Hi-Square ink, when printed correctly, will produce a print with an extraordinarily thick ink layer that retains sharp edges and crisp, highly detailed definition even after curing. The colors in this system are based on the standard Mix-Opaque colors. This is not puff ink. For satisfactory results with this ink, the screen printer must use them in combination with a correctly prepared screen and a carefully adjusted printing technique.

 

SPECIFICATIONS:

OPACITY: Excellent opacity.

PRINTING INSTRUCTIONS:
Use a sharp 75-80 durometer squeegee. The squeegee angle and pressure must be adjusted so the ink prints a clean sharp image, but is not pushed into the fabric. Use a slow speed on both flood and print strokes. The off-contact distance should be as small as possible. Adjust the speed and angle of the screen lift so that the screen breaks away from the print immediately behind the squeegee on the print stroke. This is critical for a clean sharp print stroke with a minimum of ink retained in the mesh. These inks should be printed last in the color sequence. If this is not possible, they should be flash cured before the next color to maintain the three dimensional effect.

SCREEN FABRIC: Use 60 to 110 monofilament polyester depending on material being printed. For best results the mesh should be tensioned to at least 24 newtons.

SCREEN COATING, FILM, BLOCKOUT: To achieve the desired three dimensional effect, this ink must be printed through capillary stencil that are at least 400 microns thick. Stencils of 700 microns or over are recommended.

DRYING TIME: U3DSQ Series plastisol inks will not air dry. They must be heat cured. Normal plastisol inks will fully cure and withstand repeated washings when the entire ink deposit reaches 320 F. Poor washability can usually be traced to under curing.

MODIFIERS: The use of modifiers is not recommended with this ink. Occasionally, in order to obtain a sharper print, a very small amount (1-2 %) of Viscosity Reducer (UPLUS-9000) may be added.

WASHUP: T-125 mineral spirits, or biodegradable washes
SYS-2500, SYS-2550 or SYS-2510 screen wash gel.

ALWAYS TEST PRINT BEFORE PRODUCTION
