The PANTONE MATCHING SYSTEM (PMS), consist of swatch books that contain samples of hundreds of different colors, each identified with a code number and the formulation for each color.
In other words, the book tells exactly how much yellow and how much blue are required to make the specific color of yellowgreen ink the customer chose from the book.
Printers can obtain these books so they can order the exact color the customer wants.The printer may also use this book to mix ink colors in the plant.
The PANTONE MATCHING SYSTEM relys on ten basic colors (PMS black, PMS white, PMS rubine red, PMS rhodamine red, PMS warm red, PMS reflex blue, PMS process blue, PMS green,PMS purple and PMS yellow) which can be kept on hand and mixed using the roportions indicated in the PANTONE book to make the exact color desired.
Beside quantities of the basic colors listed above, the printer must also have an accurate scale to measure the quantities of ink required for the color, ink mixing knives, clean-up solvent, and rags.
To mix the inks, the exact amount of each required PMS basic color is measured out on the scale (use only PANTONE colors for acceptable results).
Then the basic colors are mixed together with the ink knives.
The ink is then tested for correct color and, if it is correct, it is placed in cans for use later or put directly into the press fountain.
Finally, the mess from mixing is cleaned up with solvent and rags.
Ink Teminology
VISCOSITY: is the resistance to flow. If ink flows or pours readily, it has a low viscosity. If it refuses to pour at all, it has a high viscosity.Offset inks usually have a relatively high viscosity.
LENGTH: Ink may be “long” or “short.” Test it by tapping a puddle of ink with a corner of an ink knife and lift the knife up. The ink will follow the knife and stretch into a string. The farther it stretches without breaking,the longer the ink. Offset inks are generally long.
TRANSPARENCY: refers to the opposite of opaque. A transparent ink does not hide the color beneath it, but mixes with it to create a third color. All inks used to print full color work must be transparent.
PERMANENT: Permanent inks maintain their color and do not fade even though exposed to sunlight for long periods. They are especially suited to signs and posters. Permanent inks are also called “fast” inks.
FUGITIVE: A fugitive ink is one that tends to lose its color and fade when exposed to long periods of sunlight.
RESISTANT: Resistant inks are made to withstand the action of gases, chemicals, heat, moisture, or scuffing.
LAKES: Lakes are body colors—not particularly strong or bright.
TONERS: Toners are strong colors—highly concentrated.
JOB BLACK: Job black is an ordinary, inexpensive, black ink used for most jobs.
HALFTONE BLACK: Halftone black ink is made especially made for printing the small dots in halftones.
METALLIC INKS:Metallic inks are made with metal powders. Bronze powder in an ink makes “gold.” Aluminum powder makes “silver” ink.
PROCESS INK COLORS: Process inks used to print full color work are: Process Yellow; Process Magenta (red); Process Cyan (blue); and Process Black.
