A Good Halftone

[RichieGoodtimes]

And don't use that fucking halftone filter for halftoning for shirts. There are better ways.

Im on it, Right now i make some cool textures by simply airbrushing with black on white paper...scan it in (and convert it into an image with a transparent backround) and am able to use as backrounds etc...and when i comes to the press i can convert the color scheme to whatever...also can layer the textures...

I would actually prefer to have a greyscale file, cuz then I could select the black through select>color range>shadows and drag the info into another file. That way I have the halftome as a layer I can position over other info and get the effect of what it would look like printed over other shit. I'll have to try using channels. Saving as a bitmap seems to make good halftones, Charlie. I guess I can just save it back to greyscale.

yeah yeah, just save it back to grayscal after you bitmap it.. but watch your memory..

3 colour shirt on white, im talking about the black plate. And Im trying to keep as much detail in the image as i can. whats a better conversion method than the halftone filter?

Black Screen on a white shirt?
45lpi 82° or 55lpi 82°.
They're both adequate.
Leave the black screen as a greyscale channel. Under Print Options set these Frequencies and Angles and print out your film.
The problem with that halftone filter is that there's no way to take into account Moire on a shirt. You have to have control over the screen angle.

hey Richie, when you print four color process should you run an elliptical dot on yer film positives? instead of a round dot? you notice any difference?

[HYNES]

great. Finally, will this setting affect parts of the black plate I want to keep solid (ie text)?

[RichieGoodtimes]

We always run elipitical for everything. Way more moire and screen interference with any other dot shape.

To keep your text black without any fuzziness keep your dpi at 300 and threshld the text. 300 dpi is adequate for bitmap (theshold is pseudo bitmap) images for garment printing. Anything that is 100% black will print out at 100% black. Seperation setup won't change anything.
