colors used whenever possible. If the job calls for flashing after each color on a T-shirt, the same will hold true for cap printing. Think through the print sequence in advance and work out all the details before you start printing the job. The flat- and curved-cap printing methods also require two different screen types. Making screens for flat-cap printing involves the same process as making a screen for T-shirt printing, except the scoop coater is smaller to accommodate coating smaller screens. Capillary film also is a popular method for coating cap screens since the smaller screens can be difficult to coat with direct photo emulsion. Making screens for curved printing entails direct coating with a 3-inch scoop coater or using capillary film cut to the size of the cap frame. A wide variety of screen mesh counts can be used when printing flat caps, since squeegee pressure can be increased if more ink deposit is needed. This is not the case when printing on a curved surface, and you should select meshes in the 86110 range to allow the ink to easily shear from the screen. This minimizes the need to double-stroke the print on the curved surface. Use minimal squeegee strokes when printing on a curved surface to reduce the chance of printing a "double image" or smearing the print. Registering the screens for flat-cap printing is easy, but setting up a press with curved screens takes a little more practice. This can be accomplished much more easily if a pin registration system is used because there is less room to move the screens left to right when registering the job due to the curvature of the screens and substrate. With a pin registration system, all the film positives for a multicolor job are aligned in advance and taped to individual clear carrier sheets. Next, the carrier sheets (with the design attached) are placed over two pins on the exposure unit with the cap screen positioned over these same Use Info*Action #23 at impressionsmag.com/infoaction See us at ISS Nashville impressionsmag.com April/May 2015 | Impressions 59http://www.pepcopoms.com http://www.impressionsmag.com/infoaction http://www.impressionsmag.com
