Design Upload & Creation

Designs are your money makers. If you truly want to maximize your profits, you’ll need to be aware of the proper file requirements, quality standards, and legal logistics. In this section, you’ll learn all about uploading and maintaining your designs.

How do I upload my designs?

Upload your designs by following these simple steps:

  1. Open the SPOD app and click on blue “Add product” button in the upper right-hand corner
  2. Click on the Upload button located in the vertical left-hand column of the design tool
  3. Choose one of the uploading options (Upload an image, Facebook, or drag & drop from your computer)
  4. Designs can be deleted from the library. Existing products featuring the deleted design will not be affected.
  5. Your designs can be added to the Customizer so that customers can create personalized products with it.

Uploaded images will be represented by thumbnails and will be stored in the upload section of the design tool. Please note: if the quality of your uploaded image does not meet the requirements defined here, you will receive a warning, and the image will not be available for print.

What are the print file requirements?

Pixel designs

Pixel graphics are multicolored images or photos composed of individual pixels (picture elements). The pixels are arranged in a grid, hence the term "grid graphics" (sometimes called "raster graphics"). Each pixel is assigned color information, the sum of which produces the picture. With SPOD, pixel graphics serve as a template for digital printing. So that we can achieve the best possible result in printing with your graphics, please bear in mind the following tips:

Requirements for your pixel design

  • PNG, JPG, BMP or GIF file format
  • Maximum file size 10 MB
  • Image resolution at least 200 dpi for apparel
  • Image resolution at least 400 dpi for non-apparel
  • Maximum size 4000 x 4000 pixels
  • Design is isolated

Optimizing image resolution

Photos or graphics in PNG, JPG, GIF or BMP formats consist of pixels (picture elements) arranged in grid form, each of which is assigned multiple color information. The number of pixels in width and height also later determines the size of the print.

We print textiles at 200 dpi. The abbreviation dpi stands for dots per inch, and this provides information on the density of the picture elements. A graphic that is 1000 pixels wide, for example, produces a design 5'' wide when printed at 200 dpi. A 2000 pixel-wide graphic produces a 10'' wide design, etc.

A design with a low pixel width or height (for example, 800 x 600 pixels) cannot therefore be easily enlarged without loss of quality (for example to 4.7" x 4" or more). Because of the "missing" pixels, the print would probably look blurry and out of focus. So only upload designs with sufficient resolution and number of pixels. We recommend 200 dpi and a maximum of 4000 x 4000 pixels, so as not to exceed the maximum file size of 10 MB.

Removal of unwanted backgrounds

People frequently want to print a motif cut out of a photo or picture, and not the background itself. But it is not enough simply to create a white background, because this will mean that a white area is printed, which will be visible on both colored and white products. Backgrounds must be transparent so that they are ignored by our printer. Isolate your motif in a graphics program and save it as a PNG. Perhaps the following instructions for removing the background from a motif in Photoshop will be helpful:

Removing the background with Photoshop

  1. Open your pixel graphic in Photoshop.
  2. Select the "wand" tool.
  3. With the wand, select the area to be removed, e.g. the background.
  4. Remove the selected area (with "del").
  5. Repeat the process until the background is completely removed.
  6. Make sure that all areas of the background have now really been removed. Zoom in to see if small groups of pixels still remain at the edges. Remove these if possible.
  7. Save the isolated graphic in PNG format. If this format is not an option when saving, change the color space under "Image -> Mode" to RGB color space. This is important because some file formats, such as for example JPG, do not recognize transparent surfaces and provide the isolated image with a white background when you save it.

Removing the background with GIMP

  1. Go to the Layers Palette (on the right side. If it is not there go Window > Layers - Brushes). If the name of your file is Background, then it will need renamed by right clicking on the name and choosing ‘Edit Layer Attributes’. Change the name to anything.
  2. Next make sure that the image is in the RGB color scale. Select ‘Image’ from the top menu, then select ‘Mode’ from the box and make sure RGB is selected.
  3. Create a new layer that is transparent. Right click on your original layer and choose ‘New Layer’. Under Layer Fill Type, choose Transparency. Click OK.
  4. Click and drag your now transparent layer (which should look like a checkerboard) underneath your original layer.
  5. Right click your top layer and click ‘Merge Visible Layers’. In the pop up box click Merge.
  6. Select the ‘fuzzy select tool’, the first row, second tool from the right in the tool bar.
  7. Set the threshold (located under Tool Options in the Toolbox) to around 15.
  8. Click anywhere in the background and hit ‘Delete’ on your keyboard. This should reveal a checkerboard.
  9. Go Select > None to deselect the ‘marching ants’.
  10. Export the file as an PNG image. File > Export.

