RGB verses CMYK Colours
For the colour printing of your digital files, you need to provide the graphics and image in the correct colour mode. Many software programs allow you to work on RGB colour or CMYK colour. RGB colours or Red-Green-Blue colours are familiarly known as the primary colours of the light. This colour combination can be seen on your tv or computer monitors. The digital cameras and scanners also produce pictures with Red-Green-Blue colour combinations. Red-Green-Blue colour mode should be in use while taking photos that are to be viewed on a monitor, emails or CD.
All the colours of the light spectrum are created from the primary colours, but monitors can display only a limited colour range from the visible spectrum. Light is emitted by the monitor, and the ink recognises only a certain wavelength of colours. All three primary colours are combined to create white. If all three primary colours are missing, then the light will show as black. By combining a variety of intensities of RGB colours, each combination results in various colours. The monitor of a television or a computer consists of small units called pixels. Every pixel contains three units of light, and each unit represents red, green and blue.
We can’t actually see the individual pixels with the naked eye as they are too small. But each pixel is made by applying correct values of RGB, and without the proper values of the colour units, you will not see any image displayed on the monitor. The values of RGB colours are calculated mainly by three methods. The first method is to set them using different numeric values. The numeric values used for this purpose are the values from 0 to 255, and this is the easiest method of the three.
The second method is the use of hexadecimal notations. This method is mainly used for HTML and other languages of the computer. These notations follow a logical pattern. The hexadecimal notation consists of six characters, with these characters being divided into three. The first pair represents the red, the second pair green and the third pair as blue. Each pair is represented by a hexadecimal number (0-9) and the letters (A-F). The third method is the percentage in which a certain percentage represents each colour. The programme translates these percentages into suitable values ranges from 0-255.
CMYK colours or Cyan-Magenta-Yellow colours are subtractive colours, whereas RGB colours are additive colours. Additive colours are referring to light, whereas subtractive colours refer to inks, paint or pigment. CMYK mode is used for printing as all kind of printers use subtractive colours to result in a variety of colours. When three additive colours are combined, the combination will produce white colour. But when three subtractive colours are combined, the combination produces black colour. This difference results in a large diversity between the print and the onscreen display. Additive colour projects the light from the monitor, and if more light is projected from a specific pixel, it will be closer to the pure light. Regarding printer inks, they absorb light and reflects only the wavelengths of light that is associated with the colour of the ink.
The inks of the printer take away the non-essential wavelengths from the light that falls on the ink. The remaining light will return to the eye, resulting in the impression of a variety of colours. If you are mixing a number of colours, then more light will be absorbed by the ink and a lesser amount of light will be reflected to the eye, which results in darker colour. Black ink produced by the CMYK colours is not a strong black. So you must add some black ink to produce the best results for printing true black. To get a darker tone of any colour, you need to add black in CMYK mode.
What about the lighter shade of colours? As white ink cannot be created using CMYK colours, you need to work under the hypothesis that you are printing the colours on a white paper. Because small dots of ink are used to print images the inks are used in lower percentage to receive lighter shades so that more white is seen among the dots. The values of CMYK colours are calculated with the help of four different percentages. The values of each percentage should be between 0 and 100 so that the total percentage of the ink values can be up to 400%. However, when the total percentage does reach 400%, the ink takes more time to dry. Therefore, the total percentage of the ink shouldn’t be more than 300% in CMYK mode.
Both the colour modes have their own limitations. The images developed using RGB mode can’t be converted smoothly into CMYK mode because of the brightness of RGB colours. Similarly, CMYK colours cannot be translated into RGB mode as the sharp look of RGB colours is missing in CMYK mode online. This is the reason why RGB colours are used in monitors and CMYK colours are used in printers.

While the question of which country has the greatest quality of life is often approached subjectively, a careful analysis of several factors is important to be able to predispose which one is the best objectively speaking. An objective approach would be to rate the distinction of life through the Human development index (HDI), which is an annual report, acquit by the United Nations Development Fund.
