![]() ![]() A large number of those inks require you to thoroughly mix them and add additives (like low-bleed additives) into them to dilute them out and make them suitable for your project. In case you need, you can also spray adhesives – especially when you are printing on a heavier fabric like fleece that may require a specialty adhesive.Īlthough a lot of companies claim that their inks are print-ready, the reality is only a handful of them actually are fully print-ready. After ensuring that the pallets are all okay, the next thing to check for is adhesives that you use to keep the substrate in place. To avoid this problem, check and ensure that your pallets are not loose. In case your substrate is not stable and keeps moving while printing it may result in blurred edges and distort the entire image at times. Though mono-color prints can go well with lower tensions, screen tension below 20 Ne N/(inch)2 can cause issues with color blending in the case of multicolor prints. Ideally, screen tension should range between 20 N/(inch)2 and 25 N/(inch)2. However, without proper screen tension, the screen can sometimes ripple across the substrate that can smear ink, blur edges, and shift the surface of the substrate. Consider what kind of shirt you are working on and run a couple of tests on them – especially if your customer insists on a softer shirt.Įvery time your squeegee passes over the mesh, your screen should snap off the substrate completely to leave behind a crisp and clear print. To determine which substrates are at high risk of fibrillation, running a few test prints and the number of wash and dry cycles can be a good idea. To avoid fibrillation, formulate a strategy and adhere to it strictly. And the fibers in these super heavy garments are more prone to this effect. ![]() This has recently been a very critical issue since an increase in the demand for heavy-weight t-shirts. When they break through the ink layer, they cause the image to dull out or you can say ‘frost’ the final image. When these inks get washed, the lack of a heavy plastic coating causes some unprinted fibres to break. When there are prints involving transparent inks to use the whiteness of the shirt for certain bright hues this effect is more visible. >1/8 of an inch for thicker substrates like fleece.Įven if you set these off-contact distances but results are fuzzy consider adjusting the off-contact distance and performing a trial run of your screen printing.įibrillation often occurs more on light shirts. >1/16 of an inch for lighter substrates like t-shirts. In general, set the off-contact distances as below. Setting your press to have an adequate off-contact distance (tiny vertical space is left between the screen and the pallet below), ensures that there is enough room for the screen to rise up and away from the screen printing substrate. If you want to produce a crisp screen print, you should be able to snap the screen upward, that can facilitate the shearing of ink as the squeegee passes. The most common cause is uneven level of platens that results in a change in the critical off contact distance which leads to a visible shift in the hues. Several factors that determine the amount of ink flowing through a particular screen can disrupt these proportions. This is because proportional densities of the four process colors determine hues in this process. Sometimes, maintaining color density is difficult in halftone printing. So, let’s understand in detail those common problems and how you can resolve them. ![]() If you are a screen printer, ensure to handle those issues in a way that they don’t affect your productivity and business. However, there are some common screen printing issues that you may have to face as a screen-printer. Screen Printing has been a popular printing method as it is cost-effective, versatile, and provides long-lasting and high-quality outputs. ![]()
