7031 Ultra White™ is a high performance, high pigment, fast flashing, low tack, non-phthalate plastisol screen printing ink.
7031 Ultra White™ is very creamy, short bodied, and very opaque, resulting in excellent coverage on dark garments.
Formulated for high definition and resolution, fine detail and halftone printing.
This product will spot dry, with a very low after ash tack. Dwell time is dependent on the spot dryer used. In some cases, you may have to lower the heat of the spot cure unit because too much heat may actually make the ink tacky. When you spot dry, you are only partially fusing or gelling the surface of the ink. The ink should just dry to the touch, with no lift o , but not totally fused. Totally fusing the underprint white may cause inter-coat adhesion problems with the inks printed on top of the white ink. Final fusing or curing occur in the dryer.
7031 Ultra White™ offers some bleed resistance, but it is not a non-bleed ink. On some types of fabric, bleeding or dye migration may occur. Always test print the fabric to be printed before beginning production. It is best to do some long term testing on some fabrics to determine if they are going to bleed. Bleeding or dye migration may not occur right away.
Adjust squeegee pressure, angle and off-contact to insure proper shear and letdown of printed ink. Excessive squeegee pressure will drive 7031 Ultra White™ through the fabric being printed, making the ink look less opaque. Proper settings of squeegee, flood bar and off-contact will improve performance, improve performance, improve screen life and squeegee durability.
7031 Ultra White™ is very easy to print when compared to other white inks and can be printed through finer mesh counts while still maintaining great opacity. This means reduced ink usage and faster production times, a real money saver. Using finer mesh counts also means a softer hand on the finished product.
Adding any reducers or additives can lower the bleed resistance, opacity or increase cure times of ink. STIR the ink prior to printing on press and after addition of reducers or additives.
Test dryer temperatures and wash test printed product before and during a production run.
