What is Vector Art?

What is Vector Art?

Vector art is created using specific software programs, such as Adobe Illustrator or Corel Draw. These programs use geometric points, lines, and shapes to create art that is clean, camera ready, and can be scaled infinitely, without any loss of quality. A Bitmap logo or JPEG/PNG is made of pixels, which becomes very blurry and distorted as you enlarge the image.

In the demonstration below, we designed our logo using both formats and then zoomed in.

In the Bitmap art, the edges of the art become distorted when the picture is enlarged.

With art such as sponsor logos, we will need Vector art to achieve the proper print for your shirts.

How can you tell if your art is Vector Art? One good indicator is the file type. Vector artworks are usually created in Adobe Illustrator, and are commonly saved as specific file types. The four most common Vector file extensions are .ai, .pdf, .eps and .svg.

Unfortunately, just because a file is saved in one of these formats, does not mean that it is vector art. Sometimes, people open and re-save the file in a Vector format, without recreating the art using the vector editing tools. Only art originally created in a vector-editing program, such as Adobe Illustrator, is truly Vector Art.

Without a copy of a vector-editing program, you can’t truly verify if an image is or isn’t Vector Art. PromoSpark understands this limitation, so we provide this service, free of charge.

Industry Info – Using Glow-in-the-Dark Ink

Whether it’s a bright, green cartoon on a child’s shirt or an eerie rock band’s brand on a hoodie, one of the coolest effects in screen printing is the use of glow-in-the-dark ink.

Let it Glow

Phosphorescent ink gets its luminosity from phosphors – a chemical that stores energy and radiates it out as a glow. Phosphors can be added to ink in a powder or you can buy ready-to-use glow-in-the-dark ink.

Printing Tips

  • Phosphorescent ink can be used on white and colored tees. If printing on a colored tee a white underbase will need to be used.
  • The more glow-in-the-dark powder used and the heavier the ink deposit, the longer the product will glow.
  • Most phosphorescent pigments will have a green glow, but some suggest adding fluorescent ink to change the hue. Glow-in-the-dark pigments can be produced in many colors. The human eye is however most sensitive to green light, meaning that green glow appears brighter and is generally favored by screen printers.

Industry Info – What is a Half Tone?

A half tone is a printing technique where small dots of solid color are used to create a blending or gradient effect. We use half tones in our custom artwork to add dimension without adding cost.

For example, below is a screen printed t-shirt design for the Making Strides Against Breast Cancer walks.


If you take a closer look, you can see that small dots of solid pink and solid blue overlap to create the illusion of a gradient of purple.


This is an effective way to add depth, blending and shading onto a custom screen printed shirt design. To design your shirts online visit PromoSpark’s Design Studio.

Spring Trends for 2016

Spring is approaching which means new trends for 2016! Bold color choices, new technology and everyday functionality will hold the spotlight in 2016.


Color Trends: Bold & Bright

Neutral and earth tones are a thing of the past. Consumers want to stand out in vibrant hues. Colorful tanks, bright tees and printed hoodies are making a strong appearance.

According to Margaret Crow, marketing director at S&S Activewear, “Logos printed over these sublimated styles really pop. It’s a very ‘now’ look”.


Another trait consumers are looking for in their wearables is useful technological attributes. Golfers enjoy caps with performance enhancing features like cooling and moisture-wicking materials. College students are looking for a softer hand with combed ring spun cotton.


Versatility is arguably the biggest trend on the market. Everyone wants to make the most out of their clothes. Durable fabric and a style that goes from errands to lunch and beyond will make choosing custom printed apparel easier for the consumer.

PromoSpark’s website is packed with on-trend versatile, functional, and bright clothing. Visit www.PromoSpark.com to design your custom apparel now!
