I've been screenprinting for about a year now and I'm just now trying to complete a project for the first time with halftones. I'm trying to print an image that an artist friend of mine drew with a pencil. I was able to convert the image to halftones using PS bitmap feature and want to print it in black.
My output is set to 300dpi, frequency 20, angle 0, and shape is round. The image printed up really well and I'm pretty confident it'll turn out if I get everything else right.
My question, and please don't use terms like "moire" and "cross linked" because it will just further confuse me! I'm using a halogen (no vacuum blanket) for exposure with black foam underneath and weight on top. I have screens that are 110, 156, and 200. Does the exposure time change for halftones and which screen mesh should I use? I'm guessing 110 is too low.
Here's the original image before I converted it.
