    Default finals and a halftone

    alright, well.. i dont have time to do a linocut before my finals (may 7th).. and ive done a lot of screen printing this semester, so i thought id try something new with it. ive been searching around for awhile about cmyk printing, but im really confused with what settings to enter when i alter my image to a bitmap.

    im using a 255 mesh screen and photoshop cs3.
    this is the image im using, minus the background (i cut out the main figure).
    i set my dpi to 600 and was playing around with lpis of 25-50. i wasnt sure what to put in for my angles though..
    im thinking about making the print about 6x7ish.

    i guess i dont really have a lot of time for trial and error, so i thought i could get some help here. n.n


    im not too crazy over this image, but it fits in for an "angle of view" project.. get it, myspace angle? ha? haha? myspace angles? funny!

    i was using this for a lot of reference:
    Full Color Screen Printing with Photoshop Screen Printing Information and Tutorials

    but hes using 63 lpi, and after browsing these boards apparently anything higher than 55 is unreasonable?

    ultimately, im just confused. ive been hearing a lot of different things and getting help from different people with different ideas.

    you can use a higher line screen than 55, but you need to have a good exposure setup and a high mesh screen. i've used up to 85 line screens and had no problems, but that was in a commercial shop, not my garage.

    i wouldn't use anything lower than 255

    your dpi, if you're making bitmap files for each screen, should be at least 600, but bitmaps are small files (especially for a 6x7) , so i'd go with 1200.

    in the silkscreen.com tutorial, he gives these angles:

    cyan = 75
    magenta = 15
    yellow = 105
    black = 45

    are you suggesting that i use any combination of the numbers you gave me for whichever layer (c, m, y, or k)? or..?

    i really appreciate you helping me, by the way.. if i had more time to experiment i probably wouldnt be bothering to ask questions that im sure youve answered countless of times.
    i dont have much to offer in exchange, but prince does:

    They recommended 15 degrees and 105 degrees for the same image? That doesn't make any sense for halftone. You're really only dealing with a range of zero to 90. In every halftone that I've worked with 15 and 105 might as well be the same angle.
