For those that want to have full control of the colours in the printed image please have a look at our machines sRGB colour profile.


Converting to a colour profile in Photoshop
To convert to a colour profile click "Edit" and then select "Convert to Profile". Make sure you have the appropriate profile selected in "Destination Space". Depending on the type of paper you have chosen for your album you will have a different colour profile.


RGB Colour Mode
RGB is the colour scheme that is associated with electronic displays, such as CRT, LCD monitors, digital cameras, and scanners. It is an additive type of colour mode, that combines the primary colours, red, green and blue, in various degrees to create a variety of different colours. When all three of the colours are combined and displayed to their full extent, the result is a pure white. When all three colours are combined to the lowest degree or value, the result is black. Software such as photo editing programs use the RGB colour mode because it offers the widest range of colours.


CMYK Colour Mode
Printers print colour onto paper using the CMYK colour mode only. This is a four colour mode that utilises the colours cyan, magenta, yellow and black in various amounts to create all of the necessary colours when printing images. It is a subtractive process, which means that each additional unique colour means more light is removed or absorbed, to create colours. When the first three colours are added together, the result is not pure black, but rather a very dark brown. The K colour, or black, is used to completely remove the light from the printed picture, which is why the eye perceives the colour as black.


Differences between RGB and CMYK Colour Modes
When a user generates graphics on a computer for printing or wishes to print images from a digital camera, it is a common mistake to assume that the colours seen on the screen will look the same in print. As a result of this mistake, files for printing are often erroneously sent in the Red-Green-Blue (RGB) format for printing. The issue lies in the fact that the computer screen and many photo editing programs show colours in RGB mode, while images are printed on paper in Cyan-Magenta-Yellow-Black (CMYK) format. Sometimes the conversion from RGB to CMYK works without any problems arising, and a printout will look identical to what shows up on the computer. In other cases, there will be noticeable differences between the shades of colour. The key to avoiding this potential problem is to convert all graphics to CMYK format during the layout design phase.
