Computer Knowledge (Literacy)

Introduction

Advancement in ICT (Information Communication Technology, has made the world to be viewed as a global village. Regional economies, societies, and cultures have become integrated through a global network of communication, transportation, and trade), the Computers playing a major role, in this integration.

This integration of regions or nations of the world through this global network has made the world to be like a big village, where various nations are like clans in this big village, while the Presidents of the various nations are like heads of clans in this big village.

Therefore as it is any thing that affects one clan affects the other in this big village. This is what is actually happening in our world of today. A crisis in the Niger Delta of Nigeria affects the international price of crude oil, travels, etc.

This joining together of countries in the world economically, through education, society and politics, and citizens viewing themselves not only through their national identity but also as part of the world as a whole is what is Globalization.

Globalization is a process of interaction and integration among the people, companies, and governments of different nations, a process driven by a combination of economic, socio-culture, politics, international trade and investment and aided by ICT (Information Communication Technology), in which the Internet pays a major role, through the network of Computers cut across the globe or world

Globalization, has effects on the environment, on culture, on political systems, on economic development and prosperity, and on human physical well-being in societies around the world.

In our world today, there are few places a person can’t get to via telephone or the Internet. Because of modern modes of communication, citizens of a nation are more conscious of the world at large and may be influenced by other cultures in a variety of ways.

Time and space matter less, and even language barriers are being overcome as people all over the world communicate through trade, social Internet forums, various media sources, and a variety of other ways.

As a result of globalization, the world is viewed as one Big Town or Village called a Global Village. And members of the Global Village are called Global Community. One major medium which has brought people of all nations closer together is the Internet. Internet is the networks of Computers all over the globe, which enable people of the world (Global Community), communicate with each other. Internet is one part of ICT.

ICT has been the major driver of globalization. Advances in Information Technology, in particular, have dramatically transformed economic life. Information Technologies have given all sorts of individual economic actors-consumers, investors, businesses-valuable new tools for identifying and pursuing economic opportunities, including faster and more informed analyses of economic trends around the world, easy transfers of assets, and collaboration with distant partners.

As you are reading this article now, minds are communicating all over the world through the Internet, to achieve their desires. Buying and Selling, School Admission and Registration, Airline Travel Booking, Research of any kind, Banking, Emails, looking for Employment, Information, etc, are all going on through the Internet.

Being Part of the Global Community

From the understanding above, no one in this present world, can succeed if he is she is not a member of the global community. To be a member of the global community, you must:

1. Be Computer Literate

2. Learn how to use the Internet

3. Own a Personal Computer (Desktop or Laptop)

Computer Literacy

Computer literacy is defined as the knowledge and ability to use Computers and technology efficiently. Another valuable component of Computer literacy is knowing how Computers work and operate. This later component is for advanced users or operators who may want to be Computer engineers. Knowing and having the ability to use Computers is mile stone into the global community.

Why Is Computer Literacy Necessary?

There are a lot of things you will need the Computer for directly or indirectly in this present age of ours. Either you use it directly or someone is using it on your behalf. Some reasons why you have to be Computer literate are as listed below:

1. When looking for job, your employers require that you be Computer literate, as Computer could be a basic tool you will have to use.

2. In most places of business, Computer is standard. For example, in the banks Computers are used for banking transactions and to look up customer’s account information. In some auto repair shop Computers are used to assess electronic and other faults in cars.

3. In schools Computers are used for student’s registration and admission, accounting, exams and records. School libraries are database of books. No more use of library cards.

4. In some Hospitals and Clinics patient information are stored in Computers. Doctors must know how to retrieve such information to treat a patient.

5. To send or receive electronic mails you need to learn how to use the Computer and the Internet or you pay someone to do it for you.

This list is endless. It is in your best interests to start learning to use the personal Computer now. It will help you get a job and it will help you advance in your career.

