Gabdu 0 Posted November 23, 2011 Hello there, I was wondering if someone can help me: I'm making decals with the Oracal 638 Material. I will be using a plotter machine of someone I know. I don't know the name of the plotter, but I was wondering what pressure setting is best for this material? Does this depend on the machine or is there a standard unit of pressure that will work for the 638? Thanks, Gabdu Share this post Link to post Share on other sites
arty-rc 719 Posted November 23, 2011 Every cutter is different, even two identical machines will cut with different pressure settings. Different brands of vinyl will also cut differently. I would use the "test" mode to pick out the best pressure setting before cutting your graphic. I always do a test cut before cutting with different vinyl.
