![]() Eventually there will be a history of documented settings to be able to adjust the dryers quickly as the relative humidity changes so curing the ink is not a problem.Ĥ. Relative Humidity: This is very important for use in the future. Slower speeds = higher temperatures faster speeds = lower temperatures.ģ. Belt Speed: This will be changed often to allow either more or less heat to be absorbed by the shirt. Temperature Setting of Dryer: This will probably not be changed often.Ģ. The following is an outline of the testing information to be entered and the procedures to be used for the tests:ġ. Long jobs run on automatic presses should be tested on an hourly basis. Again, these tests need to be run before the shirts are printed.Īfter that, tests should be conducted at the following times: first thing in the morning just after the first break just after the second break. Note: the last three tests are for poly/cotton shirts. Hang these examples on the wall so they can be used for comparison by others. You will now have the results of a print with ink that is definitely not cured and one that definitely is. Run the tests again and compare the results. Next, take the same garment and run it through the dryer several times until it is scorched. That done, run all of the tests listed on the form. Before using this form in actual production, however, you need to run two tests.įirst, print a shirt, but do not fully cure the ink by keeping the garment temperature below 250☏. The important thing is to catch these flawed garments prior to shipping, if possible.Īt the start of a production run, the first thing to do is obtain the form to be filled out over the course of the run. It is possible that some flaws will fall through the cracks, but that’s to be expected. It may not feasible to inspect each garment at this time, so as they are being put on press, they should also be inspected as much as possible. Recording the results is generally not done unless the garments are expensive or there is an excessive quantity of seconds. This should be done as they are removed from their packages. Prior to conducting any tests comes the inspection of garments. All results of the tests need to be documented on proper forms and filed for review in case of a problem. In order to have an effective quality-control program, it is necessary to establish the various tests to be performed and know how to judge the results of the tests and the number of times per day that these tests need to be performed. There are a number of “tests” that should be conducted constantly in order to ensure that the garments you deliver are to the customer’s satisfaction and to the standards the company requires. In order to have a quality control program, we have to examine where things can go wrong and be able to test and document results once standards are established. Screen printing has its challenges, but that’s what separates the good from the excellent. Quality control is an essential part of growing any manufacturing business and maintaining customer satisfaction and loyalty.
