If you are looking for the "One White Ink To Rule Them All
" then look no further that the new International Coatings Cool White
. Cool White is a true "universal" in that it is a white ink that is specially formulated to print on cotton, blends, and polyester garments. It is a low bleed, fast flashing, low tack, flexible curing, non-phthalate plastisol screen printing ink.
Cool White has a creamy viscosity with a great body, making the ink suitable for printing on auto and manual presses, and offers superior performance over a wide range of
substrates, including standard textiles along with hard to print
promotional items.SPOT DRYING
Cool White will spot dry, with a very low after flash 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 be just dry to the touch, with no lift off, 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 should occur in the dryer.IMPORTANT INFORMATION
Cool White is an ultra low bleed ink, 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 fabrics to determine if they are going to bleed. Bleeding or dye migration may not occur right away.
Cool White was formulated to make printing opaque white easy. Hand printing is less tiring because less squeegee pressure is needed. The result is increased operator performance. Automatic equipment can be adjusted to lower squeegee pressure settings, thus improving screen life, squeegee durability, and overall print quality.
Cool White can be cured from 275°F to 325°F (135°C to 163°C), giving the operator greater flexibility and energy savings. This low curing range makes this a great ink for poly materials that can release dye at higher temperatures causing dye migration discoloration.
Cool White, when compared to other opaque whites, prints so easily that you will find that a finer screen mesh can be used with the same opacity as a lower, more open mesh. This means less ink will be used; a real money saver in terms of ink usage and cost per print. It also means a softer hand on flashed fabrics.
Adding any reducers or additives can lower 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.
