Dimensioning a Paint Scheme with Hatch Marks

[banjax]

I have a part that will need to be painted with a pattern of hatchmarks. There will be 1/8" black stripes followed by 3/8" yellow stripes. In order to dimension this properly according to ANSI standards, would I need to count up all the stripes and say "28X .125 BLACK" or is this a situation where using the typical callout still applies ".125 BLACK TYP"?

Thanks

Check out forum1103, use of typ not being explicitly supported by the standards has been discussed many times - including in the last week or so.

Might be a case where you can get away with a note something like "ALTERNATING STRIPES .125+-.03 BLACK AND .375+-.03 WIDE YELLOW ON SURFACE INDICATED PAINT SHALL COMPLY WITH ...<insert color spec>

By the way, unless you're working to very old version of the standards they aren't direct ANSI and haven't been for a while so not many drafting folk hang out in this forum.
