We simply built the solid area by selecting our rectangle tool and drew a box in a spot color. Next, we opened our art template and copied and pasted our gradient bar above the area box. To create a grayscale, we drew a box and left it at a 100 percent transparency, copied and pasted it in front, then dragged it next to the original and changed it to 90 percent transparency. We repeated this process until we got down to 5 percent transparency. Using our type tool, we labeled the percentages above each box. We then took our bullseye/registration mark and set the line weight to 0.25 points and copied and pasted it in front. Like the gradient bar, we repeated this process sev- eral times changing the stroke as needed. Finally, we added verbiage with our type tool and our fancy el- ephant logo at the top and we were ready to make screens. We outputted at 55 lpi (lines per inch) at 22.5 degrees with a round shape on our comput- er-to-screen (CTS) unit. We picked 225/40 (225 threads per inch with a 40 micron thin thread) as our mesh count and took extra care in preparing these for testing. The emul- sion was a water-resistant du- al-cure we post exposed after developing a good exposure. Using our Thickness Gauge, we accurately measured our EOM percentage, or emulsion over mesh percentage, check- ing for consistency at 18–20 percent so one screen wasn't transferring more or less prod- uct from the other. All ten- sions were at 28 N/cm and all 65/90/65 squeegees were brand new and sharp. During testing we controlled the room temperature and hu- midity and measured both the whole time. Dryer and product temperatures, belt speed settings, platen temps, squeegee and flood speeds, pressures, and angles were all con- trolled and consistent. To accommodate multiple tests at the same time, we built a small divider down the middle of the screen so we could test two products at a time. We also doubled up art on the top and bottom of the screens so we had one sample for us to keep for reference and one for the client. We end- ed up with a great flipbook showing all the informative results. In all, we repeated the entire process eight times on what seemed like 18,000 colors. Once the printing and curing was com- plete, we cut each piece out of the finished shirt and sorted all the different products in the same color ways and shipped the com- pleted project to the client. Here is their response. Gotta love a reorder. And fortunately this testing process shouldn't be near as difficult the second time around. continued from page 16 PRODUCT HIGHLIGHTS Welcome to the PRODUCT HIGHLIGHTS section where each month we offer you resources to enrich and expand your business with great services and products from our advertisers. brand new and sharp. During testing we Lon, Thanks so much for the great testing done for the discharge program. We are in the process of creating a chart based on the information you provided. We are trying to keep it as simple as we can using an A–B–C rating system. (A being good, C being not recommended). I realize this is somewhat subjective. If you have a few minutes, can you take a look at the chart and see if you agree/disagree with any of our ratings? We don't want to mislead any printers. Also, there are five colors that we missed, and there are seven new colors we are adding for 2016 that we did not have in inventory of but we do now. I would like to send these to you for additional testing. (Colors oxford, neon pink, and blaze orange will almost definitely be a "C" rating so I'm not sure they need to be tested?) Thanks for your help and partnership, Jeff
