Plastisol based, light-reflective ink for enhanced visibility and novelty type designs. For printing on smooth, absorbent, jersey-knit fabrics such as t-shirts and fleece goods.
Flash-Back ink is an easy to use, one-part, plastisol ink that contains millions of light-reflecting micro spheres. In daylight the ink appears to be a normal print, however, in low-light conditions it reflects light back toward the light source (Retro Reflective). The average candle power (CP) of a properly printed and cured Flash Back ink is approximately 40-50cp. This is well below that of an ANSI rated safety requirement of 450-500cp. Therefore, this product is recommended for fashion and novelty use only. You must stir Flash-Back inks well prior to use and periodically re-mix during the print run as the components within this ink will settle out over time
Opacity: Flash-Back are transparent and colors will not provide 100% contrast when printed onto dark colored or black garments. However, reflectivity will not be affected. Mesh: Print through a 110 thread/inch mesh (43 metric) monofilament. Coarser meshes may reduce reflectivity. Stencils: Use any direct emulsion or capillary film. Capillary films should be 50 microns or less in thickness for best results. Printing Instructions: Do not print Flash-Back on top of a plastisol under base. If under basing is necessary for brighter daylight viewing and fabric is dischargeable, use Union’s DSPP-1003 Discharge White or DSPP-9050 Discharge PrePrint Clear. Review the DSPP-Series Technical Data Sheet for further information on the proper use of discharge products. Additives: Flash-Back inks are supplied ready to print. After thoroughly mixing, if ink appears to be heavy in viscosity only small amounts Union’s PLRE-9000 Cureable Reducer/Detackifier should be used. Curing Instructions: These inks will cure at 340° F (171° C). Because of the reflective nature of the ink, it may require a longer curing time and more heat to reach the proper temperature. Flash-Back inks must be fully cured on first pass through conveyor oven as re-curing is rarely successful. Washability: Flash-Back ink series has limited washability. While results may vary, a Flash-Back print will lose some reflectivity, approximately 5%, after the initial wash cycle and possibly slightly less with each subsequent wash cycle. Wash-Up: Clean the screens and squeegees with mineral spirits or any Eco-Friendly screen wash designed for plastisol inks.Recommendation:
Caution: Always test this product for curing, adhesion, reflectivity, crocking, opacity, washability and other specific
requirements before using in production. Flash-Back does not meet the requirements of the National Fire Protective
Association (NFPA) for Fire Department Safety or “Turnout Gear”. Only Union’s Flash-Trans Reflective Transfer System or
approved reflective tapes and fabrics should be used for this type of application.
Union Ink does not knowingly add plasticizers containing the phthalates listed and outlined in California Bill 1108, CPSIA HR-4040 and Oeko-tex Standard 100. The plasticizers identified may include di-(2-ethylhexyl) phthalate (DEHP), dibutyl phthalate (DBP), benzyl butyl phthalate (BBP), diisononyl phthalate (DINP), diisodecyl phthalate (DIDP), di-n-octyl phthalate (DnOP), (DIBP) Di-iso-butyl, and (DMP) Dimethylphthalate, including esters of ortho-phthalic acid and are not direct ingredients in the manufacture of our Non-Phthalate Inks. Union Ink does not test the final product for amounts of the aforementioned phthalate plasticizers and esters and encourages all users to conduct testing for their intended use.Disclaimer: Not all Union products are available in every country.
