Methods & Types of Offset Printing Press

A printing press is a device that is used to print an image onto a surface like cloth or paper. This printing is carried out using ink that sticks to the surface and frame or plate that contains the original image which is to be printed onto the surface. Printing press is one of the most valuable inventions in human history and the Heidelberg offset press is one of the best machines in this category.


Various methods of offset printing
  1. Blanket to blanket: This system consists of two blanket cylinders and there are no impression cylinders used in this process. Through this type of printing, the paper is passed in between the two cylinders and both of the sides can be printed at the same time. This system is efficient as both sides of paper are covered in a single process and both the cylinders act as impression cylinder for the other.

  2. Variable size printing: Offset printing consumables like the inserts, cassettes and removable printing units are used when one side or both sides need to be printed.

  3. Blanket to steel: This system consists of both the plate and cylinder. The pressure applied to both the layers is quite accurate and the pressure applied is very slight. The cylinder presses the substrate when it comes in contact with it. This is mostly used when a single colour is to be used while printing.

  4. Dry offset printing: A plate which already has all the patterns on it is used. This plate is not used on the substrate directly. The rubber blanket only comes in direct contact with the substrate.

  5. Keyless offset: The ink which is left as residue after each process of printing is cleared off. Fresh ink is used for each printing process and this system is mostly used for newspapers.

Types of an offset press

There are several components of an offset printer and all the parts of the Heidelberg offset press are the best. The perfecting press can print on both the sides and is known as the duplex press. It is faster and much more efficient when compared to numerous other printing systems. It can print only in a single pass as the machine is branded.


Duplicators

These are lithographic presses and are of good quality and also produce image or text in only a single colour or two colours. Many manufacturers have created popular models for these devices. These devices are known for their speed. It is quite quick to print and also create numerous impressions of characters in a second.


Printing-inking system

This system is made up of many systems and the dampening, inking and plate systems all are used. Offset printing consumables are present in plenty in this device. A combination of numerous systems makes this system quite efficient and allows it to deal with each type of system. It is necessary to follow all the above-mentioned processes and then the blanket system is also implemented. Without the blanket system, it cannot be referred to as an offset system.

AMOLED display coming to Samsung Galaxy Tab range

This is a guest post by Erica about the arrival of AMOLED display to Samsung Galaxy Tab range.Samsung could be transplanting a seven inch AMOLED screen into an upcoming addition to its Galaxy Tab range of tablet computers.

You may have experienced an AMOLED display in a small portable device before as Samsung, Nokia and HTC have all used them in smartphones to date. However, the expense of producing AMOLED screens has prohibited them from appearing on larger devices like tablets, until now.


The seven inch Galaxy Tab was launched last year but an update with an AMOLED screen would be most welcome, cutting energy consumption and improving colours and contrast ratios across the board.


The rumours about this device state that it will run Android 3.0, feature a three megapixel camera on the rear, a two megapixel snapper on the front and have a display resolution of 1024x600 which is not bad for a device of this size.


The hardware powering the new Galaxy Tab will consist of a 1.2GHz processor w…

Building Blocks for Virtual Businesses : Key technological systems you must have to succeed in the remote business world

This is a guest post by Ripley Daniels about "Key technological systems you must have to succeed in the remote business world.

Whenever I tell friends I had a tough day at the office, they laugh at me. That's because they know I don't really have an office. I work very hard but I work for a company that is completely remote. Only a few of my co-workers ever go into an office at all and when they do, it's only for short periods of time. Our "office" is a virtual one. To us, the traditional office workplace is a thing of the past, alongside Tyrannosaurus Rex, the slide rule, and telephones where you stick your finger in a hole and turn a dial.
Unfortunately, none of this prevents me from having tough days. I still have them. But the reasons have nothing to do with the fact that my co-workers and I don't have a brick and mortar edifice that we can use to plan, strategize, hold our meetings, make presentations, discuss sensitive business topics, build relatio…
