About "CMYK" Colour Printing:
Ever wondered as to how Philatelic Printing Colour Processes work in stamps?
We often come across a term used in Technical Specifications in Philately - "Colours = Four Colours".
What are these four colours?
The most common method of colour printing is known as "CMYK", which is an acronym for the basic colors that, when combined, create the full range of hues.
Combining the correct amounts of "Cyan" (blue), "Magenta" (pink) and "Yellow" in the printing press makes it possible to achieve most of the colours needed to print stamps.
Theoretically, the colour black can be made by combining all three of these basic colors, but in order to achieve a clear and uniform shade of black, it is customary to print it as an additional colour, known by printers as "Key".
In exceptional cases, when a very specific hue is required, or when incorporating a metallic colour such as silver or gold, an additional colour will be utilised in the printing process, but most stamps are printed using only the four basic colours.
Before printing, during the “colour separation” stage, four printing plates are prepared, one for each of the colours.
The Special Sheet (SS), which features four stamps on the bottom row and three rows of labels (which are not postage stamps), represents the products of each of the printing plates and the intermediate products obtained as each colour is added on top of the last.
The top row of the sheet shows the products of each plate separately in order to demonstrate the process, but in reality, only the black label actually exists during the printing process (as it is the first colour printed).
Each of the following rows features the result after adding the second and third colours (cyan and magenta) and the row of stamps presents the result after the last colour (yellow) is added, completing the process.
Close attention is paid to the precise placement of the printing of each colour.
Numerous special printing marks are incorporated into the margins of the printing sheet to help printers ensure that the final image is sharp and clear.
The colourful Stamp of 16 NIS produced at the end of the printing process.
One of the key printing symbols, that looks like a coloured circle split into four, is featured in the special cancellation that was prepared for the CMYK Color Printing stamps.
The CMYK Colour Printing stamp sheet gives collectors a rare view of the stamp production process and serves as a glimpse into the world of the designers and printers who produce these beautiful stamps all over the word.
Chlorurus (Parrot Fish):
The Chlorurus is a colourful parrot fish that lives in the shallow sea, around coral reefs. This fish’s mouth is hard and shaped like a parrot’s beak.
The Chlorurus has hundreds of sharp teeth arranged in rows which it uses to bite the coral and eat the algae growing there.
Cleaning the algae from the coral helps the reef grow and prevents it from being covered in a layer of algae.
The fish’s bright colours fit in well with the background of the colourful coral and allow it to hide from predators.
