Question

Screen printing & controlling size of dot pattern in gradient halftones gradien

I'm using A Mac OS 10.6.8, and Illustrator CS5.

I do garment screen printing.

In my designs I use a gradient, which needs to have the halftone dots controlled, and a certain size, to expose properly on my screens to then print.

I can't seem to figure out how to adjust the frequency or LPI, and the angle so that they work. It still prints out as a seen on screen

Thanks ahaead of time for your reply.

You can only do this when printing the file.

If you need to set the resolution in the bojects, you might try the halftone effect in the plug-in Phantasm CS

Thanks to both.

Michael,

Doing it that way leaves the dots pixelated, not sharp enuff to expose to my screen.

Monika,

I did purchase and have used Astute Graphics Phantasm CS, and that is my work around.

In Freehand I could set the Frequency (LPI) to 32, and the Angle at 12 degrees, and I was done.

I sincerely wish Adobe would have or will, take the best of Freehand and put it into Illustrator. How would they know what the 'best' is? Ask their user community with messages posted in Subject: Freehand users. Then elaborate.

1 or 2 clicks in Freehand that take me 4 and up in Illustrator.

So as not to sour this, I do very much appreciate the prompt response from Adobe via Michael, and you Monika.

In Freehand I could....

Correct. FreeHand provides for object-level halftone settings; an invaluable feature for screen printing, flexography, sign printing, and more.

Illustrator merely provides for halftone control at the printing separation level.

Just one of many practical things which FreeHand has always done better than Illustrator.

Hi everybody,

I recently purchased Phantasm CS.

I am creating artwork using spot colors to be used for screen printing. I would like to use some of the colors at varying opacity levels, rather than use additional colors, the latter of which would increase the printing cost. I have read about lpi, but I'm not sure how the dpi setting within Phantasm will effect the final output. For example, when I create 4 different opacity levels of the same color, say 100%, 75%, 50% and 25%, as I increase the dpi the size of the halftone dots get smaller, which renders a more pleasant result on the screeen, but how will this efffect the printed version on the garment? Is this setting important or will the company printing the artwork override this setting when preparing the file for screen printing? As far as pattern is concerned, is regular or alternating better?

Thanks for whatever help you can provide. I'm just trying to understand the process the best I can before doing the artwork, I don't want to have to do it two or three times.

Thanks.

Mark

Did you try effect>pixelate>color halftone?
