A heat gun or a heat strip is suitable equipment to test the ink at the moment of its getting out of the dryer.
It is to be considered that the inner ink hotness wants to attain its curing warmth in addition to the exterior ink. It is better to check each and every printing work whether appropriately cured. There will be no fracture or strip on the print to be supplied to the clients. Keep the cured & cooled products stretch till the ink stretches slightly.

If you push ink on the screen during 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 working the ink in the direction of you on the screen of the squeegee position should be 45- to 80-degree angle. Usually, making the angle higher, smaller amount 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 coating of ink on the substrate. Overpressure might cause bend the screen, blur the print or depart behind much amount of ink.
