LENTICULAR GLOSSARY

 

Alignment

The matching up of the image to the lines or lens.

Contrast

The tonal change in color from light to dark. High contrast images can create ghosting in an animated lenticular.

Cross Talk

In an animated lenticular, the intrusion of one frame into the viewing space of another causing a smear in the animation.

Cylinder

An engraved production roll for use in extruding lenticular lens sheet material.

Direct-to-lens

Printing of image is on the lens itself as opposed to printing on paper and then laminating paper to lens.

DPI

Dots per inch. A measure of the resolution of a printed image.

Dynamic Images

A specific lenticular process developed by Kodak. Division was closed but large format version still exists.

Flip

A lenticular effect that animated between two images.

Focal Plane

In a 3D image, the plane that appears to be most in focus with other planes appearing to be in front or behind it.

Frames

The individual images that when run in sequence, make up a lenticular animation.

Gauge

The thickness of a lenticular lens sheet. Usually noted in mils or point (thousandths of an inch). There is a correlation between the thickness of a lens and its quality.

Ghosting

In an animated lenticular, the intrusion of one frame into the viewing space of another causing a smear in the animation.

Hologram

A 3D image that is created using lasers. Although they are often confused with lenticular (because both can display depth), they are really two very different products.

Interlacing

The process of striping and arranging printed information to a given pitch to match a lenticular lens.

Lamination

The process of adhering a pre-printed media to the lens sheet. Not applicable in direct to lens process. However, printed lenticular is often laminated to another substrate to add opacity and to allow backside printing.

Large Format

Any lenticular bigger than 26″x 38″. Too big to run through a traditional press, these images are usually digitally printed and hand laminated.

Lens Sheet

a sheet of transparent plastic material that has been extruded, cast or embossed with an array of identical parallel lenses.

Lenticular

A specialized printing process that allows depth, motion or a little of each to be shown in a flat piece of plastic. The effect is created using lenticules in the plastic sheet that serve as a decoder for the image that is printed behind it

Lenticular Manufacturer

A specialized printing process that allows depth, motion or a little of each to be shown in a flat piece of plastic. The effect is created using lenticules in the plastic sheet that serve as a decoder for the image that is printed behind it

Lenticule

A single lens in a lenticular sheet.

LPI

Lenses (or lines) per inch. The smaller the lenses the more will fit within an inch. Smaller lenses allow for less breakup of detail. However, bigger lenses (lower LPI) allow for better delineation between frames.

Morph

A lenticular effect where one image appears to melt into another image. This is done by creating an animation where each frame is successively more like the final frame.

Motion

A lenticular effect that shows movement as the image is turned. This is achieved by using a series of frame that when run in sequence, appear to show movement. Exact same principle as a GIF file for the internet, a movie or a flip book.

Overruns

Or “overs” amount of product beyond actual client order that can be delivered (and charged), usually no more than 3-5%.

Parallax

In a 3D image, the phenomenon where objects in a scene seem to shift relative to one another as the angle of view is changed.

Phase

A discrete frame or channel of a lenticular image.

Photoshop

The most popular software for basic image manipulation.

POS

Point of Sale Display

Proof

A single copy of a lenticular image that is produced to obtain client’s approval. Usually produced digitally.

PSA Backing

Pressure Sensitive Adhesive. This allows the end user to peel off a liner to reveal a sticky back.

Radius

Degree of curvature.

Registration

The alignment of the printed image to lenticular sheet.

Source Art

The artwork provided by the client to the lenticular vendor.

Straight Cut

A method of cutting the image out of the sheet using a flat blade instead of a die.

Thickness

The thickness of a lenticular lens sheet. Usually noted in mils or point (thousandths of an inch). There is a correlation between the thickness of a lens and its quality.

Zoom

A lenticular animation effect that makes the object appear to be getting closer as it animates. Achieved by simply making the image larger in each frame.