Computer literacy does not mean you need to know how use every single piece of software you may encounter. It does not mean you need to know how to write programs or network Computers. You just need to know some basics:

1. How to Start the Computer

2. How to use the OS (Operating System) running in your Computer, Windows, Mac or Linux.

3. How to open Application Software such as Microsoft Word, Excel and PowerPoint. Create, Save and Open Files.

4. How to Exit or Close an Application Software and open another.

5. How to properly shutdown the Computer after usage.

6. How to use the Internet to Browse the Internet, send and receive email.

7. How to listen to Music and play Video in your Computer.

8. How to handle your PC (Personal Computer).

When you learn how to use the computer, you will have some sort spot for it in your mind, when you come to appreciate how easy it is to use the computer and how useful it is. Then the fear that it is impossible or difficult to learn how to use the computer would have been a thing of the past.

I remember when I was teaching a very good friend of mine how to use the Microsoft Word and the Mouse. It did not come so easy. But because she had made up her mind to learn, it did not take time for her to start using the tools. One day I went to her office to see her, just to find out that the typewriter she so much loved was under the table. Then I ask her how is the mouse doing? And she smiled. Her masters programme was on Computer Networking. This is the joy of learning how to use the PC.

It is your duty to bring out the very best in them. So help them with their curiosity and inquisitiveness about Technology. They will feel gratified and fulfilled, which in turn will give you immense joy and bliss.

Sublimation Printing and the Advantages and Disadvantages of This Print Method

Sublimation printing is the process where photo quality images, graphics or text can be transferred to a wide range of items including garments, metals, acrylics to name a few via heat transfer.

Specialised sublimation ink must be used as when this ink is heated it changes its state from a solid to a gas, without the need for the liquid phase. When this gas come into contact with polymer fibres it is abkle to pass through them, which in turn permantly dyes the fabric.

For the Sublimation process to work effectively the items to be printed must be first poloymer coated or already polymer based. (ie poloyester tshirt)

Because almost any item can be polymer coated this process alows prints onto almost anything, such as ceramic mugs, glass, metal sheets, acrylic and other unisub items like mousmats, coasters or phone cases to name a few. Sublimation printables are constantly updating, as long as the item can be polymer coated and heat pressed it is highly likely it can be sublimated.

Because of this sublimation printing is vast becoming one of the most popular printing methods within the industry.

The advantages of sublimation printing are as follows;

Sublimation method allows you to print full color images onto hard surfaces with a polymer coating.
Screen printing can be a complicated learning process and become quite messy where as sublimation is an easier process to master.
Sublimation allows the use of a full colour spectrum.
Cost the same amount to print 1 item that it does to print 1000, meaning the customer doesn’t need to order minimum order quantities, making sublimation the perfect print process for small business looking for promotional items, or the gift personalisation market.
The customer can completely customise. Sublimation printing does not require screens or specialist plates, meaning its a simple process to customise designs with any elements that change such as individual names, team numbers.
Sublimation can be a quick process depending on order which could allow companies to offer same day or in some cases, same hour printing.

As with anything there can be disadvantages, and sublimation is the same. Some of the disadvantages for sublimation printing are as follows;

The inks can be quite expensive to buy compared to other OEM ink printers, which is usually factored into the pricing of sublimated products.
The items to be printed need to be either made of polymer fabrics or coated with polymer to ensure the sublimation process works effectively.
Printables are required to be ideally white or very lightly couloured. Because the colour is dyes into the fabric sublimation printing cannot be used on dark printables such as black tshirts.
Although with the sublimation process it is possible to access the whole colour spectrum, it is very difficult to mange the colours on the printers, this has been helped over the years with the introduction of the powerdrivers.

Sublimation is really coming into its own and is a rapidly growing sector, its clear to see with the advantages raised above why this is.

Importance of Screen Printing Services

Any successful commercial printer needs to provide intelligent marketing solutions to her customers and inspire them to demand innovative driven print. It is important to note that the future of imaging is dependent the ability of commercial screen printers to lead, excite and invigorate the marketplace.

Screen printing can be defined as a printing technique where a woven mesh is used to support ink-blocking stencil. The stencils are designed to transfer ink and other printable materials that are pressed over the mesh onto the substrate. After that a roller is then moved over the screen stencil, pumping or forcing ink through the woven mesh threads in the open areas.

