Red is .004, Black is .003 and Yellow is .004, from my experiences with Pioneer. It could be different from other latex suppliers. My only dealings are with Pioneer.

I've measured it in the past with a micrometer. Not all of the measurements that I read matched what the latex was supposed to be. Some were off as much as a couple thousandths.
