But may not be to your expectation....
- Laser prints do not give even black on transparency (banding is visible)
- Laser prints turn up as greyish on transparency
- Laser prints have "specks" of no toner spots
You may have to touch up with a Marvey Marker

Thanks ykia,
Been doing research for producing zone plate, most site propose using high contrast negative to recopy it, but I thought those service already extinct, and don't want to buy a roll of neg and process it myself.
Only came across one site mention it workable on laserjet transparency.......:embrass:
guess now I have to try other way.

Isit 100% opaque?
If have, I will use them. Any contacts?
just joined in the thread halfway.. read something about catchlights want something opaque on a transparency?
I tried to do a 'mask' for PCB in the past. The PCB traces that I want had to be opaque and those I didn't want had to be transparent. I printed on a transparency with laserjet and photocopier machine. Both didn't turn out transparent. A technician told me there is a kind of specialised copier machine to do these that prints out the 'black' parts in high density make it more opaque than normal machines and queensway shopping centre didn't have it.
moral of my post: laserjet and normal zapping machine wun work
if got 100% opaque printing service i also interested for projects later down the road

That's right. PCB need 100% opaque film, those silk screen people also need 100% opaque film. How come I never thought of that, still think that already extinct.yanyewkay said:just joined in the thread halfway.. read something about catchlights want something opaque on a transparency?

best to use a vector format like freehand or illustratorcatchlights said:Thanks.

these are pin sharp not resolution dependant
can blow up to building size and still be sharp
but typically the films are actually for commercial printing
so it is very sharp and hi res
