Printer

Abstract

The invention provides a novel single-paper press which is different from the existing offset press in the aspects of two functions: first, an ink-controlling device for and adjusting and controlling ink supply of an inking roller is not required to adjust and control mass color in the whole process of printing due to the ink supply of printed material so that automatic mass color control is achieved; an electric device which can be used for heating and adjustment is arranged in an ink-stirring roller and an ink-ending controlling device; second, the new process in which the printing can be completed only by taking printing stocks in an exchange way changes the original multi-exchange process. In the attached drawing, only a double-side printing monochromatic group is provided; the press with the printing process can be connected with two, four, five and six color classes as well as connected with double-side printing and single-side printing. Moreover, the press provided by the invention can be produced in large size and can print thick material, namely such thick plane plates as PVC, metal, etc; furthermore, the press ensures that the offset press plays a more important role in commercial products such as decoration, packaging, etc., of home appliance.

Description

Technical field: [0001] This patent relates to the ink supply, ink recovery and control ink volume system of the printing machine, the water supply and water recovery control water value device system and the printing method of the sheet-fed printing machine. Background technique: [0002] There are two types of offset printing machines (including paper and iron printing machines), the sheet-fed type and the rotary type, both of which use the adjusting screw on the ink supply fountain to control the amount of ink released, the speed of the water to control the speed of water, and the printing method. The printing is completed by passing the printed matter through multiple impression cylinders. We know that to print a good color printed matter, we must ensure the balance of water and ink, and adjust the printing pressure to print qualified products. Now the printing machine must pass a certain printing process. It takes a few days to adjust the balance of the ink color of the...

Problems solved by technology

The water landing balance of the water landing roller is also related to the quality of the product. Now the printing machine uses speed regulation to control the water volume, so there is an unstable factor of water landing, which causes the problem of too much water and less water. Affects the inking effect, thereby causing the problems of printing quality and waste. The water eliminator of the present invention is to ensure a good supply and demand relationship of water. When the first water supply roller (B3) is fully watered on the printing plate (Water splashes can be seen on the printing plate), the second water landing roller (B1) has two functions, one is that the second water landing solves the problem of insufficient water landing, and the other is that the water eliminator is in the state of adjusting and positioning Recycling the excess water from the water roller, generally no water splash can be seen on the printing plate, so that the printing plate can reach the standard amount of water, so that the inking roller can better ink and print good products. This new type of printing machine is used in this Scientific and technical methods maintain a balanced amount of water and ink, so that a good balance of ink and water can ensure the quality of printed matter and greatly reduce the waste of materials.
