Screen set for lenticular printing

[Liviu]

Hello guys,

Have any idea about screen ruling and angle for lenticular printing?

Assuming an average job like:
Input:
- 16 images at 300 dpi
- Visual pitch 76.125 lens per inch
- Interlaced output tiff at 1218 by 1218 dpi

Output:
- CTP continuous variable resolution
- across the lens 2400 dpi
- along the lens 4872 dpi (4800 x 0.015% raster scale)

What ruling is recommended? I suppose angles should be group shifted to avoid alignment along lenses direction with yellow close to that direction.

Well, here's an interesting link on the subject:

METHOD FOR SCREENING COLOR SEPARATIONS OF A LENTICULAR IMAGE, COMPUTER PROGRAM PRODUCT AND METHOD FOR PRODUCING A LENTICULAR IMAGE ON A PRINTING MATERIAL

I would think that lenticular applications would be a great use of FM screening.

Thanks for link,

FM screen was my first choice but can not be generated using on different x and y resolution. I try on press 450 Lpi but colour shadows are limited.

why do you need "different x and y resolution"? And how do you plan to get it? I'm missing something.

Online I was reading of some other groups using FM screening for lenticular applications. Is there something unique in what you're attempting?

it is hard to know how to setting printer machine when you do 3d lenticular printing, but you can try more and do record, then know the best effect.
