Working with Lenticulars

Hi All,

BTW, who is this quote from?

>>>>>>>>>>> I have had similar difficulty getting Sean McDonald to answer any questions about his product other than supplying a price list. That is poor salesmanship but they probably cater only to large industrials. I don't think they do any printing at all. I offered to forward his updated information to the 3D Suppliers list since it only has the company name and nothing else. He didn't respond. Perhaps he did the task himself? 

I found a URL on the web which details how to go about using a lenticular screen with computer generated images. It requires a very high resolution printing device but with experimentation you may be able to get it to work. 

The problem comes down to which of the products on the lenticular list most closely matches the actual resolution of your printing devices or computer screen. It seems each of the products has a different range of characteristics. Sean's usage description is helpful at the top but the list itself says the same thing about each product making it a very contradictory bit of information. They could use some marketing help, it seems... The URL relating to lenticulars is:

The lenticular printing machines used with photos use an optical/mechanical system to quickly expose strip by strip of the images into the final print. Since that's usually an emulsion directly on the lenticular, that's hard to duplicate in your "kitchen sink". You may be able to rig a mechanical device to use in a home darkroom. If anyone does experiment with this I for one would be interested in hearing about the results. Such an experiment would have to mechanically position each exposure strip on a piece of film at the same spacing of the lenticules in the material you have on hand. After exposing and developing the image you would carefully align the multi-strip image with the lenticular and glue it.

A computer seems to be the easiest way to "cut" the small strips by hand and reassemble them. It would be painstaking but could be worth it with the right image.

There's other information relating to lenticulars on the web if you do some searching.

Good Luck,

Larry Berlin
