The below guidelines are as mentioned by Spreadshirt. We very much want you to go by them.Without which we cannot upload them to our shop.
There are two types of designs – Vector and Pixel , you can make your artwork accordingly.
- Save vector designs as .eps
- Only elements which are part of the final design should be included in your uploaded file.
- All elements which should not appear in the design, such as backgrounds, should first be removed before submission.
- Save pixel designs as .jpg, .gif, .png, or .bmp
- Size of pixel designs: max. 10 MB and min. 200 dpi (buttons: 400 dpi)
- Pixel designs may not exceed 3000 x 3000 pixels
Also please mention the number of colors if you want to upload a vector graphic.
Requirements for Vector Designs
In order to use plot printing, your vector design must follow a few guidelines (check the FAQ below) i.e. comply with the minimum line thickness, have minimum negative space, have no more than three colors and no color gradients.
The Spreadshirt Team will review whether or not you have met these requirements before approving your design for release. Most designs are reviewed within 2 business days. If your design does not meet the given requirements, we will send you an e-mail informing you that it has been denied.
Requirements for Pixel Designs
It is currently only possible to upload pixel designs into the T-shirt Designer. By submitting your pixel designs, you assure that no third party rights (copyrights) have been violated. Any designs with violations will be rejected and an e-mail will be sent to you. More information on pixel design requirements can be found in the below helpful FAQ .
- Q:How do I create a vector design that will meet all the requirements for a plot printing (Flex / Flock) format?
A: Vector designs can be created with Corel Draw, Inkscape, or Adobe Illustrator. Please take note of the following tips:
Convert all design elements and text into curves (paths.)
The first step is to delete all pixel (bitmap) information. Do this by selecting the pixel information and pressing the delete button on your keyboard. After the pixel information has been deleted, you will need to select all of the design elements (Ctrl A.) Then in the top menu bar, go to Object/Flatten Transparency. On the settings, slide the bar to 100% vector, and check the Convert all Text to Outlines and also check the Convert all Strokes to Outlines . Next, go to the Pathfinder and click on the Merge option. If you don’t see the Pathfinder palette, go to Window/Pathfinder. To finish up, go to Object/Path/Clean Up, and check all three boxes and click OK.
Corel Draw The first step in Corel Draw is to open your Object Manager from the Tools, so that you can see all elements of your design. Second, delete all pixel information by selecting the bitmap element (shown in your Object Manager,) and clicking on the trash can at the bottom of the Object Manager window. Select all design elements, right-click, and select convert into curves . Delete all empty , or no-fill curves . Then select all curves of the same color by pressing the Control (Command) key and clicking on the curves of the same color. Once these curves are selected, combine them by right-clicking and selecting combine , or use the key command Control (Command) L. Repeat this step until all colors have been combined into one curve per color.
Proof the minimum size of the object
After the conversion into curves (or paths,) it is necessary to proof every object in the design for a minimum size of .06 inches. It is helpful to draw a small circle or square with dimensions of .06 in. x .06 in. and drag it over the thinnest elements of the design. If the design element is larger than the .06 in shape, then the design will be able to be printed. If the design element is smaller than the .06 in. shape, then the design will not be able to be printed.
Save/Export designs as .eps
Only elements which are part of the final design should be included in your uploaded file. All elements which should not appear in the design, such as backgrounds, should first be removed before submission. Before uploading, your design should be saved or exported into .eps format.
When using Adobe Illustrator, go to File/Save As, and select EPS (make sure the box for "include CMYK PostScript in RGB files" is unchecked before saving.) When using Corel Draw this can be done by going to File/Export/Encapsulated PostScript (EPS.)
A common mistake occurs when the pixel design is opened in a vector graphic program (such as Adobe Illustrator or Corel Draw,) and is then saved with the .eps file extension. This does not mean the content of the .eps file is vector, it is still a pixel design and will need to be vectorized before saving.
- Q How do I create a pixel design (e.g. from a photo) that meets all requirements for digital printing?
Printing on Clothing
A: In order to have a digital image printed successfully, your design must
- be saved as .png, .jpg, .bmp, or .gif (transparent formats, i.e. .gif or .png, are preferred)
- be at least 200 dpi
- not be larger than 4000 x 4000 pixels
- not be larger than 10 MB
Be aware that the design size should fit by 11.8 x 11.8 inches. Minimizing the design is always a possibility without losing picture quality, however, enlargements are not since the design will appear "pixelated".
