Screen Printing is the most versatile of the commercial printing processes and choosing the right ink for Outdoor Stickers is important.
Screen printing covering a wide range of applications and substrates there are many factors to take into consideration when choosing an ink for a particular application. One ink cannot meet all the finishing requirements, for all end users, on all substrates.
Since we specialize in selling and producing stickers, window vinyl, floor graphics, and many other pressure sensitive vinyls, this article will look at the important factors about choosing the correct ink for these applications.
Pressure Sensitive Vinyl
Pressure sensitive vinyls have a Pressure-sensitive adhesive or PSA (self-adhesive, self-stick adhesive). This is an adhesive which forms bond when pressure is applied to marry the adhesive with the adherent. No solvent, water, or heat is needed to activate the adhesive.
It is used in pressure-sensitive tapes, stickers, labels, note pads, automobile trim, and a wide variety of other products. Usually these products have a liner, that when removed, reveals the adhesive.
Typically, the pressure sensitive vinyls that we produce require the product withstand outdoor durability or wear in tear, like in a retail environment.
It is critical that your printer offers a comprehensive selection of UV screen printing inks that excel in these environments.
We are dedicated to offering screen printing inks that help our customers achieve higher levels of economy and performance, along with special formulations to meet unique requirements and applications.
For products like stickers and other pressures sensitive vinyls, we recommend a UV Screen Ink has been specifically designed for applications on pressure-sensitive decals.
For the best possible outcome, you need an ink that exhibits excellent exterior durability and chemical resistance. Generally speaking, our UV inks have an outdoor durability of 3+ years depending on color and if lamination is used.
Laminating a sticker increases the outdoor durability up to a few years.
Lighter colors like yellows and oranges tend to fade faster than darker colors. And with fluorescent colors, consider this your warning. Fluorescent colors fade quickly with outdoor exposure and are not recommended for outdoor durability.
Hold Up During Finishing
Another important characteristic is that the inks will uphold through all different types of finishing processes, including:
- Digital cutting
- Die cutting
- Accept pre-mask for “die cut” stickers
- React well with clear gloss coat
We offer a variety of different finishing options when it comes to inks including:
- Transparent inks
- Matte finish
- Clear gloss finish
These are all very important details when it’s important for your job to achieve a specific finished look.
Pantone Matching System
When choosing the right color for your custom print job, we refer to the Pantone Matching System or PMS. Also referred to as the Pantone color or Spot Color.
We provide FREE PMS Color matching. Just provide a PMS color code and we will be happy to provide a color swatch.
Printing Inks in the Right Order
For face up decals we print the inks in order from lightest color to darkest color. Conversely for face down decals we print inks from dark to light.
Quoting Your Job
To get the most accurate print quote, we need to determine how much ink will be used for a specific job. To do so we calculate the percentage of total ink coverage of each color.
This is a major factor in quoting your job.
