Many people know of the conventional, CMYK, Hi-Fi, and Pantone spot colors but not many people are aware of other options available with effects pigments. Well, Anderberg is here to enlighten your printing world! Here is a basic run down of the most popular effects ink pigments.
Photochromic inks: These inks change from clear when indoors to color when outdoors (exposed to UV light). When the light source is removed, the color change is instantaneous and returns to it’s original color or becomes colorless.
Photochromic behavior can either be reversible or irreversible. You can print shorter run lengths but get more results with special effects.
For example there are some nail varnishes that you may have seen that change color when exposed to the sunlight. (Wet / dry offset, flexo, screen printing).
Thermochromic inks: These Inks are temperature activated. When these inks are exposed to different temperature such as when they are rubbed or held in a warm hand; they change their hues in response to the temperature fluctuations.
The once popular MoodRing is an example of this. Remember when you would press your warm finger to the ring and it would change colors? That is an example of thermochromic. We can print by offset, UV offset, and screen printing.
Photochromic and Thermochromic inks are both available in colorless-to-color and color-to-color formulations.
Hydrochromic: This kind of ink is similar to the above ones listed except it is activated by water, not sunlight or heat. Hydrochromic ink looks like white ink. The ink disappears when water touches it and the image behind it appears and when the ink dries, the image disappears.
There are some umbrella patterns made with hydrochromic ink.
UV Fluorescent: You guessed it! This kind of ink is invisible but turns fluorescent when exposed to UV light. These inks are often used in banknote printing. (Gravure, Offset, Vinyl Inks).
Optically Variable Ink:
When viewing this ink from different angles, it transforms from one color to another vividly. This ink is made up of minute flakes of metallic film and is very expensive therefore it is usually only printed in small areas.
Bleeding: This ink prints black but when exposed to any kind of water solution, it produces a red stain.
Fugitive Ink (water based): Similar to Bleeding ink, when exposed to water or an aqueous solution, the ink runs.
Coin Reactive: The image is only revealed when a coin is rubbed over the white or transparent ink.
Erasable: This kind of ink is usually used on the background of a document. When an eraser is rubbed on it, the ink will start to come off in that area.
Iridescent: When viewed at different angles, there is a change of iridescent hues.
Metameric Pairs: Two inks that appear to be the same color under one set of lights but are completely different colors under another set.
Puff Ink: When exposed to heat, this kind of ink rises and expands.
Glow in the Dark Ink: This one is self-explanatory. This ink glows in the dark after being exposed to a bright light and then placed in the dark.
Penetrating Ink: This kind of ink is usually used on the Arabic and MICR numbering of negotiable documents to prevent forgers from attempting to scrape off the number from the document. It contains a vivid red dye that goes into the fibers of the paper and will reveal itself through the back of the document.
