To determine whether there is an actual visible difference between 150 and 300 dpi, it’s important to keep in mind the printing method and the size your final work will be displayed at.

All-over printing (sublimation)

The printing method is called dye sublimation. In this process, the inks are gassed onto the garment using heat presses, so when the ink is gassed, it covers the entire surface of the garment. Even low-resolution files or files that were resampled and thrown into a 150 dpi template, don’t seem nearly as low quality in this print as they do on the screen. This is why having a 300 dpi file won't have a big impact on the quality of sublimation products.

Where does resolution make a difference?

Mugs - Our templates were recently updated to 300dpi. Although 150 is okay, the smaller details there are, the higher the resolution should be. Mugs are being looked at up close, which is why you want to ensure that your files are high quality.

Shirts - Similarly to the mugs, you may want to create these files at 300 dpi to ensure it prints nice and crisp.

Please note that our generator is set to 150 dpi. We keep it this way because not everyone is an expert and they may just want to print an image that they can’t change the resolution on.

We use genuine Brother GT-3, water based pigment inks. GT-3 inks are CPSIA compliant and Oeko-Tex™ certified, which means they are safe to print on youth/children’s clothing and reduce environmental waste. Also, GT-3 inks provide a high washing colorfast AATCC rating of 4.

For posters, we use Epson UltraChrome water based HDR ink-jet technology.

Yes, inside and outside labels are $2.50 per shirt! For either type, the maximum print area is 3x3 inches. Check out examples of custom inside and outside labels in this branding guide.

Inside labels are available for select apparel products with a removable "tear-away" label. Find unisex and men's tshirts with a tear away tag here, or use the left toolbar to search for women's shirts.

Outside labels are available for all other brand t-shirts (except racerbacks) that don't have a removable "tear away" label.

When you submit an order, you'll see the option to upload an inside or outside label print file, depending on the shirt model.

Our standard process is the Direct to Garment (DTG) method of printing. That means we can create photo quality prints, the amount of colors used doesn't affect pricing, and there aren't any order minimums. We use Kornit and Brother printers for all DTG printed garments.

Our experience shows us that DTG printed shirts are just as durable as screen printed shirts when it comes to washability.

A white under base isn't printed on white garments. Because under base is white ink, it'll print on other garment colors when a print file design includes the color white. It may also be used if the print file design doesn't include the color white, but is generally lighter than the garment color. Depending on the design, white under base may not be printed on all garment colors.

There aren't many things our incredible DTG process can't achieve! However, when choosing the colors for your artwork, it’s important to note that they may look different on a real product than what you see on your computer monitor. Even if you have calibrated your monitor to a specific color profile, there are various factors that influence the final appearance of colors on a printed product. Because of this, we can’t guarantee color accuracy 100%. Consider the following factors:

• When printing on garments, it’s important to consider fabric material and garment color. The same color value will look a little different on when printed on 100% cotton vs. a fabric blend. Similarly, the same color value will look different when printed on a light vs. dark colored garment.
• We also print a white under base layer beneath prints on colored garments so that the colors look vibrant and stand out from the fabric. The same color value on one garment can look different when printed with vs. without a white under base. We've taken some photos where you can see how the same color values look different when printed on a white or black garment. Keep in mind that even the colors in these photos look different than on the original printed product. Referencing these photos is not a substitution for ordering color swatches on a sample product.
• The two most popular color spaces are RGB and CMYK. RGB has a wider gamut (the range of colors that can be expressed) and print files made in RGB can be saved as png files. CMYK, on the other hand, is the color space used when printing. Our printers automatically convert your submitted print files from RGB to CMYK, and this conversion changes the color gamut. That's why we suggest you design your file within the CMYK color space, but convert the file to RGB before saving. For best possible accuracy, convert the file to sRGB color profile, sRGB IEC61966-2.1 to be exact.  This way your colors will stay within the gamut. Most editing programs have this color profile as default.

