Sometimes, the screen printing business can become unpleasant, especially when the screen printing quality of your machine declines. It occurs when you encounter common difficulties, such as blurry imprints, smudged ink, and improper registration.
Besides, images vanish while washing those. These misdeeds result in additional expenses. Even spoiled the printing business due to the severe business impression. However, to get rid of these problems, practice the following measures-
Verify Your Screen Printing Machine before Starting the Work
Blurred imprints might be the outcome of loose screws. Usually, the continuous movement of the screen printing press causes the screws to loosen.
These pins keep the pallets, as well as screens, in place properly. As a result, the pallets and the screens start twisting during printing, and the significant effect of such twisting is the outcome of blurred prints.
Use Quality Graphics to Improve the Screen Printing Quality
Curing your ink is essential for producing high-quality artwork. Your printing process is going very well. But rather than high-resolution images, you couldn’t hope to avoid the substrate being fuzzy. At the same time, you should separate the colors properly. To obtain printing products with suitable registration, you must strictly separate the colors.
Proper Curing | Test Each Run of Products
More than arranging and operating a dryer is required to ensure that it is appropriately cured. More than 320 degrees of heat is needed for nearly all plastisol inks. You should follow the curing temperature instructed by the manufacturer. More heat with a more extended period is required for thicker prints, but a lighter one needs less effort. A heat gun or a heat strip is suitable equipment to test the ink when it comes out of the dryer.
The inner ink’s hotness wants to attain its curing warmth in addition to the exterior ink. It is better to check every printing work to ensure it is appropriately cured. There will be no fracture or strip on the print VPS to be supplied to the clients. Keep the cured & cooled products stretched till the ink stretches slightly.
The simplest way to check your curing is with a stretch test: Stretch the cured and cooled shirt, and see if the ink stretches slightly. The ink should not show signs of cracking. If you are trying out a new ink or a new dryer, perform more thorough testing of your curing by washing a shirt several times to ensure the ink holds.
Provide Accurate Screens and verify Your Screen Tension.
Different screen printing jobs require screens of changeable mesh counts. Frequently, printers are sold with a single type of screen available. However, you can get several with a standard 110, below 400, and over. A lower mesh count is typically sufficient for most applications. On the other hand, comprehensive screen prints need better screens.
Additionally, the exact screen selection verifies the screen tension before starting printing. Eventually, the pressure on screens can loosen, which can be the reason for trouble, along with blurred prints or a rough-feeling ink on your final product. Several screens can be tightened. At the same time, others may need to be replaced.
Arrange the exact Squeegee Angle and Pressure–
An angle is used to hold the squeegee. The manual screen printing machine has a significant impact on the deposit position of the ink. This impact arrives from the pressure of pushes or pulls on the squeegee.
The angle at which you hold your squeegee while manual screen printing can significantly impact your ink deposit, as can the pressure you exert on the squeegee while pushing or pulling. If you push ink onto the screen during the printing process, the squeegee will be held at a 45-degree angle, or the ink will not pass through the screen to the substrate. On the other hand, to pull with the working ink in your direction on the screen, the squeegee position should be a 45- to 80-degree angle. Typically, increasing the angle results in a smaller amount of ink being printed onto the substrate, while a lower angle yields more ink for printing.
The aim is to offer adequate force to deposit a smooth ink coating on the substrate. Overpressure may cause a bend in the screen, blur the print, or leave a large amount of ink behind. More pressure is needed to push the ink evenly from the first to the last line of the screen, which may result in an incomplete or pale print.
Set up appropriate Off-Contact.
To achieve a brittle screen print on your ultimate printing job, you should set a suitable off-contact before starting the printing process. Off-contact refers to the space between the screen and the pallet underneath. It permits the screen to approach quietly in contact with the substrate at the moment of printing and pulling away, producing an exact print-on-contact on the back.
The same off-contact space depends on your substrate. For most t-shirt screen printing machines, you need to set an off-contact area of 1/16 inch; for printing on thicker substrates, such as sweatshirts, your off-contact space will be closer to 1/8 inch.
Proceed with Test Run
You are to test the previous server for every screen printing job. Your test run will ensure that your registration is accurate, your press has been set up correctly, screens are stretched and dirt-free, and the dryer is entirely free of curing inks. It’s better, easier, and less costly to provide adjustments following a test run than to cancel some or all screen printing products.
The time you spend on a test should be treated as valuable time. By arranging appropriate graphics, setup, method, and testing, you can be confident that your screen printing machine will produce high-quality screen printing products that meet your clients’ demands.
