Xen White Plastisol Ink Xen White Plastisol Ink is high opacity, creamy, optically bright and at right viscosity (good consistency). Xen White is a non-phthalate plastisol ink that fuses between 330-350F. Xen-White is recommended for cotton and 50/50 cotton/polyester.
Plastisol Ink Application Recommendations.
Most printers prefer 110 mesh especially when they are printing dark shirts. Since Xen White is very thixotropic in nature(thins down with stirring or mixing- you may need to mix it before using), you can use higher mesh count as Xen White passes through finer mesh easily. Due to its properties of being less gummy and thixotropic, you may find least ink accumulation on the sides.We recommend Xen White without thinning down; but you can add ink reducer, especially when printing spun or combed cotton shirts. We also suggest using 70 durometer squeegee. we have seen printers using 60 or 80A and some have reported using 70A beveled squeegee with great results- remember by using beveled squeegee you apply the lesser amount of ink.
On automatic machines, we recommend triple or double durometer squeegee. For lighter shirts, you may be able to use only one coat on 110 mesh of Xen White for the coverage here it is important to note that you use a higher solid emulsion such as one part QXL at 45% solid or TEX, a dual cure diazo emulsion at 46% solid, to achieve a higher EMO (Emulsion over Mesh) that would yield a better "well or reservoir" for thicker ink deposit on the fabric. But if the fabric is rougher, such as black or dark color carded cotton shirt allow two coats, use Xen White as is and put two coats with 110 mesh count with an off contact angle of 1/8 and possibly higher newtons for the screen tension above 25 & Plus some. One of the most important factors is the pressure applied as you are pushing down the ink onto the fabric. It depends on factors such as the emulsion film, off contact angle, type of squeegee and the pressure being exerted.
The issues are the proper and optimum ink deposit and the release from the screen that depends on the type of ink you use. It is important to have a soft ink at a right viscosity and that is what you will find with Xen White Then there is always the subject of how much pressure and pull or push the ink. This is where the experience of the printer counts, that you are very cautious of fiber matte down and ink not looking fuzzy.
Xen White ink is recommended for cotton and 50/50 cotton/polyester. Xen White is a low bleeding and not a non-bleeding ink- That does not mean that the dark bleeding type shirt would not bleed. Use Mustang White to avoid bleeding. For dark fabrics, we suggest to use 110 mesh count for better coverage. It is advisable for bleeding type dark shirts that one should give a proper test to make sure of non- bleeding effect of any ink before going to production. The other important factors are that the migration and sublimation both occur at 300F - So that the flashing should be done between 200-250 F and dryer should be maintained, for bleeding issues, below 300 F. Usually, low fusing inks are being used in that situation.
Stretch fabric after printing both ways to make sure that the ink is fully cured. If ink cracked or did not stick to the fabric that means that it was not fully cured.
- wet on wet printing
- matte finish
- Optical brightness
- Right consistency
