Flip FX

The Flip effect replaces one entire image with another, or turns specific visual elements on and off.

The action occurs within the angular zone governed by the lenticular lens design -approx. 48 degrees of arc. A 2-Image Flip effect provides up to 24 degrees of arc “on” time per image, whilst a 3-Image Flip effect provides 16 angular degrees per image. 4-6 Image Flip effects are sometimes possible, but the “on” time per image becomes increasingly shorter, and each image perhaps less distinct.

The Flip effect is most commonly used to demonstrate different states of the same theme:

  • Old and New
  • Before and After
  • With and Without
  • Season 1 and Season 2
  • Day and Night
  • Cause and Effect
  • Colour 1 and Colour 2
  • Language 1 and Language 2

Flipping elements should:

  • be similar in shape, size, and position
  • be similar in colour & tone (i.e. avoid high contrast)
  • have the same or a similar background or use a similar colour palette
  • be confined to the middle 2/3's of the print (particularly for posters)
  • definitely not be positioned over a white, a pastel or plain colour background
  • not appear over a very dark background
  • generally avoid text changing in the same location

For best results:

  • hand-held pieces should preferentially flip top/bottom
  • use "busy" detailed, colourful or patterned backgrounds
  • consign copious text & information to the regular backside print
  • avoid white as it will be contaminated by colour in the other image/s
  • avoid white due to ghosting through it from the other image/s
  • avoid white as it can be contaminated by slight colour misregistration
  • avoid small italic text and diagonal lines due to "staircasing" by the lens
  • avoid small, fine text and lines as parts can break up under the lens
  • avoid Serif font styles as the narrow strokes and ticks can disappear
