    Default Index color seperation

    Hello..

    I am trying to figure out how to do an index color seperation. Well I have done it but the dot or squires seems so tiny that it just washes away...

    Is there a specific mesh size i should be using? Someone told me about some ration but I could not figure it out..

    Any suggestion would be appreciated..

    thanks

    2dpi to 3mesh, roughly. but you need to have an IDEAL exposure setup to pull off that burn.

    I did a bunch a while back, after a lot of testing we used 187 ppi on 305 mesh. Avoid a frequency count (ppi or dpi) that divides evenly into the mesh count (150 into 300)

    that's a pretty fine dot, you need to be using a high solids emulsion, vacuum frame, and backlit booth to develop it. Good film helps a lot too.

    if you are going to get into this, I would suggest making a tesat sheet with different size dots, burn them all print them, and see which combo works for you. You don't have my gear and I don't have yours, so you have to figure out what you can do with what you've got. Run what ya brung, as they say.
