. Printing is influenced also by the colour of the paper or paperboard used.
In terms of offset printing presses there are many top brands offering many innovative solutions in the area. In the printing industry, Mitsubishi printing presses have a long way tradition, especially in offset. Their flagship in this particular area are however the Diamond series. One of the models released in 2008 stands out of the crowd: Diamond 16 Max+.
As the name suggests, it is an improvement of the previous model, Diamond Max 16, than a completely new product but even so, the improvements are significant. First, it works on the “one button operation”, which allows a not so highly trained operator to use it.
Not to be neglected: improving the quality of printing, shortening preparation times, reducing losses and improving safety.
In terms of preparation time, the Max SimulChanger system cannot be overlooked, for it allows a complete change of plates in 60 seconds (a world record, as stated by the manufacturer).
As for color management, Max Diamond Eye examines not only the patches, but compares the values with those reported by prepress and adjusts the inkwell. In addition, the operator has access to MAX Color Navigator, which allows fine tuning of colors by touch-panel (a system received the 2006 Technology Award from the Japanese Society of Printing Science and Technology).
For what kind of projects would Diamond 16 Max+. be the most appropriate? Well projects such as: Printing of magazines, brochures and newspaper inserts.
Another successful series is Daiya which were manufactured mostly between the 1980’s and 2000, so there’s a great chance to find these machines listed especially on websites dedicated to used Mitsubishi printing presses . Perhaps the most outstanding features for a sheet-fed Daiya are met within the MITSUBISHI DAIYA-3H.
This machinery was built having in mind the most important job in producing color. In order to match an aim colour easily, the company developed for this model, a spectro-measurement sensor and ink control system.
Thus the efficiency of color control was enhanced by minimizing the deviation between the aim color and the measurement color. This system is primarily based on accuracy because it gives an outline of measuring and ensures the flow of ink control. All these features make the Mitsubishi Dayia-3H one of the best model among the Dayia series on the market.
