1. Mechanical structure (performance) and automation

For the feeder of modern single-sheet multi-color offset presses with speeds above 15,000 rpm, the importance is self-evident. First of all, it must be able to stably and reliably separate and transfer printing materials of different materials, widths, and thicknesses (such as paper, cardboard, plastic cards, and plastic film bases of different weights) one by one; second, to improve the degree of automation. Paper stack front-end detection, phase and skew correction, and edge gauge adjustment devices. For this reason, manufacturers have generally adopted their own high-performance paper feeders.

Up to now, several production plants have adopted vacuum suction belts for variable-speed paper transfer and precise positioning with pneumatic side pull gauges. They are especially suitable for commonly used paper media, but additional devices are required for paper jams and composite materials. For example, KBA's auxiliary press guide device is very suitable for the transport of thick paper.

To prevent paper feeding failures such as double-sheet, empty sheet, and skew, many manufacturers use photoelectric and capacitive control technologies, and KBA uses ultrasonic technology as a control method on some models, which is difficult to distinguish for some paper feeding failures, such as Thick paper, special printing materials and printing materials with thick ink on one side are very beneficial.
As the founding company of the double-diameter pressure roller and the transfer roller, the Planeta plant, one of the predecessors of KBA, has used this technology of low-curvature operation of this single-sheet multi-color offset press as early as more than 30 years ago. Our company's unit-type multi-color machine, this method has been respected and accepted by many manufacturers and evolved into some other forms.

For modern sheet-fed multi-color offset presses, whether the paper transfer cylinder is double- or triple-diameter, the gripping teeth row has a great effect, such as the double-diameter transfer roller on KAB Both rows of grippers are processed with the "cat paw" function, which saves the necessary adjustment of the row of teeth for the conversion of thick and thin paper during the printing process.

In addition, the installation of the blower and suction device of the air cushion suspension paper guide system matched with the paper transfer cylinder is also very mysterious. This is especially important when printing on thick cardboard and ultra-thin paper.

Of course, the transfer cylinder also has a function for the rapid overprinting of modern offset printing machines-it can be used as a correction for the deflection adjustment of the printing plate position, unlike the traditional unilateral deflection of the printing plate cylinder. Long-term damage to accuracy has played a positive role in the rapid response of overprinting, paper saving, and protection of machine accuracy.

Currently, only two or three production plants have this function. Several leading manufacturers of offset press production technology have their own characteristics in the design of the ink supply device for the printing part, but most of them use a multi-ink roller and double ink path for the ink delivery layout. Only KBA uses 5 on its main models. An inking system with a single ink path of different diameters depending on the plate roller. It is characterized by fewer ink rollers, only 15 rollers, and a large roller diameter. The first roller is connected to the water supply and wetting device by the roller, so that the ink and the roller are pre-emulsified, which can shorten the water-ink balance time and change the color of the printing ink. Respond quickly to reduce paper waste and cleaning time.

KBA's water supply and wetting device is also very characteristic, linear water transfer is its feature, with the use of rubber-containing water bucket roller and chrome-plated water transfer roller for continuous film water supply. This simple and fast water supply device can be used for low alcohol or alcohol free fountain solution printing without modification.

In addition, the constant temperature system of the inking device should also be the standard configuration of today's offset presses, because it can further improve the stability of the long-type live printing process, and can also do waterless offset printing to meet the future development needs of offset printing technology.

2. Accessibility and others

In addition to the online glazing and drying functions, modern offset presses also have a variety of online functions that can improve production efficiency, shorten printing cycles, save manpower expenses, and reduce intermediate storage. For example, the roll paper cutting device with vertical and horizontal cutters can be used for printing 4 + 4 color mail advertisements and newspaper supplements, punching and discharging devices, numbering mechanisms, inter-color printing devices, non-stop paper collection devices, etc. .

15,000 revolutions per hour should be the ideal rotational speed in the production of modern offset presses. At present, various manufacturers are trying to find out how to make better use of the overall benefits of the press under this printing, rather than simply increase the printing speed.

The full-sheet machine is a giant in single-sheet multi-color offset presses. Currently, only a few manufacturers are producing in the world, and only 1200mm × 1620mm specifications can be produced by KBA. The market demand for the full-sheet machine is long-term, whether in the field of commercial publishing and packaging printing, this demand is increasing, and the range of printed materials is also quite wide, including paper, cardboard, corrugated paper, etc. High-definition prints.

Meeting the needs of ergonomics, focusing on environmental protection, modern and future offset presses should be the key considerations. Because the ink, alcohol, powder spray, ultraviolet light, noise, etc. in offset printing have a considerable impact on the operator's physical and mental health and environmental protection. KBA took the lead in taking this step. At present, 105 machines have won the honor of the world's first green environmental protection machine and are named "ECOPRESS 2000".