Speckling color transitions

Digital printers work in a similar way to inkjet printers: the ink is sprayed directly onto the product. To achieve the highest possible fidelity to the colors of the design, a white layer is first sprayed onto colored products as a base. If your design has a transparent color transition running to the edges, this white base can show through on dark products. To prevent this, use the "speckle" tool in your graphics program. Advanced users can also use the "dither" function.

Taking color differences into account in CMYK and RGB mode

Pixel graphics are printed onto shirts in CMYK color mode. However your screen displays the motif in RGB mode. This may make the colors look different. Colors are often brighter on the screen than on the printed shirt. In order for the colors of your printed shirts to have a similar intensity to the colors on the monitor, you should set the contrast of your graphic higher and the colors bolder. Read more about the different color effects on the monitor and shirt.

Vector design requirements for printing:

  • We support SVG, AI, and CDR file formats.
  • Your design must not exceed 15 x 15 inches. We recommend 11 x 11 inches as the ideal size.
  • Lines and other parts of the design must have a diameter of at least 0.06 inches.
  • Maximum 3 colors: we can print up to three colors with vector files as plot print (flex, flock, special flex). Vector files with more colors will be printed with Digital Direct.
  • Please create each color in your design as a separate layer.
  • All objects and text to be printed must be converted into paths.
  • Make sure that all curves are completely closed and do not overlap each other

Please note: if the vector file is printed as a plot print (flex, flock and special flex printing), an extra $2.50 / 2,50€ will be added to the product price when they are selected. This is a one-time charge per product, not per design or print area.

Measuring and increasing line thickness

If parts of the design are thinner than the required line width, they can tear during weeding making the print motif unusable. If gaps in the motif or whole parts of the motif are too small (e.g. dots), they may possibly be overlooked during weeding or be difficult to detach. In addition, fine lines do not adhere as well to the shirt and may peel off. Lines and other parts of the motif must therefore have a diameter of at least 0.06 inches and gaps between elements should be at least 0.04 inches.

This is how you measure line width: to check whether the lines in your motif are thick enough, create a circle with a diameter of 0.06 inches and lay it on top of the thinnest line in your motif. If the circle fits inside the line without protruding, it is thick enough. Do the same with a 0.04 inch diameter circle to measure the gaps in your design. If the circle fits inside the narrowest gap, it is big enough.

Important: if you increase the line width, make sure that your overall design is no larger than 15 x 15 inches. It is best to aim for a size of 11 x 11 inches, so that it fits on most of our products.

Checking and closing curves

Ensure that you do the following:

  • Check that you have really converted all the parts of your design into curves. Unconverted elements will not be printed, as our printer will not recognize them.
  • Check that you have really closed all the curves in your design. You can use the "combine" or "merge" function in your graphics program to do this.
  • If there are any remaining elements which overlap or are not required, remove them.

Don’t forget about these important details…

  • Your design is clear, detailed and sharp
  • Contrast and brightness are optimally adjusted
  • You only use images that you own. For example, do not depict someone else’s face or something that may result in a violation of personal rights

Templates to download

With our templates, you can easily prepare your design for poster printing. Each template contains:

  • A layer to show you the correct size
  • A red-marked margin of 2 mm to indicate which area might be cut off

Open the template with Photoshop or any graphics software suitable for .psd files. Then follow the checklist for poster printing (see below).

Format Europe North America*
  Photoshop Illustrator Photoshop Illustrator














*If you are using the US version of the SPOD app, please use the templates marked North America. The sizes are adjusted to meet US standards (inch).

