The two major printing processes commonly used
01 What is lithographic printing?
Lithography is a printing method originally based on the immiscibility of oil and water. Lithography, also known as offset printing, is the most widely used printing method in the printing industry; the principle is to produce different printed products by pressing ink onto the printed paper through a cylinder with rubber adhesive.
It is suitable for posters, personal data, manuals, newspapers, packaging, books, magazines, calendars, and other black printed matter.
02 Features of lithographs
Lithographic plate-making work is easy and inexpensive; the color register is accurate and the printing plate is easy to reproduce; the printed matter is soft and soft-toned and can bear a large number of prints.
03 Lithographic printing method
Lithographic circular press type is also the printing layout flat, the pressure part is the cylinder type pressure cylinder, this printing method is very similar to letterpress printing in the same lithographic circular press machine.
The circular press type is the printing plate wrapped in a cylinder called the cylinder, another cylinder on the machine wrapped with rubber called the rubber cylinder, and the pressure part of the same cylinder type pressure cylinder.
Types of lithographic printing
Lithographic printing has lithographic printing, offset printing, Kikuchi printing, etc., but now basically only offset is left, and other types are rarely used.
05 Common Lithographic Presses
Lithographic presses are distinguished from other printing methods by the presence of a plate-dampening device. With the exception of lithographic presses, kotatsu presses, and proofing presses, they are all circular presses.
01What is aperture printing?
Aperture printing is also called screen printing, which is a printing method that uses a screen as the plate material. The graphic part of the printing plate can be printed through the printing ink, leakage to the substrate, forming the printing pattern of the printing method.
Aperture plate printing a wide range of this method can be used to produce prints, but also for household and industrial goods packaging printing.
02 Hole plate printing characteristics
Compared with letterpress, lithography, and other printing methods, screen printing has the unique advantages of fast plate making, simple printing methods, low investment in equipment, low cost, and a wide range of printing.
03 Hole plate printing method
Perforated printing is perforated printing, so the inking device is on top of the page, while the paper is placed under the page. Due to the different printing purposes, the layout can be made into a curved version according to the surface of the printed material, and any of the three major types of printing outside the limits generally can be achieved by aperture printing.
04 Types of hole plate printing
Hole plate printing using the printing plate is generally divided into two categories of transcription and screen version.
A transcription plate is of special wax paper, using an iron pen to carve out the word picture, or typewriter typing or using electric spark scanning made of printing plates. Printing with a transcription plate is commonly known as "oil printing". It is mainly used to reproduce documents for office use.
Screen printing plate, the layout is in the shape of a net, by the leakage of the film layer, screen, and screen frame. In recent years, screen printing has grown rapidly and is used for labeling, advertising, printing and dyeing, and map reproduction.
05 Common hole-plate printing machines
The hole plate printing machine is a representative printing equipment in the hole plate printing machine. The material for making the screen is not only real silk but also nylon wire, copper wire, steel wire, or stainless steel wire. It can be divided into flat screen printing machines, curved screen printing machines, rotary screen printing machines, etc.
