When I print my shirt, my image seems to be a little blurry.
Again this can be caused by a number of things: Are the screens tight in their clamps and the micro registration tightened? As you print the force will alter your screen’s position on the print surface. So, if the clamps holding your screens are loose then your print will be out of registration. This would especially be true on 1 colour prints.
Are the platens secured to the press and have you applied a good amount of tak to hold the garment in place. If you are using a flash, and after your second pull or colour it is burring, then the flash could be shrinking the shirt, thus distorting your print. Also if you flash for two long between colours you will start to cure the ink which can result in blurred / poor print quality.
Has your screen mesh lost it tightness? The screen needs to be tight so that your image is tight. Time to restretch.
Is your mesh count and squeegee right? It can be surprising how much of a difference this can make when printing.
