So if there is more emulsion then the exposure time will be slightly more for a 110 then a 305.Ģ.
Lower mesh screens have bigger mesh openings- they hold more emulsion- the exposure time will be longer then higher mesh screens. Using a 110 mesh screen will hold more emulsion in the screen mesh then a 305 mesh screen will hold. Here are some tips to help dial in your correct exposure times.ģ Variables that Will Affect Your Screen Exposure Time.ġ. Most new screen printers don't understand the different variables that change the amount of time a screen should be exposed. Through experience and experimentation with using different screen densities, you’ll find which screens give you the results you want when dealing with different types of projects.Exposing a screen and finding the proper exposure times can be a frustrating experience without the correct knowledge. While there are guidelines for which screen mesh counts are best suited to which jobs, the decision of which mesh count to use ultimately lies with you. To combine that, you might want to add a retarder to your water-based ink to keep the ink transferring and your job moving. That means that when you’re using a lower mesh count screen, you’ll have to expose your screens longer to allow the emulsion to properly set.Īlso, if you’re printing with water-based inks, the ink will dry out faster on finer screens. First, screens of different densities will hold varying amounts of emulsion, with lower mesh counts holding more. When you’re experimenting with different mesh counts in your screen printing, there are some other considerations to bear in mind. Other Considerations When Choosing a Screen Mesh Count 230 to 280 mesh count screens will deliver detailed prints with a softer hand feel however, because they allow for lighter ink deposits, prints created with these fine screens won’t be as bright or vivid.180 to 200 mesh counts are perfect for printing somewhat detailed images in light inks on dark fabrics.At the higher end of the mesh count spectrum, you can print a more detailed image while maintaining a fair ink deposit. Screens on the lower end of the mesh count spectrum put down heavier ink deposits and are ideal for printing underbases or printing bold colors on dark fabrics. 110 to 160 mesh count screens are the most versatile and the most commonly used in screen printing.80 to 86 mesh count is often used when making heat transfers, printing heavy underbases and when using some specialty inks, such as puff ink.It’s often used for block numbers and letters on athletic jerseys 60 mesh count allows for a heavy ink deposit.25 to 40 mesh count screens are ideal for glitter or shimmer inks, as these inks contain particles that can’t pass through finer mesh.Lower mesh count screens have larger openings that allow more ink to flow through, while higher mesh count screens allow for finer details in your printing but with less of a coating of ink.Įxperience will help you determine which mesh counts you prefer to use on individual projects, but there are some guidelines that will help you get started with using different mesh counts.
The mesh count indicates how many fibers there are in one square inch of the screen, so a 160 mesh count screen has 160 fibers in one square inch of the screen. Understanding screen mesh count begins with understanding what the count means. With that in mind, we’re providing a primer to help you better understand mesh count and know where to start when trying ou different mesh counts for different types of prints. The right mesh count can go a long way towards producing the results you’re after.
