You could: Image – Mode – Greyscale and then Image – Mode – Bitmap –
[halftone screen]

Or you could take a better half-tone screen and make it a layer above the image, then change the Layer’s blending mode to Exclusion.
Play around with that. If you need a good, fine halftone screen let me know and I can put up a 1.5mb PSD file to download.

Thanks for the advices…

That was what I’m looking for…

I’ve to play around with that, on the default setting, it’s even worst than the photocopy itself, LOL

Great quick help! =)))

Print it at 300 dpi, it will Photocopy fine then.

I’ve a picture, a photoshop document, and I want print it on paper so I can photocopy it and it’s not that bad looking.

Is it possible to apply a texture to help the photocopier reproduce the picture in a better way?

A bit like in a newspaper, small and big dots, 66 dots per inch.

Yes, that’s exactly what you need to do. You need to print the image with a coarse halftone. Photocopy machines work well with halftones up to about 85 lines per inch.

You also need to make the image lighter; a photocopy machine has a great deal of dot gain, meaning it makes an image much, much darker.

First, lighten the image. Use Image->Adjust->Curves, and make the darkest part of the image no more than 85% printing. Reduce the midtone about another 15% on top of that. The image will look too light on your screen. That’s fine; the photocopy process will make it darker.

Then, print it with an 85 line halftone. If you have a PostScript laser printer, yo’re in luck; just use the Print command and set the halftone to 85 lines.

If you own a consumer-grade laser printer that is not PostScript, use Image->Mode->Bitmap. Set the output resolution to whatever your printer’s resolution is, use an 85-line elliptical dot halftone, and then print it.

If you have an inkjet printer, it’s tougher. Inkjet printers do not use a halftone and are quite poor at reproducing halftones. You can use Image->Mode->Bitmap, create your halftoned bitmap, and print it on an inkjet printer, but the results when you photocopy will not be as good as if you use a laser printer.

Alternately, if you have a photocopier with a "photo mode" setting, you can turn on the photocopier’s photo mode and photocopy an inkjet printout with no halftone. Again, the image will darken considerably, so lighten the image before you print it.

If the photocopy machine does not have a Photo mode, then the resolution the image is printed at has nothing to do with how well it copies. What is important is the *halftone screen* it is printed with.

Conventional photocopy machines have difficulty copying anything printed with a halftone over 85 lines or so.
