So, you just got your FN-INK... Now what do you do?
So you just got in the New FN-INK plastisol ink line. You are excited and are ready to print up some art and see just what the ink can do for you. So, where do you start? What do you need to know about the ink? Do you need to do anything special to the ink? Screen prep? What about cure? Is it low bleed? The following blog will answer all those questions and more.
What is FN-INK?
FN-INK is many things, but it is not everything. FN-INK hits many of the needs that we as printers have for successfully printing t shirts.
- FN-INK is low cure - 260°
- FN-INK is low bleed when cured at low temps.
- FN-INK is High Opacity.
- FN-INK prints wet on wet.
- FN-INK is creamy and short bodied.
- FN-INK is made for you the printer that is tired of paying for high priced plastisol ink.
But more than any of that, FN-INK has been made because it is Financially Necessary that this ink line exists.
FN-INK is: Low Cure
That's right, not only is FN-INK less expensive than our competitors, it's low cure as well. Typically this is an ink property you end up paying more for. But it's all part of this package. Once the entire ink film, alllll the way down to the t-shirt, reaches 260° it is cured. This means a couple of things.
- You can potentially run your dryer faster allowing you to print more shirts per hour.
- You can run your dryer at lower heat settings. This will allow you to save some cash on electricity and potentially keep your shop a bit cooler since you can run your dryer far cooler.
- If you only have a flash unit and you use it for cure, it is now FAR easier to achieve full cure of the ink.
*Cure is attained when the ENTIRE ink layer reaches 260°. This means 260° all the way to the bottom of the ink layer. Using a laser gun to read the surface temp can be misleading as you will need to read a surface temp as much as 60°- 80° above what cure temp is. This is due to the rate that plastisol ink absorbs heat, the length of your tunnel, and the thickness of your ink deposit. Thinner ink deposits heat up faster than thick deposits. A good example is printing black ink VS doing a print/flash/print of white ink. White ink will be far thicker and take up to twice as long to reach full cure compared to the thinner black ink deposit. When changing your dryer to low cure temps, do wash testing to ensure your new dryer settings are reaching full cure.
FN-INK is: High Opacity
For a Financially Necessary, low cost ink, these inks have a surprising amount of opacity! You can achieve bright colors on darks with a print flash print. As always, not every color is reproducible on dark garments. Some of the more translucent colors like Navy or Fuchsia will have some shirt showing through no matter what. But colors like Golden Yellow, Bright Red, Lt Royal, etc are remarkably bright.
FN-INK Does: Wet on Wet Printing
Wait… High opacity, low cure, and wet on wet able? Are you guys making any money off this ink? WOW. Yep, this is a high opacity wet on wet able ink, right out of the bucket.
We recommend 230 mesh screens or higher for the best wet on wet performance. While you can get ok wet on wet performance through 200 mesh, the possibility of laying down too much ink is increased the lower you go in mesh count. At a certain point you are just unable to control your ink deposit well enough.
FN-INK is: Low Bleed - Because of Low Cure
Yup, if you are able to keep temperatures low in your dryer and cure closer to 260°, you can keep the dyes in the polyester fabrics from bleeding into your inks. To quickly understand why this happens. Most polyester fabric is dye/temperature set between 270°-300°. What this means is that, when the polyester thread hits that temperature again, the dyes return to a gaseous state and are absorbed by the plastisol inks. This is why there are low bleed inks on the market.
But as stated above, if you can cure your ink below the bleed point of the poly thread, you do not have to worry about dye migration!
FN-INK has: Creamy Ink Consistency
This is a departure from the inks that Ryonet has been selling. The ink chemistry in the Lava series is a longer bodied ink, which means it has some length when pulling it from the bucket and is a bit thicker when cold.
FN-INK is a shorter bodied ink which cuts and therefore, shears easily, when an ink knife or a squeegee passes through it.
What this equates to on press is:
- Less dot gain because you can use less pressure to clear the screen
- Greater perceived opacity because of, again, the ability to back off on the pressure needed to clear the screen
- You can print the ink when it's cold and still great a great look.
- The ink is more consistent from beginning to end.
