RGB verses CMYK Colours

For the colour printing of your digital files, you need to provide the graphics and image in the right colour mode. Many software programmes will let you to work with RGB colour or CMYK colour mode. 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 t.v. or computer monitors. The digital cameras and scanners also produce images using Red-Green-Blue colour combinations. Red-Green-Blue colour mode should be in use while taking photos that are to be viewed on the monitor, or by emails or CD.

All the colours of the light spectrum are created from primary colours, but monitors can display only limited colour range from the spectrum able to be seen. Light is emitted by the monitors, and the printing ink recognizes only a certain wavelength of colours. The three primary colours are combined together to create white. If all three primary colours are absent, then the light will appear as black. By combining a variety of intensities of RGB colours, each mixture results in differing colours. A monitor of a television or a computer is made up of small units called pixels. Each pixel contains three units of light, and each unit represents red, green and blue.

You can not see individual pixels with the naked eye because they are too tiny. But each pixel is developed by applying proper values of RGB, and without the proper values of the colour units, you will not see any image displayed on the screen. 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 superior method of the three.

The second method is by using 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, and these characters are 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 program 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 refer to light, whereas subtractive colours refer to inks, paint or pigment. CMYK mode is used for printing as all kind of printers are using subtractive colours to result in different colours. When three additive colours are combined, the combination will produce white colour. But when three subtractive colours are combined, the combination produces black. This difference develops a wide diversity between the print and the monitor display. Additive colour projects light from the monitor, and if more light is projected from a particular 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 our eyes, providing 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 your eyes, and that results in darker colour. Black ink produced by the CMYK colours is not the strong black. So you need to add some black ink to get the best results for printing true black. If you would like to have a darker shade of any colour, you must add black in CMYK mode.

And what about the lighter shade of colours? Because white ink cannot be created using CMYK colours, you need to work under the hypothesis that you are printing colour on a white paper. As small dots of ink are used to print images the inks are used in lower percentage to produce lighter shades so that more white colour 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%. But when the total percentage does reach 400%, the ink will take more time to dry. Hence, the total percentage of ink should not be more than 300% in CMYK mode.

Both the colour modes have their own limitations. Images developed using RGB mode can’t be converted smoothly into CMYK mode due to the brightness of the RGB colours. Similarly, CMYK colours can’t be converted to 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.

What Country in the World has the Best Quality of Life?

While the question of which country has the best quality of life is often approached subjectively, a careful analysis of several factors is important to be able to wrap up which one is the leading objectively speaking. An objective approach would be to rate the superiority of life through the Human development index (HDI), which is an annual report, bear by the United Nations Development Fund.

According to the latest human development report by the United Nations, the country that has the lofty 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 confused 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 influence 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 crouched 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 well-heeledin 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 grand 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 confusion that Norway would remain on top even for the next years to come.

Tips to Creating a New Business Logo

A logo is a crucial step to creating a business. It is the face of your business. And like your face represents the tone of your business, indicates the service and screams the professionalism or lack there of.

People spend a lot of money on the formation of their logo and walk away with no artwork files. Then a couple months down the track when they need to put signage on their new building they cannot track the design studio down that created the original logo for them and so incur costs to have it recreated. This is redundant and may cause difficulties when trying to recreate 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 desired that if your service or product name is not in your business name then perhaps an icon will help in portraying 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 looking for a more illustrative finish without losing recognition.

A perfect example of this is the well-known and executed Nike logo.

Tip 2
Colour can be an crucial decision as it not only could alter the output costs but can also margin your output use. Think about the end result and what you will be assigning your branding onto in the future. Make sure your designer is aware of this as they should design accordingly.

Tip 3
Ensure you get a back up disk of your logo as a master file and make sure that it includes all the files required for the different printing formats.

Creative software updates frequently and some programmes become obsolete. Confirm 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 arrange. For example it is hard to 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
Make certain 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
readable

Tip 7
Confirm 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 acquire 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.
