I think I over expose the screen cause it came out way different but so far it looks good for my first try. Im gonna print out a exposure test to make sure it comes out good next time. Does anyone has a good free site where I could print it out from?


Resolution Input 240. Output 240
I use 156 mesh screen
42.5 line
22.5 degree angle
Round dot

Do I have to change my resolution? My images are high quality pictures. If I resize my image that is already bitmap with all the setting will that do anything bad to the picture?

Tomorrow im trying out doing cmyk with a 230 mesh screen. Any advice?

Here another sample. Same shirt.

Looks real good. I use a 305 mesh screen with 65 lpi.
I usually start with 300 dpi image output to 600 with 65 lpi / 22.5 angle / round dot.

if u want more crispy edges, try messin around in Illustrator wit live trace. always at least 300dpi

I always use elliptical dots, it helps to keep the outer edges of your design smoother. If a round dot lands right in the center area where the threads from the screen meets it will blow out the emulsion in that whole area - sounds like I'm being picky, but on a higher mesh with a higher lpi those things count.. looks good though..

What kind of light source are you using? And you really should work on getting the exposure time down. Check with some emulsion companies like Ulano and they'll probably send you a calculator free. Seems like there's a free download mentioned on this site also.

Advice? Work on the getting detail with the lower mesh counts before trying higher counts. The print looks OK but you lost quite a bit of detail when compared to the film.

As you move up to finer mesh and smaller dots, control is going to be more of an issue as will exposure and holding detail. 230 will likely be dyed (to minimize undercutting) so you'll have to adjust times. You'll have a tendency to press harder to get coverage and dot gain will increase.

No matter what, when you start losing the small dots, your subtle detail gets thrown out the window.

As far as exposure testing--you need a photographic film to attempt to do it properly--you want a stouffer test strip.

All in all not bad though. I've seen people wearing worse.

I use Casey's Paper Mill (Casey's Better Than Vellum) to print my positives on.
I still think your (is this your first?) halftone print came out great.
If it is your first, you have your head in the right place. Keep going!!!

I used to use elliptical dots a years ago, I don't know why I stopped. I'm going to try them again.
Thanks.....

The exposure unit I use

I print out the image on regular paper and added oil to it and use this type of emulsion

Na my first silk screen printing on a shirt. I use regular paper with oil.
