Adjusting the optical pitch Perform this procedure: ● Once per substrate batch ● After Adjusting the substrate on page 12 This procedure measures the actual lens frequency and sets it in HumanEyes Producer3D. This enables HumanEyes Producer3D to compensate for frequency tolerances between substrate batches. 1. Use HumanEyes Producer3D to generate the pitch measurement job. 2. Print the pitch measurement job on a lenticular substrate. Figure 2-10 Pitch measurement job 3. To evaluate the pitch, tilt the lens. Using a high-magnification loupe, find a black line that goes all the way across the width of the substrate. 4. Enter the number of that black line into HumanEyes Producer3D. NOTE: For more information, see the HumanEyes Producer3D user guide. Aligning the center This procedure aligns the lens with interlaced image. Centering is critical for 3D effects. Animation effects should only appear when you look at the image from an angle, not when you look directly at the image. 14 Chapter 2 Procedures
