Screen printing on black and dark garments requires bright colors and needs an underlaying cured ink to keep the garment from influencing the brightnerss of the colors. Typically this is done with white ink as it is the brightest. However, it is also the largest pigment and thus the thickest ink.
We see this question a lot...... I want to create artwork or a drawing for imaging onto t-shirts, apparel or other clothing items, Where do I start? I also see a lot of Fluff articles and answers talking about "thinking of the message you want to convey & typography. But that is for corporate advertising campaign shirts and not a common person just wanting cool artwork or custom image on say a hoodie. If you are wanting to get your art on a garment these are the questions you need to answer and the things you will need to know........ First off, it is my experience that most people asking this are going to attempt to do the art, Illustration or graphic on a personal computer. This is because most people know that the graphics and reproduction Industry has probably experienced the greatest advances from the use of computers. So let me start by saying that you can do the art or design however you want. Be it drawing or painting on paper and canvas or sketching on wood.... all of this can be scanned into a digital file format.
