The optimal resolution to use is 180 dpi to match the nozzles per inch. Anything more than this, and you wouldn't notice a difference; anything less and you could lose detail and quality. There are other factors that the printer uses to achieve optimal results, so the print head nozzle count per inch doesn't necessar- ily mean one printer is greater than another. For instance, just because one print head has only has 150 nozzles per channel in a linear inch doesn't mean that it can't achieve the same results as the 180 nozzle per linear inch print. The purpose of the nozzles in this instance is to have a baseline to generate your artwork resolution. LIGHTS, DARKS, AND MIDTONES One of the biggest challenges of inkjet printing on fabric is in re- lation to midtones. Midtones are simply the tonal value between your darkest and lightest areas of an image. If there isn't a great difference between the dark areas and midtones or the light areas and midtones, your print will blend too much and not stand out. Until you begin working with correct midtones, you may not even notice this is an issue. Certain RIP programs can correct some of the midtones for you, but it's always better to visually Adjusting the levels allows you to create a more dynamic graphic. Use the preview to slide the tones up and down to see the instant effect of these changes on the screen.