According to the latest human development report by the United Nations, the country that has the great quality of life in terms of HDI is Norway. The HDI goes beyond the GDP (Gross domestic product) to measure how developed a country is. It takes into account three important factors; life expectancy, adult literacy and education, and standard of living measured by purchasing power parity (PPP).
It provides a heterogeneous view of the relationship between income and well-being.
Norway ranks number one in the human development index due to the following reasons:
Norway scored a 0.98 in the HDI, with 1.00 being the highest. The country has the highest purchasing virtue parity.
Norway also has one of the lowest emigration rates. With only 3.9% of its citizens migrating to other countries.
As of the 2010 report, Norway has a total population of 4,898,600, which is pretty ground-level compared to other countries. A good number of their population has high PPP rates.
Public education in the country is free, regardless of nationality. This means that everyone is given access to free education regardless of culture, religion, race and stature in life.
Norway has the second highest GDP per capita next to Luxembourg and the third highest GDP in terms of Purchasing power parity in the world.
The country is prosperousin natural resources including; petroleum, minerals, hydropower, marine life and forests.
While the cost of living in Norway is roughly around 30% higher than in the United States and about 25% higher than the United Kingdom, Norway still holds a place as one of the countries with the flying standard of living in the world.
Norway has also been ranked to be the world’s most well-functioning and stable country.
Based on the aforementioned reasons, there is no doubt that Norway is indeed the country that offers the best quality of life in the whole world. With a well-functioning economy, excellent public school system and excellent purchasing power parity, there is no vacillation that Norway would remain on top even for the next years to come.

Sphere: Related ContentTips to Creating a New Business Logo
A logo is a very important step to creating a business. It is the face of your business. And like your face expresses the tone of your business, indicates the service and reveals the professionalism or lack there of.
People spend a lot of money on the creation of their logo and walk away with no artwork files. Then a couple months down the track when they require to put signage on their new building they cannot track the design studio down that formulated the original logo for them and so incur costs to have it recreated. This is unnecessary and may cause obstacles when trying to replecate the logo exactly as determined originally.
We have created some basic tips you for to think about when creating a logo. Hopefully these will help you from experiencing any future obstacles.
Tip 1
First things first - you need to decide if you would like your logo to have an accompanying icon. It is suggested that if your service or product name is not in your business name then perhaps an icon will assist in conveying a clear message across to your target audience.
An icon can add an extra element to your branding in that you could use the icon on its own on collateral where perhaps you are sighting for a more illustrative finish without losing recognition.
A excellent example of this is the well-known and executed Fedex logo.
Tip 2
Colour can be an extremely important decision as it not only could change the output costs but can also limit your output use. Think about the end result and what you will be putting your branding onto in the future. Make sure your designer is aware of this as they should design accordingly.
Tip 3
Confirm you get a back up disk of your logo as a master file and confirm that it includes all the files required for the different printing formats.
Creative software updates frequently and some programmes become obsolete. Make certain you have a copy of your logo as a PDF - with the text converted to curves.
Tip 4
Using images in your logo is not very easy to regulate. For example it is troublesome to reverse into black and white. Images also have limitations when it comes to size - they can only be reproduced to a certain size before they start pixilation.
Tip 5
Using gradients in your logo is not recommended. This too can have limitations when it comes to output for ie: gradients are hard to reproduce when embroidering fabrics.
Tip 6
Confirm sure the font is legible. Some logos need to be reproduced on small pieces of collateral ie: post stamps. It is important that in this case the text is
legible.
Tip 7
Assure that you collect a copy of your logo in CMYK high resolution 300 dpi (for printing use) and RGB 72 dpi(for web use).
Tip 8
It is important to have a style guide of your logo. It will clearly show you how to use your logo so it looks exactly the same every time it is reproduced. This allows you to keep your corporate image consistent.
Tip 9
Make sure that you get a letter from the design studio declaring that you own the copyright to your logo.
If you follow these tips then not only will you get a well-designed logo but you will also own the artwork. And when it comes to reproducing your collateral you will be doing it the most cost effective way.
