Sometimes the screen printing business becomes unpleasant, especially when the screen printing quality of your machine falls. It happens as you face some usual 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, continuous movement of the screen printing press would make the screws 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 a must in quality artwork. Your process of 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 get printing products with a suitable registration, you must strictly separate colors.
Proper Curing | Test Each Run of Products
More than arranging and operating a dryer is required to ensure 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 print, 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 whether 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 awaiting 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 making available on single sort of screen. But you can get several having standard 110, below 400, and over. A lower mesh count is adequate for most jobs. On the other hand, comprehensive screen prints need better screens.
Besides, the exact screen selection verifies the screen tension previous to starting printing. Eventually, the pressure on screens can loosen, which can be the reason for trouble, together with blurred prints or rough-feeling ink on your ultimate 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 significantly impacts the deposit position of ink. This impact arrives from the pressure of push 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 on the screen during the printing process, the squeegee will be taken hold at a 45-degree angle, or the ink will not go 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. Usually, by making the angle higher, a smaller amount of ink will be printed onto the substrate, and the lower angle results in more ink for printing.
The aim is to offer adequate force to deposit a smooth ink coating on the substrate. Overpressure might cause a bend in the screen, blur the print or depart behind a large amount of ink. More pressure is needed to push good ink from the first to the last of the screen, which may bring an incomplete or pale print.
Set up appropriate Off-Contact.
To obtain a brittle screen print on your ultimate printing job, you should set a suitable off-contact before starting printing. Off-contact refers to the space between the screen and the pallet underneath. It permits the screen to approach quietly in getting in touch 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-contract area of 1/16 inch; for printing on thicker substrates like sweatshirts, your off-contact space will be nearer to 1/8 inch.
Proceed with Test Run
You are to test previous to every screen printing job server. Your test run will ensure that your registration is spot on, your press (has been) set up correctly, screens (are) stretched and dirt free, and the dryer is entirely curative inks. It’s better, easier, and less costly to provide adjustments following a test run than to cancel some or total screen printing products.
The time you spend on a test is to be treated as better spending. By arranging appropriate graphics, set up, method, and testing, you can be optimistic that your screen printing machine will offer high-quality screen printing products per your clients’ demands.
