Whether you use a conventional exposure system or a digital screen imaging system, the savings can be eye-opening. For ex- ample, say a screen printer prints 485 shirts per hour and makes a profit of 75 cents per shirt. If the press averages three setups per day at an average setup time of 30 minutes, the profit per hour while printing is $360. It should go without saying that the reve- nue per hour while not printing is zero, so the daily profit lost to setups is $540. Even a 50-percent reduction in setup time results in enough additional print time to generate another $275 per day in profit. DAVE ZIMMER, M&R COMPANIES I'm interested in offering spe- cial effects printing to my cus- tomers, but I've always had the impression that the inks are difficult to work with. What challenges do special effect inks offer vs. traditional plastisol or water-based printing? Special effects inks have unique characteristics, but as long as you are aware of them and prepare accordingly, they do not have to be any more dif- ficult to print. The first rule of thumb when adding them to a design is to treat them as a highlight or spot col- or. You do not want to use them for intricate or fine-line artwork with a lot of detail. You also want to add them to a design keeping in mind that they "move." Puff inks spread out. High density rises straight up, HD clear melts and spreads, and some bases retract when cured. Make sure you are using the correct mesh for the special effect ink being printed. Your manufacturer will recommend a specific mesh count range, and you also have to take into consideration resolution, edge definition, and mesh bridging. Also keep in mind that you will need to use a thicker stencil as you need to deposit a thicker layer of ink than usual in most cases. One option is to use a capillary film ranging between 100 and 250 microns. Other emulsions can be applied more than once to build thickness, but long drying times can be a challenge.
