Loved the video. I understand halftones a little better now. Glad I came across your video. Thank you for the knowledge. 🙌

Thanks a lot for your video, it helped me to understand more how to start half tones in Illustrator and refine it in photoshop. I'm pressing the bell so I can know when you have a new video.

Hi, nice tutorial, is it possible to upload the half tone sheet that you show in that video ? Can be useful to show to people when they ask questions about halftones and how much detail they want ! Thanks :)

[@AshleyTaylorUCF]

Sure! I can add it to the video.

I am very new to screen printing, so what do you do after you create the files do you print them on a printer on transparencies all three of them and then you make three different screens and can you just layer it in alignment with the registration?

Hi! Great video!
However, with the halftone sheet, there’s the 10% - 100% values. Are the values meant for opacity? If not, how do you control the pattern of the halftones?

[@AshleyTaylorUCF]

Hello Bryan the halftones are generated based on the value of the black as well as the dot size and angle in the Bitmap settings.

What resolution did you use for the first halftone file?

[@AshleyTaylorUCF]

300 dpi

Nice video. I am new at screen printing half tones. I have an image on 160 mesh that some of the fine detail did not come out. Is there a way to tell if the dots are too small or the screen was overexposed? Thanx for the info. I use paint shop pro to process images.

[@AshleyTaylorUCF]

Hello Bob, Yes, there is a formula Formula #1: Dot Size x 4 or 4.5= Mesh Count, so for example, if you have an 50 LPI size halftone x 4 = 200, so your screen mesh count would need to be 200. In your case, you know your mesh count so do the opposite, Formula #2: Mesh Count/ 4 or 4.5= LPI,
160 / 4 = 40 LPI so your dot size should not exceed 40LPI

@@AshleyTaylorUCF Thanx for the info. I use Printshop Pro to create the halftones. there is no reference to LPI unless it is called something else in PSP. Do you know if there is another way to calculate the correct size?
