IMAGE FILE REQUIRMENTS
Files can be provided as layered PhotoShop files or as vector graphic
files such as Illustrator. Should the file size exceed the limits of the
storage media, separate files can be provided, but must be of the
same resolution and dimensions. Files must not be flattened and
must include alpha channels or clipping paths to allow for
re-composition of individual elements. Vector graphic files must be
capable of being ungrouped to allow extraction of individual elements.
See illustration.

TYPE
Include all fonts associated with the project. Include vector graphic
files of the type. Be sure to create outlines or paths for all type three
(3 or III) fonts. this will ensure no delays should there be conflicts or
corruption in fonts provided.
Preferable vector format is Adobe Illustrator. If possible, avoid Quark
Xpress documents as quark often utilizes proxies (low-resolution
copies) of images and does not allow exporting type with outlines or
paths. Quark files can incur extra creative costs if conversion to a
suitable format is necessary.

LIMITED ANIMATION
Provide client approved CMYK files. This will avoid a second interlacing
charge for mastering unapproved art due to composition, typos,
incorrect color, etc.
Include standard 3mm (1/8") bleed and image safe areas.
Bitmap and/or scanned art should be of sufficient resolution for
acceptable reproduction, typically 300 dpi or more.
Art can be supplied as a single layered file which will ensure proper
alignment and registration between phases. Art can also be supplied
as separate files, however, individual frame files should be of the
same resolution and dimensions to avoid inter-frame mis-register.

FULL MOTION VIDEO OR ANIMATION
Full motion animation footage can be captured from a variety of
sources including motion picture film, video, stop motion photography,
time lapse photography, computer generated graphic's and HD
footage. However, several rules of thumb should be observed when
selecting footage for your project.
Resolution of source material vs. final reproduction size
VHS video typically has a horizontal resolution of less than 425 lines,
digital Beta has typically 525 lines of horizontal resolution, while digital
motion picture files can have as much as 4,000 lines of resolution.
Bearing these resolutions in mind, digitized motion picture film can
obviously be enlarged to much larger dimensions than VHS or Beta
before pixilation or artifacts become visibly apparent.
Aspect ration of source footage vs. aspect ratio of final image
Final image dimensions must fit within the aspect ratio of the source
footage. This directly affects point 1 in this section.
An example can be taken from a business card produced from video source footage.
Video maintains a 4:3 aspect ratio while a business card typically
trims at 50.8 mm x 76.2 mm (2" x 3") (vertical portrait format) or at
76.2 mm x 50.8 mm (3" x 2") (horizontal landscape format) for aspect
ratios of 5:7 and 7:5 respectively.
In this case, one can observe in
illustration 4 that figure 4b encompasses more of the video image
than figure 4a - and can be enlarged correspondingly larger than
figure 4a (refer to Resolution of source material above) as more pixel
data is included in the image.

MOVEMENT WITHIN A SCENE
Extreme movement of camera and/or subject within the scene can
result in a confusing final image.
When the camera pans, dollies or trucks with the subject in a manner
such that the subject maintains a relatively stationary position within
the composition or frame.
Aspect ratio of the final image allows enough top to bottom or side to
side room to re-register the individual frames such as that the subject
maintains a relatively stationary position within the composition.
Unfortunately, this decreases the amount of usable image data and
limits the amount of enlargement that can be performed before pixilation
becomes visibly apparent.

