I have made several shirts using a print from a particular company. This print has gold metalic ink that doesn't fully release. I've adjusted pressure but not the tempature which is set for 390 degrees. I've made another shirt using a print from another company that has silver metalic ink. I've used the same setting as with the other print and it release completely. Any Idea why this is happening and is there anything I can do to fix the promblem?
