Here is a VERY frequently asked question. And as a matter of fact it has a huge importance for the chosen effect of your lenticular piece.
The lens is like a little magnifying glass, so it shows what’s underneath, and your eyes are pretty close from one an other (less then 3″ apart), so when you [...]
Different “pitches”
Mechanical pitch: The exact physical count of lenticules per inch. Pitch value is measured in Lenticules Per Inch (LPI).
Visual pitch: the distance at which we have the best visual result.
Prototype pitch: determined from the visual pitch, is the pitch in which we must interlace the document to acquire an appropriate prototype.
Printing press pitch: determined [...]
Conventionnal offset printing (directly on the lens)
For medium to large print run and for small print format. Exceptionnal quality (resolution up to 800 lpi). Drying time from 3 to 5 day.
UV offset printing (directly on the lens)For large to really large print run. Good enough quality (resolution up to 200 lpi). Instant drying.
Ink jet printing [...]
Visual changes (flip)
Consist of visualising from 2 to 4 different images on the same lens.
Three dimensions (3D)
With a vertical lens, a 2D image is separate in multiple layers shifted from one an other. It gives a relief effect that makes a 3D illusion. The right eye sees an image while the left eye sees an [...]
The sequential assembly of images printed on a lens.
The lenticular lens is composed of multiple parallel lens strips with the same optical caracteristics. Each strip magnify and project a micro image strip printed on the back of the lenticular lens, in way that all strips can be sequentially seen for each vision angle of the [...]
Even before the beginning of the photographic techniques, scientists tried some interactions with images and lenses to produce 3 dimensional images. Some was succesfull, some not. In the late 20s, Herbert Ives simplifies the concept and used a lens array to produce the effect. The basic lenticular lens was invented.
That was a first step, but [...]
