Optimizing Your Design Files

We want to make sure your Artist Shop designs look as amazing on your products as it does on your computer. Here's a guide for everything you need to know to maximize vibrancy by optimizing colors in your design and create a design file that makes your printed design simply awesome.

What is On-Demand Printing?

On-demand printing is a method where a digital printer is used to print a design directly onto a garment using inkjet technology with direct-to-garment (DTG) or sublimation printing. Picture a futuristic inkjet printer the size of your bathroom that costs more than a house! With this process, the inks are absorbed by the fibers of the garment. Imagine an inkjet printer, but using a blank garment instead of paper- and that’s essentially how on-demand printing works.

Why On-Demand Printing?
Since on-demand printing uses a digital printer, it has  less color limitations than screen printing, which allows for more versatility since you are not required to match colors by inks and pantones. Because of this, the print stays pretty close to true color. Additionally, with on-demand, customization is super simple. Since you are able to print an image directly on a garment, on-demand does not require any up-front investment, inventory commitments, or set-up requirements. on-demand printing helps us invest more in artists and less in inventory, providing more opportunities for artists to be creative and take design risks while giving them more canvases to explore.

Colors

The DTG Color Spectrum

Here’s a full color spectrum printed on DTG. As you can see, the hardest hues to hit are the  bright reds, cyans, and greens. Let’s explore quick spectrums of these three colors with provided RGB values.

Let’s use this Color swatch template as our reference for this next part. You’ll be able to pull this into Photoshop for easier visuals. On this template, the top row of colors starts with a solid color, and each swatch after it is a % transparency of that color. On the bottom row is if the color was solid of the same value of the above color, but if you were to lay a white background behind it and use the eyedropper in photoshop to get the solid hex value.

Here are some printed versions of this template:

On a black garment:

On a heather gray garment:

And on a white garment:

Note that on white all colors fade naturally because prints done on white shirts do not use an under base. Designs on other colors will use a white under base that will make your transparencies fade out to a lighter color as opposed to a darker one.

Since DTG files are printing in RGB, it’s difficult to achieve super bright and neon CMYK colors. Here are our RGB suggestions to achieve those  neon and pastel colors:

Black inks on DTG

“True Black”

Although the  true black is usually #000000, achieving this on our DTG printers is a bit different. The way to get a nice dark black, especially on lighter garments, is with the CMYK values 55,55,55,100, respectively.

White Transparencies on DTG

Here is a spectrum of different percentages of opacities of white ink so you can visualize how it will print. Our recommendation would be that you stay above 30% opacity, as you can see it is barely visible at any percentage lower than that.  whitetransparency

As you can see, any transparencies lower than 30% are either super faint or don’t show up at all –  keep that in mind when designing!

On-Demand vs. Screenprinting

Let’s explore the differences between these two printing methods.

You Are My Universe by Lim Heng Swee

Above is the original art file we used to print (sans background). Now let’s look at a side-by-side of the design printed by both on-demand and screenprinting.

Let’s take note of the pros and cons of each: 

  • On-demand prints colors more accurate to the original art file, whereas screenprinting has to find the closest pantone match which can cause a bit of variation. If you’ve ordered a reprint of a tee you’ve owned in the past, this is the cause for the variation – on-demand will match the artist’s original colors, whereas the old shirt contains colors we thought were the closest pantone matches. 
  • Saturation is much higher in screenprinting. While on-demand can achieve nice and bright colors, there are certain hues (i.e reds) that will print a little bit more toned down. (See color section for more details)
  • Halftones with higher frequencies can be achieved nicely on screenprint, but can get lost with on-demand because of their small size. With on-demand, we’ve found that frequencies less than 25LPI prevent the largest loss of details.

  • On-demand can more accurately depict details without the compromise of knocking a design down into a certain number of colors. This particularly favors heavily colored and illustrated designs, gradients, and even photography!

Inks

What types of inks do we use?

All of the inks used in our on-demand printing are water-based. They do not contain PVC, phthalates, or AZO dyes.

Why does my shirt smell a little funny?

That odor you may smell on your new tee is a by-product of the custom printing method used to print the design. The odor from printing is just a temporary addition. Now that your tee is out of the confined space of the shipping bag, the printing smell will dissipate after a few days and a wash cycle.
