The image basically is text of a black background. The text has no fill so that the black shows through and has stroke applied to give the writing an outline.
Apparently when with the image either in jpg or psd the text does not have a defined edge so that it tries to make the writing appear smoother on the background. When using for the t shirts the edge will be all sloppy and will not look good to the eye.
I am not worried about making the image again or converting the existing image. If i start again is there a way to turn anti-alias (on text) off before i start.
Thanks
