Printing on dark garments with a white ink can be difficult. Sometimes the tagless label is simply not bright enough and the darkness of the garment shows through. Here at Inkcups Now, we understand your frustration and have provided some great tips for you to get that white bright!

To get a brighter white:

try reducing your thinner mixture by 5%.
The mixture commonly use is:

50 grams White
7.5 grams SBM thinner (15%)
2.5 grams 1000HNX hardener (5%)

Add a 1 second delay before pickup and 1 second before print. Adjust front and back delay to see if you get improved results.

Make sure you increase the pad compression on the garment so the pad “over-compresses” or nearly stalls during the printing cycle

Make sure your pads are not worn

Make sure you used enough ink in the cup – it is a common problem to put too little ink into the cup with white because its pigments are so heavy. 50 gram of white ink is a minimum mixture

If you have artwork flexibility, go to all capital letters for size and country of origin

It is common to have to add thinner more frequently to white ink because it has more pigment than all the other colors. The thinner helps keep the pigment in solution.

Try using inks other than standard white ink – Inkcups Now has developed a new product called SuperWhite Ink with pigments especially designed for garment printing.
