You can try using lower mesh counts or do multiple print strokes on high mesh counts to increase opacity. As the ink layer gets thicker, the less light can shine through. The higher the mesh count, the thinner the ink deposit and the lower the mesh count, the thicker ink deposit. Mesh count will also have an effect on an ink's opacity.The color will still shift lighter on a base white, but when you print, it will be closer to the color you were originally aiming for. When mixing Pantone colors, you can choose the Pantone color a shade darker in your Pantone book to make the color a little richer in saturation.Keep in mind that you will have to choose which tip is right for the job at hand and the inks you’re using. Here are some ways you can start to correct for color shifts. The more you test, the less time you'll need to correct the colors. The more that you understand how the natural opacity of the inks you use, the better you will get at making educated guesses on how to adjust. Every brand of ink, every ink line within those brands, and every color within those ink lines will have different natural opacities. The unfortunate part is that there is no cut-and-dry way to make color adjustments. Now that you have an understanding of how ink's opacity affects color shift, how can you use this information to make adjustments before you get on press? Printing colors on a base white versus a black shirt causes major color shifts. The ink's opacity is the main factor at play when it comes to how much ink will color shift on press. All inks will have some degree of natural opacity. The more black and white inside the ink, less light will be able to travel through because it is either being reflected by the white or absorbed by the black. White reflects light and black absorbs light. Even with the base white and black, there is still some color shift, but it is much less than colors like navy. However, colors like fuchsia and light blue have a higher natural opacity. Choosing a low opacity color like magenta to be in the design means you'll have to work a lot harder to make sure it comes out looking the way you want it to. But in this case, it makes the ink color appear darker. The black shirt is being seen through the ink just like the base white. If you print low opacity colors directly on a black shirt, the color becomes more difficult to see. Magenta reflected off a base white (left) is much lighter than magenta printed directly on the t-shirt (right). Light is moving through the magenta, hitting the white underneath, bouncing off of that base white, and back to your eyes making it appear lighter than the control print. This is because the base white is being seen through the low-opacity inks. When you print inks that are more translucent on a base white, the color will become lighter than the bucket. Printing directly on a white t-shirt gives you the most accurate color to the bucket, so it makes for a great control print.Ĭolors like magenta and navy are more translucent, so they are strongly influenced by the base white and the color of the shirt underneath the ink. Half of the print is printed on an underbase, and the other half isn’t, meaning the ink is printed directly on the shirt as a side-by-side comparison. To show you visually what colorshift looks like for you, ink expert Colin Huggins prints the classic line of FN-INK™ colors on two shirts: one black and one white. This can make the translucent ink appear darker or lighter because its color is influenced by the T-shirt underneath.Ĭolor shift is entirely due to the natural opacity of the inks you use and the kinds of garments you are printing those inks on. The less opaque-or translucent- something is, the more light will travel through the object, hit whatever is behind it (in this case, a T-shirt), and reflect back. The water bottle is translucent, meaning you can see the bucket of ink through the bottle. Light will only reflect and absorb off its surface. The white lid on a bucket of ink, for example, is considered opaque because no light is able to move through it. If something is 100% opaque, then you will not be able to see through it at all. Opacity is how well light can travel through an object. Let's look at the different variables at play and show you how to make adjustments to deal with color shift both before you print and on press. Depending on a few key factors, you can end up with one color looking completely different than you anticipated. Have you ever printed a color, checked the print, and noticed it turned out different than you expected? That is called color shift.
