I just got my $50.00 back in knowlege. Thanks A simple trick that will work great on business cards and letterheads. Do you think that this effect could be pulled off on a t-shirt with one or two colors screenprinted?

Really nice Doug! Thanks. So if you wanted to use this effect in a screenprint how does it come across. I'm thinking that some method of doing the fades that had the line widths tapering out to nothing where you wanted them to fade would work better for that application. How would you do that? Robin, do you see where I am headed?

Yep it works in screenprinting- you have control over how big the lines are when you draw them.
Kelly- the simpiliest way I have found to get the tapered lines is to print the halftones out in "postscript" using "line" as halftone type, set the angle to 0 or 90 degrees (whichever suits your look) and then bump the line screen down to a low number to make the lines larger.
Hopefully that makes sense

I'm not sure I understand, halftones are pretty new to me, though I need to get them figured in order to use my photoresist stencils to full capacity. Is there a halftones for dummies book? Are we both talking the same type of fade for starters. I'm looking for this effect. Sorry it is small - but each line tapers to a point.

Kelly- half tones aren't any foreign language, but take a bit of getting used to when you're not familiar with them.
Newspapers can print only solid colour, 100% or nothing, zero%. Grey is not an option like it is in an inkjet printer or on a photo. Screen printing is similar- you can lay down colour, or no colour that's it.
For solid text etc that's fine. If you would like a photo, or a fade through shades of grey, the picture needs to be reduced to solid dots of varying sizes with varying amounts of white space around them. That's how you percieve greys & photos in newspapers.
These dots are called half tones- as the effect is a tone of say half intensity of balck- or something like that.
Ideally you need a post script driver for your printer, which is ideally a laser printer. The driver gives you the option of setting the line screen angle, dot size/frequency, dot shape (square, circular, elliptical, diamond or custom shape,etc). Then the printer driver generates a file where a photo with greys is turned into a halftone picture with varying sizes of 100% black dots to give you light & dark greys etc.
There are other ways of getting there too, but they're a bit harder to learn & don't give as much control as a Postsrcipt printer driver.
(Ghostscript is one option, if you only have an inkjet printer & want to output halftones- but it takes a bit of learning...be warned!)
There are halftone filter/render settings (or something) in Photoshop, but they're a bit limited...
Hope that helps!
edit to add- Good post, Doug- thanks!
