    Limit number of colors used

    Steph Rowe

      Hi everyone,


      I have created a design for a t-shirt competition. I have not read till now that you are only allowed to use a maximum of 8 colours in you design!!
      Trouble is that I do not know how many colours I have actually used :/
      I have read blogs on how to convert the colours by saving the file as a giff as well as posterising which all seem to make my work look like a waste of time...
      I have attached the image and if anyone has any ideas at all as to how I should go about this they would all be greatly appreciated!!


      Thanks again!

          does this loose too much for you?

            a) GIF or PNG with manually selected palette and dithering.

            In my opinion one shouldn't use dithering for printing on textile.


            b) Make palette manually in Photoshop (black, white, green, blue,

            darkbrown, lightbrown) by picking typical colors.

            Save as racoon.ase for exchange.

            Apply Live trace in Illustrator, using this palette,

            Result is a vector graphic - better suited for textile than a

            dithered raster graphic.


            An example, not optimized.

              8 colors indicates textile silk screen or flexo printing where each color is applied separately and they don't mix other than creating the illusion with dithering/ halftone dots. That being so, it probably means you have indeed wasted your time. Such stuff will usually have to be doen in Illustrator or similar programs because the vector contours are required for the masks. At this point your best bet is to take your image and rebuild it using Live Trace/ the tracing tool in AI....

                possibly losing a bit much detail but you've done a far better job at enhancing this than what i did!! Silkrooster: Did you just play around with the eyedropper tool in Photoshop and then select 8 colors or did you achieve this result a different way? Thank you very much for your speedy response!

                  Thank you very much for your explanation Gernot! When you say 'choose typical colors' do you mean generic colors such as primary reds and blues or those that are typical within the image I submitted earlier? I think this could be a far more user-friendly way of submitting my idea. It's stil not ideal but i suppose I'll know for the future to hold back with the color!

                    by typical colors I mean those which are typical within

                    the original image and which you want to see in the

                    vector graphic as well.

                    I had also used green, just to show that these small

                    green patches are not ignored then.
