Inkjet Printer Colours – How They Work Together
Inkjet Printer Colours How They Work Together
Most printing jobs are straightforward and whether you use unbranded, cheap inkjet cartridges or manufacturer compatible ink cartridges, the quality of printing should suffice for everyday home or office use.
However, there will be occasions when a higher level of colour mixing fidelity to the image you see on your PC screen will be required, so it's worth knowing a little of how printer ink cartridges work so you have a better idea when choosing your next set of replacements.
The basic principle to remember is that the way the colours of an image is delivered to your PC screen is very different to producing a colour image by inkjet on paper.
On your PC screen - the added colours you see projected and mixing together are based on the principle of RGB, which stands for Red, Green Blue.
On inkjet paper - the subtracted colours you see reflected on inkjet paper are based on the principle of CYM, which stands for Cyan( Green/Blue), Yellow and Magenta (Red).
On your PC screen - when light represented by each of the three colours (RGB) is added, the eye will see' any other intended colour, if the individual RGB colours are mixed in just the right proportions.
On inkjet paper - the material on the page absorbs part of the white light and only reflects back to the eye, the colours which have not been absorbed. Inkjet printers reproduce the principle by employing CYM, based on the three primary colours which subtract colour to create other colours.
Well known examples of colour subtraction is the addition of cyan and yellow to make green, and the mixing together of all three to create black or none at all to make white.
By printing millions of dots closely together, an optical illusion is created and the eye is fooled into thinking it is observing a continuous colour of different hue. A less saturated red could be made up from red dots with an increasing amount of white space in between them. The effect would fool the eye to seeing' this colour as pink.
According to the colour theory, black in is made up by mixing all three colours together. However, in practice it has been found that a far sharper image quality can be obtained by to just having black added as an additional colour.
This solution accounts for the now familiar printer ink cartridges we see today called CMYK, i.e. Cyan, Magenta, Yellow and Key (Black0, also used as the basis for 32-bit colour graphics in colour laser and solid ink printers.
Manufacturers also produce high quality ink jet printers which use half colour tones to give a professional print photograph, to match the latest high mega pixel camera image capture.
