Colour Printing - for Educational & Cartridge Test Purposes
Colour printers use YCMK [yellow, cyan, magenta & black]
Some use TWO cartridges [black & tri-colour]
With a tri-colour cartridge, the loss of any colour requires the replacement of the colour cartridge - i.e. ALL colours Yellow, Cyan & Magenta, even though TWO of the ink colours may still be adequate in level.
With FOUR cartridges YCMK a single ink cartridge can be replaced.
The following pages are useful for educational purposes AND for ink level test purposes. When your printer displays a 'low ink level' warning, as you are probably aware, the printing can continue ok for a considerable time.
Print cartridges are expensive and the following test pages will show when a cartridge definitely requires replacing - thus saving costs.
The Example shows the effects on printing when the Cyan ink level is VERY low and the cartridge DEFINITELY requires replacing. Note