Checklist for poster printing

Choose and download a suitable template, open it and drag your design to the files work surface. Then proceed as follows:

  1. Your design is in the "Your Design" folder
  2. Your design fills the layer exactly (the edges disappear below the red line)
  3. The red border doesn’t cover any important elements
  4. The "Tutorial" layer is deactivated
  5. The “Bleed allowance” layer is deactivated (no red margin visible)
  6. RGB is selected as the color profile
  7. Once you’re all set here, save your design under "File > Save As" in .png format.

Handling and packaging of posters

Express or premium delivery is unavailable for posters. Prints in the size of 8" × 8" (20 cm x 20 cm) and 8" × 12" (20 cm x 30 cm will be dispatched in a sturdy envelope, sizes 16" × 24" (40 cm x 60 cm) and 24" × 36" (60 cm x 90 cm) are rolled in a cardboard tube.


Differences in Colors: Monitor vs. T-Shirt

Colors may look different on the printed item than they appear on your monitor. This may be due to different reasons:

  • To print pixel designs, we need to render the color scheme from RGB to CMYK and make color corrections if necessary. This may lead to slight color variations.
  • Every screen displays colors differently. A combination of brightness, contrast and saturation can change color effects significantly.
  • The color of the fabrics has an effect on the print result. The example below illustrates how different colors come out on white, black and different-colored fabrics.

What is the difference between vector and pixel designs?

Vector graphics

The image represented by a vector graphic is composed from geometric forms like points, lines, circles or curves.The image displayed is mathematically defined using these geometric forms. This is how a vector graphic can be enlarged (scaled) without a loss of quality, as the image is recalculated each time the size is changed.

Vector graphic files can be created with graphics software such as Adobe Illustrator, Corel Draw or Inkscape. 

In order to ensure the highest compatibility, please save your vector graphics in the format .eps.

Pixel graphics

A pixel graphic is a computer graphic in which the image is represented by raster forms made up of pixels (points of color). Each pixel represents one color. When a pixel graphic is enlarged, the individual pixels are also enlarged. Therefore, the more the image is enlarged, the more it will look coarse, angular or "pixellated”.

Pixel graphics serve as the master copy for digital printing at SPOD. We recommend saving pixel graphics in the format PNG. A graphic’s resolution is given in dpi and represents the number of dots per inch.

Why was my design rejected?

We can only accept designs that meet certain quality criteria. We will reject designs (prior to production) if any of the following reasons apply. If you have any questions as to why your design was rejected, please get in touch with our legal service:

Bad resolution

Pixel graphics should be of sufficient quality to realize good print results. Please make sure your designs have sufficient resolution and aren’t pixelated. Find out more about pixel graphics requirements herein the “What are the file requirements for print?” article.

We cannot accept designs with a background (except for non-textiles such as mugs, bottles, etc.). Please make sure to rid your design completely of its background, remaining pixel artefacts or sloppy borders.

Highly personal design

Please don’t include any designs with highly personal or specific content like names, birth dates, email or website addresses. We cannot accept these types of designs.

Design mark

SPOD reserves the right, in its sole discretion, to reject any design based on alleged or suspected copyright infringement.


Semi-transparent designs will result in poor digital direct printing quality on colored products. Digital direct printing requires spraying a base-layer beneath the design to increase color contrast and to better bring out the colors. Semi-transparent designs would make this sub-layer visible and create an unpleasant gray fog. Try adding flecks of color to the appropriate areas of your design.


SPOD reserves the right, in its sole discretion, to reject any design based on alleged or suspected trademark infringement

Design is blurry

Blurry designs or designs lacking sharpness will not be cleared since printing is likely to return poor results. Find out more about pixel graphics requirements here.


Wrong vectorization

If you vectorized your design automatically, it is possible that some areas came out untidy. Sometimes edges are rounded, parts are deformed, or anchor points are newly set. This may lead to unpleasant shapes or irregularities displayed in a font.

Contrast issues

Low contrast designs are often hard to make out and are likely to return poor print results.

Violation of content guidelines

We reject designs violating our content guidelines if they contain illegal content, hate speech, pornography or glorified violence. We also reserve the right to remove sensitive content or restrict its visibility if it defies child and youth protection, or if it benefits the demands of our diverse community.
