Methods of Instruction Course assignments information provided via written handouts. Teacher lectures and demonstrates each process, including rationale, set-up, printing and cleanup. Discussion takes place during the demonstration as teacher poses questions and scenarios, and as students anticipate issues based on experience. Students then perform individual hands-on activities with artwork they have generated in response to assignment criteria. Teacher/Teaching Assistant circulate among working students to answer questions, guide and provide assistance as needed.
Methods of Evaluation of Student Performance Student maintains a written log of variables for each assignment, as is commonly done in industry setting. Teacher supervises lab activities and observes student performance. Each student turns in log along with printed work samples for evaluation and assignment of final grade.
Assignments Simulated Embroidery Assignment: Develop a two- or three-color T-shirt graphic (image w/text or text only) using layers of puff inks, so that the design appears to be embroidered. You may create the artwork by hand or using a computer.

Steps to Follow (Artwork): • Develop your type/graphics. Keep all artwork bold. • Place a sheet of vellum or frosted acetate over the artwork. Using an opaque pen, create a “stitch” printer. Draw a series of parallel or zig-zag lines, extending them about 1/32” beyond the edges of the type or line work. This makes stitches appear to wrap around type layer when overprinted. • A third option is to create a highlight stitch printer. Pretend a strong light source is hitting your artwork from one side. Develop a highlight of smaller lines, covering about 1/3 original area. • While this can all be done by computer (by creating a stitch pattern and using a step and repeat function), the random look of hand drawing more closely simulates the stitched texture of embroidery.
Steps to follow (Screen Prep): • Use the following meshes for printing: 1st screen: 60 - 74 mesh for solid background type or color areas; 2nd screen: 160 - 225 mesh for the “stitch” printer; 3rd screen: 125 mesh for the highlight printer. • Coat first screen with 3 standard coats. Let dry and add 2 additional coats to print (flat) side. Coat stitch/highlight screens 1x2 coats only. • Let dry and expose, being careful to register artwork.
Steps to Follow (Inks): • Use puff/blow-out inks for all layers. Dark, “jewel” tones are recommended. Highlight printer can be silver with about 10% of first color printed. • Create a puff from regular ink by adding puff base at a 50/50 ratio.
Steps to Follow (Printing): • Set all screens to slight off-contact, so that ink will shear when printed, transferring to the garment completely but just at the surface of the print. • Print 74 mesh first, flash until puff comes up slightly all over printed area. Let cool. • Next, print stitch screen(s). Do not flash, just run through the dryer. • Dryer should run at 340º for about 45 sec. (4 or 5 belt speed). Test inks!
Notes: • If initial puff inks are not cured (risen), they will continue to rise in the dryer and swallow up the stitch and highlight printers. • Run tests and keep careful notes on flash times and temperatures. Once you perfect your “system” for this process, it will be easy to duplicate.
4-Color Process for Textiles
Assignment: Design a full-color graphic, separate into four-color process, prep screens and print. This is a high-end process that will require your utmost attention to detail! Every variable you know of in screen printing is at play here.
Scanning Procedure: • Scan artwork as provided by instructions in computer lab. Follow the details carefully. • Print all separations in black ink only, on vellum. • Print the channels at the indicated angles to avoid moiré in your finished print: yellow channel at 35 dpi at a 0º angle, magenta channel at 35 dpi at a 75º angle, cyan channel at 35 dpi at a 15º angle. • Use register marks and color bars on each layer. • Ask Lab Assistant for help if you need it!

Job Set-Up: • Rule of mesh: dpi x 4 = tpi Screens should all have same mesh (between 200 – 225), at same tension (15 – 25 N/cm). • Keep emulsion coat thin (1x1, opposite directions). The fine dots will not burn properly if the emulsion varies in thickness! • Wash screen out thoroughly. Do not miss areas or your image will be compromised. • Tape and block out carefully. Leave register marks exposed for first few prints and then tape off. • Pre-register and register on press CAREFULLY!! • Use hard, sharp squeegees (90+ duro).
Printing/ Ink Considerations: • Make sure the inks you are using are not contaminated. Make sure all tools are extremely clean: paint sticks, squeegees, etc. • Inks should be on the thin side. If a color prints too strong, you may reduce with plastisol halftone base or manufacturer’s reducer. Do not mix between brands! You will need to experiment with this part of the process, it takes a lot of practice to evaluate the intensity of the color. • Remember that these are TRANSPARENT inks. Every change in squeegee activity (speed, angle, number of passes, flooded or not flooded) will change the deposit of ink. All printing must be done consistently to insure consistent results.
