How offset printing happens – a brief introduction on offset printing consumables!

Are you into the printing business? Then you must have a thorough idea about how all of the various kinds of printing take place. And when it is printing that is being talked about, offset is most popular and widely used for every commercial purpose. When you read something like a newspaper, a story book or a magazine, do you ever stop and think how that publication came to existence. It is not the writer or editor, who takes all the pain of bringing an idea to words. The printers too are involved in this process, where they have to use various offset printing consumables to make printing happen.


What is involved?

Offset it one of those technologies that has been into existence for more than a few decades. Although many other advanced printing technologies have evolved in the mean time, offset still is the most trusted and most used printing option that printers trust, when it comes to bulk productions. But before you get the final product ready, there are quite some factors associated with this.


Offset printing involves huge pounds of rolls of paper as it is always meant for bulk printing, wash up blades, rubber rollers, plates and specific chemicals and inks for the print to be done. When a graphic design is made, it is first transferred into a film negative. This film negative is then used to make the metal plates that will do the task of transferring the texts and images onto the paper.


What is the process?

When paper is fed into a printing machine, metal plates are washed with ink and water. The ink gets bound to the design on these plates and water gets to the white portion of paper. With the ink, oil is mixed. This is done in order to make sure that the ink does not get dissolved with the water; but repels due to the presence of oil. It is very important to mention at this point that the ink that is used in this entire process is of high quality and of quite a different texture. It is the most crucial elements of the offset printing consumables.

Usually there are numbers of plates used to transfer colours to the rollers or blankets and then onto the paper that is being used for printing. In case there are four colours being used, there will be four plates like cyan, yellow, magenta and black. These plates offset or transfer that design to those blankets or rollers and then they are printed on paper.
After the wash up blades, rollers and cylinders have performed their task the papers, which are wet are taken to dry up. But in this entire process, it is imperative that you choose high quality equipment and machine parts made up of either rubber-metal, plastic or poly-urethane. For smooth and perfect finish, using blades with sharp and straight wiping edge is very crucial.

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…

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…
