printing fine encoders (>300 lpi)

printing fine encoders (>300 lpi)

printing fine encoders (>300 lpi)

I have to find a way to print some encoder wheels with very fine resolution. Encoder (Avago AEDR-871x) is picky, and reads in neighborhood of 300 LPI --> one line is 1/600 inch (1/24 of a mm for those dwelling in civilised places).

I have a couple vector files to test print. Going to get some better paper and mylar and also try some print boutiques.

Anyone have experience with similar?

RE: printing fine encoders (>300 lpi)

You may have better luck doing it with conventional photochemistry (i.e. using photo reduction to expose film/photo paper)? Best laser prints I know of only get up to 1200 dpi, so a 1/600 line may not resolve.

Try U.S. Digital. They printed a mylar encoder disc for me with 3600 tracks on an 81mm diameter. I have notes on my specification about Avago being a renamed Agilent division, which is a renamed Hewlett Packard division. I cannot remember why I noted this.

US Digital. They have an OTS 2" disk with 2500 ticks, so by my calculations that's about 800 lpi.

Thanks, all!
