make consistent matches in order to take advantage of the way index dots build up on press. Next, determine the size of index dot the screen department can hold. This question is trickier and will probably require a test or two to get right. To do so, take a simple gradient line and duplicate it in Photoshop or CorelDRAW. Convert it to different resolutions of index halftone dots (see Figure 1, page 56). Typical resolutions that work well are 150 to 220 dpi. Any higher than 220 dpi requires the use of very tight screens, perfect emulsion coating, and a very high mesh count to make a decent print. A good average guess to aim for is 190 dpi. But, if you can go higher, it may make sense. Whether artwork is a good fit for an index print can be a guessing game as well. Some artwork that is apparently better suited for traditional halftones can come out fantastic in an index dot screen print. Other designs that look like they were made for index dots end up looking too grainy or posturized. A general rule is to use index dots for designs that have a grainy look—artistic drawings, paintings, and hand-done details. Also, designs that contain very small type that will be printed in halftones are a good candidate for index, as are graphics with small details that are important, such as people's faces. And, in cases where there is already a "noise" style effect on top of a graphic without a lot of gradients, index again excels. The reason it does so in these cases is that the small details do not have to be rendered with holes in them like they do when using traditional dots. They are instead made up of square dots that are stacked next to each other without surface-area loss to the image. However, designs that contain transparent overlays, long smooth gradients, and lots of shadows that have deep details are not good candidates for index separations. Also opt out of index if the best results require a lot of colors, or in the case of designs that have large areas of flat, blended spot colors (colors that have to be made from the combination of other colors).