Screen printing can be done on T-shirts and many other garments to celebrate and reflect vivid senses, sense of fun, sense of spirit and sense of colors. A number of client responses have been made over the years. This has made this service to motivate many prospects and can be evidenced by a large number of orders placed.

It is important to note that screen printing is a cheap and easy cost set-up which rarely needs any technical arrangement. Most companies that offer these services print effectively copies of screen designs on different garments. Both professional and amateur printers normally use widely a screen printing press. One of the common examples is the industrial-grade-automatic printers. Such type of machines needs minimal manual labor with increased production.

The following are some of the key benefits that are associated with the process of screen printing:

Good results

With good printers it is possible to have high quality. This is so because they are free Lint free and Ultra-low fiber. This also makes it easy to release and maintain clean surface areas.

High Absorption

There is a need for a high absorption for capability and removing of the paste. The paste is usually made of aluminum, silver, and copper among others.

Mesh Pattern

The wipers widely used have an amazing and unique mesh pattern. This ensures there is an excellent paste removal.

Cost Effective

This is in comparison to the common digital printers that are used in the market. This is also because they create big holes around the pockets.

Green

It is a good idea to use materials which can be reused and revived. Therefore eco-friendly and biodegradable screen printers should be used and use 100% natural cotton. This is because our environment is quite important and means our prosperity.

What Is A Giclee Print And What Is Its Life Span?

What is a giclee print?

Giclee prints are digital reproductions of works of fine art that are usually printed on a canvas or on watercolour paper. Giclee printing refers to an advanced method of printing whereby these works are produced to have a much higher quality and much longer lifespan than those produced by a standard inkjet printer. The prints are created from a highly detailed digital file which is sent to a specialised printer that is much more advanced than a typical inkjet printer and is capable of handling several different types of printing materials.

What’s the difference between a giclee and a standard inkjet print?

The document from which the giclee is to be printed has to have a resolution greater than 300 DPI (dots per inch). Any camera or scanner used to capture the image must also have a resolution greater than 300 DPI. The substrate the work is printed on to has to be of archival quality because archival paper lasts much longer and reproduce colours much more effectively than standard paper. Giclee prints are usually created using professional printers and pigment-based inks. These inks have a much longer lifespan than dye-based inks and are thought to last over 100 years without fading. The printers used to create giclees can produce works in a much larger format and can typically hold up to a dozen ink cartridges, allowing for highly detailed works to be produced.

Where does the term ‘giclee’ come from?

The term ‘giclee’ comes from the French word meaning a spray or squirt of liquid. It was first coined in 1991 by the printmaker Jack Duganne to refer to the process of creating prints of fine art using IRIS printers, a process which was invented in the late 80s. Nowadays the term ‘giclee print’ can refer to other types of inkjet printing and works of art that are created digitally on a computer program, such as Illustrator or Adobe Photoshop, before being processed on to a substrate.

What’s the lifespan of a giclee print?

It is currently uncertain how long a giclee will last because the technology used to create them is fairly recent. Some websites say a giclee will last over 100 years, while others offer a more modest estimation of over 35 years. Some sites do mention aging simulations carried out in laboratories to try to determine how long giclees will last, but there is no way to verify any claims. Obviously giclees will last if they are cared for well; it can also be safely assumed that they will last considerably longer than inkjet prints thanks to the quality of the printers, archival paper and inks used to create them.

Why go for giclees?

One of the main advantages of giclees is that they can be created on-demand as the process is digital. Artists can therefore create their own prints whenever they want with ease. This is a much better option for artists who might not want to mass-produce their works. Once a file is digitally archived, it won’t deteriorate in quality or gradually fade like physical works do. Each giclee print can be customised, whether it’s printed on to a number of different substrates or whether its size is altered. Giclee prints are very popular thanks to their high quality and the fact that they can be more advantageous to artists than standard methods of printing. Giclees are commonly seen in galleries and exhibitions all around the world.
