Lentigram news

[Giovanni Remigi]

As you may know from previous posts I'm currently adding to Lentigram the capability to interlace multiple images on the same sheet. 

The engine works already pretty well as you can see in the following three simulations where I've interlaced 9 images. When you look in the front of each column, the images are perfectly aligned.

  

Unfortunately, for the alignment to work, I must provide two extra mandatory parameters, the interlacing distance and the lenticular sheet viewing angle. The first is easier to get. 

These parameters are used to estimate the mechanical pitch which is required for a correct alignment.

The angle of view is critical. If the angle is given with an error of 2 degrees, you will have a rotation of the side images by a corresponding angle roughly. So measuring correctly the angle of view is now critical.

I have some ideas, but I would like to know if any of you have some feedback, if you know any technique to measured the angle of view of a lenticular sheet which I could implement in Lentigram.

We can assume that optical pitch and interlacing distance can already be measured with high precision. We could measure the mechanical pitch but I would like to find an easier way.

Additionally, if any of you want to experiment with this new functionality, I would be happy to interlace the images for you as a two ways collaboration. There is no release available so you will have to sent me the sequence of images and all the parameters I will required.

Kind Regards,

Giovanni

Here you can see a screenshot of the first prototype of Lentigram professional. The generated lenticular sheet will be laminated and then cut into 9 pieces each of them correctly aligned.
