I'm trying to create an image for photo-etching where I don't have to use a separate aquatint screen in my exposures. I created a 720 PPI randow dot bitmap image, increasing the blacks so they print as 'dots' with space around them (instead of solid black) but when I create this on my inkjet printer, it comes out looking very 'grainy,' even though I'm thinking that 720 is a pretty high output resolution. I'm wondering if I should try an even higher resolution, like 1440 or 2880?

I'm outputing to an Epson R2400 inkjet printer for this.

Best, David.

You may find my plugin RASTUS useful. Download a demo or ask me for a trial of the full version. It is far more effective than Photoshop's Diffusion Dither and provides a very pleasant pattern reminiscent of traditional screenless processes.

It is popular among alternative-process photographers.

Thanks Toby, I was hoping there was something like this out there, but I couldn't ever find it. A few questions:

* This is a plug-in correct?
* Does it work with Photoshop CS?
* Can I output to my Epson R2400?
* And since its a plug-in, can I use it with any file type I can open in Photoshop (e.g. PSD, TIF, JPEG)?

Best, David.