PREPARING 3-D FILES
Conventional graphics can easily be converted to effectively display
the illusion of depth when certain points are followed during art preparation.
?The lenticules MUST run vertically (top to bottom) to achieve the illusion
of depth. Remember this point when calculating a per sheet yield
?Backgrounds must be wider than the final image to account for parallax
(See the illustration below). Example: if the unit final size is 203
x 254 mm (8"x10") the background should be 210 x 254 mm
(8.25"x10"). A general scale to follow is:
Up to: 203 x 254 mm add 7 mm (8"x10" add .25")
304 x 406. add 13 mm (12"x16' add .5')
609. x 609 add 25 mm (24"x24" add 1")
This scale can be followed fairly loosely. If you are unsure of how
much extra to include, remember that more is better as photo retouch
work or cloning can incur additional creative costs.
If possible,backgrounds should avoid solid colors or horizontal stripes.
These two situations do not provide a depth reference to the observer.
An alternative to a solid color would be to add texture such as
crumpled paper to the color.
if objects are cut out of the background to be layered with the background,
the removed area of the background must be cloned or
retouched to cover the void area.
Elements that are supposed to project forward of the aim-point or surface
should not be encroached or bleed beyond the trim. If the element
is trimmed, confusing depth cues will be observed and the illusion
of dimension on that element will be lost.
Element that overlap even slightly are good depth cues and will
enhance the illusion of depth.
Forcing perspectives can enhance the illusion of depth. An example
of forced perspective is where objects appear to get smaller the farther
they are from the observer.
Psychologically, cooler colors tend to recede and warmer colors tend
to project.
Logos or important type and copy should be composed to be on or
near the aim-point.
The same rules for type, resolution and client approval apply.

EXTRUDED LENS PROCESS
We print on the back of the lens, reverse image (wrong reading).
Available lens 75 line .450 mm ( .0185) APET: good for pieces viewed from a
shorter distance (handheld). Will hold limited animation, up to 12 frames.
60 line .508 mm (.020? APET: good for pieces viewed from a
short (handheld) to medium distance, will hold animation well, up to
16 frames. Maxium image size A2, (20?x 28?.
Must have a sheet laminated or mounted to the back to have copy on
two sides.

PRINTING RESTRICTIONS
The wider the sheet, the greater chance for distortion.
Must know which way image lines go - vertical or horizontal -
for pricing and layout purposes.
for proper registration of the image to the lens, we must extrude the
lens before doing the mastering (interleaving).
Delivery of material is normally 2-3 weeks, but should be confirmed.

3-D LENTICULAR
There is a dimensional effect because each eye looks at a different
image.There are at least 12 images in 3D. Interlacing determines how many.
Lens HAS to run vertically. If you turn the image horizontal, the 3D
effect goes away. The thicker the lens, the greater the depth perception.

ANIMATION LENTICULAR
Must run lines horizontally.
Otherwise images are fuzzy.
On vertical animation you may see more than one image at the same time.
However, a POP has to be vertical, which means full animation is not good for POP.
Limited Animation is OK for POP. Otherwise animation should be sized for handheld pieces
like phone cards.
Distance is important for viewing. Must know how far away image is
going to be viewed BEFORE interlacing is started.
Animation must start our with video films or equivalent to get the next
frame movement. Computer generated art is also good.
Videos MUST be at least BETA-S or BETA-SP.
Videos MUST be from a professional photographer, NO VHS!!
35 MM Movie film is great.
Not all sequences are candidates for animation.
DON'T have movement that goes from one side of the card to the
other. For example: Michael Jordon running down the court. Michael
Jordon dunking the ball at the basket is much better.
DON'T try to make the animation overly complex.
- Back to Top - |
FLIP LENTICULAR
Flip is normally two totally different images flipping from one image to
the other.
Animation in contrast is a series of frames with small incremental
moves to create full flow.
Flip art is normally two separate files.
DON'T use a white background as it is more likely to ghost.

GLOSSARY OF TERMS
Aimpoint: The dimensional plane that coincides with the surface of
the printed unit. Important elements, such as type or logos should be
composed for this plane.
Bitmap Image Also raster image: An arrangement of small squares
(pixels) used to define an image.
DPI Dots per inch: Defines resolution of bitmap images.
Interlace The process of combining image data from two or more
graphics in a configuration compatible with a lenticular lens array.
Lenticule: A single lens element in a lenticular lens array
characterized by curvature along one axis only.
Parallax: The apparent shift in objects/elements between right and
left perspective views. The greater the parallax shift the greater the
apparent depth