DTG printing process is best suited for garments that are 100% cotton. So if you’re looking for the most opaque result, 100% cotton is your best bet. This fabric generally has a better result due to its tight weave. However, there are exceptions to this. If a cotton is too thick, it can absorb the ink and result in a more faded look (for example, the Gildan 2000 is a thicker cotton).

We also offer printing on poly blends and tri-blends. Our fulfillment team has worked hard to develop a system that allowed us to print on such garments without compromising print quality. Due to the looser weave and combination of fabrics, these garments will have a faded/vintage outcome with DTG printing. This is a pretty cool effect, but may not be ideal for you if you want a more opaque outcome.

All-over printing or sublimation is a printing process where your design is printed on paper with dye ink and then transferred directly onto the fabric with heat. Sublimation lets you cover all of the garment with your design instead of, for example, DTG printing that has a smaller area to work with.

Due to the peculiarities of the sublimation process, graphics may shift up to 2 inches when printed. Because of this, we don't recommend using designs that require precise placement. Canvas Devil carries two types of products that are printed using sublimation:

• Sublimated products. These products are pre-made, so your designs are transferred on a ready-made product. Sublimated products, might show white streaks and creasing that are most common near stitching (for example, the sides of a towel).
• All-over print products (also referred to as cut & sew products). In this case, your designs are printed on fabric, which then gets cut and hand-sewn into the product you ordered. These products don't have white streaks.

When unpacking a new shirt or hoodie with a direct-to-garment (DTG) print, you might notice a vinegar-like smell or an off-white residue. Don't worry, that's not unusual - it's from a fixation agent applied during the printing process and it's not permanent.

Fixation agent (sometimes known as pre-treatment) is used for all DTG prints across the industry. It helps the ink bond with the fabric, and without it, the ink would flake off the garment. The solution is simply to wash the garment! Neither the residue nor the smell is permanent and both should go away after one wash.

These are a few basic terms to help you get started:

Resolution is the measure of pixels in the display, usually expressed in measurements of width x height. For example, a monitor that is 1920 x 1080 is 1920 pixels across and 1080 pixels down.

DPI (dots per inch) is the number of dots in a printed inch. The more dots the higher the quality of the print (more sharpness and detail)

The actual size is best described with (you guessed it) actual numbers. Let's say you have a 5x5" (12.7x12.7cm) shape at 100dpi, but you need to make it a 10x10" (25.4x25.4cm). If you simply scale it to twice its original size you go from 5x5" (12.7x12.7cm) to 10x10" (25.4x25.4cm). Since the size has now doubled, your resolution has been cut in half - that particular part of your graphic, is now 50dpi.

When you're submitting your print files, we ask that they're at least 150dpi and at actual size. The resolution of any file is only as good as the dimensions.

DPI (Dots per Inch) is the number of dots in a printed inch. Computers display and print images in small dots, so the more dots the image has, the higher the quality of the print (more image sharpness and detail). The fewer the dots, the blurrier the image. See the images below:

120 DPI: the penguin on the right is where we want you to be from the beginning. While 150–300 DPI still is the amount to strive for, 120 DPI is a good amount of dots to produce high–quality prints.

60 DPI: the penguin in the middle is the case where our designer team comes to use. We can make images with 38–74 DPI two times larger, and you no longer have to upload new image to meet our DPI requirements, and your image is adjusted to meet our print requirements. Please remember that we “adjust” the image by using existing information to add the “new information.” Some details in your image may look a bit different.

30 DPI: your order will be placed on hold until you upload a new image which meets our minimum requirements for printing.

Yes, you can. As the guidelines suggest, shirt artwork is optimal at a minimum of 150 DPI. We do accept higher resolution files, but it is best not to exceed 300 DPI. For faster processing and accurate prints, we recommend that the final artwork be submitted at a minimum of 150 DPI resolution, but we do also accept 300 DPI files.

Please save your file using "Save as", because saving files as "Save for Web" will automatically decrease the graphic's resolution to 72 DPI. This may result in low quality and sizing issues with the final print.
